None so blind …

…. as those who choose not to see!

Note: This is a long and pretty depressing post yet one that contains a critically vital message. Just wanted to flag that up.

This is not the first time I have used this expression as a header to a blogpost. The first time was back in August 2013 when I introduced the TomDispatch essay: Rebecca Solnit, The Age of Inhuman Scale.

I am using it again to introduce another TomDispatch essay. Like the Solnit essay a further reflection on the incredible madness of these present global times.

But before getting to that essay let me refer to a recent Patrice Ayme post. It is called: New Climate Lie: Magical CO2 Stop Possible.

Patrice included this graph:

To Stay Below 2C, CO2 Emissions Have To Stop Now. We Are On The Red Trajectory: Total Disaster
To Stay Below 2C, CO2 Emissions Have To Stop Now. We Are On The Red Trajectory: Total Disaster

Adding:

Tempo depended upon the CO2 concentration, pitch upon the Earth global temperature, distortion upon the energy balance on land in watts per square meter. The numbers used were past and anticipated. After 2015, the graphs became two: one was red, the bad case scenario, the other was blue, and represented the good scenario.

As I looked at the blue graphs, the optimistic graphs, I got displeased: the blue CO2 emissions, the blue temperature, and the blue power imbalance, had a very sharp angle, just in 2016. First a sharp angle is mathematically impossible: as it is now, the curves of CO2, and temperature are smooth curves going up (on the appropriate time scale). It would require infinite acceleration, infinite force. Even if one stopped magically any human generated greenhouse gases emissions next week, the CO2 concentration would still be above 400 ppm (it is 404 ppm now). And it would stay this way for centuries. So temperature would still rise.

The composer, who was on stage, had been advised by a senior climate scientist, a respectable gentleman with white hair, surrounded by a court, who got really shocked when I came boldly to him, and told him his blue graph was mathematically impossible.

I told him that one cannot fit a rising, smooth exponential with a sharp angle bending down and a line. Just fitting the curves in the most natural, smooth and optimistic way gives a minimum temperature rise of four degrees Celsius. (There is a standard mathematical way to do this, dating back to Newton.)

Read Patrice’s essay in full here.

However, I find the malaise gripping us in these times to be infinitely more difficult to understand than what is or is not mathematically possible. I just can’t get my mind around the possibility that we are in an era where greed, inequality and the pursuit of power and money will take the whole of humanity over the edge.

Why, for goodness sake, is the U.S., my adopted home country, pursuing gas exports? As I read here: United States On Path to Becoming Major Exporter of Natural Gas Despite Climate Impacts
Here’s a taste of this report from Julie Dermansky of Desmogblog:

But rather than acknowledging the climate risk posed by further expansion of LNG export infrastructure, the U.S. Congress and the Obama administration are moving in the opposite direction.

The natural gas export industry may grow even more rapidly if the first new bipartisan energy legislation drafted since 2007 passes. The Energy Policy Modernization Act of 2015, known as S. 2012, would expedite permitting for LNG export terminals.

The bill’s passage was considered imminent until it derailed with the introduction of an amendment that would provide emergency aid towards solving the lead-contaminated water crisis in Flint, Michigan. Now the passage of the bill hinges on whether the Senate will come to terms on aid to Flint.

Lobbying for the bill has been heavy. As DeSmog’s Steve Horn reported: “The list of lobbyists for S.2012 is a who’s who of major fossil fuel corporations and their trade associations: BP, ExxonMobil, America’s Natural Gas Alliance, American Petroleum Institute, Peabody Energy, Arch Coal, Southern Company, Duke Energy and many other prominent LNG export companies.”

I highlighted the name ExxonMobil in that extract because that company is the subject of Tom Engelhardt’s essay from Bill McKibben. Republished here with Tom’s kind permission.

Loving our wilderness

Loving our wilderness is another vital loving relationship

I quite deliberately named today’s post so that it would extend the theme of loving relationships posted yesterday.

So the recent announcement from the White House, “White House announced President Obama signed proclamations Friday to protect almost 2 million acres of pristine lands.” is to be welcomed with open arms. The article published in The Press Enterprise explained that those millions of acres were in California.

President Barack Obama established three national monuments today, Feb. 12, that cover almost 2 million acres in the Mojave Desert, the White House announced.

Obama used his power under the Antiquities Act to sign a proclamation designating the Mojave Trails, Sand to Snow and Castle Mountains national monuments. The move bypasses similar legislation, introduced by Sen. Dianne Feinstein, D-Calif., that has languished for years in Congress.

Feinstein asked the president in August to use his executive power to create the monuments. She praised the action in a statement: “I’m full of pride and joy knowing that future generations will be able to explore these national monuments and that the land will remain as pristine and as it is today. To a city girl like me, this expanse of desert, with its ruggedness and unique beauty, is nothing short of awe-inspiring.”

While on the subject of California, there is more good news from the Canis lupus 101 blog.

Wolves get a grudging welcome from Northern California ranchers

By Tim Holt February 11, 2016

Wolves such as OR 25, a 3-year-old male, have crossed the Oregon border, and Northern California ranchers are preparing to accommodate them.

We are going to have a viable population of wolves in the far northern reaches of California, and it will be with the grudging cooperation of our ranchers.

That was the takeaway from a public hearing held last month in Yreka (Siskiyou County), where the state’s Department of Fish and Wildlife invited public comment on its draft plan for accommodating our new four-footed residents, and where there were as many Stetsons in the audience as you’d see at a cowboy poetry convention.

Where are the wolves?

premium_landscapeYes, there was some foaming at the mouth, some evidence of the government-hating libertarianism this region is known for. “We don’t want people in Sacramento telling us how to live our lives,” grumbled one rancher.
But on the whole, there was a lot of thoughtful comment by those in attendance, and the beginnings of a dialogue between those who are charged with facilitating the wolves’ re-entry, and those who will be most affected by it. There was a focus on practical, down-to-earth matters — the threat to one’s livelihood when livestock are killed by predators, and the impracticality of maintaining 24-hour surveillance on sprawling ranch lands.

There was not much discussion of the nonlethal methods that can be used to ward off wolf depredations, although a number of speakers strongly urged that radio collars be put on wolves so ranchers can be warned if they’re getting near their cattle or sheep. That idea is already in the draft wolf management plan, as well as hazing techniques that include spotlights and air horns, as well as guard dogs and mobile electric fences.

Suzanne Asha Stone was on hand as the Rocky Mountain field representative for Defenders of Wildlife. After listening to some of the ranchers’ comments, she said, “This is verbatim what we heard in Idaho 20 years ago,” when wolves were introduced in Yellowstone National Park. Ranchers in that state were naturally concerned about the impact those wolves would have on their livelihoods. Two decades later, through programs Stone and her organization have helped implement, nonlethal strategies have reduced wolf kills of livestock in Idaho to “near zero,” she said. And that’s with a wolf population than now totals 770.

According to Stone, “It takes a while living with wolves before people realize that their worst fears won’t come true.”

I think most ranchers in California’s far north respect the wildlife around them, but their relationship with it is complicated by the need to make a living. Looking closely at the strategies used in Idaho would be a good first step in helping convince them that there are ways to reconcile ranching with the presence of this new predator.

John Wayne has long been a conservative icon, the personification of rugged individualism in the Wild West. In the 1963 movie “McLintock,” made late in his career, Wayne plays a cattle rancher and land baron. At one point he tells his daughter what he plans to do with his holdings after he dies: “I’m gonna leave most of it to the nation, really, for a park, where no lumber mill (can) cut down all the trees for houses with leaky roofs, nobody’ll kill all the beavers for hats for dudes, nor murder the buffalo for robes.”

John Wayne was no tree hugger. But neither, like the ranchers up here, should he be reduced to a simple stereotype.

ooOOoo

Back to Governments or is this case the U.S. Government and a little-known unit known as Wildlife Services. Another arm reaching out to love our wilderness? H’mmm. Not according to Wolves of Douglas County blog:

PUBLISHED FEBRUARY 12, 2016

Wildlife Services—ever heard of it? No, not the U.S. Fish and Wildlife Service. That’s something different. The Fish and Wildlife Service is part of the Department of the Interior, charged with enforcing wildlife laws, restoring habitat, and protecting fish, plants, and animals. Wildlife Services isn’t your state fish and game commission, either, which issues hunting and fishing licenses and manages local wildlife.
Wildlife Services is a federal agency under the U.S. Department of Agriculture, and it specializes  in killing wild animals that threaten livestock—especially predators such as coyotes, wolves, and cougars. Outside the ranching community, Few have heard of Wildlife Services.
Since 2000, the agency has killed at least two million mammals and 15 million birds. Although it’s main focus is predator control in the West, Wildlife Services also does things like bird control nationwide at airports to prevent crashes and feral pig control in the South.

Unexplored waters ahead!

My sub-title comes from personal knowledge of what it feels like to set out on an ocean voyage into waters that one has not sailed before. In my case, leaving Gibraltar bound for The Azores on my yacht Songbird of Kent in the Autumn of 1969.

Tradewind 33 - Songbird of Kent.
My home for five years – Tradewind 33: Songbird of Kent.

Despite me being very familiar with my boat, and with sailing in general, there was nonetheless a sense of trepidation as I headed out into a vast unfamiliar ocean.

Coming to matters closer to hand, there is a sense of trepidation felt by me and countless others as to what world we are heading into if we don’t take seriously the risks that are ‘tapping on our door’.

So hold that in your mind as you read a recent essay published by Patrice Ayme’; an essay that highlights very uncertain times ahead if we, as a global society, don’t get our act together pretty damn quick. Republished here on Learning from Dogs with Patrice’s kind permission.

Record Heat 2015, Obama Cool

2014 was the warmest year ever recorded. 2015 was even warmer, and by far, by .16 degrees centigrade. The UK (Great Britain) meteorological office announced that the temperature rise is now a full degree C above the pre-industrial average. At this annual rate of increase, we will get to two degrees within six years (as I have predicted was a strong possibility).

What’s going on? Exponentiation. Just as wealth grows faster, the greater the wealth, mechanisms causing more heat are released, the greater the heat. Yes, it could go all the way to tsunamis caused by methane hydrates explosions. This happened in the North Atlantic during the Neolithic, leaving debris of enormous tsunamis all over Scotland.

heat-2015
2015: Not Only Record Heat, But Record Acceleration Of Heat

The Neolithic settlements over what is now the bottom of the North Sea and the Franco-English Channel (then a kind of garden of Eden), probably perished the hard way, under giant waves.

Explosions of methane hydrates have started on the land, in Siberia. No tsunami, so far. But it can, and will happen, any time. The recent North Easter on the East Coast of the USA was an example of the sort of events we will see ever more of: a huge warm, moist Atlantic born air mass, lifted up by a cold front.

Notice that, at the COP 21 in Paris all parties, 195 nations, agreed to try their best to limit warming to 1.5 degree Centigrade. At the present instantaneous rate, that’s less than 4 years away. Even with maximum switching out of fossil fuels, we are, at the minimum, on a three degrees centigrade target, pretty soon.

By the way, if all nations agree, how come the “climate deniers” are still heard of so loudly? Well, plutocrats control Main Stream Media. It’s not just that they want to burn more fossil fuels (as it brings them profit, they are the most established wealth). It’s also that they want to create debates about nothing significant, thus avoiding debates about significant things, such as how much the world is controlled by Dark Pools of money.

Meanwhile, dear Paul Krugman insists in “Bernie, Hillary, Barack, and Change“, that it would be pure evil to see him as a “corrupt crook“, because he believes everything Obama says about change and all that. Says Krugman: “President Obama, in his interview with Glenn Thrush of Politico, essentially supports the Hillary Clinton theory of change over the Bernie Sanders theory:

[Says Obama]: ‘I think that what Hillary presents is a recognition that translating values into governance and delivering the goods is ultimately the job of politics, making a real-life difference to people in their day-to-day lives.’”

This is all hogwash. We are not just in a civilization crisis. We are in a biosphere crisis, unequalled in 65 million years. “Real-life differences“, under Obama, have been going down in roughly all ways. His much vaunted “Obamacare” is a big nothing. All people in the know appraise that next year, it will turn to a much worse disaster than it already is (in spite of a few improvements, “co-pays” and other enormous “deductibles” make the ironically named, Affordable Care Act, ACA, unaffordable).

The climate crisis show that there is no more day-to-day routine. At Paris, the only administration which caused problem, at the last-minute, was Obama’s. How is that, for “change”? The USA is not just “leading from behind”, but pulling in the wrong direction. Really, sit down, and think about it: under France’s admirable guidance (!), 194 countries had agreed on a legally enforceable document. Saudi Arabia agreed. The Emirates agreed. Venezuela agreed. Nigeria agreed. Russia agreed. Byelorussia agreed. China, having just made a treaty with France about climate change, actually helped France pass the treaty. Brazil agreed. Zimbabwe agreed. Mongolia agreed. And so on. But, lo and behold, on the last day, Obama did not.

I know Obama’s excuses well; they are just that, excuses. Bill Clinton used exactly the exact same excuses, 20 years ago. Obama is all for Clinton, because, thanks to Clinton, he can just repeat like a parrot what Clinton said, twenty years ago. Who need thinkers, when we have parrots, and they screech?

I sent this (and, admirably, Krugman published it!):

“No doubt Obama wants to follow the Clintons in making a great fortune, 12 months from now. What is there, not to like?

Obama’s rather insignificant activities will just be viewed, in the future, as G. W. Bush third and fourth terms. A janitor cleaning the master’s mess. Complete with colored (“bronze”) apartheid health plan.

What Sanders’ supporters are asking is to break that spiral into ever greater plutocracy (as plutocrat Bloomberg just recognized).”

Several readers approved my sobering message, yet some troll made a comment, accusing me of “racist “slander”. Racist? Yes the “bronze” plan phraseology is racist. I did not make it up. And it is also racist to make a healthcare system which is explicitly dependent upon how much one can afford. Krugman is all for it, but he is not on a “bronze” plan. Introducing apartheid in healthcare? Obama’s signature achievement. So why should we consider Obama as the greatest authority on “progressive change”? Because we are gullible? Because we cannot learn, and we cannot see? Is not that similar to accepting that Hitler was a socialist, simply because he claimed to be one, it had got to be true, and that was proven because a few million deluded characters voted for him?

We are in extreme circumstances, unheard of in 65 million years, they require extreme solutions. They do not require, nor could they stand, Bill Clinton’s Third Term (or would that be G. W. Bush’s fifth term? The mind reels through the possibilities).

“Change we can believe in”: the new boss, same as the old boss, the same exponentiation towards inequality, global warming and catastrophe, the same warm rhetoric of feel-good lies.

As it is, there is a vicious circle of disinformation between the Main Stream Media, and no change in the trajectory towards Armageddon. Yes, Obama was no change. Yes, Obama was the mountain of rhetoric, who gave birth to a mouse. Yes, we need real change, and it requires to start somewhere. And that means, not by revisiting the past.

Yes, we do need real change, and every day that we think that this change is the responsibility of someone else then that is another day lost forever. Or in the more proasic words of Mahatma Gandi, “You must be the change you wish to see in the world.”

Yes, it rains in Oregon!

Reflections on where we two Brits live.

We never planned to come and live in Southern Oregon. It was the result of a bizarre dream about our well running dry when we were living back in Payson, Arizona. Someone who was staying with us at the time, upon hearing about my strange dream, responded: “If you’re worried about water go and live in Oregon.”

So we did!

At the time of writing this post (2pm yesterday) our weather station that we have at home had recorded a total of 7.78 inches of rain for January that brought the total for December and January to 25.66 inches. Two days ago we had 2.48 inches in a single day, as these photographs bear out.

Just asas and already
Not even 11am and already 1.8 inches has fallen since midnight.

Britain before humans.

A remarkable look at the extraordinary history of the British Isles.

Now on first sight, any reasonable follower of my scribblings who lived outside Britain might wonder why this post was so focussed on one particular country, the country of my birth: Great Britain.

My justification, however, for including this George Monbiot essay is that many residents of many other countries, not just North Americans, have roots and family ties in GB. Plus, so typical of a Monbiot essay, the subject will be of interest to anyone, wherever they live in the world, who wonders about time before we shaped our environment. (I have converted some of the figures used in the essay within square brackets [ …] )

Could I also mention that from Thursday through to the end of the year, my posts in this place are going to be a mix of trivial, humorous and repeat posts. I need a bit of a break as much as you good people need a break from Learning from Dogs! 😉

Walk on the Wild Side

17th December 2015

Rewilding, hillwalking and the extraordinary history of these islands.

George Monbiot, interviewed by Dan Bailey for UKHillwalking.com, 11th December 2015

What would a natural upland habitat have looked like in Britain before humans started having the dominant influence?

This is a particularly interesting question, because we have two completely different baselines in Britain. The more recent one is the situation that prevailed after the ice retreated, and a temperate climate returned. I’m talking about parts of the Boreal and Atlantic stages, roughly between 9000 and 5000 years ago. It seems that during this period, Britain was more or less covered by closed canopy rainforest from top to toe. I’m using the term rainforest precisely: to denote forests that are wet enough to support epiphytes, plants that grow on other plants. Wherever you see polypody, the many-footed fern, growing along the branches of a tree, it’s a reminder that you are looking at rainforest fragment.

Hardly any land in this country would have been treeless at this time. With the exception of the summits of the Cairngorms, Ben Nevis and one or two other mountains, there is nowhere here that is too high for them to grow. Our bare and rocky hills are an artefact of deforestation, heavy grazing and the subsequent loss of soil.

But even that state arguably reflected the dominant influence of humans. To see what the land would have been like without them, you would have to go back to the previous interglacial period, the Eemian. At this time, the climate was almost identical to ours, but for some reason the people driven out by the previous ice age appear not to have returned to this country. At this stage, there was plenty of forest, but it seems that it was not continuous. The closed canopy rainforest was punctuated by more open forest, as well as wood pasture and savannah. Why? Because humans had not wiped out the dominant species. During the Eemian, Britain had a fairly similar collection of wildlife to the one we know today. You know: foxes, badgers, hedgehogs, deer, robins, jackdaws, elephants, rhinos, hippos, scimitar cats, hyenas and lions.

Ah yes, not the same in all respects. Like everywhere else on earth, we had a megafauna, and this shaped the ecosystem. The large herbivores were driven out of Britain by the ice, then driven to extinction in southern Europe about 30,000 years ago when modern humans arrived. (The hyenas and lions, incidentally, persisted throughout the ice age, hunting reindeer across the frozen tundra, and it seems that they survived here until about 10,000 years ago, when Mesolithic hunters turned up).

What does a typical British upland habitat look like now, and how does it differ from uplands in Mainland Europe?

In almost all other European countries (Ireland is an exception), the pattern of tree cover is what you would expect to see. The lowlands, where the land is worth farming, are largely treeless. The uplands, where the land is infertile and the climate is harsh, largely forested. This is why Europe has an average forest cover of 37%. In Britain, the lowlands are largely treeless, as you might expect, but the uplands are even barer. This peculiarity explains the fact that Britain has only 13% tree cover. Instead of a rich ecosystem in the hills, a mosaic of trees, scrub and glades (which is what would occur now, on our depleted soils, if the land were allowed to recover), the uplands are almost entirely treeless, and therefore remarkably poor in birds, insects and all the other lifeforms you might expect to find there. The parts of the country which would otherwise function as our great wildlife reserves – those places, in other words, where hardly anyone lives and there is almost no economic activity – have even less wildlife than the places that are intensely habited and farmed.

What are the people and processes responsible for keeping our hills bare in England and Wales? Who’s more to blame in Scotland?

In England and Wales, the cause is simply stated. Sheep, which originated in Mesopotamia, are wildly, disproportionately destructive. In many of our hills, they are kept at densities of no more than one per hectare or even less. But because they selectively browse out tree seedlings, they ensure that no recovery can take place. Even where remaining woods exist, they are often dying on their feet, because there are no young trees with which to replace the old ones. In terms of food production, upland sheep farming makes a minuscule contribution. It is hard to think of any industry where there is a higher ratio of destruction to production.

The denuding of our hills by sheep is supplemented by the burning of grouse moors, a fantastically destructive activity carried out for the benefit of a very small number of exceedingly rich people. These two activities ensure that in England and Wales there are scarcely any trees above around 200 m. [Ed: 656 feet]

Both are also important factors in Scotland, but in the Highlands the dominant cause of destruction is the deer stalking estates. By keeping the numbers of red deer very high, so that a banker waddling up the hillside in tweed pantaloons is almost guaranteed to make a kill, these estates have a similar effect to sheep farms. Like sheep, deer seek out the seedlings, and when their numbers rise above five or ten per square kilometre, they ensure that no forest can grow.

So why the difference between Britain and the rest of Europe? The answer seems to be the size of land holdings. Because, unlike most other European countries, Britain never had a successful revolution, we have, on one estimate, the second highest concentration of landholding in the world, after Brazil. This grants landowners inordinate power. It also leads to the situation I’ll describe in the next answer.

Where does subsidy farming come in?

People farming the uplands claimed to make their money by raising sheep. But in economic terms, sheep are ornamental. Sheep farming throughout our hills is a loss-making activity, and persists only as a result of public money, that takes the form of farm subsidies. We pay £3.6 billion [Ed: 5.33 billion US dollars] a year in this country to have our watersheds destroyed and our wildlife wiped out. The reason why the hills are kept bare here but not in the rest of Europe is that the landholdings in Britain are big enough to make subsidy harvesting a worthwhile activity: you are paid by the hectare. The more land you own, the more public money you receive. Some people take millions of pounds in these benefit payments every year. It’s extraordinary, when such restrictions are placed upon the ordinary recipients of social security, that this situation has not yet become politically explosive.

And culturally – how does our idealised view of the upland landscape feed into land management?

Our idealised, romanticised view of sheep farming, that bears almost no relationship to reality, but that is constantly drilled into our minds by programmes like Countryfile, makes it hard for us to see what is really going on. It’s because of this view that we fail to grasp a vast and obvious fact. That by denuding our hills, this economically-tiny industry has done more damage to our ecosystems and wildlife than all the building that has taken place in Britain.

Can you explain, in a nutshell, what you mean by re-wilding, and why you’d like to see it in the British hills?

Rewilding is the mass restoration of ecosystems and the re-establishment of missing species. I’m not arguing for the blanket rewilding of our hills by any means. But I believe that Britain would be greatly enriched, in terms of both wildlife and human experience, if significant areas were allowed to recover; if trees were allowed to grow in some of our denuded places, and some of the wonderful species we have lost were permitted to return. In particular, I’m thinking of beavers, boar, lynx, wolves and species that we retain in small numbers but that were once widespread, such as wildcat, pine martens, capercaillie, eagles and goshawks.

The other great benefit of allowing trees to return to the hills is the restoration of watersheds. In one study in Wales, the soil beneath woodland was found to absorb water at 67 times the rate of the soil beneath sheep pasture. The rain flashes off sheep pasture as if it were concrete, instantly causing floods downstream. Trees hold back the water and release it gradually, smoothing out the cycle of flood and drought.

Could you talk us through the stages of a habitat restoration process that could take a bare hillside and return it to woodland?

Many of our hillsides have been so thoroughly sheepwrecked that there are now no remaining seed sources. In these circumstances, we would need to plant islands of trees, using seed taken from the nearest surviving pockets of woodland in order to sustain local genetic diversity. Short of greatly reducing stocking levels or temporarily keeping herbivores off altogether, there is not a lot more that needs to be done. In some places, all that is required is temporary exclusion of grazing animals.

What is a trophic cascade, and how is this idea relevant in the British context?

A trophic cascade is an ecological process that tumbles from the top of the foodchain to the bottom. It turns out that in many places, large carnivores regulate the entire ecosystem; ecosystems that retain them behave in radically different ways to ecosystems from which they have been lost. This presents a powerful challenge to British models of conservation, as we have lost all our large carnivores here, with the result that ecological processes, and their dynamic and ever-shifting successional patterns, have been curtailed.

Critics sometimes suggest that proponents of re-wilding are advocating turning the clock back to an arbitrary point in history and then keeping things permanently fixed in this state. Is that fair?

It is precisely the opposite. Our current model of conservation fixes ecosystems at an arbitrary point and then keeps them in a state of arrested development through extreme management of the kind that everywhere else on earth we recognise as destruction, not protection: namely cutting, burning and grazing. There is no intelligible reason behind the choices that have been made by conservationists of the ecosystems and species they choose to maintain by these means. Rewilding, by contrast, has no fixed outcomes. It seeks to restore ecological processes by bringing back some of the key elements of ecosystems and the key drivers: species that trigger trophic cascades. To the greatest extent possible, it then seeks to stand back and allow natural processes to take their course.

What would a healthy population of deer look like? How about sheep – do you have a figure for environmentally supportable grazing densities?

In the infertile uplands, it is roughly 5 per square kilometre (in other words per 100 ha). [Ed: 247 acres] Beyond that point, there is almost no regeneration of trees.

The debate often seems to be framed in absolute terms – either we re-wild everywhere, and get rid of all the farmers and deer, or not at all. How big would be big enough to please you? Are you talking about re-foresting every hill, moor and mountain, from valley to summit?

The aim of the group Rewilding Britain, that I helped to found but do not run, is to allow natural ecological processes and key species to return to at least one million hectares (4.5%) of Britain’s land and 30% of our territorial waters over the next 100 years. It would like to see at least one large rewilded area to connect both land and sea – descending from the mountaintops to our coastal waters.

In somewhere as crowded as Britain are vast re-created wildernesses a viable prospect, or would it be more realistic to go for smaller scale projects in which re-wilding is just part of a mixed land use picture – projects such as Wild Ennerdale perhaps, where habitat restoration is being managed in conjunction with forestry, leisure, water extraction and livestock?

The British population is highly concentrated. Some parts of the country are exceedingly crowded; others remarkably empty. Most British uplands have a far lower population density than many parts of Europe in which wolves, lynx, bear and other species are found. Wolves have even been appearing in countries such as Belgium, the Netherlands and Denmark, where there is very little land that is unsuitable for intensive farming, and the rural population density tends to be much higher. Their arrival has been greeted by most sectors of society with delight.

Many hill-goers will recognise your picture of the degraded upland environment, but some may simply be making a different aesthetic judgement to you, valuing the barren wide open spaces for the experience they provide. If they just happen to prefer grass and heather landscape on some romantic level, and don’t much care about botany and wildlife, how might you seek to convert them?

I believe we should have both. At the moment those who value a wild, self-willed landscape have nowhere to turn in Britain. We have to travel abroad to find it and to experience magnificent encounters with wildlife. I believe this deprives us of the wonder and delight that can enhance our lives and of choice and freedom. We have nowhere in which to escape the order and control that governs all other aspects of our lives.

Hillwalkers and climbers have fought long and hard against vested landowning interests for our right to roam. There is a worry that conservation could be used to curtail these freedoms, and some evidence to support that concern. What place does public access on open upland have in a re-wilded landscape, and which would take precedence – amenity or conservation?

I was heavily involved in campaigns for the right to roam, through another group I helped to found, The Land Is Ours, and I would be dismayed by any scheme which sought to keep people out of the hills. I believe that rewilding and access are entirely compatible. While it may be necessary in some places temporarily to fence out grazing animals, the fencing required is no different from that which is already found across the uplands, and exactly the same arrangements can be made to cross it as are used today. My hope is that in some places, as a result of rewilding, in some places there will one day be no fencing at all: in other words it will mean better access than there is today.

On a related note, could public support for re-wilding have unintended consequences? Might it, for instance, be a gift to landowners and conservation bodies with priorities quite other than public access?

I would be surprised if there were no unintended consequences. But if problems arise, the policies should be modified. No good policy emerges from the egg mature and complete. It must be constantly assessed and adjusted to head off any problems that emerge.

What sort of reception have your ideas met from folk in rural communities such as hill farmers and shooting estate workers?

I think it’s fair to say that they have been mixed. There has been a fair bit of hostility from some farming and shooting groups, but also support from surprising quarters, including landowners’ representatives and a large number of individual farmers and estate owners. In the wider countryside, there is often strong support. We would do well to remember that farmers are a very small minority even of the rural population, though this often gets forgotten because of their powerful influence on policy.

Can you offer a fully thought-through transition from sheep farming and shooting to an alternative model for the rural economy, one in which rural residents still have a secure place in a re-wilded countryside? Can you understand people’s aversion to risking this?

I certainly can understand people’s concerns. But there is going to be a major transition in the countryside before long, with or without rewilding, when farm subsidies are either scrapped or greatly reduced, as they inevitably will be. When essential public services are being cut, giving €55 billion [Ed: 61 billion USD] a year from the public purse across the EU to landowners, while helping to destroy both human communities and ecological resilience is surely as unsustainable politically as it is environmentally. So what are farmers whose livelihood is sustained only as a result of farm subsidies going to do?

I have two proposals. The first is that we start campaigning for the retention of some subsidies, whose purpose would be changed to that of ecological restoration and the support of communities. Landowners and tenants would be paid to restore watersheds, woodlands, rivers and wildlife. It’s hard to see how else continued subsidies could remain publicly acceptable. Rewilding could be a way out for struggling rural communities.

The second proposal is to start investigating means by which rural people can enhance their livelihoods by enhancing the ecosystem. There are plenty of examples from around the world of eco-tourism and associated activities reviving communities by generating income and employment. Given that the traditional industries have manifestly failed to sustain jobs and incomes, in some cases it will not be hard to show the alternatives might work better. But more research is needed, and we have to remember that the same approach is not going to work everywhere. Different local circumstances demand different strategies.

“We have an incredibly narrow and restrictive vision of cultural heritage and cultural landscapes” – your words. What would a broader vision look like?

I would love to see rural culture becoming more inclusive. It’s often highly hierarchical, with the landowners and farmers sitting at the top of the pyramid, dictating policy. In some respects, democracy is a stranger to the countryside; the old, landed powers still wield disproportionate influence over the lives of others. But I don’t want to invent a new culture. I believe that democratisation and pluralism creates its own cultures, that will evolve and develop independently in different places. I’m calling on people to challenge cultural hegemony in the countryside – perhaps we could call it agricultural hegemony – and for a much wider range of voices to be heard.

Farming and shooting are supported by the current dominant countryside culture. But wouldn’t a shift to re-wilding simply be replacing this set of special interests with another, a sort of cultural colonisation of the countryside by urbanites?

That’s certainly not how I see it. And this has nothing whatever to do with the presumed urban-rural divide. Many of rewilding’s most ardent proponents live in the countryside, perhaps unsurprisingly. We are repeatedly told that the countryside is at war with the towns and vice versa. But I see no evidence of this. What I see is certain dominant interests in the countryside in conflict with other rural interests. And those dominant interests often have either one or both feet in the cities.

A few years ago there was an article in the Telegraph that sought to characterise authentic rural people. These people apparently don’t care about “newts, trees and bats”: such matters are of interest only in London. It described David Cameron as “at heart, a rural Tory”, who “still grumbles to his wife about what, for him, are ‘banned activities’ – notably shooting”. Authentic rural people, in other words, spend their adult lives in Notting Hill and drive out to their second homes for a shooting party at the weekend. People who live in the countryside and care about wildlife, on the other hand, are, “at heart”, Londoners. The rural-urban divide, as characterised in such papers, has nothing to do with location. It’s really about class.

What chance is there of significant progress being made in the current funding climate? You’ve recently written about the ‘toothless’ Environment Agency in this regard. Given the squeeze on public bodies would it be more effective to promote the out-sourcing of re-wilding to non-governmental organisations, private philanthropists and large corporate landowners such as water companies?

There is a real problem here. Government agencies are being gutted and re-centralised. Cameron’s devolution agenda is a con: he is even more of a micromanager than Tony Blair was. The current environment secretary, Liz Truss, has put her department’s head on the block, volunteering for early execution. Statutory bodies like the Environment Agency are now, in terms of what they can do, almost dead. But the crazy situation that prevails today might not – should not – last forever. It is true to say however, that we cannot rely on government alone to deliver these changes, whatever form a government might take.

Are our National Park Authorities a help or a hindrance?

At the moment, they are a real drag on progress. This is partly because of policy, such as the Lake District National Park’s application for World Heritage status, which, as currently framed, will ensure that destructive practices are locked in (and continue to contribute to flooding). And it’s partly because of the way they frame the issues. They go to great lengths to persuade us that current land management is not only compatible with the protection of nature, but actually essential to it! All their brochures and display boards and websites create the impression that these ecological disaster zones are rich and thriving ecosystems, so people are constantly misled and misdirected. They are led to believe that all is well in our national parks, that these wastelands, which are in most cases little more than sheep ranches, are magnificent wildernesses. Our national parks are a disgrace, a shame upon the nation, and park authorities with an ounce of intellectual honesty would recognise this and seek to address it.

Re-wilding seems to be moving up the agenda of the large conservation organisations, and gaining a space in the public discourse. Do you see grounds for optimism?

It certainly is. Before Feral was published, I visited all the principal conservation groups, and received responses that varied from mild interest to outright rejection. The change over the past three years has been astonishing. Rewilding appears to have moved from the fringe of the mainstream, and I’m delighted to see how these groups have begun to pick it up and engage with it. There’s still a long way to go, and plenty of daft practices still in play, but change among the conservation groups is certainly happening, albeit slowly. We will see rewilding in this country. The question is how far and how fast it will go.

ooOOoo

Much of my adopted country, the United States, is still wild and the Bureau of Land Management state that they manage “over 245 million surface acres ..”. However, to put that into perspective the area of the USA is 2.436 billion acres so the BLM managed area is just a fraction over 10%.

Finally, Monbiot refers to his book Feral. I have read it and can recommend it.

Feral-665x1024

This is much more than an issue for just Great Britain.

Our Winter Solstice.

Is the moment of publishing this post.

I thought it would make a nice change to publish tomorrow’s post a little earlier than usual. To be precise to publish it on Dec. 22, at 04:48, Coordinated Universal Time (UTC). Or in our local Pacific Standard Time (PST) UTC-8 hrs or 20:48 Dec. 21., i.e. 20:48 on the evening of the 21st December. (I am seeing the exact time being declared as 04:48 or 04:49 UTC depending on what you read.)

Granted that the Northern Hemisphere tends to deliver the worst of the Winter weather after the shortest day, it still is good to know that for the next six months, the hours of daylight, in the Northern Hemisphere, will be increasing.

My inclination to write a post on the topic was greatly influenced by a most beautiful post over on Val Boyco’s blogsite. It was called And Winter Came.  Here’s the video that Val included in her post.

Isn’t that a most beautiful few minutes!

Impossible to top that!

But I can continue including an informative item that was published over on Mother Nature News, and is republished here within the terms of MNN.

8 things to know about the winter solstice

From when it happens to why, here’s your crash course on the shortest day of the year.

By: Melissa Breyer, December 18, 2015

Hello, winter. (Photo: psynovec/Shutterstock)
Hello, winter. (Photo: psynovec/Shutterstock)

“A day without sunshine is like, you know, night,” quipped Steve Martin – and indeed, even a day with less sunshine can feel a bit dark. Our world depends on the light radiating from that big star we traipse around, and when it’s in short supply, we feel it. But if you count yourself amongst those who don’t love waking up before the sun rises and getting off work after it has set, things are about to lighten up. Hello, winter solstice!

Although winter is really just beginning, we can at least say goodbye to these short little days we’ve been suffering (and don’t let the door hit you on the way out). With that in mind, here’s a collection of curious facts to celebrate the long-awaited return to longer days.

1. There are actually two winter solstices every year


It’s sometimes easy to be hemisphere-o-centric, but the other side of the planet gets a winter solstice too. With the planet’s orbit tilted on its axis, Earth’s hemispheres swap who gets direct sun over the course of a year. Even though the Northern Hemisphere is closer to the sun during the winter, it’s the tilt away from the sun that causes cold temperatures and less light — which is when the Southern Hemisphere is toasty. So while our winter solstice is on Dec. 21 or 22, the Southern Hemisphere celebrates the same on June 21 or 22.

Here’s how that looks from space (kind of):

2. The winter solstice happens in the blink of an eye


Although the solstice is marked by a whole day on the calendar, it’s actually just the brief moment when the sun is exactly over the Tropic of Capricorn that the event occurs.

3. Which is why it happens on different days in the same year

What? Yes! In 2015, the solstice happens on Dec. 22, at 04:49 on the Coordinated Universal Time (UTC) time clock, the time standard that the world regulates its hours by. Which means any location that is at least five hours behind UTC should break out the party hats on Dec. 21. For example, in the United States the winter solstice happens on Dec. 21 at 11:49 p.m. Eastern Standard Time. The rest of the time zones can welcome longer days beginning on the 22nd.

4. It’s the first day of winter … or it’s not, depending on whom you ask

Meteorologists consider the first day of winter to be Dec. 1, but ask an astronomer — or just about anyone else — and they’ll likely answer that the winter solstice marks the start of the season. There are two ways to look at it: meteorological seasons and astronomical seasons. Meteorological seasons are based on the annual temperature cycle, explains NOAA, while astronomical seasons are based on the position of the Earth in relation to the sun.

5. It’s a time of gloriously long shadows

If you’re inclined to take pleasure in the little things, like shadows that seem cast from a funhouse mirror, then the winter solstice is the time for you. It’s now that the sun is at its lowest arc across the sky and thus, shadows from its light are at their longest. (Imagine a flashlight directly above your head and one hitting you from the side, and picture the respective shadows.) And in fact, your noontime shadow on the solstice is the longest it will be all year. Relish those long legs while you can.

6. Full solstice moons are rarer than blue ones

Since 1793, the full moon has only occurred on the winter solstice 10 times, according to the Farmer’s Almanac. The last one was in 2010, which was also a lunar eclipse! The next full moon on a winter solstice won’t be until 2094.

7. There’s a Christmas connection

Since Christ wasn’t issued a birth certificate, there’s no record of the date when he was supposed to have been born. Meanwhile, humans have been celebrating the winter solstice throughout history — the Romans had their feast of Saturnalia, early German and Nordic pagans had their yuletide celebrations. Even Stonehenge has connections to the solstice. But eventually Christian leaders, endeavoring to attract pagans to their faith, added Christian meaning to these traditional festivals. Many Christmas customs, like the Christmas tree, can be directly traced to solstice celebrations.

8. It’s a reminder to thank Copernicus

The word “solstice” comes from the Latin solstitium, meaning “point at which the sun stands still.” Since when has the sun ever moved?! Of course, before Renaissance astronomer Nicolaus Copernicus (aka “super smartypants”) came up with the ‘ol heliocentric model, we all figured that everything revolved around the Earth, sun included. Our continued use of the word “solstice” is a beautiful reminder of just how far we’ve come and provides a nice opportunity to give a tip of the hat to great thinkers who challenged the status quo.

And now go have some hot cocoa. Happy winter!

ooOOoo

Only one way to close. That is with this picture of the sun perfectly aligned with the stones at Stonehenge in Wiltshire, UK at the moment of the Winter Solstice.

The December solstice happens at the same instant for all of us, everywhere on Earth. This year the solstice occurs on Tuesday December 22nd at 04:49 GMT (Universal time) with the sun rising over Stonehenge in Wiltshire at 08:04.

Food, agriculture, and our climate.

Locavore or vegetarian? What’s the best way to reduce climate impact of food?

With Thanksgiving Day just behind us and Christmas just around the corner, this is the season of feasting.

Just last Monday I published an essay written by George Monbiot, Pregnant Silence, that highlighted the impact on our climate of modern food production. Here are a couple of paragraphs from that essay:

Freshwater life is being wiped out across the world by farm manure. In England, as I reported last week, the system designed to protect us from the tide of crap has comprehensively broken down. Dead zones now extend from many coasts, as farm sewage erases ocean life across thousands of square kilometres.

Livestock farming causes around 14% of the world’s greenhouse gas emissions: slightly more than the output of the world’s cars, lorries, buses, trains, ships and planes. If you eat soya, your emissions per unit of protein are 20 times lower than eating pork or chicken, and 150 times lower than eating beef.

Thus it seemed both timely and appropriate to republish a further essay on the topic. This one published in The Conversation by Elliott Campbell, who is Associate Professor, Environmental Engineering, at the University of California.  It is republished here under the terms of essays published in The Conversation.

Locavore or vegetarian? What’s the best way to reduce climate impact of food?

November 25, 2015

Elliott Campbell

This year’s Thanksgiving feast falls only a few days before the start of the global climate summit in Paris. Although the connections are not always obvious, the topic of food – and what you choose to eat – has a lot to do with climate change.

Our global agriculture system puts food on the table but it also puts greenhouse gases (GHG) in the air, which represent a huge portion of global emissions. GHG emissions come directly from farms such as methane from cows and nitrous oxide from fertilized fields, while other emissions come from the industries that support agriculture, such as fertilizer factories that consume fossil fuels.

Still other emissions come from natural lands, which have massive stocks of natural carbon stored in plants and soils. When natural lands are cleared to make room for more food production, the carbon in those natural pools is emitted to the atmosphere as carbon dioxide.

Adding all these emissions together makes agriculture responsible for between roughly one fifth and one third of all global anthropogenic, or man-made, greenhouse gas emissions.

How can these emissions be reduced? My own research through the University of California Global Food Initiative has focused on evaluating a wide range of factors from biofuels to local food systems.

Undoubtedly, broad emissions reductions must come from political action and industry commitments. Nevertheless, an enlightened consumer can also help achieve meaningful reductions in GHG emissions, particularly for the case of food. The trick is to understanding what food means for your personal carbon footprint and how to effectively shrink this footprint.

On par with electricity

Zooming in from the global picture on emissions to a single home reveals how important our personal food choices are for climate change. You can use carbon footprint calculators, such as the University of California CoolClimate Tool, to get an idea of how important food is in relation to choices we make about commuting, air travel, home energy use, and consumption of other goods and services.

For the average U.S. household, food consumption will be responsible for about the same GHG emissions as home electricity consumption for the average US household.

Measuring the greenhouse gas impact of different foods is complex but in general, it’s commonly agreed that plant-based diets have a lower carbon footprint. davidwoliver/flickr, CC BY-NC

That’s a significant portion of an individual’s GHG footprint but it could be seen as a blessing in disguise. While you may be stuck with your home or your vehicle for some time and their associated GHG emissions, food is something we purchase with great frequency. And every trip to the grocery store or farmer’s market is another opportunity for an action that has a significant and lasting impact on our climate.

Making concrete decisions, though, is not always straight-forward. Many consumers are faced with a perplexing array of options from organic to conventional foods, supermarkets to farmers markets, and genetically modified organisms to more traditional varieties.

And in truth, the carbon footprint of many food options is disputed in the scientific literature. Despite the need for more research, there appears to be a very clear advantage for individuals to chose a more plant-based diet. A meat-intensive diet has more than twice the emissions of a vegan diet. Reducing the quantity of meat (particularly red meat) and dairy on the table can go a long way to reducing the carbon footprint of your food.

Food miles and water recycling

Local food systems are popularly thought to reduce GHG emissions through decreased food transport or food miles. But in many cases food miles turn out to be a meaningful but small piece of the overall GHG emissions from food.

For example, a broad analysis of the US food supply suggests that food miles may be responsible for less than 10% of the GHG emissions associated with food. This general trend suggests that where you get your food from is much less important than first-order issues, such as shifting to a more plant-based diet.

A little-appreciated way of reducing the carbon footprint of food is to recycle nearby water rather than pump it long distances.

Where, then, does this leave a rapidly emerging local food movement?

For starters, there are some cases where food miles have greater importance. For example, food miles can play a big part in the carbon footprint of foods when airplanes or refrigeration are required during transport.

There is, however, untapped potential for locally produced food to deliver carbon savings around water and fertilizers.

When water is pumped long distances, it can add to food’s carbon footprint. Re-use of purified urban wastewater for irrigating crops represents one strategy for addressing this challenge but is only economically and environmentally feasible when food production is in close proximity to cities.

Using fossil fuels to produce fertilizers, such as ammonia, can also be a big piece of the carbon footprint of food. Nutrients in reclaimed wastewater and urban compost may provide a low-carbon alternative to fossil fuel-based fertilizers. But similar to water re-use, reusing nutrients is most easily done when there is a short distance between food production and consumption.

To be sure, buying local food doesn’t imply that food or nutrient recycling has happened. But developing local food systems could certainly be a first step towards exploring how to close the water and nutrient loop.

ooOOoo

I am sure many, as with me, tend not to follow through on all the links in an online essay. But there was one that really caught my eye. It was the CoolClimate Calculator on the Berkeley Edu website. It allows one to fill in a number of figures in terms of living, travel, food and more, and determine one’s total tons CO2/year emitted and how that compares with other people in your neighbourhood.  Unfortunately, it only calculates CO2/year for US locations. Does anyone know of similar calculators online in, say, the United Kingdom? Would love to know.

What nature makes up!

A suitable postscript to yesterday’s post.

Yesterday, I wrote a post under the title of You couldn’t make it up! It featured a recent essay Pregnant Silence from George Monbiot about the consequences and implications of the widespread consumption of meat and dairy products.

Now look at this example of what nature does make up.

A Sunset with Searchlights

You know those glorious fingers of sunlight that sometimes burst out from behind clouds? They’re called ‘crepuscular rays’, they form when light and shadow are rendered visible by haze in the atmosphere and these photographed by Alli Bush over Fort Collins, Colorado, US, are the Cloud of the Month for November.

The haze giving rise to crepuscular rays can be due to the air being filled with fine particles such as sand, dust or pollen. Or it can result from a delicate mist of water droplets – plentiful enough to scatter the sunlight but too scarce to show up as a cloud. The scattering is the important bit. Since we only see light that shines directly into our eyes, rays of sunlight shining in other directions are not visible unless they encounter something that scatters light towards us. Think of shining a torch beam on a clear night. The light only appears where it strikes a surface such as the ground. But on a foggy night, the full torch beam shows up because some light is also scattered towards us by the droplets of fog in the air it passes through. This is why a hazy sky renders rays of sunlight visible.

The other requisite for crepuscular rays besides haze is something to cast the shadows. Most commonly it is a cloud blocking the sunlight that creates the regions of light and shadow we see in the sky. But the crepuscular rays in Alli’s photograph are cast not by clouds but by the peaks of the Rocky Mountains. The rays fan outwards because they are coming towards the camera. In fact, the Sun’s rays are actually pretty much parallel by the time they reach Earth. They only appear to spread out like this because of the effect of perspective. It is just like looking down the length of train tracks. Even though they are parallel, they appear to spread outwards the nearer they are. Only when the sun is high in the sky so that its rays are pointing more directly downwards do crespuscular rays look parallel.

The photograph comes from the website of The Cloud Appreciation Society of which I am a lowly member. Thus it was that in my in-box yesterday was their latest newsletter. In that newsletter there was the following stunning film, described thus:

This month, we were sent an amazing film of storms over Arizona, US. It was made by Davo Laninga, Cloud Appreciation Society Member No 1,095. You can learn a lot about how storms develop by watching time-lapse videos. Well done, Davo, for this stunning example, showing the monumental power that drives our atmosphere.

Do drop in to Dave’s website and admire his incredible photographs and videos.
