Labelling and form over substance.

A providential sequel to yesterday’s post.

It was after 3pm yesterday when I turned on my computer and wondered what today’s post was going to be; I wasn’t feeling especially creative!

But sitting in my ‘in-box’ was a link to the latest newsletter from The Smithsonian and within that newsletter was a perfect sequel to yesterday’s post What’s In A Name?

I’ll go straight to that article. (Apologies if you notice that there is a fair degree of overlap between the two articles.)

Call a Dog a Pit Bull and He May Have Trouble Finding a Home

Dogs labeled as pit bulls at shelters may wait three times longer to be adopted—even when they aren’t actually pit bulls

By Rachel Nuwer, March 23, 2016

Regardless of a canine’s actual breed, simply labeling a dog a “pit bull” can condemn it to a significantly longer stay in a shelter and make it less attractive to potential adopters, concludes a new study in PLOS One.

Pit bulls are often stereotyped as aggressive and dangerous toward humans, though there is little evidence that those characteristics are inherent to the breed. The breed is popular among the dog fighting crowd, however, which contributes to its reputation for aggressiveness. To complicate matters, when attacks do occur, dogs may be labeled as pit bulls even when they are not. Indeed, in the United States, “pit bull” often serves as a catchall for a handful of breeds ranging from English bulldogs to American Staffordshire terriers; one person’s pit bull is another’s American bulldog mix.

This reputation follows the canines when they land in shelters. When potential adopters look at available dogs, they “don’t rate pit bulls any differently than look-alike dogs,” says the study’s lead author, Lisa Gunter, a graduate student in psychology at Arizona State University. “It’s only when we start attaching labels that people begin to perceive them more negatively.”

Most shelter dogs are of unknown origin, so employees often have to guess at an animal’s breed. Over a 10-year career working in shelters, Gunter noticed that she and her co-workers frequently arrived at different conclusions about a dog’s breed. And genetic studies have found significant discrepancies between descriptions of shelter dogs and their actual breed. One study found, for example, that half of the dogs that had been labeled as pit bulls at four Florida shelters had no pit bull ancestry in their DNA.

Gunter and her colleagues undertook a series of studies to find out how those potentially flawed labels might impact an animal’s chance of finding a home. They started by showing college students in California and users of the website Reddit photos of three dogs—a Labrador retriever, a pit bull-like dog and a border collie—without attached breed labels and asked questions about each, such as whether the dog looked smart or if the person would feel comfortable approaching it. The team found that participants ranked the pit bull-type dog as lowest on intelligence, friendliness, approachability and adoptability, and highest on aggressiveness and difficulty to train. When the pit bull appeared in a photo with an elderly woman or a child, however, it was rated more favorably.

Next, the researchers asked potential adopters at an Arizona shelter to rank dogs that appeared in photos and short videos on the animals’ approachability, intelligence, aggressiveness, friendliness, difficulty to train and adoptability. These scores were then summed to create an “attractiveness” composite for each pooch. To get around possible biases, such as apartment rules about animal sizes or bans on certain breeds, the team used phrases such as, “If circumstances allowed, I would consider adopting this dog,” to assess willingness to take a canine home.

These two dogs may look similar, but the pit bull label could mean that the one on the left may wait a lot longer to find a home. (Arizona Animal Welfare League)

When the dogs were not labeled as any particular breed, participants ranked pit bulls and look-alikes (dogs that were the same size and color as the pit bulls) as equally attractive. Potential adopters even ranked the pit bulls in video recordings as more attractive than the non-pit bull matches. When the researchers introduced breed labels, however, that trend reversed, with participants ranking the same dog as significantly less attractive than similar dogs without the label.

The researchers also found that pit bulls at that shelter waited over three times as long to find a home as their matched counterparts.

Finally, the team analyzed a set of data from an animal shelter in Florida that recently removed breed descriptions altogether. When freed from the loaded label, pit bull-like dogs were much more likely to find a home. Adoptions of these dogs increased by more than 70 percent, compared with the prior year, and the shelter’s euthanasia rate for the same group dropped by 12 percent, probably because more of them were finding homes.

Taken together, these results “are very convincing that breed labels negatively impact any dog that is labeled as ‘pit bull,’” says Erica Feuerbacher, who studies dogs at Carroll College in Montana and was not involved in the study. “Furthermore, we know from other studies that humans are quite bad at correctly labeling breeds, so many dogs could be erroneously labeled pit bull—even though they are not—and by that label they become less adoptable.”

Eliminating breed labels, which people seem to be using as poor proxies for stereotyped traits, may be the key to banishing a significant amount of dog discrimination—and getting more dogs into homes, Feuerbacher and the other researchers argue. There is also a need to devise better means of measuring dogs’ true personalities, including their potential for aggression, and of ensuring those assessments are valid not just in the shelter environment but also in homes, Gunter notes.

“We want to drive the adoption conversation toward evaluating whether an individual dog, regardless of the breed, is a suitable candidate for adoption,” she says. “Then we can match-make between the personality of the dog and that of the person, instead of just relying on labels.”

ooOOoo

You can see why it so perfectly followed on from yesterday!

Not just my post but yesterday’s comments. Such as this from Tony:

Another example of form over substance. When will we learn?

So I know you will all cheer Erica Feuerbacher who is quoted towards the end of that Smithsonian essay and I will close with her words, in part: “We want to drive the adoption conversation toward evaluating whether an individual dog, regardless of the breed, is a suitable candidate for adoption. Then we can match-make between the personality of the dog and that of the person, instead of just relying on labels.

Oh, and a very Happy April Fool’s Day!

What’s in a name?

“What’s in a name? That which we call a rose by any other name would smell as sweet”.

That very well-known quotation from Wm. Shakespeare was the obvious sub-title to today’s post.

You will be aware that I have written several times previously about Pit Bull dogs. But I would like to draw your attention to a post that was published here back in 2013. It was called In praise of Pit Bull dogs and featured a guest post from Noella Schink, in Portland, Maine, where she then lived and played with her 3-year-old pit bull mix, Addie, 8-year old shih-tzu, Brutus, and 2-year old hound, Lula. Apart from all of them being a little older I trust nothing else has changed.

That post in 2013 also included a picture of our gorgeous Casey, as follows.

Casey doing what dogs do so well – picking up a scent.

Over on the Care2 petition site there was a compelling case being made for Pit Bulls to be given a different name. Read it and see if you are convinced of the need.

How We Could Save More Dogs From Death Row by Changing One Thing

By: Jessica Ramos, March 29, 2016

About Jessica

Whether we like it or not, labels matter — even for dogs. New research from Arizona State University published in PLOS ONE, suggests labels could even lead to a potential death sentence, if you’re a pit bull.

Pit Bulls Wait 3 Times as Long to be Adopted

The pit bull went from America’s darling dog to one of the most feared (and misunderstood) dogs today. Their fall from grace is evident in stories like Olive’s. Olive the Pit Bull was brought in as a stray and stayed in the shelter for approximately 11 years. Olive was lucky enough to find her forever home, but so many dogs like her aren’t — and our arbitrary labels aren’t helping their cause.

According to Science Daily, researchers from Arizona State University wanted to know if breed identification influences adoption. The researchers found that dogs labeled as “pit bulls” could wait three times as long to be adopted from shelters into their forever homes compared to their lookalikes without the label or labelled as another breed.

Compared to other breeds, like Labradors, pits were perceived as less friendly and more aggressive. They also were considered less “attractive” than their lookalikes. Weird, right?

Even the researchers were surprised by how much the pit bull label influences perception and, ultimately, adoption. As researcher Lisa Gunter from Arizona State University explains, “We were surprised how very similar looking dogs sometimes get labelled ‘pit bull’ and other times as something completely different. These dogs may look and act the same, but the pit bull label damns them to a much longer wait to adoption,” reports Science Daily.

Ultimately, the researchers recommend losing the pit bull label to stop inadvertently penalizing these dogs in the shelter setting.

Heartbreaking Pit Bull Statistics

If you thought that Olive’s story was sad, she’s actually one of the lucky ones — not only for getting adopted, but for staying in the shelter system for the 11 years that she did.

According to Pit Bull Rescue Central (PBCR) 200 pit bulls are euthanized in Los Angeles County animal shelters every single day.

PBCR emphasizes that “for homeless pit bulls the death sentence is almost always automatic.”

Villalobos Rescue Center (made popular by the TV show Pit Bulls and Parolees) had this to say about the pit bull plight in Los Angeles: “The pit bull population has now risen to 40% of all the dogs in 12 shelters in Los Angeles. That means that almost half of the entire Los Angeles dog population is pits or pit mixes! Most are strays, tossed out like dirty laundry. It’s heartbreaking.”

Sadly, the plight of pit bulls is not limited to Los Angeles County. A 2013 Nat Geo Wild infographic reveals that:

  • 60 percent of the total dogs euthanized in U.S. shelters are pit bulls
  • 30 percent of the total dogs admitted to shelters are labeled pit bulls
  • 86.7 percent of pit bulls admitted to open admission shelters are euthanized

Do you know what the worst part of this sad situation is? There’s no such thing as a pit bull.

As Bark Post explains, the pit bull label is just “an umbrella term that most people use to refer to different types of dogs – the American Pit Bull Terrier, the American Staffordshire Terrier, the Staffordshire Bull Terrier, any mixes thereof, and any dog that vaguely resembles these dogs.”

The breed isn’t real, but the stigma has real consequences. And time and again pit bulls prove that they can be great dogs with the correct guidance and training when they get a second chance. Remember how Jericho the Pit Bull went from death row to being an amazing service dog?

Take Action!

Sign and share this petition urging animal rescuers to lose the stigmatizing pit bull label that unnecessarily penalizes innocent dogs. It’s a matter of life and death.

I can’t better the comment to that Care2 item left by Sheri.

Only idiots believe that pit bulls are bad! When are some morons going to finally wake up and realize bad owners are responsible for bad dogs! BSL should be banned everywhere. We must never stop fighting to end the senseless killing of this breed.

Say no more!

Caring does make a difference.

“All that evil needs to succeed is for good people to do nothing.”

You will recall that on the 8th March I published a post called Anger Alert. It was about raising awareness for “Stella has spent the last two years locked in a 3-by-9 foot cage in a kennel in Devon, England. She has never been let out to exercise or play.”

I included a link to a Care2 Petition that as of now has been signed by nearly 38,000 persons including many who read this blog. Thank you. Keep Stella in your thoughts.

Regretably, Stella’s imprisonment has not yet come to an end but here is a good news story that underlines why we must always keep fighting for the things we believe need to be changed.

Over 61,000 Care2 Activists Want To Save These Dogs From Euthanasia

3170931.large

When Kirstyn Smith heard that 31 pit bulls had been rescued from a dog-fighting ring in her native Ontario, Canada, she was thrilled, but then she learned there was a catch: Officials had plans to euthanize the dogs, rather than free them. That’s when she jumped into action and decided to create a Care2 petition.

That petition now has over 61,000 signatures, as people around the world react to the horrifying and deeply unfair death sentence.

Here’s what Smith wrote in her petition:

“My name is Kirstyn Smith and I have been following a very heart-breaking story since October 2015. The town of Chatham-Kent, ON fell victim to a horrible and cruel act where 31 pitbull-type dogs were seized from an alleged dog fighting-ring.

 These animals need our help.

Please sign and share this petition to demand that these dogs are treated humanely, medically taken care of and rehabilitated in order to live out their lives away from torture and neglect.”

Close To Victory

On March 10, she issued this update to her petition:

“We are so close! The accused have agreed to hand over ownership to Dog Tales Sanctuary in King City, ON. This is incredible news, but we still need the Ministry of Community Safety & Correctional Services to give proper designation which will allow the dogs to legally reside in Ontario. Thank you to each and every one of you for your support on this long journey!!”

Smith is referring to the fact that pit bulls are banned in the province of Ontario, and only a pound can take in pit bull-type dogs. However, Dog Tales is not a pound, so the sanctuary must make a special application in an effort to get the designation that will allow them to take in the pit bulls.

This of course is not unique to Ontario. Pit bulls are banned or restricted in most Canadian provinces; in the U.S., over 700 cities have enacted breed-specific legislation which is any ordinance, or dog law, that relates to specific dog breeds but does not affect any others.

The next court date will be March 18, and there will likely be another one after that, but things are moving forward in a positive way, thanks largely to Smith’s persistence and the awesome support of those 61,000 Care2 activists.

An Awesome Sanctuary

If justice prevails, these dogs will move to their new home, which CTV News London describes as an “opulent sanctuary in King City, Ontario, which is owned by one of Canada’s richest families.”

“The issues present are nothing that we haven’t seen before, and nothing that we feel cannot be changed with time, patience, and the proper technique,” says Clare Forndran, a spokesperson at Dog Tales Rescue and Sanctuary.

“At Dog Tales we are fortunate enough to have the facilities and the resources to provide for our dogs in ways that many other shelters cannot,” owner Danielle Eden said in an email.

While this story has come a long way and is very close to a happy ending, it’s not quite there yet.

You can help rescue these dogs from a death sentence by signing Smith’s petition, asking the authorities to treat these animals humanely, and take care of them so that they can live out their lives away from torture and neglect. 

And if you have a cause that you care deeply about, and want to make a difference in the world, you can create your own petition, just as Kirstyn Smith did. You’ll soon find the Care2 community of activists ready to join you in your cause. And if you’d like to read more about petitions, you can check out this handy guide.

ooOOoo

So, please, if you are not one of those 61,000 who have already signed this petition then, without delay, go here and add your support to this wonderful cause.

The meaning of it all!

Celebrating the life and times of Albert Einstein.

Albert-EinsteinYesterday was the centenary of the birth of Albert Einstein (14 March 1879 – 18 April 1955). It has been widely reported. For example, a piece on the EarthSky blog:

March 14, 1879. This is the anniversary of the birth of Albert Einstein, undoubtedly the most famous scientist of the modern era.

Einstein was born in Ulm, Germany, where an uncle – Jakob Einstein, an engineer – introduced him to science and math. At age 17, he enrolled in the Swiss Polytechnic Institute after failing the entrance exam the previous year. He graduated in 1900, and in 1902 he became a junior patent examiner in the Swiss Patent Office in Bern, Switzerland, where he specialized in electrical devices.

The year 1905 came to be known as Einstein’s Miracle Year. He was 26 years old, and in that year he published four papers that reshaped physics.

Now before you read on let me proclaim that today’s post has absolutely nothing to do with dogs! (Unless dogs exist in parallel universes!)

But a recent documentary that was published on Top Documentary Films was really fascinating and incredibly well presented. Thus, in terms of the likes of you and I better understanding what Einstein revealed about our universe, I couldn’t resist sharing it with you all today. It is just 29 minutes long.

STORYLINE

One hundred years have passed since Albert Einstein first unleashed his highly influential Theory of General Relativity unto the world. These revelations charted a future course of scientific pursuit, and never cease to inform our understanding of the universe today. In celebration of that impressive legacy, the documentary short Einstein’s Extraordinary Universe travels to three research facilities in different regions across the globe, and shows us how Einstein’s work continues to challenge, shape and inspire the scientific discoveries of tomorrow.

The film opens in Tuscany. Under the shadows of Galileo’s groundbreaking work on gravity research, a group of astrophysicists are exploring Einstein’s theories related to the occurrence of gravitational waves through space and time. Can modern technologies and advanced scientific intellect result in actual proof of such waves?

Viewers are then taken to the world’s largest underground laboratory. Hidden far beneath Italy’s Gran Sasso mountains, the lab serves as a home to researchers who work tirelessly to prove another of Einstein’s grandiose theories: the existence of dark matter. The vast majority of our universe is made up of materials that we have not yet been able to detect through forces of light and energy. The dedicated team who toil away in this impressive underground lair hope they can lay the groundwork in changing that.

The filmmakers’ next stop is Switzerland, where they are given a tour of one of the most impressive displays of scientific testing technology on the planet. Housed by the European Organization for Nuclear Research, or CERN, the Large Hadron Collider is the most powerful particle accelerator on the planet, and is being used to question and examine the substance of all matter in our universe.

Through each destination on this incredible journey, what amazes most is how prescient Einstein’s theories have proven even after a century has passed. His work continues to test the limits of our scientific understanding, and sets a groundwork from which researchers still strive for answers. Featuring a plethora of illuminating interviews with many top figures in the fields of scientific study, Einstein’s Extraordinary Universe is certain to delight seasoned science geeks and novices alike.

What an extraordinary mind he had!

Continuing the stark assessment of where we are today.

In yesterday’s post I covered the first five of the eleven facts about sea-level rise. Here are the rest of those facts.

11 alarming facts about sea-level rise

Russell McLendon, February 26, 2016.

6. Sea levels could rise another 1.3 meters (4.3 feet) in the next 80 years.

In another study published this month, scientists report that global sea levels will likely rise 0.5 to 1.3 meters (1.6 to 4.3 feet) by the end of this century if greenhouse gas emissions aren’t rapidly reduced. Even if last year’s Paris Agreement does spur ambitious climate policy, sea levels are still projected to rise 20 to 60 cm (7.8 to 23.6 inches) by 2100. Taken with the longer-term effects from melting ice sheets in Greenland and Antarctica, that means any strategy to endure sea-level rise must involve adaptation plans as well as efforts to slow the trend.

7. Up to 216 million people currently live on land that will be below sea level or regular flood levels by 2100.

Of the estimated 147 million to 216 million people in harm’s way, between 41 million and 63 million live in China. Twelve nations have more than 10 million people living on land at risk from sea-level rise, including China as well as India, Bangladesh, Vietnam, Indonesia and Japan. Bangladesh is especially vulnerable, identified by the U.N. as the country most in danger from rising seas. Once the ocean rises by 1.5 meters (4.9 feet) next century, it will affect 16 percent of Bangladesh’s land area and 15 percent of its population — that’s 22,000 km2 (8,500 mi2) and 17 million people.

The situation is also urgent for low-lying island nations like Kiribati, the Maldives, the Marshall Islands and the Solomon Islands, where land is already so close to sea level that a few inches make a world of difference. Some are even mulling mass relocations — the government of Kiribati, for one, has a web page outlining its strategy for “migration with dignity.” A town on Taro Island, the capital of Choiseul Province in the Solomon Islands, is also planning to move its entire population in response to rising seas. The small community of Newtok, Alaska, has already begun the difficult process of transplanting itself away from the encroaching coast.

8. Sea-level rise can contaminate water used for drinking and irrigation.

In addition to surface flooding, sea-level rise can both push up the freshwater table and contaminate it with seawater, a phenomenon known as saltwater intrusion. Many coastal areas rely on aquifers for drinking water and irrigation, and once they’re tainted by saltwater they may be unsafe for humans as well as crops.

It is possible to remove salt from water, but the process is complex and costly. San Diego County recently opened the Western Hemisphere’s largest desalination plant, for example, and several other sites are proposed in the state. Yet that may not be practical for many coastal communities, especially in less wealthy nations.

9. It can also threaten coastal plant and animal life.

Humans aren’t the only ones who’ll suffer as sea levels rise. Any coastal plants or animals that can’t quickly move to new, less flood-prone habitats could face dire consequences. As one 2015 study noted, sea turtles have a long-established habit of laying eggs on beaches, which need to stay relatively dry for their babies to hatch.

Inundation for one to three hours reduced egg viability by less than 10 percent, the study’s authors found, but six hours underwater cut viability by about 30 percent. “All embryonic developmental stages were vulnerable to mortality from saltwater inundation,” the researchers write. Even for hatchlings that do survive, being starved of oxygen in the egg could lead to developmental problems later in life, they add.

Other beach life may also be at risk, including plants. A recent study found that some salt marshes can adapt, both by growing vertically and by moving inland, but not all flora will be so fortunate. “Trees have to work harder to pull water out of salty soil; as a result, their growth can be stunted — and if the soil is salty enough, they will die, a common sign of sea-level rise,” Climate Central explains. “Even trees that are especially suited to salty soil can’t survive repeated flooding by seawater.”

10. Global flood damage for large coastal cities could cost $1 trillion a year if cities don’t take steps to adapt.

The average global losses from flooding in 2005 were about $6 billion, but the World Bank estimates they’ll rise to $52 billion per year by 2050 based on socioeconomic changes alone. (That means things like increasing coastal populations and property value). If you add the effects of sea-level rise and sinking land — which is happening even faster in some places — the cost could surge to $1 trillion per year.

11. It’s too late to stop sea-level rise — but not too late to save lives from it.

Unfortunately, CO2 emissions linger in the atmosphere for centuries, and today’s CO2 levels have already committed Earth to dangerous sea-level rise. About 99 percent of all freshwater ice resides in two ice sheets: one in Antarctica and one in Greenland. Both are expected to melt if humanity’s CO2 output isn’t curbed quickly, but the question is when — and how much damage we still have time to prevent.

The Greenland ice sheet is smaller and melting more quickly. If it completely melted, sea levels would rise by about 6 meters (20 feet). The Antarctic ice sheet has been more buffered from warming so far, but it’s hardly immune, and would raise the ocean by 60 meters (200 feet) if it melted. (Estimates vary widely on how long these ice sheets might survive — while most expect they’ll take centuries or millennia to melt, a controversial 2015 paper suggested it could happen much more quickly.)

Sea levels have naturally risen and receded for billions of years, but they’ve never risen this quickly in modern history — and they’ve never had so much human help. It’s unclear what effect they’ll have on our species, but what is clear is that our descendants will still be dealing with this problem long after we’re all gone. Giving them a head start on a solution is the least we can do.

“With all the greenhouse gases we already emitted, we cannot stop the seas from rising altogether, but we can substantially limit the rate of the rise by ending the use of fossil fuels,” says Anders Levermann, a climate scientist at Columbia University and co-author of the new study on future sea-level rise. “We try to give coastal planners what they need for adaptation planning, be it building dikes, designing insurance schemes for flooding or mapping long-term settlement retreat.”

As another recent study pointed out, any policy decisions made in the next few years and decades “will have profound impacts on global climate, ecosystems and human societies — not just for this century, but for the next ten millennia and beyond.”

Tomorrow, in the final part of this three-part posting I will look at some positive things that we can all be doing now.

But let me leave you with a rather beautiful consequence of these changing times. As seen over on Grist:

The beat of a butterfly’s wings.

From Wikipedia:

The Butterfly Effect is a concept that small causes can have large effects. Initially, it was used with weather prediction but later the term became a metaphor used in and out of science.[1]

In chaos theory, the butterfly effect is the sensitive dependence on initial conditions in which a small change in one state of a deterministic nonlinear system can result in large differences in a later state. The name, coined by Edward Lorenz for the effect which had been known long before, is derived from the metaphorical example of the details of a hurricane (exact time of formation, exact path taken) being influenced by minor perturbations such as the flapping of the wings of a distant butterfly several weeks earlier. Lorenz discovered the effect when he observed that runs of his weather model with initial condition data that was rounded in a seemingly inconsequential manner would fail to reproduce the results of runs with the unrounded initial condition data. A very small change in initial conditions had created a significantly different outcome.

We all live in an interconnected world. Frankly, it’s such an obvious statement that one presumes that very few would not agree with the sentiment expressed within it.

But (and you knew there was a ‘but’ coming, didn’t you!) very few of us (and I include Jean and me to a very great extent) really understand, “A very small change in initial conditions had created a significantly different outcome.”

Take these few items; more or less randomly read over the last few days.

Such as this post over on Patrice Ayme’s blog.

Biblical Flood Starting Anew

Abstract: update on Sea Level Rise. The meat of the essay is at the end, in the section “THE SITUATION IS ACTUALLY CATACLYSMIC“.

Heard of The Flood? As in the Bible? Sea level rose 120 meters (400 feet), in the period centered around 10,000 years ago. The cause? More than half of Earth’s ice melted in a few millennia,  During the rest of the early Holocene, the rate of rise of the world’s ocean reached peaks as high as 60  millimeters (2.5 inches) per year. The melting of the ice happened because Earth’s positional and orbital parameters had made northern hemisphere’s summers too warm (most of the ice shields rested on the large continents of the north). Nowadays only two enormous ice shields are left: Greenland and Antarctica.

Those who enjoy catastrophes will love it: we have 75 meters of further sea rise to enjoy pretty soon, on our way to a Jurassic climate (the Jurassic was characterized by gigantic warm shallow seas on top of the continents). Here was the situation in the Miocene, when CO2 was at 500 ppm (where we will be at in ten years, see conclusion below).

Patrice said that the essence, the meat, of his essay was at the end. Here are his closing words:

Three scientific papers published in the last two months support my, admittedly drastic, point of view. One observed the collapse of a colossal glacier in northwest Greenland, eaten by a current at one degree C. It was a miniature reproduction of what to expect for entire ice shields. Two others observed the past, and that Antarctica was unstable at 500 ppm CO2. What they did not say is how dramatic the situation was. Indeed, sounding moderate is how they get funded by a benevolent, plutocratically ruled government (and by government, I also mean the corrupt Supreme Court, not just the latest elected buffoons). The scientists who evoked the 500 ppm of CO2 omitted two significant details, where the devil lurks. They claimed that it would take 30 years to get there. That’s not correct; at the present rate, we will add 100 ppm of CO2 within 25 years. But not just that: there are other man-made GreenHouse Gases (GHG): CH4, NOx, Fluorocarbons, etc. All these gases warm up the lower atmosphere much more than CO2. So the correct measurement is not CO2 ppm, but CO2 EQUIVALENT ppm.

We are right now ABOVE 450 ppm in EQUIVALENT CO2, and will be at 500 ppm within ten years. Let’s hope there will be more boats than on the Titanic.

Patrice Ayme’

P/S: If anything, the preceding is a conservative estimate. Indeed very serious scientists evaluated already the man-made greenhouse gases at 478 ppm in 2013. This means we will be above 500 ppm in CO2 equivalent within six years, in line with my previous analyses, such as “Ten Years To Catastrophe“. See:

http://oceans.mit.edu/news/featured-stories/5-questions-mits-ron-prinn-400-ppm-threshold

Now it’s not all ‘doom and gloom’ and there is much that each and every one of us can do. More of that in Interconnections Three on Thursday.

But to continue with this ‘wake up call’ I’m going to republish in full an item that was recently published over on Mother Nature Network: 11 alarming facts about sea-level rise. To stop today’s post being excessively long, I’m going to split that MNN article over today and tomorrow. Here are the first 5 alarming facts. (Don’t read them just before turning the light out when going to bed tonight!)

The ocean is coming for us. Global sea levels are now rising by 3.4 millimeters per year, up from an average rate of 1.4 mm per year last century. In just 80 years, the ocean could be a full 1.3 meters (4.3 feet) taller than it is today.

That kind of planetary sea change can be hard to fathom — unless you live in a low-lying place like Miami, the Maldives or the Marshall Islands, where the effects of sea-level rise are already apparent. But within just a few decades, the problem will become unavoidable in major coastal cities around the world, from New Orleans, New York and Amsterdam to Calcutta, Bangkok and Tokyo.

We all know why this is happening. Rising seas are one of the most salient effects of man-made climate change, triggered by thermal expansion of seawater as well as the influx of melting glaciers. Yet many people still see it as a distant risk, failing to grasp how (relatively) quickly the sea is swallowing shores worldwide. And since half of all humans now live within 60 kilometers (37 miles) of a coast, this isn’t a niche issue.

To help put things in perspective, here’s a deeper look at the problem:

1. Global sea levels have already risen by 8 inches (200 mm) since 1880.

sea-level-rise-1880-2014

The chart above was produced by NASA’s Earth Observatory, based on data from the U.S. National Oceanic and Atmospheric Administration (NOAA) and Australia’s Commonwealth Scientific and Industrial Research Organization (CSIRO). Most of those historical data come from tide-gauge measurements, which are now complemented by satellite observations.

2. Not only are sea levels rising; the rate of their rise is rising.

On average, sea levels rose by 1.4 mm from 1900 to 2000. The yearly pace had surpassed 3 mm by 2010, and now it’s up to 3.4 mm per year.

3. That’s the fastest sea-level rise Earth has experienced in 3,000 years.

Cb5MxZ4WIAAAW06If not for surging carbon dioxide in the atmosphere, sea levels should have only risen about an inch or two last century, and might have even fallen. Instead, thanks to the highest CO2 levels at any point in human history, global sea levels rose by 5.5 inches (14 cm) between 1900 and 2000. That’s the fastest oceanic advance in 27 centuries, according to a study published Feb. 22, and it’s still speeding up.

“The 20th century rise was extraordinary in the context of the last three millennia — and the rise over the last two decades has been even faster,” says lead author Robert Kopp, a climate scientist at Rutgers University, in a statement.

“Scenarios of future rise depend upon our understanding of the response of sea level to climate changes,” adds co-author Benjamin Horton. “Accurate estimates of sea-level variability during the past 3,000 years provide a context for such projections.”

4. Every vertical inch of sea-level rise moves the ocean 50 to 100 inches inland.

5. That’s already causing flood problems in many big coastal cities.

As the ocean invades coastal cities, the first signs of trouble are often urban saltwater floods. These can also happen naturally, though, so to determine the influence of rising seas, a new report by Climate Central models “alternative histories simulating the absence of anthropogenic climate change” at 27 U.S. tide gauges.

Out of 8,726 days since 1950 when unaltered water levels exceeded the National Weather Service thresholds for local “nuisance” floods, 5,809 didn’t exceed those thresholds in the alternative histories. “In other words,” the report explains, “human-caused global sea level rise effectively tipped the balance, pushing high-water events over the threshold, for about two-thirds of the observed flood days.”

Coastal flooding days have more than doubled in the U.S. since the 1980s, according to the report, in places ranging from Miami, Virginia Beach and New York to San Francisco, Seattle and Honolulu. According to a 2014 report, at least 180 floods will strike Annapolis, Maryland, during high tides every year by 2030 — sometimes twice a day. The same will be true for about a dozen other U.S. cities by 2045, not to mention many other low-lying urban areas around the world.

Make a leap!

This seemed a rather appropriate post for today, February 29th.

Leap day: fixing the faults in our stars

The number 2016 divided by 4 equals 504, exactly – with no remainder, which makes the year 2016, like the upcoming years 2020, 2024 and 2028 (and beyond), a leap year. We will get an “extra” day, February 29.

This pattern will repeat until 2100, when the cycle breaks. Though 2100 is exactly divisible by 4, there is an exception – for years whose number is exactly divisible by 100. (On top of that, there’s another exception – for years exactly divisible by 400. So 2400 will be a leap year. Mark your calendars now.)

Where do these quadrennial liberties with our calendar originate?

In the stars, of course.

Celestial rhythms

One of the simplest joys of life is to watch the stars, night after night, month after month, year after year. They become old friends. They spend a season, and then move on. Or rather, it is we who move on – ever advancing around the sun toward next week’s deadlines, new constellations, new fashions and new ideas.

Orion, the annual visitor. Mouser, CC BY-SA

I imagine myself late one night, eight months from now, remembering the overfull recycling bin, at midnight on trash day. As I try to quietly dump wine bottles into the yellow-topped container, there striding over the eastern skyline is Orion. Back again is my ancient friend, telling me that winter is near, and that I have ridden this miraculous rock almost another full lap around my home star. Rigel shimmers its blue-white light, the twinkle in the eye (the knee, actually) of a companion who has visited me, annually, every place on Earth I have lived since childhood. Even to the Southern Hemisphere, the steady Orion came for a summer visit – cartwheeling upside down, feet over hands.

It is from these celestial cycles that our concepts of time originate, and, ultimately, from which we gain the leap day.

The sidereal year is the length of time it takes for the Earth to return to the same place with respect to the “fix’d” and “constant” stars, so that Orion appears exactly in the same place in the sky, at exactly midnight, 365.2563 days later. Stellar friends like that don’t stand you up; they keep their appointments to seven-digit precision (and more).

Our Western calendar is tied to the tropical year – the time between successive vernal equinoxes. At that moment, the sun’s position in the sky is exactly where the ecliptic (the plane of the solar system and the path that the planets take as they move through the constellations) crosses the celestial equator (the projection of the Earth’s own equator onto the celestial sphere). Straddling the celestial equator, the sun splits its time exactly between the day side and the night side of the Earth. It returns to that place again in roughly 365.24219 days. Roughly.

Now you can see where those alternating “divisible by 4, 100 and 400” leap year rules originate.

Making up the differences

At the end of 365 days, there are still 0.24219 days (just shy of six hours) to go before Earth gets back to the equinox line.

After four years, however, this fractional 0.24219 of a day adds up to 0.96876, which is pretty close to one full day. If we were using only a 365-day calendar, the stars, and more importantly the months, corresponding to the seasons – crucial for agricultural societies – would slip behind. This was apparent to the Romans in the first century, as well as to the Olmecs and the Maya on the other side of the world.

Thus decreed Julius Caesar in 46 B.C.: that every four years an extra day would be added to February. It was called the Julian calendar. But adding one day every four years, in order to make up for that 0.96876 of a day in orbital spare change, is overcompensating. Caesar’s “every four” leap year prescription adds 0.03124 of a day too much. This makes the Julian calendar run fast by just over 600 seconds per year.

Exception after exception: Christopher Clavius, in a line engraving by E de Boulonois. Wellcome Trust, CC BY

Like with the spare coin jar in our house, small change like that takes a while to add up. It wasn’t until the age of Pope Gregory XIII, in 1582, that this mismatch was becoming a problem. After consultation, presumably with God, but particularly with his astronomer, Christopher Clavius, the pope adopted Clavius’ clever solution.

The Julian calendar runs fast by 0.03124 of a day every four years; multiply both sides by 100, and see an excess of about three days after 400 years. Clavius’ solution was to make centuries exceptions – but that would lose too much, four days in 400 years, not three. So Clavius added one back, once every 400 years, starting in 1600.

This Gregorian calendar, which we use today, has the following rules:

  • Every year divisible by 4: add February 29
  • Every century (1800, 1900, 2000, 2100): do not add February 29
  • Every century divisible by 400: add February 29

Still finer measurements

Even with this refinement, there is still orbital change left over. But now we are talking about temporal shavings that are quite small. At this level of precision, other wobbles in the relation of the Earth’s rotational period (the day) and its revolution period (the year) have to be taken into account.

When a leap second is added, digital clocks tick past 23:59:59 but don’t go directly to 00:00:00. Twid

Keeping track of minute effects like this is the job of the International Earth Rotation and Reference Systems Service, which controls the addition (or deletion) of leap seconds. For example, a second was added to Coordinated Universal Time by the service on June 30, 2015, due largely to the slowing of the Earth’s rotation by the gravitational pull of the moon.

There are other sources of calendar slip: the 8.9 magnitude earthquake that triggered the Japanese tsunami on March 11, 2011, for example, shifted the planet’s mass distribution enough to decrease the length of a day by 1.8 microseconds. This will add up to about a second after 1,500 years.

Using that ‘extra’ time

Personally, I think we should make February 29, leap day, a global holiday. It should be considered a gift to ourselves, like taking that accumulated spare change to the grocery store coin-counting machine, and trading it for some easier-to-spend bills. It should be a day of celebration, a reward for saving that quarter of a day over the last four years, to be spent on something frivolous. Or it could be a special day to realign our sense of hourly routines, weekly trash pickups, the race to fulfill monthly quotas, to the celestial schedule.

Without that extra day every fourth year, our ancient friends would begin to miss their annual appointments, and start to fall behind in wishing us prompt birthday greetings, like forgetful Facebook friends. Without February 29, roughly, every four years, the “constant stars” would cease to be constant.

ooOOoo

So there! Now you know!

You all spend this extra day peacefully and happily.

Personal journeys

Life is a one-way track.

Those of you who follow this place on a regular basis know that last Friday I published a post under the title of Friday Fondness. You will also know that later that same day I left this comment to that post:

Sue, and everyone else, we returned from seeing Dr. Lee, the neurologist, a little under two hours ago. Dr. Lee’s prognosis is that Jean is showing the very early signs of Parkinson’s disease, and Jean is comfortable with me mentioning this.

Everyone’s love and affection has meant more than you can imagine. I will write more about this next week once we have given the situation a few ‘coatings of thought’.

Jean sends her love to you all!

Thus, as heralded, I am going to write some more.

You would not be surprised to hear that the last few days have been an emotional roller-coaster, for both Jean and me. Including on Monday Jean hearing from our local doctor here in Grants Pass, OR, that a recent urine test has shown that Jean has levels of lead in her bones some three times greater than the recommended maximum. While our doctor is remaining open-minded it remains to be seen whether Jean is exhibiting symptoms of lead poisoning, whether the lead is a possible cause of the Parkinson’s disease (PD), see this paper, or whether it is a separate issue to be dealt with.

However, I want to offer some more from the consultation that Jean had with the neurologist Dr. Eric Lee last Friday. Shared with the full support of Jean who has read the whole of today’s post yesterday evening; as she does with every post published in this place.

But before so doing, please understand that while I was present throughout the complete examination of Jean, what you are about to read carries no more weight than that of any casual onlooker. If you are at all affected by any of the following make an appointment to see your own doctor!

Jean’s examination lasted for about an hour. It consisted of a great number of checks and tests on how her body responded to many different tests and stimulations. At the end of the examination Dr. Lee said that while he wasn’t 100% certain the balance of probability was that Jean was demonstrating the very early signs of PD. For example, showing such signs as walking and not swinging both arms in a normal, balanced manner. Or having a very slow blink rate. Then she was exhibiting some difficulty with rapid finger-to-thumb taps.

However, Dr. Lee did say that Jean was at the very early stages of PD and that we would have to wait another six months to see if the PD indicators were firming up. He also said that he had PD patients who had had the disease for twenty, even thirty years. Some of the general indicators that PD is progressing include a stooped gait, decreasing size of handwriting, and a quieter speaking tone. The NINDS website has more information on this. Here’s a little of what they explain about PD:

What is Parkinson’s Disease?

Parkinson’s disease (PD) belongs to a group of conditions called motor system disorders, which are the result of the loss of dopamine-producing brain cells. The four primary symptoms of PD are tremor, or trembling in hands, arms, legs, jaw, and face; rigidity, or stiffness of the limbs and trunk; bradykinesia, or slowness of movement; and postural instability, or impaired balance and coordination. As these symptoms become more pronounced, patients may have difficulty walking, talking, or completing other simple tasks. PD usually affects people over the age of 60.  Early symptoms of PD are subtle and occur gradually.  In some people the disease progresses more quickly than in others.  As the disease progresses, the shaking, or tremor, which affects the majority of people with PD may begin to interfere with daily activities.  Other symptoms may include depression and other emotional changes; difficulty in swallowing, chewing, and speaking; urinary problems or constipation; skin problems; and sleep disruptions.  There are currently no blood or laboratory tests that have been proven to help in diagnosing sporadic PD.  Therefore the diagnosis is based on medical history and a neurological examination.  The disease can be difficult to diagnose accurately.   Doctors may sometimes request brain scans or laboratory tests in order to rule out other diseases.

But here’s the good news regarding my darling wife – there are three things that Dr. Lee strongly recommends:

  1. Hang on to a positive mental attitude for the body actively produces dopamine when in a positive mental state.
  2. At least 30-minutes of good aerobic exercise three times a week,
  3. And physiotherapy.

In addition, Dr. Lee said to always THINK BIG! Big in voice, big in attitude, big in stature.

Finally, let me share with you what was posted on the Visible Procrastinations blog back in 2009. Reposted with the author’s permission.

My Change Journey

Some notes from My Change Journey: This workshop is designed to help you understand your emotional and psychological needs during times of change and strategies you can use to take control of your own change journey. It also focuses on creating opportunities and seeing possibilities in the new world of work.

change – an event that occurs when something passes from one state or phase to another;

transition – the act of passing from one state or place to the next

The Big Picture

You are not always seeing the bigger picture;

Experiencing Transitions

When change is implemented at any level in an organisation, people typically respond by moving through a series of phases. People will spend different times in each phase.
Bridges (1995)
William Bridges (1995) Bridges’ three-phase transition framework: The first phase, the Ending phase, is about letting go of an old identity, an old reality or an old strategy. The Neutral Zone is akin to crossing the wilderness between the old way and the new. The final phase is making a new beginning and functioning effectively in a new way.

The Process of Transition

John Fisher’s model of personal change – The Transition Curve – is an excellent analysis of how individuals deal with personal change.

You should only worry about things that are within your sphere of influence.

From The Seven Habits of Highly Effective People – you should only worry about things in your “sphere of influence.” If you have no control over certain aspects of your life, why bother worrying about them?

Mental Models: our way of seeing the world

Mental models are usually tacit, existing below the level of awareness – they should be tested, examined and evaluated.

Joel Barker pioneered the concept of paradigm shifts to explain profound change and the importance of vision to drive change within organizations. View The Power of Paradigms [SWF].

Take 1000
add 40 to it
Now add another 1000
Now add 30
Add another 1000
Now add 20
Now add another 1000
Now add 10
What is the total?

Did you get 5000 ? The correct answer is actually 4100 .

LearningFromDogs_3DBook_500x

Let me close today’s post with the opening and closing paragraphs from Chapter 25 of my book: A Way into Our Own Soul.

“Happiness resides not in possessions, and not in gold, happiness dwells in the soul.”

So wrote the philosopher Democritus who was born in 460 BCE (although some claim his year of birth was 490 BCE). He acquired fame with his knowledge of the natural phenomena that existed in those times and history writes that he preferred a contemplative life to an active life, spending much of his life in solitude. The fact that he lived to beyond 100 suggests his philosophy didn’t do him any harm.

………..

In humans, that part of the brain in which self-awareness is thought to arise is called the ventromedial prefrontal cortex. Apparently, that just happens to be located behind the eyes. Ergo, we learn[1] to associate the identity of others with our eyes. Then as we mature, our eyes take on more importance because we develop awareness and a better understanding of the social cues that other people convey with their eyes.
Therefore, is it any surprise that dogs, being the intuitive creatures that they are, soon learn to read us humans and the feelings and emotions that we transmit from our eyes? There’s a knowing in my mind, albeit an unscientific knowing, that dogs, too, give out emotions and feelings from their own eyes.

That loving a dog and being loved back by that dog truly does offer us a way into our own souls. No better put than in the exquisite words of Anatole France,

Until one has loved an animal, a part of one’s soul remains unawakened.

Oh, and a postscript. Having a loving contact with another person or your dog also releases dopamine within the body – so go and hug your partner or your dog! Now! 🙂

The core relationship; with ourself.

A reposting of an item from this place some three years ago.

On Sunday, in recognition of Valentine’s Day, I posted a selection of articles under the post title of Loving Relationships.

Then yesterday my day that should have been quiet and uneventful turned out to be anything other than that! So it was well after 3pm that I sat down in front of my PC wondering what to publish today. I thought that as there had been a steady flow of new readers signing up to follow this place (and a huge thank you – it really does mean a lot to me) I might see what I published three years ago.

To my surprise it was a post about the most important relationship of all; the one with ourself.

So please do enjoy what was published on February 15th, 2012.

Do you or I really know who we are?

The strangeness of this species Homo sapiens.

My writings of the previous three days have explored the nature of man. The many ways that we struggle to understand so many issues in our lives. In particular the biggest issue of them all since we abandoned the life of the hunter-gatherer. Our very survival.

It would be so easy to beat oneself up. To stare in the mirror and despair at all the unfinished ideas that one has about being ‘sustainable’ shortly before jumping on one’s shiny new tractor, yet another symbol of our industrial civilisation. The hypocrisy, the double standards!

New tractor being delivered last December.

But the mistake in any attempt at self-awareness is the assumption that you know who you are! Therein lays the problem.!

Marcus Peter Francis du Sautoy is a very smart person. This is how WikiPedia describes him.

sautoy
Prof. Marcus Sautoy

Marcus Peter Francis du Sautoy, OBE (born in London, 26 August 1965)[3] is the Simonyi Professor for the Public Understanding of Science and a Professor of Mathematics at the University of Oxford. Formerly a Fellow of All Souls College, and Wadham College, he is now a Fellow of New College. He is President of the Mathematical Association.

Prof. Sautoy came to the realisation that the thoughts that make us feel as though we know ourselves are easy to experience. But where do those thoughts come from? Marcus Sautoy acknowledged that they are notoriously difficult to explain.

So, in order to find out where they come from Marcus subjects himself to a series of probing experiments. With the help of a hammer-wielding scientist, Jennifer Aniston and a general anaesthetic, Professor Marcus du Sautoy goes in search of answers to one of science’s greatest mysteries: how do we know who we are?

He learns at what age our self-awareness emerges and whether other species share this trait.

Next, he has his mind scrambled by a cutting-edge experiment in anaesthesia. Having survived that ordeal, Marcus is given an out-of-body experience in a bid to locate his true self. And in Hollywood, he learns how celebrities are helping scientists understand the microscopic activities of our brain.

Finally, he takes part in a mind-reading experiment that both helps explain and radically alters his understanding of who he is.

All of this is covered in a fabulously interesting episode from Horizon, the excellent and long-running BBC TV science and philosophy series. Thankfully, it made its way onto YouTube.

(NB: In the intervening period, that BBC Horizon programme has been removed from YouTube for copyright reasons. That’s a great shame. However, the following documentary from the good Professor will, I am sure, be equally fascinating.)

The Secret Rules of Modern Living Algorithms

Published on Oct 30, 2015

Without us noticing, modern life has been taken over. Algorithms run everything from search engines on the internet to satnavs and credit card data security – they even help us travel the world, find love and save lives.
Mathematician Professor Marcus du Sautoy demystifies the hidden world of algorithms. By showing us some of the algorithms most essential to our lives, he reveals where these 2,000-year-old problem solvers came from, how they work, what they have achieved and how they are now so advanced they can even programme themselves.

As Confucius reportedly wrote: Real knowledge is to know the extent of one’s ignorance.
