Doggedly seeking the truth.

As a dog follows a scent.

P1110019
Casey doing what dogs do so well – picking up a scent.

I have been pondering about how one gets to the truth of a complex issue.  And there’s none more complex nor more essential in terms of the truth of an issue than Anthropogenic Global Warming (AGW).

It was kicked off by an email received from Dan Gomez.  Followers of Learning from Dogs will have seen mention of Dan’s name as he regularly sends me bits and pieces.  Indeed, let me refer you to a post that came out last August, Feeling depressed? Join your pals in the pool! and this extract:

Regular followers of Learning from Dogs will know that Dan and I go back a long way; far too long! In fact the occasion of me becoming aware of Mr. Daniel Gomez was at a Commodore Computer dealers conference in Boston, Mass.

I was giving a talk promoting a UK word-processing program that I was marketing for the Commodore. That software was called Wordcraft and I think the year was 1979, possibly 1980. Anyway, I used the word ‘fortnight’, which back in England is a common word meaning two weeks. Immediately, a voice called out from the audience, “Hey Handover, what’s a fortnight?“

The session deteriorated rapidly thereafter! Dan and I became very good friends and his LA company Cimarron became my West Coast USA distributor for Wordcraft. And it was Dan’s sister, Suzann, who invited me down to Mexico for Christmas 2007 which led to me meeting my beloved Jeannie! Funny old world!

Dan is a smart cookie. He holds a degree in psychology, as well as being a very easy guy to get along with.  We have been good friends for more than 30 years.

Anyway, back to the theme of the post; determining the truth of a complex issue.

Recently, Dan sent me an email with the subject heading of The Controversy Continues – A couple of Articles for your Digestive Tract….

The first article was:

Report shows UN admitting solar activity may play significant role in global warming

A leaked report by a United Nations’ group dedicated to climate studies says that heat from the sun may play a larger role than previously thought.

“[Results] do suggest the possibility of a much larger impact of solar variations on the stratosphere than previously thought, and some studies have suggested that this may lead to significant regional impacts on climate,” reads a draft copy of a major, upcoming report from the U.N.’s Intergovernmental Panel on Climate Change (IPCC).

The man who leaked the report, StopGreenSuicide blogger Alec Rawls, told FoxNews.com that the U.N.’s statements on solar activity were his main motivation for leaking the document.

The second article was from the Dick Morris website, from which I offer this extract (if, like me, you hadn’t heard of Mr. Morris before, details are here):

According to Bloomberg News, US carbon emissions are down 13% over the past five years and that they are now the lowest since 1994. In fact, we are more than halfway to President Obama’s goal of a 17% reduction below our peak year of 2007.

….

Coal has fallen to only 18% of our energy use (down from 23% in 2007) and natural gas is up to 31%. Natural gas has half the carbon emissions of coal.

Evidence suggests that climate change and global warming are happening, but at a much slower rate than doomsday warnings suggested. We are now on track for an increase in global temperatures of one degree centigrade by 2100. This increase is not enough to cause major flooding or rises in sea levels.

Please feel free to read the whole Dick Morris piece here.

So on the face of it, two convincing reports, especially the one from Alec Rawls.

Professor McPherson
Professor McPherson

Now let me turn to Professor Guy McPherson; professor emeritus at the University of Arizona.  Just take a peek at the professional recognition granted to Professor McPherson.

Guy McPherson writes a blog called Nature Bats Last.  It is described thus:

This blog focuses on the natural world, with a particular emphasis on the twin sides of our fossil-fuel addiction: (1) global climate change and (2) energy decline. Because these phenomena impact every aspect of life on Earth, specific topics range widely, and include philosophy, evolution, economics, humanity, politics, current events, and many aspects of the human condition.

Less than 3 months ago, Guy McPherson visited Greenfield Community College in western Massachusetts to deliver his presentation “The Twin Sides of the Fossil-Fuel Coin: Developing Durable Living Arrangements in Light of Climate Change and Energy Decline.

It lasts for just 40 minutes and needs to be watched.  Why do I say needs to be watched?  Because tomorrow I delve deeper into the challenges facing ordinary folk and watching the presentation and reflecting on the start of this post are very pertinent to following the scent of truth.

An ancient bond, indeed!

The mystery of the call of a dog in need of help.

Two days ago, I wrote a piece about how the evolution of the domestic dog has been reliably re-calibrated back to around 33,000 years ago.  I quoted from an article in the Arizona Republic, here are the opening paragraphs of that article.

Tamed dogs may go back 33,000 years

Dogs have been “man’s best friend” longer than any other animal. And, as it turns out, longer than previously thought.

A pair of research papers published in the past few years, one most recently by a team that includes the University of Arizona, significantly pushes back the timeline for domestication of dogs from about 14,000 years ago to more than 30,000 years ago.

Researchers at UA and universities in England and the Netherlands used radiocarbon dating to determine that the skull of a Siberian dog was about 33,000 years old. Slightly older dog remains were identified in Belgium a few years ago by a separate research team.

The full Post is here.

So moving on, and apologies for a bit of a personal muse.

Last night (the night of the 30th/31st Jan.) a single, gentle yelp from Pharaoh had me instantly awake. Initially hadn’t a clue about the time but instinctively knew it was an un-Godly hour!  Jean and I had been late to bed and I was pretty tired when the lights went out – off to sleep in an instant.  Ergo, waking up at 2am as it turned out to be, the classic deep-sleep time of the night, was challenging!  It is also relevant to mention that Pharaoh is reliably a very good sleeper at night.

Yet, in literally an instant of time, I had transitioned from being totally asleep to being mentally alert wondering what had caused him to cry out.  Pharaoh came to the side of the bed and let me rub his head, then went back to near the door and uttered another soft yelp.  I knew without any doubt at all that he was in pain and lay on my back anticipating what would be coming – putting a dressing-gown on and leading his nibs out into a very cold and dark night!

Then a clawed paw on the door told me to get moving, and within moments of Pharaoh being outside, it was clear that he had a badly upset tummy.

The whole episode was repeated around 4.45 am.

It was later in the morning that I was reflecting with Jean about the evolution of the dog-human relationship that a) gave the dog the instinctive confidence to call out to his ‘master’ in a different ‘I need help‘ tone, and b) that the call was so rapidly interpreted by a human as a call for help from another species.

But dogs sleeping near or around their human companions for more than 30,000 years allows plenty of time for species bonding to develop in ways that are both beautiful and mysterious.  Long may that bonding remain beautiful and mysterious.

Fabulous animals!

Pharaoh. June 2008, 3 months before we both left for Mexico!

Consciousness, science or God?

More of Peter Russell’s insightful ideas.

It was back in March, the 8th to be precise, when I first wrote about Peter Russell.  Well just over a week ago, I came across another article by Russell from the Huffington Post.  It was then a moment’s work to find it on Peter Russell’s own website.  (This links to various essays on the topic.)

Here’s a ‘taste’ from the first essay.

The Anomaly of Consciousness

Excerpted from book From Science to God

Science has had remarkable success in explaining the structure and functioning of the material world, but when it comes to the inner world of the mind science falls curiously silent. There is nothing in physics, chemistry, biology, or any other science that can account for our having an interior world. In a strange way, scientists would be much happier if there were no such thing as consciousness.

David Chalmers, professor of philosophy at the University of Arizona, calls this the “hard problem” of consciousness. The so-called “easy problems” are those concerned with brain function and its correlation with mental phenomena: how, for example, we discriminate, categorize, and react to stimuli; how incoming sensory data are integrated with past experience; how we focus our attention; and what distinguishes wakefulness from sleep.

It would be wrong to publish anything more so if you are interested in more, then go here and pick away or better still buy the book!

Arizona geology

An interesting insight into Arizona geology.

I’m taking a little gamble that the owners of the copyright in the following article will not mind the complete re-publishing of this piece.

While I have practically zero knowledge of the geology of much of the USA living here close to the Mogollon Rim makes it almost impossible not to sense the ageless beauty of the surrounding hills and mountains.  Anyway, this article was found on the Arizona Geology website. It is called Putting Earth Science Back in its Place, written by STEVEN SEMKEN of ARIZONA STATE UNIVERSITY.

The ancient landscape of Arizona

One of the most universal and fundamental things that humans do is to make places. We do this by sensing and experiencing the space around us, and attaching meanings to parts of it: here is a beautiful mountain, here is where my house is, here is where we have found copper, here is where my ancestors lived.  The meanings that we affix to places can be aesthetic, ceremonial, historic, practical, and mythical, as well as scientific. Humans develop emotional attachments to meaningful places, sometimes to the point of making significant personal sacrifices to preserve or protect them. The combination of meanings and attachments that connect us to places is called the sense of place.

We study and teach about Earth through its places. From Monument Valley to Organ Pipe, the landscapes of Arizona are set with places that are not only great geological exemplars, but meaningful to people for all kinds of reasons. It is only human for us to become interested in these diverse place meanings even as we explore our surroundings scientifically. Our students may also have, or can be encouraged to develop, rich senses of these places—particularly ones that are relevant to their personal interests, family experiences, or cultural backgrounds. This is the nature ofplace-based teaching, which encourages students to explore, and become involved in, local environments and communities. Urban places are just as meaningful, and can be just as instructive, as rural or remote places.

It is not simply teaching about the geology of a place such as Grand Canyon or the Río Salado Valley. It is finding ways for your students to experience the place: if possible by bringing them there, but alternatively by bringing them local rock specimens, images, maps, and readings to investigate, or enabling them to explore virtually using Google Earth. It is also helping them to become moreinvested in local places: by being able to explain how they get their weather, drinking water, fuel, and electrical power; by doing a community-service project; by creating art that celebrates the beauty of land and environment. And authentically place-based teaching and learning are as trans-disciplinary as place meanings themselves are. Here are reason and motivation for Earth science teachers to collaborate with their colleagues in life sciences, geography, history, language, literature, and so on, to develop ways to explore and understand the natural and cultural landscapes of Arizona across the curriculum.

Why is this important? On one hand, cultural forces such as the pervasiveness and popularity of digital entertainment and the homogenizing effects of global commerce conspire against student and community interest in local places and concerns. There is mounting research and anecdotal evidence that children and families spend less time outdoors. To be oblivious to the importance of local places is to forego opportunities to learn from them and protect them from environmental and cultural degradation. On the other hand, right here in Arizona we are already faced with a number of what many scientists and policymakers have labeled “grand challenges” to sustainability if not human existence, including depletion of water resources, lessened biodiversity, declining air quality, continued dependence on fossil energy, and climate change.  Place-based teaching is an appropriate response. And it is intellectually and emotionally delightful to reacquaint yourself and your students with the places of home.
