Over a year ago, I was directed to a scientific paper by two scientists from NASA’s Goddard Institute, Pushker A. Kharecha and James Hansen, which compared our known reserves of fossil fuels with the carbon we can safely burn without undue risk of destabilizing our climate. This paper concluded that in order to contain atmospheric carbon dioxide below 450 ppm, which would raise global temperatures about 2 degrees above preindustrial levels, we would need to cut down on our use of coal and unconventional oil (like the tar sands), as well as emissions from deforestation.     Read more »

These are hard times for those of us working on climate change – scientists, environmentalists, policymakers and others.  The breathless rumours about the death of climate change science from denialists are not only premature, however, they are contrary to what anyone working in the field knows and understands.  The real question is whether we will embrace the science in time to prevent catastrophe.

I was studying Anthropology at the University of Toronto in the early 1980s.  At that time, Richard Leakey and Donald Johanson were embroiled in a bitter feud about the significance of Australopithecus afarensis.  Johanson had found remains of the 3.2 million year old hominid and was sure that it was a human ancestor.  Leakey was initially unwilling even to acknowledge that it deserved its own species name.  Johanson was still fighting off accusations of professional misconduct because he publicized his findings in a popular magazine and gave the specimen the catchy name “Lucy” before submitting his research to peer-review.  Some old textbooks that we used still referred to Piltdown Man, which had been revealed as a fraud four decades before.     Read more »

Just got the news.  Best wishes for a speedy recovery!

I’ve wanted to write for a while about Afghan prisoner issues, but for a while every day brought new revelations.  And now for days I’ve wanted to write about the prorogation of Parliament, but I’m honestly stumped about what to say.  And obviously I’m heartily ashamed of Canada’s performance at Copenhagen, which earned us the “Fossil of the Year”  award once again.

Maude Barlow ties all this together, and more, here.

I watched Avatar with my family on New Year’s Day and highly recommend it.  One of my friends described it as a futuristic Pocahontas story that ends well for the natives.  He also found it amusing that the substance for which mankind was willing to lay waste to the beautiful moon of Pandora was called unobtainium.  Spoilers ahead.     Read more »
