Margery Moore’s Alberta Tar Sands Journey: March 10th, 2010-03-07, 7:00am

I have been asked a few times now, why Alberta tar sands? Why not save BC shorelines from oil and gas exploration? Why don’t you draw attention to that? Focus on more local issues?
Point taken. I hear you!
So what is it about the tar sands that gets me? It is the scale of the impact coupled with [...]

“The Arctic could be primed for major, even irreversible, changes”

As Arctic climatologist David Barber and his colleagues explain in a recent paper in Geophysical Review Letters, the analysis of what the satellites were seeing was wrong. Some of what satellites identified as thick, melt-resistant multiyear ice turned out to be, in Barber’s words, “full of holes, like Swiss cheese. We haven’t seen this sort of thing before.”
What Barber’s expedition further discovered was that some Arctic sea ice is not only whisper thin, but that even in places with thick ice, the ice was not as solid as satellites had indicated. That thick ice was still there, but largely as individual chunks covered with a veneer of new ice that masked their true nature.

Tipping Point, After Tipping Point…

Another disturbing milestone was passed on November 6. The graph below shows that although extent of the Arctic sea ice this past summer was greater than that of 2007, it is now less, a record low for its date. Ice covered the Arctic Ocean in a smaller area on November 6, 2009 than in any other year on November 6 since observations began in 1979.

Australian Professor Writes of the Likelihood of Runaway Climate Change

Rather than decarbonising, the world is carbonising at an unprecedented rate, and it is doing so at precisely the time we know we have to stop it. 2.5 degrees Celsius is likely by the end of the century in spite of our childlike belief that climate change can be averted; the cost will prove incalculable.

New Warnings of Catastrophic Global Warming in Our Lifetimes

“We’ve always talked about these very severe impacts only affecting future generations, but people alive today could live to see a 4C rise,” said Richard Betts, the head of climate impacts at the Met Office Hadley Centre, who will announce the findings today at a conference at Oxford University. “People will say it’s an extreme scenario, and it is an extreme scenario, but it’s also a plausible scenario.”

The Link Strong Between Carbon Dioxide and Global Warming

The science is clear: global warming is happening faster than ever and humans are responsible. Global warming is caused by releasing what are called greenhouse gases into the atmosphere. The most common greenhouse gas is carbon dioxide

NOW is the time for ALL parties to take Action for a Low Carbon and Equitable Future

The St James’s Palace Memorandum calls for a global deal on climate change that matches the scale and urgency of the human, ecological and economic crises facing the world today. It urges governments at all levels, as well as the scientific community, to join with business and civil society to seize hold of this historic opportunity to transform our carbon-intensive economies into sustainable and equitable systems. We must recognize the fierce urgency of now.

Inspirational Whimsy: The Great Flower Pot in the Sky

Here we are, after all this time of evolution in danger of “losing it,” of allowing the disruptive forces of runaway climate change to devastate our species and most of the living organisms that share our “pot.”

Let’s not let this happen. We’re becoming beautiful, and with all our faults, we’re worth saving. Let’s fight, let’s shout, let’s shake things to ensure our survival.

To celebrate, or to mourn, Earth Day

Our scientists have done a great service in defining the treacherous path that awaits. Now artists and artisans must heed that call, and bring their talent and creativity to bear. We need to breathe life into this message, so that our brothers and sisters, our politicians, our teachers, our manufacturers and regulators will hear the cry, and create justice for those who follow. Artists must get informed, and act boldly. We need our writers, poets, designers, sculptors, inventors, and musicians to use their creativity to bring action to a world that sorely needs it.
