Forget the sodding polar bears

Forget the sodding polar bears: this is about all of us. As the ice disappears, the region becomes darker, which means that it absorbs more heat. A recent paper published in Geophysical Research Letters shows that the extra warming caused by disappearing sea ice penetrates 1500km inland, covering almost the entire region of continuous permafrost(4). Arctic permafrost contains twice as much carbon as the entire global atmosphere(5). It remains safe for as long as the ground stays frozen. But the melting has begun. Methane gushers are now gassing out of some places with such force that they keep the water open in Arctic lakes, through the winter(6).

The effects of melting permafrost are not incorporated into any global climate models. Runaway warming in the Arctic alone could flip the entire planet into a new climatic state. The Middle Climate could collapse faster and sooner than the grimmest forecasts proposed.

Barack Obama’s speech to the US climate summit last week was an astonishing development. It shows that, in this respect at least, there really is a prospect of profound political change in America. But while he described a workable plan for dealing with the problem perceived by the Earth Summit of 1992, the measures he proposes are now hopelessly out of date. The science has moved on. The events the Earth Summit and the Kyoto process were supposed to have prevented are already beginning. Thanks to the wrecking tactics of Bush the elder, Clinton (and Gore) and Bush the younger, steady, sensible programmes of the kind that Obama proposes are now irrelevant. As the PIRC report suggests, the years of sabotage and procrastination have left us with only one remaining shot: a crash programme of total energy replacement. One Shot Left

Now is the time to focus on what is important...it feels like rearranging deck chairs on the Titanic time sometimes to me...

We've been getting closer and closer to the edge for years, but we had a society and ruling class in the USA that refused to look at things realistically, so now its come rushing at us all at once. That doesn't change the facts, which paint a picture that is more and more desperate.

The One Shot Left essay continues.

This approach is challenged by the American thinker Sharon Astyk. In an interesting new essay, she points out that replacing the world’s energy infrastructure involves “an enormous front-load of fossil fuels”, which are required to manufacture wind turbines, electric cars, new grid connections, insulation and all the rest(13). This could push us past the climate tipping point. Instead, she proposes, we must ask people “to make short term, radical sacrifices”, cutting our energy consumption by 50%, with little technological assistance, in five years. There are two problems: the first is that all previous attempts show that relying on voluntary abstinence does not work. The second is that a 10% annual cut in energy consumption while the infrastructure remains mostly unchanged means a 10% annual cut in total consumption: a deeper depression than the modern world has ever experienced. No political system - even an absolute monarchy - could survive an economic collapse on this scale.

She is right about the risks of a technological green new deal, but these are risks we have to take. Astyk’s proposals travel far into the realm of wishful thinking. Even the technological solution I favour inhabits the distant margins of possibility. Can we do it? Search me. Reviewing the new evidence, I have to admit that we might have left it too late. But there is another question I can answer more easily. Can we afford not to try? No we can’t.
