I’m worried. I’m very worried.
The recent report by MIT on Climate Change was the
most comprehensive modeling yet carried out on the likelihood of how much hotter the Earth’s climate will get in this century
It found that
without rapid and massive action, the problem will be about twice as severe as previously estimated six years ago – and could be even worse than that.
Specifically the peer-reviewed study projects a 90% probability range of a global warming of 3.5 to 7.4 degrees Celsius by 2100 with a median probability of surface warming of 5.2 degrees Celsius.
To put that in context, John Holdren, Barack Obama’s Director of the White House Office of Science and Technology Policy, says that the last time the earth was 3 degrees Celsius warmer was 120 million years ago. At that time there were palm trees in Wyoming, crocodiles swimming off the coast of Greenland and sea levels were 20-30m higher. Note – that was 3 degrees Celsius warmer, not the 3.5 degrees which is at the low end of the 90% probability the MIT paper.
The planet and more importantly, all life on it has had 120m years to adapt to the 3 degree cooling which has occurred since then and we have adapted well. However, a rise of 3 degrees in less than 100 years would have catastrophic consequences for most plant and animal species on the planet who are designed to adapt to changes in geological timeframes, not generational ones.
Against this backdrop you have the Barack Obama administration back-pedalling furiously on their climate commitments. Energy Secretary Steven Chu has said he is no longer willing to block the construction of new coal-powered electricity plants in the US, despite the chairman of the Federal Energy Regulatory Commission Jon Wellinghoff recently announcing no new nuclear or coal plants may ever be needed in the United States!
Further, the current climate bill working its way through the system in the US calls for a 17% reduction in carbon emissions compared to the 2005 figure. Compare that to the much more ambitious 40% reduction on 1990 emissions that the Chinese are calling for and you start to see just how uninspired the US position appears to be.
People need to watch the video above, grow a pair and act decisively on the problem. Enough of the half-measures.
