THE APPROACHING ECOLOGICAL PRECIPICE:
Science today tells us that we have a generation at most in which to carry out a radical transformation in our economic relations, and our relations with the earth, if we want to avoid a major tipping point or "point of no return," after which vast changes in the earth's climate will likely be beyond our ability to prevent and will be irreversible. At that point it will be impossible to stop the ice sheets in Antarctica and Greenland from continuing to melt, and thus the sea level from rising by as much as "tens of meters." Nor will we be able to prevent the Arctic sea ice from vanishing completely in the summer months, or carbon dioxide and methane from being massively released by the decay of organic matter currently trapped beneath the permafrost--both of which would represent positive feedbacks dangerously accelerating climate change. Extreme weather events will become more and more frequent and destructive. An article in the Proceedings of the National Academy of Sciences demonstrated that the record-breaking heat wave that hit the Moscow area in 2010 with disastrous effect was made five times more likely, in the decade ending in that year as compared with earlier decades, due to the warming trend, implying "an approximate 80% probability" that it "would not have occurred without climate warming." Other instances of extreme weather such as the deadly European heat wave in 2003 and the serious drought in Oklahoma and Texas in 2011, have been shown to be connected to earth warming. Hurricane Sandy, which devastated much of New York and New Jersey at the end of October 2012, was impacted and amplified to a considerable extent by climate change.
