Scientists tell us we have a 10-year window — if even that — before catastrophic climate change becomes inevitable and irreversible. The threat is real, and time is not on our side.
Facts, as John Adams said, are stubborn things. Here are a few you need to know: Atmospheric carbon-dioxide levels have risen 38% in the industrial era, from 280 to 385 parts per million (ppm). Scientists have warned that anything above 450 ppm — a warming of 2 degrees Celsius — will result in an unacceptable risk of catastrophic climate change.
The truth is that the threat we face is not an abstract concern for the future. It is already upon us and its effects are being felt worldwide, right now. Scientists project that the Arctic will be ice-free in the summer of 2013. Not in 2050, but four years from now.”
