Writing in The Daily Beast, the senator warns:
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.
And the characteristic refrain, painted over with stars and stripes, goes:
The bottom line is that failure to tackle climate change risks much more than a ravaged environment: It risks a much more dangerous world, and a gravely threatened America.
Echoes of An Inconvenient Truth? Why aren’t we surprised?
Perhaps the good senator, who hails from the cornfields of Iowa, should have read The Stern Review instead.
