The success of President Joe Biden ’s climate bill, which he’s slated to sign Tuesday, will not be judged by polls, or by the price of gas at the pump, or by the ferocity of the next hurricane that hits the Gulf Coast. It will be measured in the clear air high above the Pacific Ocean at the Mauna Loa Observatory in Hawaii. In 1958, when scientist Charles Keeling began measuring CO2 in the atmosphere at Mauna Loa, the level was 316 parts per million (250 years ago, before the industrial era, it was 280 ppm). Today, 63 years later, the CO2 level is 416 ppm, an increase of roughly a third over pre-industrial levels. It’s the accumulation of this molecule that’s trapping heat in the atmosphere, causing oceans to rise, forests to burn, and extreme heat waves to cook cities. By measuring CO2, Keeling began what amounts to a diary of our march toward climate chaos. What’s most remarkable about The Keeling Curve , as the chart of atmospheric CO2 levels is called, is it’s unbroken … [Read more...] about The Biden Climate Bill: Will It Save Us?
