"Last week, an exquisitely sensitive instrument located in a metal shack on the top of Mauna Loa, a 13,679-foot-high volcano in Hawaii, recorded a terrifying human achievement: Thanks to our ever-increasing addiction to burning fossil fuels, the level of carbon dioxide in the Earth’s atmosphere has risen to 415 parts per million. This is the highest level it has been since human beings have lived on Earth. And it is further evidence (as if further evidence were needed) of just how hell-bent we are on cooking the planet we live on."
