Like a rite of spring, carbon dioxide is poised to cruise pass the previous mark set last year and reach heights unseen in human history. In the coming weeks, carbon dioxide will start to breach the 410 parts per million threshold on a daily basis at the Mauna Loa Observatory in Hawaii. The monthly average for May could come close to topping 410 ppm, too, according to the U.K. Met Office’s inaugural carbon dioxide forecast, released last week.

Richard Betts, a climate scientist who helped create the forecast, said we should pass last year’s record-setting monthly peak by April or even as soon as this month.
