CO2 Levels Hit Record High As Arctic Sea Ice Hits Record Low

Last month saw the biggest year-over-year jump in atmospheric levels of heat-trapping carbon dioxide on record — 3.76 parts per million. And that, reports NOAA, took May 2016 to the highest monthly levels of CO2 in the air ever measured — 407.7 ppm.

At the same time, the National Snow and Ice Data Center reports the warming-driven death spiral of Arctic sea ice hit a staggering new May low (see figure). May 2016 saw Arctic sea ice extent drop “about 600,000 square kilometers (232,000 square miles) below any previous year in the 38-year satellite record.”
