CO2 crosses dreaded 400 ppm milestone, and science is very disappointed in you

“Del Boca Vista is underwater, thanks to you!” We already told you that carbon dioxide could pass a daily average of 400 parts per million (ppm) sometime this May — an atmospheric concentration not seen in human history, and generally a sign that we’re passing into the climatological period known as “the gnashing of teeth.” The New York Times now reports that we’ve Usain Bolted past that milestone : Scientific monitors reported that the gas had reached an average daily level that surpassed 400 parts per million — just an odometer moment in one sense, but also a sobering reminder that decades of efforts to bring human-produced emissions under control are faltering. The best available evidence suggests the amount of the gas in the air has not been this high for at least three million years, before humans evolved, and scientists believe the rise portends large changes in the ...
