"In an otherwise unremarkable day last week--November 11, 2015 (noted mainly for being Veterans Day in the U.S.)--a crucial milestone in global climate was quietly transcended. The daily average concentration of carbon dioxide in the air that day at Hawaii's Mauna Loa Observatory was 399.68 parts per million. On November 12 it rose to 401.64 ppm, and it's quite possible that we'll never see another day in our lives with the daily Mauna Loa CO2 reading below 400 ppm. Greenhouse gases have been building in our atmosphere for more than a century, so this news doesn't come as a shock so much as a reminder of what our continued use of fossil fuels is doing to the atmosphere."
