The annually updated figure is included in the latest version of ClimatePositions with impact on the national Climate 2021-04-06 2013-05-22 In 2016, an even more significant milestone was reached: the global annual minimum levels of CO2 in the atmosphere measured above 400 ppm. To understand the significance of this milestone, it is necessary to understand that atmospheric CO2 levels are cyclical, with annual maximums and minimums. CO2 peaks in May every year. 2014-01-07 Yet another alarming milestone of humanity's damaging effect on the environment has now officially been reached – crossing a barrier into a hot, polluted future like the planet hasn't witnessed in millions of years.

When the National Oceanic and Atmospheric Administration (NOAA) research station "began collecting CO2 measurements in the late 1950s, atmospheric CO2 concentration sat at around 315 PPM," the Washington Post reported. "On Saturday, the daily average was pegged at 421.21 PPM—the first time in human history that number has been so high."
