Climate scientists confirm CO2 at over 400 ppm
Atmospheric carbon dioxide (CO2) levels climbed above the 400 parts per million (ppm) at the Mauna Loa Observatory – a network for the observation of atmospheric change. The researchers believe that it is distinctly possible they won’t be back below that level again in our lifetimes.
CO2 measurements at Mauna Loa have been supported for many years by the U.S. Department of Energy (DOE), and have more recently been supplemented by Earth Networks, a technology.
The burning of fossil fuels are widely believed to have driven atmospheric CO2 to levels that world hasn’t seen in at least 400,000 years.
That has driven up temperatures, melted ice and caused oceans to acidify. Some extreme weather events around the world have become more likely and stronger because of it, and some will likely only get worse as the planet continues to warm.
