The Amount Of Carbon Dioxide In Our Air Just Reached A New Record, And Scientists Are Worried | ThinkProgress

On Monday, scientists at the National Oceanic and Atmospheric Administration’s Mauna Loa observatory in Hawaii told Climate Central that June would be be the third month in a row where, for the entire month, average levels of carbon dioxide were above 400 parts per million ppm. In other words, that’s the longest time in recorded history that this much carbon dioxide has been in the atmosphere.The finding is troubling to climate scientists, several of whom told ThinkProgress on Monday that the levels are a reminder that humans are still pumping too much carbon dioxide into the sky. If the trend continues, some said, carbon levels will soon surpass 450 ppm — a level that many scientists agree would create a level of global warming that would be too difficult for some humans to adapt to.“CO2 levels continue to increase, the amount of heat in the climate system continues to increase, ice continues to melt, and the seas continue to rise,” said Ken Caldeira, an atmospheric scientist at the Carnegie Institution for Science’s Department of Global Ecology. “We will continue to break through threshold after threshold — unless we stop using the sky as a waste dump soon.”
