Carbon Dioxide Levels Hit Historic High At 415.26 PPM


For the first time in human history — not recorded history, but since humans have existed on Earth — carbon dioxide in the atmosphere has topped 415 parts per million, reaching 415.26 parts per million, according to sensors at the Mauna Loa Observatory, a research outpost of the National Oceanic and Atmospheric Agency.
The increasing proportion of carbon dioxide in the atmosphere is important because of its heat absorbing properties. The land and seas on the planet absorb and emit heat, and that heat is trapped in carbon dioxide molecules. 
Greenhouse gases contribute to the planet maintaining a temperature that can sustain life, but too much can impact the entire ecosystem that sustains us. That’s what’s happening now.
