CO2 in the atmosphere just exceeded 415 parts per million for the first time in human history.
The human race has broken another record on its race to ecological collapse.
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.
This is the first time in human history our planet's atmosphere has had more than 415ppm CO2.
Not just in recorded history, not just since the invention of agriculture 10,000 years ago.
The increasing proportion of carbon dioxide in the atmosphere is important because of its heat absorbing properties.
The NOAA likens CO2 to leaving bricks in a fireplace that still emit heat after a fire goes out. »
