Amount of carbon dioxide in air keeps rising, hits milestone

1 post in this topic

WASHINGTON (AP) -- Global levels of carbon dioxide, the most prevalent heat-trapping gas, have passed a daunting milestone, federal scientists say.

The National Oceanic and Atmospheric Administration says in March, the global monthly average for carbon dioxide hit 400.83 parts per million. That is the first month in modern records that the entire globe broke 400 ppm, reaching levels that haven't been seen in about 2 million years.

"It's both disturbing and daunting," said NOAA chief greenhouse gas scientist Pieter Tans. "Daunting from the standpoint on how hard it is to slow this down."

He said it is disturbing because it is happening at a pace so fast that it seems like an explosion compared to Earth's slow-moving natural changes.

Carbon dioxide isn't just higher, it is increasing at a record pace, 100 times faster than natural rises in the past, Tans said.
