Carbon Dioxide Hits Record High in April
The average level of CO2 in the atmosphere for the first time topped 400 parts per million for a full month, according to the Scripps Institution of Oceanography at UC San Diego.
Last May, the Mauna Loa Observatory in Hawaii for the first time measured carbon dioxide at greater than 400 parts per million, averaged over one day. C02 exceeded 400 parts per million two months earlier this year than last year, according to researchers at NOAA.
But now we've hit an unwelcome milestone, with every day in April averaging more than 400 parts per million.
It's likely this record-breaking moment marks the first time in 800,000 years that the Earth's atmosphere contained this much CO2.
