New Threshold: 2015 Saw Average Carbon Dioxide Levels of 400 PPM

HeadlineOct 25, 2016

The planet has crossed a new threshold: The average carbon dioxide levels in the atmosphere throughout 2015 was 400 parts per million. This according to the World Meteorological Organization. Scientists have long warned carbon dioxide levels must remain below 400 parts per million—if not below 350 parts per million—to avoid catastrophic climate change. Scientists predict the carbon dioxide levels will not dip below 400 parts per million on average for decades to come, even if there are aggressive measures taken to cut global carbon emissions. 2016 is also slated to be the hottest year on record.
