Antarctic CO2 Hit 400 PPM
Carbon dioxide has been steadily rising since the start of the Industrial Revolution, setting a new high year after year. There’s a notable new entry to the record books. The last station on Earth without a 400 parts per million (ppm) reading has reached it.
Record annual increase of carbon dioxide
“The annual growth rate of atmospheric carbon dioxide measured at NOAA’s Mauna Loa Observatory in Hawaii jumped by 3.05 parts per million during 2015, the largest year-to-year increase in 56 years of research.
In another first, 2015 was the fourth consecutive year that CO2 grew more than 2 ppm, said Pieter Tans, lead scientist of NOAA’s Global Greenhouse Gas Reference Network.
‘Carbon dioxide levels are increasing faster than they have in hundreds of thousands of years,’ Tans said. ‘It’s explosive compared to natural processes.'”
EPA Protects Communities from sulfur dioxide air pollution
“The U.S. Environmental Protection Agency (EPA) identified 12 new areas across the United States today where residents regularly breathe dangerous levels of sulfur dioxide air pollution. The EPA has proposed designating these areas as being in violation of the 2010 health-based clean air standard for sulfur dioxide and, if they are finalized, it will prompt states to create clean up plans to protect at-risk communities.”
