The atmospheric concentration of carbon dioxide reached a new high of 407.7 parts per million, a 3.76 ppm increase since last May, as measured at the Mauna Loa Observatory in Hawaii.

According to the National Oceanic and Atmospheric Administration, the planet last saw such an increase in carbon dioxide between 17,000 and 11,000 years ago.

Last month, Arctic ice levels hit a record low, with the average area of sea ice on the Arctic Ocean being just 4.63 million square miles, according to the National Snow and Ice Data Center. This follows previous record lows set this year in January, February and April.

The EPA announced last week that it is issuing a preliminary regulatory determination for public comment to set an enforceable drinking water standard to two of the most common and well-studied PFAS, PFOA and PFOS.

This decision is based on three criteria:

  1. PFOA and PFOS have an adverse effect on public health
  2. PFOA and PFOS occur in drinking water often enough and at levels of public health concern;
  3. regulation of PFOA and PFOS is a meaningful opportunity for reducing the health risk to those served by public water systems.
