For two straight years — 2015 and 2016 — atmospheric carbon dioxide has climbed by more than 3 parts per million.

According to data from the National Oceanic and Atmospheric Administration, carbon dioxide levels jumped by three parts per million in both 2015 and 2016 and now rest at about 405 parts per million.

It’s the biggest jump ever observed at the agency’s Mauna Loa Baseline Atmospheric Observatory in Hawaii, where the measurements were recorded. Similar observations have been recorded at stations all over the world, said Pieter Tans, who leads the Carbon Cycle Greenhouse Gases group at NOAA’s Greenhouse Gas Reference Network.

Throughout the last decade, the average rate of increase has been around 2.3 parts per million per year, Tans added.
