Atmospheric carbon dioxide reached a new high in April.
“The average concentration of carbon dioxide in the atmosphere was 410.31 parts per million (ppm) for the month of April, according to the Keeling Curve measurement series made at the Mauna Loa Observatory in Hawaii.” – Scripps Institution of Oceanography
The target level, which we exceeded years ago, is 350 ppm. Despite progress in technology and lifestyle adjustments, the trend is accelerating. The longer the trend rises, the longer before it can recover, and the more likely the climate won’t be able to recover. Evidence in sea ice, temperature extremes, and ocean currents suggest we will experience more and larger environmental upsets before any recovery is accomplished.
