A new look at old smoke finds it has an important role in regulating the climate A new look at old smoke finds it has an important role in regulating the climate A NOAA study published in Nature Geosciences takes a new look at faint, old smoke and finds that it is just as important an influence on the climate as the thick plumes produced by active fires.

Rise of carbon dioxide unabated 4Jun2020 Read more Atmospheric carbon dioxide measured at Mauna Loa Observatory reached a seasonal peak of 417.1 parts per million for 2020 in May, the highest monthly reading ever recorded. Monthly CO2 values at Mauna Loa first breached the 400 ppm threshold in 2014, and are now at levels not experienced by the atmosphere in several million years. Read more

Dangerous humid heat extremes occurring decades before expected 8May2020 Read more Climate models project that combinations of heat and humidity could reach deadly thresholds for anyone spending several hours outdoors by the end of the 21st century. However, new NOAA-supported research says these extremes are already happening — decades before anticipated — due to global warming to date. Read more
Warming influence of greenhouse gases continues to rise, NOAA finds 28May2020 Read more NOAA’s Annual Greenhouse Gas Index tracks the concentrations of greenhouse gases being added to the atmosphere principally from human-caused emissions. The AGGI then calculates the heat being added to Earth's atmosphere and oceans as a result. Read more
