A sea change in the Arctic atmosphere A sea change in the Arctic atmosphere Thinning sea ice in spring affects ozone chemistry with implications for mercury contamination Arctic warming has thinned springtime sea ice across the Arctic Ocean. A new study shows that this alters the chemistry of the atmosphere near the Earth’s surface and may increase the amount of toxic mercury contaminating the region. Read more

Study: Reducing human-caused air pollution in North America & Europe brings surprise result: more hurricanes 11May2022 Read more A new NOAA study published today in the journal Science Advances about four decades of tropical cyclones reveals the surprising result that reducing particulate air pollution in Europe and North America has contributed to an increase in the number of tropical cyclones in the North Atlantic basin and a decrease in the number of these storms in the Southern Hemisphere. The study also found that the growth of particulate pollution in Asia has contributed to fewer tropical cyclones in the western North Pacific basin. Read more
Greenhouse gas pollution trapped 49% more heat in 2021 than in 1990, NOAA finds 23May2022 Read more The Annual Greenhouse Gas Index serves as a measure of global society's progress - or lack of progress - in reducing greenhouse gas emissions. Read more
Projected increase in space travel may damage ozone layer 21Jun2022 Read more Scientists from NOAA and The Aerospace Corp. modeled the climate response of the stratosphere to increased future emissions of black carbon from rockets burning kerosene fuel. Read more
NOAA and Saildrone launch seven hurricane-tracking surface drones 3Aug2022 Read more In partnership with NOAA, Saildrone Inc. is deploying seven ocean drones to collect data from hurricanes during the 2022 hurricane season with the goal of improving hurricane forecasting. For the first year, two saildrones will track hurricanes in the Gulf of Mexico. Read more
