New hurricane research supports advances to NOAA’s 2022 forecasts New hurricane research supports advances to NOAA’s 2022 forecasts This summer during the 2022 Atlantic hurricane season, scientists at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) will once again be on the frontlines helping NOAA prepare the public for severe weather. They will also conduct new research on the complex processes of how tropical cyclones form, develop, and dissipate. Read more
Greenhouse gas pollution trapped 49% more heat in 2021 than in 1990, NOAA finds Greenhouse gas pollution trapped 49% more heat in 2021 than in 1990, NOAA finds The Annual Greenhouse Gas Index serves as a measure of global society's progress - or lack of progress - in reducing greenhouse gas emissions.

Evaporative demand increase across lower 48 states means less water supplies, drier vegetation, and higher fire risk Evaporative demand increase across lower 48 states means less water supplies, drier vegetation, and higher fire risk In the western U.S., the impacts of drought conditions in the 21st century are increasingly evident as extended fire seasons, dwindling water supplies, and widespread tree mortality are becoming more common occurrences.

Study: Reducing human-caused air pollution in North America & Europe brings surprise result: more hurricanes Study: Reducing human-caused air pollution in North America & Europe brings surprise result: more hurricanes Research also finds that increased pollution in Asia may reduce tropical cyclones 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

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
Study validates accuracy of NOAA’s smoke forecasting model during the Camp Fire 5Jul2022 Read more A research team led by scientists from the University of California Berkeley and NOAA found that HRRR-Smoke accurately predicted the intensification of smoke pollution from the Camp Fire. Read more
