Research: Global warming contributed to decline in tropical cyclones in the 20th century Research: Global warming contributed to decline in tropical cyclones in the 20th century The annual number of tropical cyclones forming globally has decreased by approximately 13% during the 20th century, and scientists say the main cause is a rise in global warming, according to a new study in Nature Climate Change by a group of international scientists including NOAA scientists.

New research estimates the future emissions of potent greenhouse gases New research estimates the future emissions of potent greenhouse gases New research published in Atmospheric Chemistry and Physics projects future emissions of hydrofluorocarbons (HFCs), a class of potent greenhouse gasses, based on recent trends and compliance with current policies. The ability to observe trends of these compounds in the atmosphere is made possible by the long-term record of observations produced by the Halocarbons and other Atmospheric Trace Species (HATS) Division within NOAA’s Global Monitoring Laboratory.

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
