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.
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.
The Annual Greenhouse Gas Index serves as a measure of global society's progress - or lack of progress - in reducing greenhouse gas emissions.
Accurate, high resolution weather forecasts equate to cost savings across many different industries, but it is not always clear exactly what those cost savings are.
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.
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.
Have you ever wondered what animals might be present in a particular habitat or traveled through a certain area of the ocean? Scientists are able to use environmental DNA or “eDNA” sampling to help answer those questions.
A new study found that when red tides began in early summer and continued into the fall, low oxygen areas—or dead zones— were more likely to also occur.
New climate modeling research shows heavy rainfall events will cause more frequent and stronger flash floods by the end of the century, especially in the southwest and central United States.
NOAA atmospheric measurements are helping to support a national inventory of emissions from an important family of greenhouse gases.
