NOAA research links human-caused CO2 emissions to dissolving sea snail shells off U.S. West Coast NOAA research links human-caused CO2 emissions to dissolving sea snail shells off U.S. West Coast For the first time, NOAA and partner scientists have connected the concentration of human-caused carbon dioxide in waters off the U.S. Pacific coast to the dissolving of shells of microscopic marine sea snails called pteropods.

Scientists test a new tool to improve local precipitation forecasts Scientists test a new tool to improve local precipitation forecasts A new weather forecasting tool could soon find itself part of the day-to-day operations of NOAA's National Weather Service (NWS). The instrument, called Atmospheric Emitted Radiance Interferometer, or AERI, measures temperature, water vapor and trace gases (like ozone, carbon monoxide and methane) in the lowest layer of Earth’s atmosphere, the troposphere. Now, an AERI project led by Tim Wagner, a scientist with NOAA’s Cooperative Institute for Meteorological Satellite Studies (CIMSS) at the University of Wisconsin–Madison, has received funding through NOAA’s Joint Technology Transfer Program.

Study shows ocean acidification is two-front assault on coral reefs Study shows ocean acidification is two-front assault on coral reefs Scientists studying coral reefs in volcanically acidified water of the southwestern Pacific Ocean measured a net loss of coral reef skeletons due to increased bio-erosion, according to new research by NOAA, the Cooperative Institute for Marine and Atmospheric Studies (CIMAS) and Australian scientists.

Q&A: Is Arctic warming fueling severe winter weather in the mid-latitudes? Q&A: Is Arctic warming fueling severe winter weather in the mid-latitudes? We caught up with James Overland, oceanographer at NOAA’s Pacific Marine Environmental Lab, to hear about his latest research on whether Arctic warming is fueling more severe winter weather in the mid-latitudes, the temperate zone of the Earth between the tropics and the Arctic, and the part of the United States where most Americans live.

Antarctic ozone hole about average in 2016 Antarctic ozone hole about average in 2016 Results are consistent with expectations, scientists say The hole in the Earth’s ozone layer that forms over Antarctica each September grew to about 8.9 million square miles in 2016 before starting to recover, according to scientists from NOAA and NASA who monitor the annual phenomenon.

A Year Locked in Ice 20Sep2019 Read more An expedition to the central Arctic will give scientists the first opportunity to study the dramatic changes sweeping across the top of the world for an entire year. Read more
Old weather “time machine” opens a treasure trove for researchers 9Oct2019 Read more https://cires.colorado.edu/A NOAA-funded research team ha published an update the 20th Century Reanalysis Project, a dauntingly complex, high-resolution, four-dimensional reconstruction of the global climate that estimates what the weather was for every day back to 1836.

Indo-Pacific Ocean warming is changing global rainfall patterns 27Nov2019 Read more New research by NOAA and a visiting scientist from India shows that warming of the Indo-Pacific Ocean is altering rainfall patterns from the tropics to the United States, contributing to declines in rainfall on the United States west and east coasts.

Heat waves could increase substantially in size by mid-century, says new study 7Oct2019 Read more Our planet has been baking under the sun this summer as temperatures reached the hottest ever recorded and heat waves spread across the globe. While the climate continues to warm, scientists expect the frequency and intensity of heat waves to increase. However, a commonly overlooked aspect is the spatial size of heat waves, despite its important implications. Read more
