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.

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.

Carbon dioxide peaks near 420 parts per million at Mauna Loa observatory 7Jun2021 Read more In May, NOAA's measurements at the Mauna Loa observatory averaged 419.13 parts per million. Scientists at Scripps calculated a monthly average of 418.92 ppm. It's the highest level since accurate measurements began 63 years ago. Read more
NOAA index tracks how greenhouse gas pollution amplified global warming in 2020 24May2021 Read more The annual analysis of samples collected by NOAA’s Global Greenhouse Gas Reference Network provides an updated measure of the excess heat trapped in the atmosphere by greenhouse gas pollution.
