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.

Rise of carbon dioxide unabated 4Jun2020 Read more Atmospheric carbon dioxide measured at Mauna Loa Observatory reached a seasonal peak of 417.1 parts per million for 2020 in May, the highest monthly reading ever recorded. Monthly CO2 values at Mauna Loa first breached the 400 ppm threshold in 2014, and are now at levels not experienced by the atmosphere in several million years. Read more
NOAA exploring impact of COVID-19 response on the environment 6May2020 Read more NOAA has launched a wide-ranging research effort to investigate the impact of reduced vehicle traffic, air travel, shipping, manufacturing and other activities on Earth’s atmosphere and oceans due to the response to COVID-19.

Dangerous humid heat extremes occurring decades before expected 8May2020 Read more Climate models project that combinations of heat and humidity could reach deadly thresholds for anyone spending several hours outdoors by the end of the 21st century. However, new NOAA-supported research says these extremes are already happening — decades before anticipated — due to global warming to date. Read more
Warming influence of greenhouse gases continues to rise, NOAA finds 28May2020 Read more NOAA’s Annual Greenhouse Gas Index tracks the concentrations of greenhouse gases being added to the atmosphere principally from human-caused emissions. The AGGI then calculates the heat being added to Earth's atmosphere and oceans as a result. Read more
NOAA teams with United Nations to create locust-tracking application 7May2020 Read more NOAA’s powerful air quality model used to track pollution from wildfires, volcanoes and industrial accidents is now being used to help warn communities across Africa and Asia of what have been called the worst locust swarms in a quarter century.
