NOAA report highlights 2020 climate, weather, ocean research NOAA report highlights 2020 climate, weather, ocean research Launching uncrewed systems to monitor climate and ecosystem changes in the U.S. Arctic, sequencing the genome for endangered marine species, and improving weather forecasts with advances in regional models — these are just a few of NOAA’s scientific achievements in 2020. The newly released 2020 NOAA Science Report highlights the ways these accomplishments — and many more — provide the foundation for vital services that Americans use every day. Read more
Frigid Arctic air outbreaks may be predictable, new research suggests Frigid Arctic air outbreaks may be predictable, new research suggests Known for precipitating outbreaks of Arctic air, stratospheric events in polar regions often cause other kinds of extreme weather. Since the stratosphere takes a long time to recover after these events, scientists may be able to improve predictability of extreme weather weeks ahead of time. Read more
Congress reauthorizes law supporting partnerships to advance ocean science Congress reauthorizes law supporting partnerships to advance ocean science Congress voted on January 1, 2021 to reauthorize and strengthen the National Oceanographic Partnership Program, a 23-year old program created by Congress to facilitate ocean-related partnerships between federal agencies, academia and industry to advance ocean science research and education.The reauthorization passed Congress as an amendment included in Section 1055 of the National Defense Authorization Act for Fiscal Year 2021.

Sea ice loss and extreme wildfires mark another year of Arctic change Sea ice loss and extreme wildfires mark another year of Arctic change NOAA’s 15th Arctic Report Card catalogs for 2020 the numerous ways that climate change continues to disrupt the polar region, with second-highest air temperatures and second-lowest summer sea ice driving a cascade of impacts.

Monitoring Change in the Arctic Monitoring Change in the Arctic Expedition to the U.S. Arctic keeps in place some vital research While NOAA has had to cancel many of its planned research surveys in Alaska, it has been able to conduct a number of scaled-back research surveys in 2020. One such survey that will be finishing up this week is in the Arctic and was conducted on board NOAA Ship Oscar Dyson to collect critical data supporting a long time series involving many scientific partners.

Despite pandemic shutdowns, carbon dioxide and methane surged in 2020 7Apr2021 Read more The global average carbon dioxide level in the atmosphere surged at the fifth-highest rate in NOAA's 63-year record during 2020. Preliminary estimates of the increase in methane levels indicate it may have been the largest annual jump on record. Read more
Climate-driven shifts in deep Lake Michigan water temperatures signal the loss of winter 16Mar2021 Read more Climate change is causing significant impacts on the Great Lakes and the surrounding region. As the largest surface freshwater system in the world, the Great Lakes have an enormous impact, seen and unseen, on the more than 34 million people who live within their collective basin. Because of their unique response to environmental conditions, Earth’s large lakes are considered by scientists as key sentinels of climate change. A long-term study published in Nature Communications today from NOAA reveals a warming trend in deepwater temperatures that foreshadows profound ecological change on the horizon. While less visible than the loss in ice cover and increasing lake surface temperatures, this latest index of climate change adds to the growing evidence of climate change impacts in the region.

NOAA projects 30-percent maximum Great Lakes ice cover for 2021 winter 21Jan2021 Read more NOAA scientists project the maximum Great Lakes ice cover for 2021 will be 30 percent, higher than last year’s maximum of 19.5 percent, but part of a long-term pattern of declining ice cover likely driven by climate change.

New study shows promise of forecasting meteotsunamis 31Mar2021 Read more On the afternoon of April 13, 2018, a large wave of water surged across Lake Michigan and flooded the shores of the picturesque beach town of Ludington, Michigan, damaging homes and boat docks, and flooding intake pipes. Thanks to a local citizen’s photos and other data, NOAA scientists reconstructed the event in models and determined this was the first ever documented meteotsunami in the Great Lakes caused by an atmospheric inertia-gravity wave.

Emissions of a banned ozone-depleting gas are back on the decline 10Feb2021 Read more New analyses of global air measurements show that five years after an unexpected spike in emissions of the banned ozone-depleting chemical chlorofluorocarbon CFC-11, they dropped sharply between 2018 and 2019.
