New study finds Alaskans familiar with ocean acidification, not aware of risks to fisheries New study finds Alaskans familiar with ocean acidification, not aware of risks to fisheries New research published in Marine Policy from the first Alaska-focused study on public understanding and awareness of ocean acidification risk shows that Alaskans are three times more aware of ocean acidification than Americans in general. However, Alaskans have difficulty seeing ocean acidification as an immediate risk, and the direct risks to Alaska’s fisheries are still not well understood. The research, “Gauging perceptions of ocean acidification in Alaska,” can be read online. Read more
Shock of Indian Ocean tsunami fuels decade of research progress Shock of Indian Ocean tsunami fuels decade of research progress New generation of warning products increase tsunami preparedness Nearly 10 years ago, the world woke the day after Christmas to news of the most deadly tsunami in recorded history. Triggered by an underwater earthquake, the Indian Ocean tsunami of December 26, 2004, took the lives of nearly 240,000 unwarned people in four hours and displaced 1.7 million people in over 14 countries. Over the last 10 years, NOAA scientists have worked to dramatically improve tsunami warning and forecasts that can and have helped the nation and the world. Read more
NOAA and partners document surge in Great Lakes water levels NOAA and partners document surge in Great Lakes water levels Levels expected to stay above-average through winter and spring of 2015 Scientists at the Army Corps of Engineers, Environment Canada, and NOAA recently documented a record-setting surge in water levels on Lakes Superior and Michigan-Huron that began in January 2013, and has continued through November 2014. The United States and Canadian federal agencies expect water levels to stay near or above average on all of the Great Lakes over the next six months. Read more
Researchers offer new insights into predicting future droughts in California Researchers offer new insights into predicting future droughts in California Natural cycles, sea surface temperatures found to be main drivers in ongoing event According to a new NOAA-sponsored study, natural oceanic and atmospheric patterns are the primary drivers behind California's ongoing drought. A high pressure ridge off the West Coast (typical of historic droughts) prevailed for three winters, blocking important wet season storms, with ocean surface temperature patterns making such a ridge much more likely. Typically, the winter season in California provides the state with a majority of its annual snow and rainfall that replenish water supplies for communities and ecosystems. Read more
NOAA scientists to share research and resiliency tools at international climate meeting NOAA scientists to share research and resiliency tools at international climate meeting Presentations by Amanda McCarty and Libby Jewett to be web-streamed live from Lima, Peru Several NOAA scientists will present information on climate research and new tools to build greater resiliency to climate change at a meeting on the United Nations Framework Convention on Climate Change in Lima, Peru, that will run from December 1-12.

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.

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.

5 ways NOAA scientists are answering big questions about climate change 20Apr2021 Read more From warmer ocean temperatures to longer and more intense droughts and heat waves, climate change is affecting our entire planet. Scientists at NOAA have long worked to track, understand and predict how climate change is progressing and impacting ecosystems, communities and economies. Read more
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.
