Great Lakes water levels at or above average for next 6 months Great Lakes water levels at or above average for next 6 months NOAA and Army Corps issue forecast, consider El Niño potential impact Scientists from NOAA, the U.S. Army Corps of Engineers and Environment Canada have issued a six-month forecast for water levels to be at or above average on Lake Superior, Michigan, Huron, and Erie into spring of 2016. Lake Ontario water levels are expected to remain close to monthly averages. However, the impacts of the anticipated strong El Niño and other atmospheric anomalies on the forecast are difficult to predict. Read more
HFC greenhouse gases: a tale of two (or more) futures HFC greenhouse gases: a tale of two (or more) futures New research projects greenhouse effect from substances that replaced ozone-depleting products A new paper appearing online in Atmospheric Environment coauthored by researchers at NOAA’s Earth System Research Laboratory looked at the climate implications of various proposals for future HFC use that are being discussed this week under the United Nations Montreal Protocol, the global agreement that protects the ozone layer.

Annual Antarctic ozone hole larger and formed later in 2015 Annual Antarctic ozone hole larger and formed later in 2015 The 2015 Antarctic ozone hole area was larger and formed later than in recent years, according to scientists from NOAA and NASA. On Oct. 2, 2015, the ozone hole expanded to its peak of 28.2 million square kilometers (10.9 million square miles), an area larger than the continent of North America. Throughout October, the hole remained large and set many area daily records. Read more
Warming waters a major factor in Gulf of Maine cod collapse Warming waters a major factor in Gulf of Maine cod collapse New study shows how warming complicates fisheries management For centuries, cod was the backbone of New England’s fisheries and a key species in the Gulf of Maine ecosystem. Today, cod stocks in the gulf are on the verge of collapse, hovering at 3-4 percent of sustainable levels. Even setting tighter limits on fishing has failed to slow this rapid decline. Now a new report in Science concludes that rapid warming of Gulf of Maine waters— warming in the last decade faster than in 99 percent of the global ocean —has reduced the capacity of cod to rebound from overfishing, leading to collapse.

NOAA’s Ko Barrett elected vice chair of international climate science panel NOAA’s Ko Barrett elected vice chair of international climate science panel Ko Barrett (left) joins Youba Sokana of Mali and Thelma Krug as IPCC vice chairs The United Nations Intergovernmental Panel on Climate Change (IPCC) elected NOAA’s Ko Barrett to serve as one of three vice chairs for the international body. The IPCC was created to review and assess the most recent scientific, technical, and socio-economic information produced worldwide that is relevant to the understanding of climate change. Read more
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.
