5 ways NOAA scientists are answering big questions about climate change

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.

New study shows promise of forecasting meteotsunamis

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.

Climate-driven shifts in deep Lake Michigan water temperatures signal the loss of winter

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. 

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
