New NOAA-supported West Coast studies to look at models for sustaining America's fishing industry New NOAA-supported West Coast studies to look at models for sustaining America's fishing industry The “locavore” movement helps America’s farmers. Could it also help our fishing industry? Two new NOAA Sea Grant studies will look at how new business models, based on the success of community supported agriculture, could benefit fishing communities in Washington, Oregon, and California.

Decades of research on Great Lakes ice cover reveal trends Decades of research on Great Lakes ice cover reveal trends NOAA’s Great Lakes Environmental Research Lab has monitored ice cover on the lakes for decades. Its measurements have documented wide variations from winter to winter and made possible discoveries about climate links to variation in ice cover. Read more
Asian emissions can increase ground-level ozone pollution in U.S. West Asian emissions can increase ground-level ozone pollution in U.S. West Springtime air pollution from Asia, swept across the Pacific Ocean on winds, can contribute to episodes of high surface ozone pollution in the western United States.

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
Carbon dioxide peaks near 420 parts per million at Mauna Loa observatory 7Jun2021 Read more In May, NOAA's measurements at the Mauna Loa observatory averaged 419.13 parts per million. Scientists at Scripps calculated a monthly average of 418.92 ppm. It's the highest level since accurate measurements began 63 years ago. Read more
NOAA index tracks how greenhouse gas pollution amplified global warming in 2020 24May2021 Read more The annual analysis of samples collected by NOAA’s Global Greenhouse Gas Reference Network provides an updated measure of the excess heat trapped in the atmosphere by greenhouse gas pollution.

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
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.
