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.

A warm pool in the Indo-Pacific Ocean has almost doubled in size, changing global rainfall patterns A warm pool in the Indo-Pacific Ocean has almost doubled in size, changing global rainfall patterns Due to human-caused climate change, our planet’s ocean has been heating up at a rate of 0.6 degrees C (0.11 degrees F) per decade over the past century. But this warming isn’t uniform. Read more
US methane “hotspot” is snapshot of local pollution US methane “hotspot” is snapshot of local pollution The giant methane cloud spotted by satellite over the U.S. Southwest that made national headlines in 2014 wasn’t a persistent, undiscovered “hotspot” as first thought, but the result of a nightly atmospheric condition and topography that trapped industrial and natural emissions of the potent greenhouse gas near the ground in the basin overnight, according to new research published in the journal Elementa by CIRES and NOAA.

NOAA’s ocean exploration advisory board forges ahead with new members NOAA’s ocean exploration advisory board forges ahead with new members On December 10, 2020, the NOAA Ocean Exploration Advisory Board (OEAB) will hold its 18th meeting. With the June 2020 release of the National Strategy for Mapping, Exploring, and Characterizing the U.S. Exclusive Economic Zone, ocean exploration is in the spotlight. During the December meeting, the OEAB will make recommendations to the administration for advancing ocean exploration over the next 6-12 months. It will do so with five new members on board.

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.
