Study: In 2016’s record Arctic warmth, a glimpse of the future Study: In 2016’s record Arctic warmth, a glimpse of the future An analysis of the record heat afflicting the Arctic in 2016 finds that it couldn't have happened without climate change. Read more
Unique collaboration works to extend sea ice prediction from days to decades Unique collaboration works to extend sea ice prediction from days to decades For more than two decades, Elizabeth Hunke has worked at the Department of Energy’s Los Alamos National Laboratory to design, create and improve a model used to predict sea ice extent, thickness and movement in both the Arctic and Antarctica. From the beginning, Hunke understood that collaboration was the key to improving this model. At a time when sea ice prediction is needed more than ever, NOAA, the Navy and other agencies are working together to extend sea ice prediction from days to decades. Read more

Atmospheric Rivers: What are they and how does NOAA study them? 11Jan2023 Read more You may have heard of atmospheric rivers in the news lately due to the intense rainfall and flooding along the U.S. West Coast. These naturally occurring air currents can bring both severe disruption and great benefit through the heavy rain and mountain snows that contribute to regional water supply. NOAA studies atmospheric rivers to improve forecasting capabilities as well as to improve our understanding of atmospheric river impacts on communities and the physical environment. Read more
One facility makes a big contribution to Salt Lake’s winter brown cloud 25Jan2023 Read more The 2.4 million people who live along Utah’s Wasatch Front experience some of the most severe winter particulate matter air pollution in the nation. Now, analysis of measurements taken during NOAA research flights in 2017 indicates that emissions from a single source, a magnesium refinery, may be responsible for a significant fraction of the fine particles that form the dense winter brown clouds that hang over Salt Lake City.

When volcanoes roar: protecting the public and tracking long-term climate impacts 5Jan2023 Read more 2022 was a busy year for volcanic eruptions with Hawaii's Mauna Loa and Kilaeau erupting simultaneously, along with Mount Semeru, Indonesia and the Hunga undersea volcano in Tonga. While the United States Geological Survey is the primary agency that monitors volcanic activity in the United States, the National Oceanic and Atmospheric Administration (NOAA) oversees safety systems for tsunamis and other volcano-related threats, as well as studies the impact of volcanic gasses on our global climate.
