New study: Dust, warming portend dry future for the Colorado River New study: Dust, warming portend dry future for the Colorado River Land management efforts could help protect snowpacks, water from a warmer future Reducing the amount of desert dust swept onto snowy Rocky Mountain peaks could help Western water managers deal with the challenges of a warmer future, according to a new study led by researchers at NOAA’s Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado Boulder.

New study: Rising temperatures challenge Salt Lake City’s water supply New study: Rising temperatures challenge Salt Lake City’s water supply Sensitivity study helps the city, others in the Intermountain West, plan for the future In an example of the challenges water-strapped Western cities will face in a warming world, new research shows that every degree Fahrenheit of warming in the Salt Lake City region could mean a 1.8 to 6.5 percent drop in the annual flow of streams that provide water to the city.

NOAA Sea Grant awards $1.8 million to Sandy-hit states to better understand public response to coastal storm threats NOAA Sea Grant awards $1.8 million to Sandy-hit states to better understand public response to coastal storm threats NOAA Sea Grant this month announced $1.8 million in grant awards to Connecticut, New York, and New Jersey to enhance the American public’s ability to effectively plan, prepare and respond to natural disasters when they strike—particularly for major storms like Sandy, which resulted in 140 fatalities last year.

Encouraging information from this year’s observations of the Antarctic ozone hole Encouraging information from this year’s observations of the Antarctic ozone hole For nearly 50 years, scientists with NOAA have launched high-altitude balloons from the South Pole, to understand why a hole was forming in the protective ozone layer high in the atmosphere. Now, organizations around the world track the infamous ozone hole through these ballon-sondes, satellite measurements and ground instruments. Read more
Water vapor in the upper atmosphere amplifies global warming, says new study Water vapor in the upper atmosphere amplifies global warming, says new study A new study shows that water vapor high in the sky and the temperature at the Earth’s surface are linked in a “feedback loop” that further warms our climate. Published today, this study gives the first estimate of the size of the feedback’s effect, which may help researchers improve modeling to better understand climate change. Read more
NOAA, Aquarium of the Pacific report on the future of American ocean exploration NOAA, Aquarium of the Pacific report on the future of American ocean exploration More than 100 explorers, scientists, government officials, academics, and industry leaders who attended the inaugural ‘Ocean Exploration 2020: A National Forum,’ in July, have proposed the future of American ocean exploration. NOAA and the Aquarium of the Pacific in Long Beach, Calif., hosted the Forum, and released a report this week examining the future of ocean exploration through a coordinated federal effort involving multiple agencies in collaboration with the private sector.

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.
