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.

Rise of carbon dioxide unabated 4Jun2020 Read more Atmospheric carbon dioxide measured at Mauna Loa Observatory reached a seasonal peak of 417.1 parts per million for 2020 in May, the highest monthly reading ever recorded. Monthly CO2 values at Mauna Loa first breached the 400 ppm threshold in 2014, and are now at levels not experienced by the atmosphere in several million years. Read more
NOAA exploring impact of COVID-19 response on the environment 6May2020 Read more NOAA has launched a wide-ranging research effort to investigate the impact of reduced vehicle traffic, air travel, shipping, manufacturing and other activities on Earth’s atmosphere and oceans due to the response to COVID-19.

Dangerous humid heat extremes occurring decades before expected 8May2020 Read more Climate models project that combinations of heat and humidity could reach deadly thresholds for anyone spending several hours outdoors by the end of the 21st century. However, new NOAA-supported research says these extremes are already happening — decades before anticipated — due to global warming to date. Read more
Warming influence of greenhouse gases continues to rise, NOAA finds 28May2020 Read more NOAA’s Annual Greenhouse Gas Index tracks the concentrations of greenhouse gases being added to the atmosphere principally from human-caused emissions. The AGGI then calculates the heat being added to Earth's atmosphere and oceans as a result. Read more
NOAA teams with United Nations to create locust-tracking application 7May2020 Read more NOAA’s powerful air quality model used to track pollution from wildfires, volcanoes and industrial accidents is now being used to help warn communities across Africa and Asia of what have been called the worst locust swarms in a quarter century.
