An annual analysis of air samples collected at remote sites around the globe that is tracking a continued decline in the atmospheric concentration of ozone-depleting substances shows the threat to the ozone layer receding below a significant milestone in 2022, NOAA scientists have announced.
Large wildfires and severe heat events are happening more often at the same time, worsening air pollution across the western United States, according to a new study led by Washington State University, with CIRES and NOAA’s Global Systems Laboratory.
Spectacular footage from inside a hurricane; a major ocean mapping milestone; new insights on the continued impacts of climate change, and much more -- 2021 was a busy year for NOAA Research. As the year draws to a close, we’re taking a look back at a few of our biggest research stories of the last 12 months.
For nearly 50 years, NOAA’s Barrow Atmospheric Baseline Observatory has provided a window on the world, producing a record of changes that have a profound global reach.
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.
In late February, as the Southern Plains and Gulf Coast suffered through an unusually strong blast of wintry weather, weather talk turned to the polar vortex and the possibility that the extreme cold was yet another example of weather-gone-wild due to global warming.
From predicting smoke movement from massive wildfires, to investigating how marine life is responding to a quieter ocean, 2020 was a big year for NOAA science. As this unprecedented year draws to a close, we’re looking back at some of our biggest research endeavors in 2020. Here are 5 of our most-read stories from the last year.
A NOAA study published in Nature Geosciences takes a new look at faint, old smoke and finds that it is just as important an influence on the climate as the thick plumes produced by active fires.
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.
Picture a calm, sunny day at a tropical beach. You look out at the ocean and in the distance a flotilla of small white clouds sails close to the waves. It’s ideal weather and typical of many days in the tropical Atlantic. However, scientists don’t fully understand how these ubiquitous clouds (a type of “shallow convective cloud”) form and impact the ocean, and it represents one of the largest uncertainties in predicting climate change.
