Sparse and inconsistent coverage of ocean observations makes analysis of climate impacts on ocean physics and marine ecosystems challenging. A new study compares the skills of three high-resolution reanalyses.

A new United Nations report confirms that the recovery of Earth’s protective ozone layer is on track, and that the Montreal Protocol, the international treaty that guides the phase-out of ozone-destroying chemicals, has had the additional benefit of slowing global warming.

Floods and landslides along the U.S. West Coast in January 2023 have happened thanks to an atmospheric river. Satellites can easily spot these rivers over the ocean, observing their structure is harder over land. So NOAA has developed on-the-ground atmospheric river observatories.

While the USGS is the primary agency that monitors volcanic activity in the United States, NOAA oversees safety systems for tsunamis and other volcano-related threats, and studies the impact of volcanic gasses on our global climate. 2022 was a busy year.

A coral rescue near Miami Beach, progress in hurricane forecasting, and the first South Atlantic meridional overturning circulation cruise in three years count among the top stories of 2022.

A new modeling study using Hurricane Harvey as an example suggests that climate change will worsen the severity of flooding by the late 21st century.

On Thursday, January 19, 2023, the Climate Mapping for Resilience and Adaptation (CMRA) Portal team will host a webinar demonstrating the CMRA Portal and Assessment Tool. Anyone interested in learning more is encouraged to register for the webinar.

On December 29, 2022, the United Nations Framework Convention on Climate Change (UNFCCC) submitted its 2022 U.S. Climate Ambitions Report. Coauthored by NOAA Climate Program Office personnel, the report details policies to reach climate targets, and build resilience to climate change impacts.

Unlike Europe, the U.S., and China, the Indo-Gangetic Plain (IGP) has experienced rising air pollution over the last 20 years. New research finds that rising carbon dioxide may slow wind speeds in the region, further worsening air quality.

An environmental DNA sampler, an underwater glider, a saildrone, and some floats are among the instruments highlighted in NOAA’s 12 Days of Instruments.
