Drought data over 2001-2021 suggest that in the western United States, low rainfall drove droughts but in the central and eastern U.S., low soil moisture and high evaporation played a bigger role.

Marine heatwaves create high-pressure atmospheric conditions that weaken coastal circulation in the Gulf of Alaska, reducing the formation of the eddies essential for supporting marine life.

Released in 2023, the Fifth National Climate Assessment (NCA5) includes an Art × Climate gallery. This watercolor by Amalija_M was created to inspire greater appreciation of marine life.

October 2024 was record dry across many climate stations in the eastern United States, leading to increasing drought and wildfire concerns.

Fed by Helene's moisture, a predecessor rain event in the Southern Appalachians prior to the hurricane's landfall caused record rainfall and flooding in September 2024. Increased humidity due to global warming likely boosted rainfall totals.

While aerosol changes have varied across regions since 1980, these regional differences have influenced global tropical cyclone activity in distinct ways over recent decades.

A new study reveals significant acceleration in the upper-ocean circulation of the equatorial Pacific over the past 30 years, primarily driven by intensified atmospheric winds.

Recurring sea level patterns to show it’s possible to predict large-scale sea level patterns and even anticipate coastal variations up to 8 years in advance.

The Northern Hemisphere’s aerosols and land reflect more sunlight, balanced by the Southern Hemisphere’s low- and mid-level clouds. Both hemispheres are darkening, but it’s unclear if this change is happening equally.

The Center for Collaborative Heat Monitoring opened applications for communities across the U.S. to monitor and evaluate factors influencing local heat risk. The effort is funded through the Inflation Reduction Act.
