As pollution increases, world falls further behind climate targets

November 19, 2024

At current rates, the Global Carbon Budget estimates, there’s a 50 percent likelihood that global average air temperatures will regularly exceed the 1.5-degree Celsius target (2.7 degrees Fahrenheit) by 2031.

New NOAA research predicts an increase in active Atlantic hurricane seasons

November 19, 2024

A newly published study projects an increase in the variability of Atlantic tropical cyclone activity, leading to more active and inactive hurricane seasons and less near-normal seasons.

Study: heat, not lack of precipitation, is driving western U. S. droughts

November 12, 2024

During the 2020-2022 drought, evaporation accounted for 61 percent of the drought’s severity, while reduced precipitation only accounted for only 39 percent.

Mapping flash drought patterns across the U. S.

November 12, 2024

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 disrupt ocean circulation and nutrient distribution in the Gulf of Alaska

November 12, 2024

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.

Effect of regional anthropogenic aerosols on tropical cyclone frequency of occurrence

November 5, 2024

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

Study reveals acceleration in Pacific upper-ocean circulation over past 30 years, impacting global weather patterns

November 5, 2024

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.

Researchers achieve long-term predictions of coastal sea level rise using machine learning

November 5, 2024

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.

Balancing act: why Earth's hemispheres reflect sunlight equally despite pollution, cloud, and climate differences

November 5, 2024

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.

Applications now open nationwide for community-led heat-monitoring campaigns

November 5, 2024

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.
