A new NOAA study finds that reducing particulate air pollution in Europe and North America has contributed to an increase in the number of tropical cyclones in the North Atlantic basin, and a decrease in the number of these storms in the Southern Hemisphere.

A newly published study suggests a major sea-surface freshening during the mid-20th century, and a southward migration of the Intertropical Convergence Zone, affecting tropical rainfall patterns.

NOAA, the National Integrated Heat Health Information System, and the Department of Health and Human Services’ Office of Climate Change and Health Equity have launched a new public information series called the Climate and Health Outlook. Melding weather forecasts and health resources, the Outlook aims to reduce high-heat health risks and save lives.

As the ENSO blog turns 8, we're looking at the present nobody wanted: a La Niña three-peat looks increasingly likely this winter.

Two NOAA hurricane experts explain why it’s still so hard to say whether global warming to date has affected the number or intensity of Atlantic hurricanes.

The Argo program started in 1998 when scientists proposed a global array of autonomous floats to take temperature and salinity measurements of the world’s ocean. The program has won an award “for innovation in large-scale autonomous observations in oceanography with global impacts in marine and climate science and technology.”

The National Integrated Heat Health Information System (NIHHIS) Interagency Communications Group will host a heat season awareness social media campaign during the week of May 16, 2022. Themes will cover heat-related illness, heat vulnerability, outdoor and indoor workers, exercise in hot conditions, and preparedness.

A new study finds that projected future warming will result in El Niño events that grow at a faster rate, persist longer over the eastern and far eastern Pacific, and have stronger and distinct remote impacts.

April was a little cooler than average for the contiguous United States, and it was a month for extreme events, with tornadoes, blizzards, and wildfires.

A new study has found a link between red tides and dead zones along Florida’s west coast. When harmful algal blooms strike in early summer and persist into autumn, low-oxygen dead zones are also likely.
