A new study links the record-low Arctic sea ice extent in 2012 tropical sea surface temperatures. The study finds that back-to-back La Niña events in 2010 and 2011, followed by a marginal El Niño may have affected Arctic sea ice.

An annual survey is underway to provide fisheries and oceanographic data to support sustainable management of the fast-changing Bering Sea. These surveys help decision makers better understand the impacts of events such as sea ice loss.

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.

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.

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.

New climate modeling indicates an increase in flash flooding across most of the United States. Heavy rainfall events will likely cause more frequent and stronger flash floods by the end of the century.
