El Niño-Southern Oscillation contributes to global climate variability, with significant impacts on the North American continent. New research uses a combination of paleoclimatic and instrumental data to more reliably quantify the impacts of variability in this interconnected system.

Higher temperatures and higher precipitation can create more habitat for mosquitoes and ticks, raising the risk of illnesses such as Lyme disease and West Nile virus. In response, the Centers for Disease Control and Prevention has developed “A National Public Health Framework for the Prevention and Control of Vector-Borne Diseases in Humans.”

Understanding volcanoes is essential to fully understanding the El Niño-Southern Oscillation (ENSO) and its effects on climate. A newly published study revisits the link between ENSO and volcanic activity, in light of newer data.

Drought can worsen ozone pollution in some parts of the United States. Although research uncovered no increase in ozone when drought conditions strike the U.S. West, it uncovered an increase in summertime ozone during drought in the Southeast.

David Herring, head of the NOAA Climate Program Office’s Communication, Education, and Engagement Division, will speak at the U.S. Conference of Mayors Leadership meeting on March 4, 2022.

As rising carbon emissions increase ocean acidity, alkaline river runoff might slow acidification. New research along the northern coast of the Gulf of Mexico indicates a link between river runoff and ocean chemistry.

The United States is expected to experience as much sea level rise by the year 2050 as it witnessed in the previous hundred years. The report projects sea levels along the coastline will rise an additional 10-12 inches in the next 30 years, with specific amounts varying regionally, mainly due to land height changes.

Rapid climate change has affected salmon populations—and the people who depend on them—for decades. NOAA Fisheries and the NOAA Pacific Marine Environment Laboratory are collaborating with an international team of scientists in an expedition to close gaps in understanding about salmon.

The year-long MOSAiC expedition collected unprecedented environmental data from the Central Arctic Ocean. The research team has just published three overview articles on the MOSAiC atmosphere, snow and sea ice, and ocean.

A newly released video highlights how climate change is affecting marine sanctuaries, and how NOAA is addressing climate change impacts in these spectacular places.
