Sargassum spp. is a form of microalgae that negatively impacts coastal and marine ecosystems. The brown tides cause reductions in light, oxygen, and pH, as well as high influxes of nitrogen and phosph ...

The Atlantic Meridional Overturning Circulation (AMOC) is a key component of global climate. A new study shows that, since 1980, AMOC has had periods of strengthening and weakening, although the magnitudes of change are uncertain.

It's too soon to tell whether this winter's double-dip La Niña will become next winter's three-bean salad. But our blogger tells us what's on the menu this spring.

Below-average precipitation across the West led to an expansion of drought.

A new study shows a link between ENSO variations in the Pacific, and anomalies in the Florida Current three months later. This finding may give scientists a three-month lead time to better predict coastal sea level anomalies and possibly extreme weather events.

A new study concludes that, in southwestern North America, 2000–2021 was the driest 22-year period since at least the year 800. The study used tree rings to reconstruct past climates, including periods of megadroughts occurring between 800 and 1600.

Methyl bromide is an ozone-depleting trace gas currently emitted mostly from natural sources. New research suggests a strong correlation between methyl bromide variability and El Niño Southern Oscillation (ENSO) events, particularly ENSO-driven biomass burning.

A new video shows the efforts of NOAA’s Atlantic Oceanographic and Meteorological Laboratory coral researchers to document climate-driven impacts on coral reefs in Dry Tortugas National Park.

The March 2022 climate outlook favors a warmer-than-average month for the eastern/south-central US, a cooler-than-average month for the western/north-central US, and a wetter-than-average month for the Great Lakes.
