News & Research Highlights

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.

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.

After a year and a half of coordination and planning, the Hurricane and Ocean Testbed (HOT) has been successfully launched in the newly designed William M. Lapenta Laboratory. This testbed establishes a physical and virtual collaboration space for researchers and forecasters.

Understanding how dust moves through the atmosphere will be important as scientists try to predict how climate change will influence weather patterns. New research suggests that dust particles spur the formation of cirrus clouds.

In the newly released IPCC Climate Change 2022 Impacts Report, authors lay out a clear case for a major turnaround that will better integrate the world’s economic and environmental systems for a sustainable future.

The Atlantic Meridional Overturning Circulation (AMOC) is a significant component of Earth’s climate system, so realistic simulation of the AMOC is key to climate prediction. A new study indicates sea-surface salinity plays an important role in realistic AMOC simulation.

“We could see it unfolding right out the window. We knew it was moving into a highly populated area, and we knew people who lived there.” A new story map describes Marshall Fire from the perspective of National Weather Service meteorologists.
