Will El Niño push the planet to a new record-high temperature in 2023? Our guest blogger explains what past years tell us.

The Global Monitoring Laboratory’s quest for a reliable, cost-effective way to study Earth’s stratosphere passed a significant milestone on May 17, 2023: A remotely controlled glider, carried to an elevation of 90,000 feet by a weather balloon, returned to its launch location.

The Korea Institute of Ocean Science and Technology hosted NOAA’s Pacific Marine Environmental Laboratory on a research cruise to maintain moorings, part of the Research Moored Array for African-Asian-Australian Monsoon Analysis and Prediction (RAMA).

A new modeling study shows that the emission inventories underestimate volatile organic compound emissions from wildfires when compared to aircraft observations by a factor of 3 to 7.

A new study finds that COVID-19 lockdowns dropped carbon dioxide emissions by rough 20 percent in Salt Lake City, Utah, between March 13 and April 30, 2020.

A new mapping tool may help bring government investment back into communities that have suffered from disinvestment, such as rural communities and communities of color.

On May 9, 2023, scientists aboard the NOAA Ship Ronald H. Brown arrived at their final destination in Reykjavik, Iceland following 55 days at sea, embarking from Brazil. The research team collected over 3,000 samples from the Atlantic’s surface to the seafloor, giving scientists a holistic snapshot of the Atlantic Ocean basin.

A new dataset provides river chemistry and discharge data for 140 U.S. rivers along the West, East, and Gulf of Mexico coasts, based on historical records from the U.S. Geological Survey (USGS) and the U.S. Army Corps of Engineers. This data will support regional ocean biogeochemical modeling and carbon chemistry studies.
