It is a telling illustration of the precarious state of United States dams that the near-collapse in February 2017 of Oroville Dam, the nation’s tallest, occurred in California, considered one of the nation’s leading states in dam safety management.

The El Niño-Southern Oscillation has been responsible for widespread, simultaneous crop failures in recent history, according to a new study from researchers at Columbia University’s International Research Institute for Climate and Society, the International Food Policy Research Institute (IFPRI) and other partners. 

Fluctuations in the masses of the world’s largest ice sheets carry important consequences for future sea level rise, but understanding the complicated interplay of atmospheric conditions, snowfall input and melting processes has never been easy to measure due to the sheer size and remoteness inherent to glacial landscapes.

A new report outlines 12 major areas of climate change risk facing Canada from a national perspective, all of which could involve significant losses, damages or disruptions over the next two decades.

NOAA’s story map takes you inside tornado alley to NOAA’s Norman, Okla., campus.

An unprecedented belt of brown algae stretches from West Africa to the Gulf of Mexico—and it’s likely here to stay.

Planting more vegetation, using reflective materials on hard surfaces and installing green roofs on buildings can help cool potentially deadly urban heat islands -- a phenomenon that exists in nearly all large cities -- a new study from Portland State University shows.

The U.S. Forest Service’s Gila National Forest reported four naturally caused fires on July 4, 2019, and three of them generated enough smoke to be seen from space by satellite.

Fish die-offs in Wisconsin lakes are expected to double by mid-century and quadruple by 2100 due to warmer summer temperatures, according to a study published today in the journal Nature Climate Change.

The near-surface southerly wind is a key feature of East Asian summer monsoon (EASM) circulation, and a stronger EASM circulation leads to a northward shift of East Asian rainfall. Almost all climate models show an enhanced EASM circulation in a warmer climate, and previous studies attributed the enhanced EASM to the enhanced zonal land-sea thermal contrast.
