La Niña's fingerprints are on the February climate outlook for the United States, but what other factors are at play?

Along the Mid-Atlantic Coast, sea level changes are growing more extreme. A new study finds these shifts are driven primarily by changing wind patterns.

There is a lot more to the polar vortex than disrupted winds and increased odds for cold weather.

A deep dip in the jet stream brought Arctic air to the South, where it collided with moisture from the Gulf of Mexico.

A recent study found that extensive weakening of the Atlantic Meridional Overturning Circulation occurred in the 2000s, but has paused since the early 2010s due to a tug-of-war between the natural and anthropogenic signals.

As the Los Angeles area faces severe wildland-urban interface fires, scientists are racing to understand the complex mix of pollutants from burning homes, vehicles, and infrastructure that remains largely unknown.

Weather forecasts struggle to predict how much snow will persist or melt. Scientists are addressing this challenge with a more advanced system that better accounts for factors like snow grain size, shape, and impurities like dust or soot.

A new study adds to the growing evidence that cloud feedback likely amplifies warming, rather than reducing it. Cloud impacts in the tropical Pacific and Atlantic Oceans are 71% higher than previously thought.

Why no one should expect a perfect match between what happens during a La Niña winter and the expected La Niña pattern. But knowing whether it may be a El Niño or La Niña winter is still useful!

A deep look at the water in the Great Lakes shows that winters are about 14 days shorter than they were in 1995. This finding marks the first use of subsurface temperature readings to determine how climate change may affect seasons in and around the Great Lakes.
