Satellite data reveal that warmer Atlantic waters are intruding on Arctic sea ice. The warm waters are impeding sea ice regrowth in winter.

The world's biggest Iceberg - named A-76- cracked off of Antarctica in late May.

Clouds in the sky can sometimes look like ocean waves. These photographic clouds are called Kelvin-Helmholtz clouds, and occasionally also go by the name billow clouds or shear-gravity clouds.

The complex interplay among many factors - African monsoons, ocean temperatures, wind shear, El Niño and La Niña – that go into predicting hurricane season.

NOAA is predicting a busier-than-usual hurricane season for 2021. Although hurricane season officially starts June 1, subtropical storm Ana - which formed early Saturday off the coast of Bermuda - has already become the season’s 1st named storm.

New research shows that a small dinosaur called Shuvuuia deserti, which lived in the deserts of what's now Mongolia, had exceptional night vision and hearing, similar to modern day owls and other night predators.

On May 18, 1980, Mount St. Helens erupted in a deadly explosion, collapsing one side of the mountain and killing 57 people.

Scientists have found a surprising modern-day symbiosis between 2 undersea animals, which had been gone from the fossil record for 270 million years.

We think of earthly life as evolving from the sea. But newly discovered microscopic "ball" fossils - found in ancient lake sediments in Scotland - suggest that evolution from single-celled to multicellular organisms might have occurred in lakes.

Climatologists at NOAA have released updated climate "normals." They explain what "normal" means, how our U.S. climate normals have changed, and how to best make sense of them.
