Climate

New research has found that melting ice sheets provide the surrounding oceans with the essential nutrient silica.

Phytoplankton play a key role in Earth’s climate by removing heat-trapping carbon dioxide from the atmosphere through photosynthesis.

New research shows that changes in the heat flow of the northern Pacific Ocean may have a larger effect on the Arctic climate than previously thought.

When people think of the Arctic, snow, ice and polar bears come to mind. Trees? Not so much. At least not yet.

New research shows that not all corals respond the same to changes in climate.

By mapping the heat escaping from below the Greenland Ice Sheet, a NASA scientist has sharpened our understanding of the dynamics that dominate and shape terrestrial planets.

Scientists have quantified the temperature of Earth's oceans over half a billion years ago by combining fossil data and climate models.

Every 405,000 years, gravitational tugs from Jupiter and Venus slightly elongate Earth's orbit.

The vestiges of lakes long extinct dot the landscape of the American desert west. These fossilized landforms provide clues of how dynamic climate has been over the past few million years.
