The U.S. and Europe are working together on the first 10-year mission to study global warming's effect on the oceans, extending sea level records to nearly 40 years.

Combining gravitational measurements yields a clearer picture of our planet's true shape.

While a growing Greenland glacier may seem like good news, there’s no evidence it means global warming is slowing down.

The Jason-2 mission provided unique insights into ocean currents, sea level rise and climate change for 11 years.

Glaciers shrink and more rock is exposed in satellite images.

Data from the mission show water weight gain across the U.S. Midwest and rapid weight loss from Greenland's melting ice.
