NASA-Funded Studies Explain How Climate Is Changing Earth’s Rotation – NASA

Researchers used more than 120 years of data to decipher how melting ice, dwindling groundwater, and rising seas are nudging the planet’s spin axis and lengthening days. Days on Earth are growing slightly longer, and that change is accelerating. The reason is connected to the same mechanisms that also have caused the planet’s axis to … Read more

NASA Satellites Find Snow Didn’t Offset Southwest US Groundwater Loss – NASA

Record snowfall in recent years has not been enough to offset long-term drying conditions and increasing groundwater demands in the U.S. Southwest, according to a new analysis of NASA satellite data. Declining water levels in the Great Salt Lake and Lake Mead have been testaments to a megadrought afflicting western North America since 2000. But … Read more

US, Germany Partnering on Mission to Track Earth’s Water Movement – NASA

The Gravity Recovery and Climate Experiment-Continuity mission will extend a decades-long record of following shifting water masses using gravity measurements. NASA and the German Space Agency at DLR (German Aerospace Center) have agreed to jointly build, launch, and operate a pair of spacecraft that will yield insights into how Earth’s water, ice, and land masses … Read more
