Latest Gravity Recovery and Climate Experiment Stories
Using satellite data, UC Irvine and NASA hydrologists have found that groundwater beneath northern India has been receding by as much as 1 foot per year over the past decade â€“ and they believe human consumption is almost entirely to blame.
A NASA-led research team has used satellite data to make the most precise measurements to date of changes in the mass of mountain glaciers in the Gulf of Alaska, a region expected to be a significant contributor to global sea level rise over the next 50-100 years.
Scientists have detected an ongoing reversal in Arctic Ocean circulation triggered by atmospheric conditions. The results suggest not all the large changes seen in Arctic climate in recent years are a result of long-term trends associated with global warming.
Just a few years ago, the world's climate scientists predicted that Greenland wouldn't have much impact at all on sea level in the coming decades. But recent measurements show that Greenland's ice cap is melting much faster than expected.
Recent space observations of freshwater storage by the Gravity Recovery and Climate Experiment (Grace) are providing a new picture of how Earth's most precious natural resource is distributed globally and how it is changing.
For the first time NASA scientists have analyzed data from direct, detailed satellite measurements to show that ice losses now far surpass ice gains in the shrinking Greenland ice sheet.
A new analysis of data from twin satellites has revealed that the melting of Greenland's ice sheet has increased dramatically in the past few years, with much of the loss occurring primarily along one shoreline potentially affecting weather in Western Europe.
For the first time, NASA scientists using space-based measurements have directly monitored and measured the complete cycle of water movement for an entire continent.
Sea level isn't, well, level. Nor is the rate by which sea level has been rising over the past few decades, but the trend is clearly up. Rising seas have the potential to affect billions of people around the globe, not just those living near coastlines.
In the first direct, comprehensive mass survey of the entire Greenland ice sheet, scientists using data from the NASA/German Aerospace Center Gravity Recovery and Climate Experiment (Grace) have measured a significant decrease in the mass of the Greenland ice cap. Grace is a satellite mission that measures movement in Earth's mass.
