Tropical storms and hurricanes are driven by energy and momentum derived from warm ocean waters of at least 26.5°C. The warmer the ocean, the more energy is available to the storm, and the more intense it is likely to become. Ordinarily, these storms lose energy after making landfall, as they move beyond the ocean as…
How deep is that icy blue water on Greenland’s ice sheet? Dr. Allen Pope, of the National Snow and Ice Data Center, is using data from the NASA/USGS Landsat 8 satellite to find out. In this video, Dr. Pope shares what he sees when he looks at a Landsat image of the Greenland ice sheet…
GRACE consists of twin co-orbiting satellites that fly in a near polar orbit separated by a distance of 220 km. GRACE precisely measures the distance between the two spacecraft in order to make detailed measurements of the Earth’s gravitational field. Since its launch in 2002, GRACE has provided a continuous record of changes in the…
Oceanographer Josh Willis from NASA’s Jet Propulsion Laboratory narrates this video about the causes of sea level rise and how sea level has changed over the last two decades as observed by the Jason series of satellite missions.

Project Sunroof is mapping the planet’s solar potential, one rooftop at a time. Project Sunroof uses information that’s in Google Maps to figure out how much sun falls on a roof and takes into account stuff like the angle of the roof, the weather, and obstructions like trees and chimneys. Then it uses those measurements…
According to a new study, sea level rise of several meters might happen faster then previously thought. Based on data from past climate changes, when sea level rose to +5–9 m, including the occurrence of extreme storms – during a time when temperatures were less than 1 ◦C warmer than today, experts warn of similar…
