NASA Tracks the Future of Asia’s Glaciers

/ activist360 / Leave a comment
Asia’s high mountains are a crucial freshwater source to one-seventh of the world’s population. Snow and glaciers in these mountains contain the largest volume of freshwater outside of Earth’s polar ice sheets, leading hydrologists to nickname this region the “third pole.”
Rapid changes in the region’s climate, however, are affecting glacier flows and snowmelt. Local people are already modifying their land-use practices in response to the changing supply, and the region’s ecology is transforming. Scientists estimate that by 2100, these glaciers could be up to 75% smaller in volume.
NASA’s satellites observe and measure snow and ice cover remotely with multiple types of sensors. This allows scientists to create an authoritative estimate of the water budget of this region and a set of products local policy makers can use in responding to hazards and planning for a changing water supply.

NASA Has Eyes On The Atlantic Hurricane Season

/ activist360 / Leave a comment
NASA has a unique and important view of hurricanes around the planet. Satellites and aircraft watch as storms form, travel across the ocean and sometimes, make landfall. After the hurricanes have passed, the satellites and aircraft see the aftermath of hurricanes, from downed forests to mass power loss.
