New study validates East Antarctic ice sheet should remain stable even if western ice sheet melts
August 17, 2017 04:37 PM - Indiana University

A new study from Indiana University-Purdue University Indianapolis validates that the central core of the East Antarctic ice sheet should remain stable even if the West Antarctic ice sheet melts.

The study's findings are significant, given that some predict the West Antarctic ice sheet could melt quickly due to global warming.

NASA Sees Potential Tropical Depression 9 Form East of Lesser Antilles
August 17, 2017 04:31 PM - NASA / Goddard Space Flight Center

NOAA's GOES-East Satellite spotted potential Tropical Depression 9 organizing east of the Lesser Antilles.

At 10:45 a.m. EDT (1445 UTC) on Aug. 13 NOAA's GOES-East satellite captured a visible image of potential Tropical Depression 9. The satellite imagery showed the circulation of the low pressure area was becoming better defined and that a cluster of strong convection has formed west of the center.

NOAA manages the GOES series of satellites, and NASA uses the satellite data to create images and animations. The image was created by the NASA/NOAA GOES Project at NASA's Goddard Space Flight Center in Greenbelt, Maryland.

Satellites Show Hurricane Gert Being Affected by Wind Shear

NASA’s Aqua satellite and NOAA's GOES-East satellite provided an infrared and visible look at Atlantic Hurricane Gert. Both images showed the storm was being affected by wind shear and had become elongated.

Investigating the Enigma of Clouds and Climate Change
August 17, 2017 08:30 AM - Yale Environment 360

Clouds perform an important function in cooling the planet as they reflect solar energy back into space. Yet clouds also intensify warming by trapping the planet’s heat and radiating it back to earth. As fossil fuel emissions continue to warm the planet, how will this dual role played by clouds change, and will clouds ultimately exacerbate or moderate global warming?

Freeze-dried foam soaks up carbon dioxide
August 16, 2017 04:55 PM - Rice University

Rice University materials scientists have created a light foam from two-dimensional sheets of hexagonal-boron nitride (h-BN) that absorbs carbon dioxide.

They discovered freeze-drying h-BN turned it into a macro-scale foam that disintegrates in liquids. But adding a bit of polyvinyl alcohol (PVA) into the mix transformed it into a far more robust and useful material.

The foam is highly porous and its properties can be tuned for use in air filters and as gas absorption materials, according to researchers in the Rice lab of materials scientist Pulickel Ajayan.

Their work appears in the American Chemical Society journal ACS Nano.

Urban floods intensifying, countryside drying up
