Mosses used to evaluate atmospheric conditions in urban areas
August 17, 2017 04:51 PM - Hokkaido University

Researchers have developed a method to evaluate atmospheric conditions using mosses (bryophytes) in urban areas, a development that could facilitate broader evaluations of atmospheric environments.

Many urban areas face atmospheric problems such as pollution and the heat island effect. With the need to evaluate atmospheric conditions, bioindicators—organisms whose response to environmental changes indicates the health of an ecosystem—have attracted considerable attention. Their merits include being able to evaluate an environment over a wide area at a low cost; detect environmental changes over an extended period; and assess these changes’ effects on the ecosystem. Bryophytes are one such group of plants known to be sensitive to environmental changes, in particular to atmospheric conditions.

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?
