Researchers Explore Effect of Snow on the Amount of Water that Rivers Discharge

New research has shown for the first time that the amount of water flowing through rivers in snow-affected regions depends significantly on how much of the precipitation falls as snowfall.

Greenland Glacial Melt More Dangerous than Previously Believed

Greenland's icy reaches are far more vulnerable to warm ocean waters from climate change than had been thought, according to new research by UC Irvine and NASA glaciologists.

Greenhouse Gas Expert: Control Methane Now to Avoid Environmental Tipping Point in the Future

As the shale gas boom continues, the atmosphere receives more methane, adding to Earth’s greenhouse gas problem.

NASA Hosts Media Teleconference on Stability of West Antarctic Ice Sheet

NASA will host a media teleconference at 9:30 a.m. PDT (12:30 p.m. EDT) Monday, May 12, to discuss new research results on the stability of the West Antarctic Ice Sheet and its potential contribution to future sea level rise.

Melting Ice in East Antarctica could Raise World Sea Levels, Study Finds

The melting of a rather small ice volume on East Antarctica’s shore could trigger a persistent ice discharge into the ocean, resulting in unstoppable sea-level rise for thousands of years to come. This is shown in a study now published in Nature Climate Change by scientists from the Potsdam Institute for Climate Impact Research (PIK). The findings are based on computer simulations of the Antarctic ice flow using improved data of the ground profile underneath the ice sheet.

Study Assesses Environmental Impacts of Biocontainers During Plant Production

Many efforts to reduce the environmental impacts associated with commercial horticulture production have failed to influence the general public. For example, one recent study showed that the use of organic fertilizers offered no significant marketing advantage to producers of floral crops.

Changes in Stratospheric Winds May Not Have a Large Impact on Long-Term Changes in Tropospheric Ozone

New NASA research on natural ozone cycles suggests ozone levels in the lowest part of Earth's atmosphere probably won't be affected much by projected future strengthening of the circulating winds that transport ozone between Earth's two lowest atmospheric layers.

Africa's Congo Rainforest Undergoes Large-Scale Decline in Greenness Due to Drought

A new analysis of NASA satellite data shows Africa's Congo rainforest, the second-largest tropical rainforest in the world, has undergone a large-scale decline in greenness over the past decade.

Arid Ecosystems are a Major Sink for Atmospheric Carbon Dioxide

Researchers led by a Washington State University biologist have found that arid areas, among the biggest ecosystems on the planet, take up an unexpectedly large amount of carbon as levels of carbon dioxide increase in the atmosphere. The findings give scientists a better handle on the earth's carbon budget—how much carbon remains in the atmosphere as CO2, contributing to global warming, and how much gets stored in the land or ocean in other carbon-containing forms.
