Rising Temperatures Worldwide Change Weather Systems and Distribution of Water Around Globe

Rising temperatures worldwide are changing not only weather systems, but - just as importantly - the distribution of water around the globe, according to a study published today (March 14, 2016) in the journal, "Scientific Reports."

NASA Scientists Study Influence of Tidal Movements on Antarctic Ice Shelves

Ice shelves, the floating extensions of the Antarctic and Greenland ice sheets, are not simply resting on the ocean waters: they rise, fall and bend with the tides. Ultimately, these oceanic motions impact the flow of ice coming from the glaciers that these ice shelves buttress. Ryan Walker and Christine Dow, researchers with the Cryospheric Sciences Laboratory at NASA Goddard Space Flight Center in Greenbelt, Maryland, recently spent more than a month doing fieldwork in Antarctica to study the influence of tidal movements on a small, little-studied ice shelf.

More Effective Way to Use Natural Gas to Reduce Climate-Warming Emissions

Rice University researchers have determined a more effective way to use natural gas to reduce climate-warming emissions would be in the replacement of existing coal-fired power plants and fuel-oil furnaces rather than burning it in cars and buses.

Climate Mitigation Efforts in Energy System Could Lead to Increasing Pressure on Water Resources

A latest study reported in the Environmental Research Letters journal states that the efforts to mitigate climatic conditions might cause pressure on water resources to increase.

New Insights into Physical Processes Controlling Change in Reflectivity of Greenland Ice Sheet

Greenland's snowy surface has been getting darker over the past two decades, absorbing more heat from the sun and increasing snow melt, a new study of satellite data shows.

Carbon Stored in Arctic Soil’s Permafrost Layer Could Accelerate Global Warming

Neil Sturchio, professor and chair of the University of Delaware's Department of Geological Sciences, is exploring how the thawing of permafrost, a subsurface layer of soil that remains mostly frozen throughout the year, affects vegetation and the carbon cycle in the Toolik Lake area of the Alaska's North Slope.

Carbon Fee Needed to Spur Replacement of Carbon Fuels with Clean Energy

A new study reports that current rising temperatures already noticeably load the 'climate dice', with growing practical impacts. As a bottom line, the lead author, Dr James Hansen, argues that a carbon fee is needed to spur replacement of carbon fuels with clean energy.

Sentinel-3A Satellite Helps Study How Carbon Dioxide is Transferred from Atmosphere into Oceans

About a quarter of the carbon dioxide we release each year into the atmosphere ends up in the ocean, but how it happens is still not fully understood. The Sentinel-3A satellite is poised to play an important role in shedding new light on this exchange.

Experts Warn of Impending Public Health Crisis Brought on by Climate Change

Climate change is already having a noticeable impact on the environment and global health. Around the world extreme weather events, increased temperatures, drought, and rising sea levels are all adversely affecting our ability to grow food, access clean water, and work safely outdoors.

Deep-Water Controlled Experiment Aims to Verify Safety of Offshore CO2 Capture and Storage

The world's first 'real world' deep-water controlled experiment to simulate an emission from a submerged carbon dioxide storage reservoir aims to further verify the safety of offshore carbon dioxide (CO2) capture and storage (CCS).
