Little-Understood Rivers Flowing on Top of Ice Sheet Also Contribute to Rising Sea Levels

As the largest single chunk of melting snow and ice in the world, the massive ice sheet that covers about 80 percent of Greenland is recognized as the biggest potential contributor to rising sea levels due to glacial meltwater.

Economic Damage Caused Carbon Dioxide Emissions Could Be Six Times Higher

The economic damage caused by a ton of carbon dioxide emissions - often referred to as the "social cost" of carbon - could actually be six times higher than the value that the United States now uses to guide current energy regulations, and possibly future mitigation policies, Stanford scientists say.

Warming in Western U.S. Mountains Not as Large as Previously Supposed

In a recent study, University of Montana and Montana Climate Office researcher Jared Oyler found that while the western U.S. has warmed, recently observed warming in the mountains of the western U.S. likely is not as large as previously supposed.

Global Warming May Cause Decline in Worldwide Wheat Production

Future global wheat harvest is likely to be reduced by six per cent per each degree Celsius of local temperature increase if no adaptation takes place. Worldwide this would correspond to 42 million tons of yield reduction, which equals a quarter of current global wheat trade.

Andaman Sea's Corals Protected from Heat Stress by Cool Deep-Water

1991, 1995, 2003, 2010 - again and again, increased water temperatures lead to bleaching with fatal consequences for stony corals in the Andaman Sea. These animals are highly susceptible to changes in water temperatures. Even a small temperature rise damages the symbiotic algae living in a cell layer of the corals causing their expulsion by the coral host.

Fossil Fuel Reserves Can Limit Global Warming If Not Used by 2050

A third of oil reserves, half of gas reserves and over 80% of current coal reserves globally should remain in the ground and not be used before 2050 if global warming is to stay below the 2°C target agreed by policy makers, according to new research by the UCL Institute for Sustainable Resources.

Strong Pacific Trade Winds May Be Helping Prevent Rise in Global Temperatures

New research indicates that shifts in Pacific trade winds played a key role in twentieth century climate variation, a sign that they may again be influencing global temperatures.

Rayleigh Jet Technique Proves to be Best for Marine Cloud Brightening

Marine Cloud Brightening is a reversible geoengineering method proposed to mitigate rising global temperatures. It relies on propelling a fine mist of salt particles high into the atmosphere to increase the albedo of clouds - the amount of sunlight they reflect back into space. This would then reduce temperatures on the surface, as less sunlight reaches the Earth.

Paleocene-Eocene Thermal Maximum Could Provide Clues to Future of Modern Climate Change

The rate at which carbon emissions warmed Earth's climate almost 56 million years ago resembles modern, human-caused global warming much more than previously believed, but involved two pulses of carbon to the atmosphere, researchers have found.

Asking Precise Questions May Help Understand Relationship Between Global Warming and Extreme Weather

Extreme climate and weather events such as record high temperatures, intense downpours and severe storm surges are becoming more common in many parts of the world. But because high-quality weather records go back only about 100 years, most scientists have been reluctant to say if global warming affected particular extreme events.
