How Radiative Fluxes Are Affected by Cloud and Particle Characteristics

Apr. 17, 2015 — Climate models calculate a changing mix of clouds and emissions that interact with solar energy. To narrow the broad range of possible answers from a climate model, researchers analyzed the effect of ... read more

New Method Relates Greenland Ice Sheet Changes to Sea-Level Rise

Apr. 14, 2015 — Early schemes to model the Greenland and Antarctic ice sheets and their impact on sea levels failed to accurately account for changes caused by snowfall and snow melt. These changes depend on ice ... read more

Mar. 16, 2015 — Researchers have discovered two seafloor gateways that could allow warm ocean water to reach the base of Totten Glacier, East Antarctica's largest and most rapidly thinning glacier. The ... read more

Past Warming Increased Snowfall on Antarctica, Affecting Global Sea Level

Mar. 16, 2015 — A new study confirms that snowfall in Antarctica will increase significantly as the planet warms, offsetting future sea level rise from other sources -- but the effect will not be nearly as strong as ... read more

Mar. 10, 2015 — Fresh off the recent successful deployment of its 20-foot (6-meter) reflector antenna and associated boom arm, NASA's new Soil Moisture Active Passive (SMAP) observatory has successfully ... read more

Friction Means Antarctic Glaciers More Sensitive to Climate Change Than We Thought

Mar. 10, 2015 — A new study finds that incorporating Coulomb friction into computer models increases the sensitivity of Antarctic ice sheets to temperature perturbations driven by climate ... read more

Mar. 5, 2015 — When you walk on the beach, the sand supports your weight like a solid. What happens to the forces between the sand grains when you step on them to keep you from sinking? Researchers have developed a ... read more

Mar. 6, 2015 — Researchers measure underwater noise in Alaskan and Antarctic fjords and find them to be the noisiest places in the ocean. This leads researchers to ask how animals such as whales and seals use the ... read more

Mar. 3, 2015 — Historic submarine and modern satellite records show that average ice thickness in the central Arctic Ocean dropped by 65 percent from 1975 to 2012. September ice thickness, when the ice cover is at ... read more

Mar. 4, 2015 — A new study finds that climate change and past hunting in the remote Tibetan Plateau is forcing female wild yaks onto steeper and steeper ... read more

Mar. 2, 2015 — Norwegian mammals and birds have many different methods of surviving long, intense winter nights. A biologist reveals their secrets for ... read more

Mar. 1, 2015 — A study of how climate change has affected emperor penguins over the last 30,000 years found that only three populations may have survived during the last ice age, and that the Ross Sea in Antarctica ... read more

Feb. 27, 2015 — Using recently released Royal Navy submarine data, researchers have investigated the nature of turbulence in the ocean beneath the Arctic sea-ice. Recent decreases in Arctic sea ice may have a big ... read more

Feb. 23, 2015 — While people in the eastern two-thirds of the U.S have been dealing with Arctic Air, the bulge in the Jet Stream over the eastern Pacific Ocean has been keeping the western third of the U.S. in ... read more

Feb. 20, 2015 — Scientists have managed to quantify how the Greenland Ice Sheet reacted to a warm period 8,000-5,000 years ago. Back then temperatures were 2-4 degrees C warmer than they are in the present. Their ... read more

Feb. 6, 2015 — The entire Iberian Peninsula and the Balearic Islands are in the midst of the first significant cold snap for three winters. However, intense snowfalls, like the one affecting the whole of the north ... read more

Feb. 10, 2015 — Sea ice increases in Antarctica do not make up for the accelerated Arctic sea ice loss of the last decades, a new study finds. As a whole, the planet has been shedding sea ice at an average annual ... read more

Feb. 9, 2015 — Researchers have uncovered the earliest evidence of widespread, human-produced air pollution in South America -- from the Spanish conquest of the ... read more

Feb. 6, 2015 — Norway is dotted with small glaciers and permanent snow patches that contain all sorts of archaeological treasures, from ancient shoes to 5000-year-old arrowheads. But climate change has turned up ... read more

Feb. 5, 2015 — Geologists once thought that, until about 18,000 years ago, a mammoth glacier covered the top two-thirds of Ireland. Recently, however, they found evidence that it wasn't just the top ... read more
