Strong El Niño events cause large changes in Antarctic ice shelves

Mon, 01/08/2018 - 11:16
A new study reveals that strong El Nino events can cause significant ice loss in some Antarctic ice shelves while the opposite may occur during strong La Nina events.

Methane hydrate dissociation off Spitsbergen not caused by climate change

Mon, 01/08/2018 - 11:15
For years, methane emissions from the seabed have been observed in the Arctic Ocean off Spitsbergen. The assumption that the warming of seawater by climate change is responsible for the release of methane, has not been confirmed. Research shows that post-glacial uplift is the most likely cause of methane hydrate break-down.

In Antarctic dry valleys, early signs of climate change-induced shifts in soil

Sat, 01/06/2018 - 09:34
In a study spanning two decades, a team of researchers found declining numbers of soil fauna, nematodes and other animal species in the McMurdo Dry Valleys, one of the world's driest and coldest deserts.

Did ancient irrigation technology travel Silk Road?

Thu, 01/04/2018 - 11:01
Using satellite imaging and drone reconnaissance, archaeologists have discovered an ancient irrigation system that allowed a farming community in northwestern China to raise livestock and cultivate crops in one of the world's driest desert climates.

Scientists find surprising evidence of rapid changes in the Arctic

Wed, 01/03/2018 - 15:02
Scientists have found surprising evidence of rapid climate change in the Arctic: In the middle of the Arctic Ocean near the North Pole, they discovered that the levels of radium-228 have almost doubled over the last decade.

Thermometer for global ocean

Wed, 01/03/2018 - 15:01
There's a new way to measure the average temperature of the ocean.

Researchers use 'global thermometer' to track temperature extremes, droughts

Wed, 01/03/2018 - 11:30
Large areas of Earth's surface are experiencing rising maximum temperatures, which affect virtually every ecosystem on the planet, including ice sheets and tropical forests that play major roles in regulating the biosphere, scientists have reported.

Arctic clouds highly sensitive to air pollution

Wed, 01/03/2018 - 09:11
A study by atmospheric scientists has found that the air in the Arctic is extraordinarily sensitive to air pollution, and that particulate matter may spur Arctic cloud formation. These clouds can act as a blanket, further warming an already-changing Arctic.

Cutting-edge statistics yield new insight into attributing, projecting climate change

Thu, 12/21/2017 - 11:25
Projecting the future of extreme weather events across the globe remains a complex task in climate research -- and one in which statisticians are increasingly playing key roles.

Algae growth reduces reflectivity, enhances Greenland ice sheet melting

Wed, 12/20/2017 - 11:20
New research shows algae growing on the Greenland ice sheet, the Earth's second-largest ice sheet, significantly reduce the surface reflectivity of the ice sheet's bare ice area and contribute more to its melting than dust or black carbon. The new findings could influence scientists' understanding of ice sheet melting and projections of future sea level rise, according to the study's authors.

Life on the ice: For the first time scientists have directly observed living bacteria in polar ice and snow

Wed, 12/20/2017 - 11:20
For the first time scientists have directly observed living bacteria in polar ice and snow -- an environment once considered sterile. The new evidence has the potential to alter perceptions about which planets in the universe could sustain life and may mean that humans are having an even greater impact on levels of CO2 in Earth's atmosphere than accepted evidence from climate history studies of ice cores suggests.

Scientists simulate the climate of Game of Thrones

Tue, 12/19/2017 - 20:54
Winter is coming ... as anyone who watches the hit TV series, Game of Thrones, knows. Some even have their own theories for what causes the strange extended seasons in that world of dragons, kings, queens, and magic. But scientists have gone one stage further, by using a Climate Model to simulate and explore the climate of the world of Game of Thrones.

Tiny red animals dart in the dark under the ice of a frozen Quebec lake

Tue, 12/19/2017 - 13:44
In a frozen lake in Quebec, tiny red creatures zip about under the ice. Biologists report the discovery of active, unusually red, life in a winter lake. Bright pigment may preserve zooplankton's fatty acids from oxidative damage.

The missing link between exploding stars, clouds, and climate on Earth

Tue, 12/19/2017 - 08:13
The study reveals how atmospheric ions, produced by the energetic cosmic rays raining down through the atmosphere, helps the growth and formation of cloud condensation nuclei -- the seeds necessary for forming clouds in the atmosphere.

Warming seas double snowfall around North America's tallest peaks

Tue, 12/19/2017 - 08:10
Research finds dramatic increases in snowfall since the beginning of the Industrial Age and explains global climate connections linking northern mountains with tropical oceans.

Mapping the global impact of shrinking glaciers on river invertebrates

Mon, 12/18/2017 - 11:03
River invertebrates react the same way to decreasing glacier cover wherever in the world they are, say scientists who have evaluated more than one million of them in diverse regions with shrinking glaciers, to determine the impact of global environmental change.

In the footsteps of Jacques Cousteau: Researchers unveil the secret of the Blue Hole stalactite

Mon, 12/18/2017 - 11:02
In 1970, Jacques Cousteau and his team recovered an unusual stalactite from the depths of the Caribbean Sea. Now a geoscientist explains what it reveals about our climate since the last ice age.

Statistical modeling helps fisheries managers remove invasive species

Sat, 12/16/2017 - 14:43
Statisticians and natural resource management researchers worked together to determine the best time and location to capture and remove carps from lake systems.

East Antarctic Ice Sheet has history of instability

Wed, 12/13/2017 - 13:36
The East Antarctic Ice Sheet locks away enough water to raise sea level an estimated 53 meters (174 feet). It's also thought to be among the most stable, not gaining or losing mass even as ice sheets in West Antarctica and Greenland shrink. New research has found that the East Antarctic Ice Sheet may not be as stable as it seems.

Oldest ice core ever drilled outside the polar regions

Wed, 12/13/2017 - 09:46
The oldest ice core ever drilled outside the polar regions may contain ice that formed during the Stone Age -- more than 600,000 years ago, long before modern humans appeared.
