Greenland ice flow likely to speed up

Wed, 08/16/2017 - 13:18
Flow of the Greenland Ice Sheet is likely to speed up in the future, despite a recent slowdown, because its outlet glaciers slide over wet sediment, not hard rock, new research based on seismic surveys has confirmed. This sediment will become weaker and more slippery as global temperatures rise and meltwater supply becomes more variable. The findings challenge the view that the recent slowdowns in ice flow would continue in the long term.

Mystery of how first animals appeared on Earth solved

Wed, 08/16/2017 - 12:47
Research has solved the mystery of how the first animals appeared on Earth, a pivotal moment for the planet without which humans would not exist.

Lake trout adjust their behavior in the face of a changing climate, new study

Wed, 08/16/2017 - 08:04
Certain lake predators are altering their behavior due to climate change, revealing what the future may hold for these fish and their food, scientists have discovered.

World's largest volcanic range may lurk beneath Antarctic ice

Mon, 08/14/2017 - 08:27
West Antarctica's vast ice sheet conceals what may be the largest volcanic region on Earth, new research has revealed.

Lunar dynamo's lifetime extended by at least 1 billion years

Wed, 08/09/2017 - 13:20
Astronomers report that a lunar rock collected by NASA's Apollo 15 mission exhibits signs that it formed 1 to 2.5 billion years ago in the presence of a relatively weak magnetic field of about 5 microtesla. That's around 10 times weaker than Earth's current magnetic field but still 1,000 times larger than fields in interplanetary space today.

Antarctic bacterium has one of the biggest proteins ever found

Wed, 08/09/2017 - 13:20
A bacterium living in the icy-cold waters of Antarctica manages to survive by gripping on to the ice surface. The protein used by the bacterium to do this -- a kind of extendable anchor -- has been detailed by a group of researchers. Quite special, because at 600 nanometers, it is one of the biggest proteins for which the structure has ever been identified.

Post-glacial history of Lake of the Woods

Wed, 08/09/2017 - 06:36
The extent and depth of lakes in glaciated regions of North America are controlled by climate and the influence of differential isostatic rebound of the land's surface that began when Pleistocene ice melted from the continent. This relationship and the post-glacial history of Lake of the Woods -- one of the largest lake complexes in North America and the source of water for the city of Winnipeg -- is presented for the first time in a new study by five Canadian researchers.

2016 was another warm year, report confirms

Wed, 08/09/2017 - 06:33
A new report confirms that 2016 was another exceptionally warm year, with global temperature having reached 0.77± 0.09 degrees C above its level between 1961 and 1990.

Not all glaciers in Antarctica have been affected by climate change

Tue, 08/08/2017 - 17:23
The effects of climate change, which are apparent in other parts of the Antarctic continent, are not yet observed for glaciers in the western Ross Sea coast, new research indicates.

No longer water under the bridge, statistics yields new data on sea levels

Tue, 08/08/2017 - 13:59
While the scientific community has long warned about rising sea levels and their destructive impact on some of the United States' most populous cities, researchers have developed a new, statistical method that more precisely calculates the rate of sea level rise, showing it's not only increasing, but accelerating.

Laser mapping project shows effects of physical changes in Antarctica's Dry Valleys

Tue, 08/08/2017 - 13:53
Researchers have publicly released high-resolution maps of Antarctica's McMurdo Dry Valleys, a globally unique polar desert.

Researchers crack the 'Karakoram anomaly': Why glaciers near K2 are growing in size

Mon, 08/07/2017 - 10:28
Researchers identify 'Karakoram vortex' and explain why glaciers near K2 are growing in size.

Extreme melt season leads to decade-long ecosystem changes in Antarctic polar desert

Mon, 08/07/2017 - 10:15
An abnormal season of intense glacial melt in 2002 triggered multiple distinct changes in the physical and biological characteristics of Antarctica's McMurdo Dry Valleys over the ensuing decade, report investigators.

Alaska's North Slope snow-free season is lengthening

Thu, 08/03/2017 - 13:10
On the North Slope of Alaska, snow is melting earlier in the spring and the snow-in date is happening later in the fall, according to a new study.

Climate change could put rare bat species at greater risk

Wed, 08/02/2017 - 08:27
An endangered bat species with a UK population of less than 1,000 could be further threatened by the effects of global warming, according to a new study.

Update on the Larsen-C iceberg breakaway

Wed, 08/02/2017 - 07:29
Since an iceberg four times the size of London broke free earlier this month, scientists have continued to track its progress using satellites. Their observations show the Larsen-C story might not be over yet.

Glaciers may have helped warm Earth

Mon, 07/31/2017 - 15:44
Weathering of Earth by glaciers may have warmed the planet over eons by aiding the release of carbon dioxide into the atmosphere. A new study shows the cumulative effect may have created negative feedback that prevented runaway glaciation.

Methane-eating microbes may reduce release of gases as Antarctic ice sheets melt

Mon, 07/31/2017 - 12:41
A lake beneath the West Antarctic ice sheet contains large amounts of methane and describes how methane-eating microbes may keep the climate-warming gas from entering the atmosphere.

Loss of Arctic sea ice impacting Atlantic Ocean water circulation system

Mon, 07/31/2017 - 10:46
Arctic sea ice is not merely a passive responder to the climate changes occurring around the world, according to new research. Scientists say the ongoing Arctic ice loss can play an active role in altering one of the planet's largest water circulation systems: the Atlantic Meridional Overturning Circulation (AMOC).

Summer sea ice melt in the Arctic

Mon, 07/24/2017 - 12:31
Earlier this year Arctic sea ice sank to a record low wintertime extent for the third straight year. Now NASA is flying a set of instruments north of Greenland to observe the impact of the melt season on the Arctic's oldest and thickest sea ice.
