Tracking glaciers with accelerators

Thu, 02/05/2015 - 11:27
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 two-thirds: The Irish glacier was much larger, completely engulfing the country and extending far offshore.

Methane seepage from Arctic seabed occurring for millions of years

Thu, 02/05/2015 - 09:19
Natural seepage of methane offshore the Arctic archipelago Svalbard has been occurring periodically for at least 2.7 million years. Major events of methane emissions happened at least twice during this period, according to a new study.

Heavy rainfall events becoming more frequent on Big Island, Hawaii

Thu, 02/05/2015 - 08:52
A recent study determined that heavy rainfall events have become more frequent over the last 50 years on Hawai'i Island. For instance, a rare storm with daily precipitation of nearly 12 inches, occurring once every 20 years by 1960, has become a rather common storm event on the Big Island of Hawai'i -- returning every 3-5 years by 2009.

Evidence from warm past confirms recent IPCC estimates of climate sensitivity

Wed, 02/04/2015 - 12:41
New evidence showing the level of atmospheric carbon dioxide millions of years ago supports recent climate change predictions from the Intergovernmental Panel on Climate Change.

Earth's orbit affects the stability of Antarctica's Eastern ice cap

Tue, 02/03/2015 - 08:43
Scientists have found that there is a direct relation between the changes in the earth's orbit and the stability of the Eastern ice cap of Antarctica, more specifically, on the continental fringe of Wilkes Land (East Antarctica).

Iceland rises as its glaciers melt from climate change

Thu, 01/29/2015 - 10:37
Earth's crust under Iceland is rebounding as global warming melts the island's great ice caps. In south-central Iceland some sites are moving upward as much as 1.4 inches (35 mm) per year. A new paper is the first to show the current fast uplift of the Icelandic crust is a result of accelerated melting of the island's glaciers and coincides with the onset of warming that began about 30 years ago, the researchers said.

Erratic as normal: Arctic sea ice loss expected to be bumpy in the short term

Wed, 01/28/2015 - 15:05
Arctic sea ice extent plunged precipitously from 2001 to 2007, then barely budged between 2007 and 2013. Even in a warming world, researchers should expect such unusual periods of no change -- and rapid change -- at the world's northern reaches, according to a new paper.

Smothered oceans: Extreme oxygen loss in oceans accompanied past global climate change

Wed, 01/28/2015 - 14:21
From the subarctic Pacific to the Chilean margins, extreme oxygen loss is stretching from the upper ocean to about 3,000 meters deep. In some oceanic regions, such loss occurred within 100 years or less, according to a new study.

Nordic marine scientists: Showcasing growing pressure on oceans?

Wed, 01/28/2015 - 10:38
A group of 13 scientists argue that the Nordic countries are in a unique position to showcase how to handle the growing pressure on the oceans. However, this relies on a collective ability to regard change as connected.

Early Mesoamericans affected by climate change

Tue, 01/27/2015 - 13:08
Scientists have reconstructed the past climate for the region around Cantona, a large fortified city in highland Mexico, and found the population drastically declined in the past, at least in part because of climate change.

Winters in Siberian permafrost regions have warmed since millenia

Mon, 01/26/2015 - 11:47
For the first time, researchers have successfully decoded climate data from old permafrost ground ice and reconstructed the development of winter temperatures in Russia's Lena River Delta. Their conclusions: over the past 7,000 years, winter temperatures in the Siberian permafrost regions have gradually risen.

3-D view of Greenland Ice Sheet opens window on ice history

Fri, 01/23/2015 - 13:09
Scientists using ice-penetrating radar have created 3-D maps of the age of the ice within the Greenland Ice Sheet. The new maps will aid future research to understand the impact of climate change on the ice sheet. The Greenland Ice Sheet is the second largest mass of ice on Earth, containing enough water to raise ocean levels by about 20 feet.

Climate affects development of human speech

Fri, 01/23/2015 - 09:25
A correlation between climate and the evolution of language has been uncovered by researchers. To find a relationship between the climate and the evolution of language, one needs to discover an association between the environment and vocal sounds that is consistent throughout the world and present in different languages. And that is precisely what a group of researchers has done.

Arctic ice cap slides into the ocean

Fri, 01/23/2015 - 07:17
Satellite images have revealed that a remote Arctic ice cap has thinned by more than 50 metres since 2012 -- about one sixth of its original thickness -- and that it is now flowing 25 times faster. The findings show that over the last two decades, ice loss from the south-east region of Austfonna, located in the Svalbard archipelago, has increased significantly. In this time, ice flow has accelerated to speeds of several kilometres per year, and ice thinning has spread more than 50km inland -- to within 10km of the summit.

Drillers help make new Antarctic discoveries

Wed, 01/21/2015 - 13:48
An expedition to Antarctica yields new information about how climate change affects Antarctic glaciers. The study has discovered a new ecosystem, researchers report, including a unique ecosystem of fish and invertebrates living in an estuary deep beneath the Antarctic ice.

Two lakes beneath the ice in Greenland, gone within weeks

Wed, 01/21/2015 - 12:51
Researchers discovered craters left behind when two sub-glacial lakes in Greenland drained away -- an indication that the natural plumbing system beneath the ice sheet is overflowing with meltwater. One lake once held billions of gallons of water and emptied to form a mile-wide crater in just a few weeks. The other lake has filled and emptied twice in the last two years.

Death of a dynamo: A hard drive from space

Hidden magnetic messages contained within ancient meteorites are providing a unique window into the processes that shaped our solar system, and may give a sneak preview of the fate of the Earth's core as it continues to freeze.

Greenland Ice: The warmer it gets the faster it melts

Tue, 01/20/2015 - 14:12
Melting of glacial ice will probably raise sea level around the globe, but how fast this melting will happen is uncertain. In the case of the Greenland Ice Sheet, the more temperatures increase, the faster the ice will melt, according to computer model experiments by geoscientists.

Climate change does not bode well for picky eaters

Tue, 01/20/2015 - 11:13
In a part of the world that is experiencing the most dramatic increase in temperature and climate change, two very similar species of animals are responding very differently. New research suggests that how these species have adapted to co-exist with one another might be to blame.

Giant atmospheric rivers add mass to Antarctica's ice sheet

Tue, 01/20/2015 - 10:22
Extreme weather phenomena called atmospheric rivers were behind intense snowstorms recorded in 2009 and 2011 in East Antarctica. The resulting snow accumulation partly offset recent ice loss from the Antarctic ice sheet, report researchers.
