Climate change could trigger strong sea level rise

Thu, 01/05/2017 - 11:31
About 15,000 years ago, the ocean around Antarctica has seen an abrupt sea level rise of several meters. It could happen again.

Potential instability in Atlantic Ocean water circulation system

Wed, 01/04/2017 - 14:43
One of the world's largest ocean circulation systems may not be as stable as today's weather models predict, according to a new study. In fact, changes in the Atlantic Meridional Overturning Circulation -- the same deep-water ocean current featured in the movie 'The Day After Tomorrow' -- could occur quite abruptly, in geologic terms, the study says.

The fire through the smoke: Working for transparency in climate projections

Wed, 01/04/2017 - 10:43
To help policymakers more confidently prepare for the effects of climate change, a group of preeminent climate scientists evaluated the scientific work and expert judgments behind the most recent projections from the Intergovernmental Panel on Climate Change regarding the potential ecological, social, economic and meteorological repercussions of climate change.

Researchers explore link between tropical glaciers, water supply

Wed, 01/04/2017 - 09:36
Researchers are closer to understanding how the loss of glaciers in the Cordillera Blanca of Peru is affecting water resources in a region responding to global climate change.

When the Arctic coast retreats, life in the shallow water areas drastically changes

Wed, 01/04/2017 - 09:35
The thawing and erosion of Arctic permafrost coasts has dramatically increased in the past years and the sea is now consuming more than 20 meters of land per year at some locations.

Closely related yet so different

Thu, 12/22/2016 - 08:48
Southeast Asia is home to numerous felids, including the Asian golden cat and the bay cat. The two cat species are closely related sister species which split from each other 3.16 million years ago. Yet, their more recent history was quite different. Scientists could now show that, after a massive volcanic eruption about 73,000 years ago, the Asian golden cat survived only in Indochina, from where it expanded its range in dramatic fashion during the peak of the last Ice Age. The cooler and drier climates at the time pushed its sister species, the bay cat, however, into rainforest refuges on Borneo.

Leaky plumbing impedes greenland ice sheet flow

Tue, 12/20/2016 - 16:51
Surface meltwater that drains to the bed of the Greenland Ice Sheet each summer causes changes in ice flow that cannot be fully explained by prevailing theories.

Scientists bear witness to birth of an ice cloud

Tue, 12/20/2016 - 08:46
Scientists have witnessed the birth of atmospheric ice clouds, creating ice cloud crystals in the laboratory and then taking images of the process through a microscope, essentially documenting the very first steps of cloud formation.

Warmer climate threatening to northern birds

Tue, 12/20/2016 - 08:39
Will northern birds such as the Siberian jay and the red-flanked bluetail be gone in 50 years? There is a huge risk since a deteriorating climate for breeding is imminent. Another six species are also under threat and will require particular conservation actions in order to survive, according to a researcher who has developed a species analysis method.

Satellites observe 'traffic jams' in Antarctic Ice Stream caused by tides

Mon, 12/19/2016 - 12:44
Nine months of continual radar observation reveals the complex changing patterns of ice stream movement in three dimensions that can inform predictions for the speed at which the ice caps will respond to a warming climate.

Studies refute hypothesis on what caused abrupt climate change thousands of years ago

Mon, 12/19/2016 - 10:53
Two new studies refute the hypothesis that one or more comets/bolides struck North America approximately 12,900 years ago triggering rapid climate change and the start of the Younger Dryas period.

Arctic lakes thawing earlier each year

Mon, 12/19/2016 - 07:50
Arctic lakes, covered with ice during the winter months, are melting earlier each spring, research has found. The team, who monitored 13,300 lakes using satellite imagery, have shown that on average ice is breaking up one day earlier per year, based on a 14-year period between 2000 and 2013.

Rising sea level estimates require collaborative response, experts say

Thu, 12/15/2016 - 13:33
Policymakers and scientists must act quickly and collaboratively to help coastal areas better prepare for rising sea levels globally, say climate change experts.

Scientists measure pulse of CO<sub>2</sub> emissions during spring thaw in the Arctic

Wed, 12/14/2016 - 14:16
Scientists documented a spring pulse in northern Alaska in 2014 that included carbon dioxide emissions equivalent to 46 percent of the net carbon dioxide that is absorbed in the summer months and methane emissions that added 6 percent to summer fluxes. What's more, recent climate trends may make such emissions more frequent, the scientists conclude.

Earth's magnetic fields could track ocean heat, study proposes

Tue, 12/13/2016 - 08:31
As Earth warms, much of the extra heat is stored in the planet's ocean. Monitoring the magnitude of that heat content is difficult, but a surprising feature of the tides could help. Scientists are developing a new way to use satellite observations of magnetic fields to measure heat stored in the ocean.

What satellites can tell us about how animals will fare in a changing climate

Mon, 12/12/2016 - 14:59
From the Arctic to the Mojave Desert, terrestrial and marine habitats are quickly changing. Satellites are particularly well-suited to observe habitat transformation and help scientists forecast what animals might do next, suggest experts.

Sawdust reinvented into super sponge for oil spills

Mon, 12/12/2016 - 14:26
Oil spills could be cleaned up in the icy, rough waters of the Arctic with a chemically modified sawdust material that absorbs up to five times its weight in oil and stays afloat for at least four months.

Jersey was a must-see tourist destination for Neanderthals for over 100,000 years

Mon, 12/12/2016 - 12:34
Neanderthals kept coming back to a coastal cave site in Jersey from at least 180,000 years ago until around 40,000 years ago. researchers report. As part of a re-examination of La Cotte de St Brelade and its surrounding landscape, archaeologists have taken a fresh look at artefacts and mammoth bones originally excavated from within the site's granite cliffs in the 1970s.

How the Antarctic Ice Sheet is affecting climate change

Mon, 12/12/2016 - 10:58
An international team of researchers has concluded that the Antarctic Ice Sheet actually plays a major role in regional and global climate variability -- a discovery that may also help explain why sea ice in the Southern Hemisphere has been increasing despite the warming of the rest of the Earth.

Mysterious 'crater' on Antarctica indication of vulnerable ice sheet

Mon, 12/12/2016 - 10:58
The East Antarctic ice sheet is more vulnerable than expected, due to a strong wind that brings warm air and blows away the snow. Scientists combined climate models, satellite observations and on-site measurements.
