Underwater robot sheds new light on thick, deformed, Antarctic sea ice

Mon, 11/24/2014 - 11:53
The first detailed, high-resolution 3-D maps of Antarctic sea ice have been developed using an underwater robot. Scientists say the new technology provides accurate ice thickness measurements from areas that were previously too difficult to access.

Time-lapse photos and synched weather data unlock Antarctic secrets

Thu, 11/20/2014 - 17:36
Researchers are using time-lapse photography, linked to weather data, to study climate and geological change in the Antarctic Dry Valleys.

Salinity counts when it comes to sea level

Thu, 11/20/2014 - 12:34
Using ocean observations and a large suite of climate models, scientists have found that long-term salinity changes have a stronger influence on regional sea level changes than previously thought.

Cut the salt: Green solutions for highway snow, ice control

Thu, 11/20/2014 - 08:17
Ice-free pavement. 'Smart snowplows.' Vegetable juice ice-melt. Cold-climate researchers are clearing the road with green alternatives to the salt, sand and chemicals typically used for highway snow and ice control.

Permafrost soil: Possible source of abrupt rise in greenhouse gases at end of last ice age

Thu, 11/20/2014 - 07:23
Scientists have identified a possible source of carbon dioxide and other greenhouse gases that were abruptly released to the atmosphere in large quantities around 14,600 years ago.

Laser from a plane discovers Roman goldmines in Spain

Thu, 11/20/2014 - 07:21
Hidden under the vegetation and crops of the Eria Valley, in León (Spain), there is a gold mining network created by the Romans two thousand years ago, as well as complex hydraulic works, such as river diversions, to divert water to the mines of the precious metal. Researchers made the discovery from the air with an airborne laser teledetection system.

Wild weather in the Arctic causes problems for people and wildlife

Wed, 11/19/2014 - 19:45
The residents of Longyearbyen, the largest town on the Norwegian arctic island archipelago of Svalbard, remember it as the week that the weather gods caused trouble.  Temperatures were ridiculously warm – and reached a maximum of nearly +8 degrees C in one location at a time when mean temperatures are normally -15 degrees C. It rained in record amounts.

Little Ice Age was global: Implications for current global warming

Wed, 11/19/2014 - 19:45
Researchers have shed new light on the climate of the Little Ice Age, and rekindled debate over the role of the sun in climate change. The new study, which involved detailed scientific examination of a peat bog in southern South America, indicates that the most extreme climate episodes of the Little Ice Age were felt not just in Europe and North America, which is well known, but apparently globally. The research has implications for current concerns over ‘Global Warming’.

'Fountain of youth' underlies Antarctic mountains: Why peaks buried in ice look so young

Wed, 11/19/2014 - 09:20
Scientists have now explained why the ice-covered Gamburtsev Mountains in the middle of Antarctica looks as young as they do.

Surviving an ice age: Mammals didn't play by the rules of modeling on where they migrated to survive last ice age

Tue, 11/18/2014 - 14:32
Leave it to long-dead short-tailed shrew and flying squirrels to outfox climate-modelers trying to predict future habitats. Evidence from the fossil record shows that gluttonous insect-eating shrew didn't live where a species distribution technique drawn by biologists put it 20,000 years ago to survive the reach of glaciers. The shrew is not alone.

Jurassic climate of large swath of western U.S. was more complex than previously known: Unexpected abrupt change from arid to wet

Tue, 11/18/2014 - 11:54
Climate over a large swath of the western US was more complex during the Jurassic than previously known, according to new research. Instead of a gradual transition from dry to wetter, chemical analysis of ancient soils reveals an unexpected abrupt change, say paleontologists. Samples were from the Morrison Formation, a massive rock unit sprawling across 13 states and Canada that's produced significant dinosaur discoveries for over 100 years.

Climate change was not to blame for the collapse of the Bronze Age

Mon, 11/17/2014 - 15:41
Scientists will have to find alternative explanations for a huge population collapse in Europe at the end of the Bronze Age as researchers prove definitively that climate change -- commonly assumed to be responsible -- could not have been the culprit.

Tillage shows very little impact on carbon sequestration

Mon, 11/17/2014 - 08:31
Reducing or eliminating tillage is one of the farming practices most frequently touted to improve carbon sequestration in soil. A new study turns this paradigm on its head. This study, the result of a rigorous experiment conducted in the Ile-de-France region, shows that after a period of 41 years, three tillage methods led to similar carbon sequestration outcomes. However, variations were apparent over time based on climate conditions.

Climate capers of the past 600,000 years

Mon, 11/17/2014 - 07:46
If you want to see into the future, you have to understand the past. Researchers have drilled deposits on the bed of Lake Van (Eastern Turkey) which provide unique insights into the last 600,000 years. The samples reveal that the climate has done its fair share of mischief-making in the past. Furthermore, there have been numerous earthquakes and volcanic eruptions. The results of the drilling project also provide a basis for assessing the risk of how dangerous natural hazards are for today's population.

Rocky Mountain storms lead to new findings about hailstones

Fri, 11/14/2014 - 11:49
New research shows that hailstones form around biological materials, extending previous findings about the formation of snow and rain.

More reliable thermal readings of Arctic sea ice

Thu, 11/13/2014 - 07:51
Arctic sea ice has diminished significantly in recent decades, particularly in summer. Researchers from Norway and China have collaborated on developing an autonomous buoy with instruments that can more precisely measure the optical properties of Arctic sea ice while also taking measurements of ice thickness and temperature.

A tale of two seas: Last Ice Age has shaped sharks across Europe

Wed, 11/12/2014 - 11:02
Shark populations in the Mediterranean are highly divided, an international team of scientists has shown. The study used genetic techniques to investigate the population structure of the small-spotted shark, Scyliorhinus canicula. The species is common throughout Europe and has been eaten since ancient times, as documented in Roman mosaics.

Global warming not just a blanket: In the long run, it's more like tanning oil

Mon, 11/10/2014 - 15:11
Instead of carbon dioxide being like a blanket that slowly warms the planet, after about a decade most warming comes from melting ice and snow and a more moist atmosphere, which both cause Earth to absorb more shortwave radiation from the sun.

Robotic ocean gliders aid study of melting polar ice

Mon, 11/10/2014 - 14:09
Researchers use robotic ocean gliders to study how warm water is making its way to Antarctic ice sheets -- and how this warming ultimately leads to rising ocean levels.

Rare 2.5-billion-year-old rocks reveal hot spot of sulfur-breathing bacteria: Sulfur-dependent life forms thrived in oceans

Thu, 11/06/2014 - 13:37
Biogeochemical signals in 2.5-billion-year-old carbonate rocks from Brazil reveal that sulfur-consuming bacteria were active at a time when ocean sulfur levels were low. Geologists focused on sulfur isotopes in ancient carbonate rocks. The study sheds light on Earth's early atmospheric chemistry.
