What did Earth's ancient magnetic field look like?

Fri, 06/24/2016 - 12:58
Earth's ancient magnetic field was significantly different than the present day field, originating from several poles rather than the familiar two, new research suggests. Then, shortly after our planet's core solidified, this work predicts that Earth's magnetic field transitioned to a 'strong,' two-pole one.

Researchers offer new theory on how climate affects violence

Fri, 06/24/2016 - 10:00
Researchers have long struggled to explain why some violent crime rates are higher near the equator than other parts of the world. Now, a team of researchers has developed a model that could help explain why.

Siberian larch forests are still linked to the ice age

Fri, 06/24/2016 - 09:02
The Siberian permafrost regions include those areas of the Earth, which heat up very quickly in the course of climate change. Nevertheless, biologists are currently observing only a minimal response in forest composition.

New technique settles old debate on highest peaks in US Arctic

Thu, 06/23/2016 - 10:21
Finding out which is the highest mountain in the US Arctic may be the last thing on your mind, unless you are an explorer who skis from the tallest peaks around the globe. A ski mountaineer and a glaciologist aimed to settle a debate of more than 50 years, while testing a new, affordable mapping technique in a steep mountainous region.

Explosive renewables development can deliver on Paris

Thu, 06/23/2016 - 05:50
While some criticize the Paris climate target as impracticable, a team of scholars argues that it is a triumph of realism. First, keeping global warming well below 2 degrees Celsius is necessary in view of the risks that unchecked climate change would pose. The scientists provide for the first time a diagram summarizing the tipping points/temperature issue. Second, implementing the Paris target is feasible through an explosive development of renewables. Third, the target is simple enough to create worldwide political momentum.

Cosmopolitan snow algae accelerate the melting of Arctic glaciers

Wed, 06/22/2016 - 09:19
The role of red pigmented snow algae in melting Arctic glaciers has been strongly underestimated, suggests a study. The new work shows a 13 percent reduction of the albedo over the course of one melting season caused by red-pigmented snow algal blooms.

Mystery of powerful lightning at sea not solved completely

Mon, 06/20/2016 - 11:04
The mystery of why most of the most powerful lightning on Earth happens over the oceans isn't solved, but a few of the usual suspects are no longer in custody. It's possible the increased presence of salt in the atmosphere plays a role.

Ancient DNA shows perfect storm felled Ice Age giants

Fri, 06/17/2016 - 15:03
Giant Ice Age species including elephant-sized sloths and powerful sabre-toothed cats that once roamed the windswept plains of Patagonia, southern South America, were finally felled by a perfect storm of a rapidly warming climate and humans, a new study has shown.

Permafrost thawing below shallow Arctic lakes

Thu, 06/16/2016 - 13:13
Permafrost below shallow Arctic lakes is thawing as a result of changing winter climate, new research shows. These rates of warming are similar to those observed in terrestrial permafrost, yet those soils are still well below freezing and thaw is not expected for at least another 70 years. However, a regime shift in lake ice is leading to sub-lake permafrost thaw now.

700-year-old West African soil technique could help mitigate climate change

Thu, 06/16/2016 - 09:59
A 700-year-old fertile soil technique could mitigate climate change and revolutionize farming across Africa, say researchers. They discovered that the ancient West African method of adding charcoal and kitchen waste to highly weathered, nutrient poor tropical soils can transform the land into enduringly fertile, carbon-rich black soils which the researchers dub 'African Dark Earths'.

Huge ancient river basin explains location of the world's fastest flowing glacier

Tue, 06/14/2016 - 10:44
An ancient basin hidden beneath the Greenland ice sheet may help explain the location, size and velocity of Greenland's fastest flowing outlet glacier. The research also provides an insight into what past river drainage looked like in Greenland, and what it could look like in the future as the ice sheet retreats.

Drying Arctic soils could accelerate greenhouse gas emissions

Mon, 06/13/2016 - 15:49
Soil moisture levels will determine how much carbon is released to the atmosphere as rising temperatures thaw Arctic lands, suggests new scientific research.

Antarctic lakes are a repository for ancient soot

Mon, 06/13/2016 - 13:46
Remote lakes in a perpetually ice-free area of Antarctica show not only the chemical signature of ancient wildfires, but also some much more recent evidence of fossil-fuel combustion, according to new research.

New research reveals secrets of former subglacial lakes in North America

Mon, 06/13/2016 - 12:07
Researchers have provided a unique glimpse into one of the least understood environments on Earth by revealing for the first time former subglacial lakes and their drainage routes beneath the North American ice sheets.

'Weather@Home' offers precise new insights into climate change in the West

Thu, 06/09/2016 - 13:23
Tens of thousands of 'citizen scientists' have volunteered some use of their personal computer time to help researchers create one of the most detailed, high resolution simulations of weather ever done in the Western United States. This approach will ultimately help improve future predictions of regional climate and answer very specific questions.

Research accelerates next-generation ultra-precise sensing technology

Thu, 06/09/2016 - 10:55
The mining, navigation, minerals exploration and environmental hydrology sectors are set to benefit from new research into quantum technology, say experts.

How El Niño impacts global temperatures

Thu, 06/09/2016 - 10:51
Scientists have found past El Niño oscillations in the Pacific Ocean may have amplified global climate fluctuations for hundreds of years at a time.The team uncovered century-scale patterns in Pacific rainfall and temperature, and linked them with global climate changes in the past 2,000 years, which will influence climate models of current trends.

Greenland's 2015 melt records consistent with 'Arctic amplification'

Thu, 06/09/2016 - 05:45
Following record-high temperatures and melting records that affected northwest Greenland in summer 2015, a new study provides the first evidence linking melting in Greenland to the anticipated effects of a phenomenon known as Artic amplification.

Early farmers from across Europe were direct descendants of Aegeans

Mon, 06/06/2016 - 14:49
Paleogeneticists have shown that early farmers from across Europe have an almost unbroken trail of ancestry leading back to the Aegean.

Ice age bison fossils shed light on early human migrations in North America

Mon, 06/06/2016 - 14:48
Scientists using evidence from bison fossils have determined when an ice-free corridor opened up along the Rocky Mountains during the late Pleistocene. The corridor has been considered a potential route for human and animal migrations between the far north (Alaska and Yukon) and the rest of North America, but when and how it was used has long been uncertain.
