Antarctic study shows central ice sheet is stable since milder times

Fri, 05/05/2017 - 09:36
Central parts of Antarctica's ice sheet have been stable for millions of years, from a time when conditions were considerably warmer than now, research suggests.

Policies to curb short-lived climate pollutants could yield major health benefits

Thu, 05/04/2017 - 15:14
A commitment to reducing global emissions of short-lived climate pollutants (SLCPs) such as methane and black carbon could slow global warming while boosting public health and agricultural yields, aligning the Paris Climate Agreement with global sustainable development goals, a new analysis by an international panel of scientists shows.

Decades of data on world's oceans reveal a troubling oxygen decline

Thu, 05/04/2017 - 09:43
The amount of dissolved oxygen contained in the water -- an important measure of ocean health -- has been declining for more than 20 years, reveals a new analysis of decades of data on oceans across the globe.

Earth sank twice, flooding the Eastern Amazon

Wed, 05/03/2017 - 14:20
A tiny shark tooth, part of a mantis shrimp and other microscopic marine organisms reveal that as the Andes mountains rose, the Eastern Amazon sank twice, each time for less than a million years.

Spotted skunk evolution driven by climate change, suggest researchers

Wed, 05/03/2017 - 12:19
Climate plays a key role in determining what animals can live where. And while human-induced climate change has been causing major problems for wildlife as of late, changes in the Earth's climate have impacted evolution for millions of years -- offering tantalizing clues into how to protect animals facing climate change today. In a new paper, scientists have delved into the effects of Ice Age climate change upon the evolution of tiny, hand-standing skunks.

Climate instability over the past 720,000 years

Tue, 05/02/2017 - 08:51
A new analysis of an ice core from Dome Fuji in Antarctica, along with climate simulation results, shows a high degree of climate instability (that is, rapid climate fluctuations) within glacial periods with intermediate temperatures. This instability was attributed primarily to global cooling caused by a reduced greenhouse effect.

Antarctic ice rift spreads

Tue, 05/02/2017 - 08:51
The rift in the Larsen C ice shelf in Antarctica now has a second branch, which is moving in the direction of the ice front, researchers revealed after studying the latest satellite data. The main rift in Larsen C, which is likely to lead to one of the largest icebergs ever recorded, is currently 180 km long. The new branch of the rift is 15 km long.

Antarctic Peninsula ice more stable than thought

Tue, 05/02/2017 - 07:40
Glacier flow at the southern Antarctic Peninsula has increased since the 1990s, but a new study has found the change to be only a third of what was recently reported.

Norway's oldest ice found in central Norway

Mon, 05/01/2017 - 08:47
Parts of the ice of the Juvfonne snow patch in Jotunheimen are 7600 years old, which makes it the oldest dated ice on mainland Norway.

Ice cave in Transylvania yields window into region's past

Thu, 04/27/2017 - 12:08
Ice cores drilled from a glacier in a cave in Transylvania offer new evidence of how Europe's winter weather and climate patterns fluctuated during the last 10,000 years, known as the Holocene period.

Is climate change responsible for record-setting extreme weather events?

Tue, 04/25/2017 - 17:21
After an unusually intense heat wave, downpour or drought, climate scientists inevitably receive phone calls and emails asking whether human-caused climate change played a role.

Century-old mystery of Blood Falls solved

Tue, 04/25/2017 - 08:23
A century-old mystery involving a famous red waterfall in Antarctica has now been solved by researchers. New evidence links Blood Falls to a large source of salty water that may have been trapped under Taylor Glacier for more than 1 million years.

New atlas provides highest-resolution imagery of the Polar Regions seafloor

Tue, 04/25/2017 - 08:23
Scientists have created the most comprehensive and high-resolution atlas of the seafloor of both Polar Regions.

Warm winds: New insight into what weakens Antarctic ice shelves

Tue, 04/25/2017 - 08:23
New research describes for the first time the role that warm, dry winds play in influencing the behavior of Antarctic ice shelves.

Predicting the movement, impacts of microplastic pollution

Tue, 04/25/2017 - 08:22
Microplastics, which are particles measuring less than 5 mm, are of increasing concern. They not only become more relevant as other plastic marine litter breaks down into tiny particles, they also interact with species in a range of marine habitats. A new study takes a look at how global climate change and the impact of changing ocean circulation affects the distribution of marine microplastic litter.

Climate change clues revealed by ice sheet collapse

Mon, 04/24/2017 - 08:39
The rapid decline of ancient ice sheets could help scientists predict the impact of modern-day climate and sea-level change, according to new research.

Towards a liveable future

Fri, 04/21/2017 - 08:16
Humans have influenced nature since as early as the Ice Age, and over the past century our impact has become even greater with our many new technologies and a growing world population. Researchers have studied this impact and how we can keep it within reasonable limits so that nature can be preserved. We cannot do without nature: we need it for our food and for raw materials, as well as for relaxation.

Water is streaming across Antarctica

Wed, 04/19/2017 - 12:17
In the first such continent-wide survey, scientists have found extensive drainages of meltwater flowing over parts of Antarctica's ice during the brief summer.

In new paper, scientists explain climate change using before/after photographic evidence

Wed, 04/19/2017 - 11:20
A group of scientists offers photographic proof of climate change using images of retreating glaciers.

Arctic river ice deposits rapidly disappearing

Tue, 04/18/2017 - 10:14
Climate change is causing thick ice deposits that form along Arctic rivers to melt nearly a month earlier than they did 15 years ago, a new study finds.
