Billions of juvenile fish under the Arctic sea ice

Tue, 10/13/2015 - 10:19
Using a new net, marine biologists have, for the first time, been able to catch polar cod directly beneath the Arctic sea ice with a trawl, allowing them to determine their large-scale distribution and origin. This information is of fundamental importance, as polar cod are a major source of food for seals, whales and seabirds in the Arctic.

Melting of Antarctic ice shelves set to intensify

Mon, 10/12/2015 - 10:57
New research projects a doubling of surface melting of Antarctic ice shelves by 2050 and that by 2100 melting may surpass intensities associated with ice shelf collapse, if greenhouse gas emissions from fossil fuel consumption continue at the present rate.

Paleoclimate researchers find connection between carbon cycles, climate trends

Fri, 10/09/2015 - 14:55
Making predictions about climate variability often means looking to the past to find trends. Now paleoclimate researchers have found clues in exposed bedrock alongside an Alabama highway that could help forecast climate variability. In their study, the researchers verified evidence suggesting carbon dioxide decreased significantly at the end of the Ordovician Period, 450 million years ago, preceding an ice age and eventual mass extinction. These results will help climatologists better predict future environmental changes.

Horn of Africa drying ever faster as climate warms

Fri, 10/09/2015 - 14:52
The Horn of Africa has become increasingly arid in sync with the global and regional warming of the last century and at a rate unprecedented in the last 2,000 years, according to new research. The scientists suggest that as global and regional warming continues, the eastern Horn of Africa -- which includes Somalia, Djibouti and Ethiopia -- will receive progressively less rain during the crucial 'long rains' season of March, April and May.

Unexpected information about Earth's climate history from Yellow River sediment

Fri, 10/09/2015 - 07:30
By meticulously examining sediments in China's Yellow River, a Swedish-Chinese research group are showing that the history of tectonic and climate evolution on Earth may need to be rewritten.

Greenland's ice sheet plumbing system revealed

Fri, 10/09/2015 - 07:30
Pioneering new research sheds light on the impact of climate change on subglacial lakes found under the Greenland ice sheet. A team of experts has studied the water flow paths from one such subglacial lake, which drained beneath the ice sheet in 2011.

Quantifying the impact of climate on ecosystems worldwide

Thu, 10/08/2015 - 13:25
Record-breaking temperatures and droughts are directly affecting ecosystems worldwide, an international research team of life scientists reports.

MacGyver this! New DYI experiment shows students the physics of climate change

Thu, 10/08/2015 - 10:04
Fishing line, paper clips, glass marble, glue -- no, not the makings of a MacGyver episode but a new experiment that lets students precisely measure the effects of global warming on oceans.

Earth's inner core was formed 1-1.5 billion years ago

Wed, 10/07/2015 - 12:56
There have been many estimates for when the earth's inner core was formed, but scientists have used new data which indicates that the Earth's inner core was formed 1-1.5 billion years ago as it 'froze' from the surrounding molten iron outer core.

Tiny ancient fossil from Spain shows birds flew over the heads of dinosaurs

Tue, 10/06/2015 - 13:24
A new discovery documents the intricate arrangement of the muscles and ligaments that controlled the main feathers of the wing of an ancient bird, supporting the notion that at least some of the most ancient birds performed aerodynamic feats in a fashion similar to those of many living birds.

The warmer the higher: Sea-level rise from Filchner-Ronne ice in Antarctica

Mon, 10/05/2015 - 11:10
The more ice is melted of the Antarctic Filchner-Ronne shelf, the more ice flows into the ocean, and the more the region contributes to global sea-level rise. Unlike some some other parts of Antarctica, this region is not characterized by instabilities which, once triggered, can lead to persistent ice discharge into the ocean even without a further increase of warming. So for the Filchner-Ronne ice, this is a tiny bit of good news.

Global warming can alter shape of the planet, as melting glaciers erode the land

Thu, 10/01/2015 - 13:22
Climate change is causing more than just warmer oceans and erratic weather. According to scientists, it also has the capacity to alter the shape of the planet.

Arctic sea ice still too thick for regular shipping route through Northwest Passage

Tue, 09/29/2015 - 11:54
Despite climate change, sea ice in the Northwest Passage (NWP) remains too thick and treacherous for it to be a regular commercial Arctic shipping route for many decades, according to new research. Prior to this research, there was little information about the thickness of sea ice in the NWP. Next to ice coverage and type, sea ice thickness plays the most important role in assessing shipping hazards and predicting ice break-up.

Flood risk on rise for New York City, New Jersey coast, study finds

Mon, 09/28/2015 - 14:58
For the first time, climate researchers compared both sea-level rise rates and storm surge heights in prehistoric and modern eras and found that the combined increases of each have raised the likelihood of a devastating 500-year flood occurring as often as every 25 years.

Antarctic warming stimulates diversity of soil fungi

Mon, 09/28/2015 - 11:34
A landmark study predicts that climate change will have a major impact on life in Antarctica this century. Scientists say that results indicated that by 2100 there would be 25 percent more soil fungal 'species' in the most rapidly warming parts of Antarctica.

How ocean circulation changed atmospheric CO2

Mon, 09/28/2015 - 11:34
Changes to overturning circulation in the Southern Ocean as a result of temperatures over Antarctica play key role in carbon uptake by the oceans.

Ice samples from Greenland, Russia provide clues to past, future climate change

Mon, 09/28/2015 - 07:21
Scientists have discovered evidence of carbonaceous aerosols -- organic dust -- transported from Asia and deposited in the Arctic over the last 450 years, according to a study. They have also found that increased levels of dust were being deposited during warmer periods when the Arctic Oscillation -- changes in the prevailing wind direction centred on the Atlantic -- was at its strongest.

Extreme Pacific sea level events to double in future

Fri, 09/25/2015 - 13:27
Many tropical Pacific island nations are struggling to adapt to gradual sea level rise stemming from warming oceans and melting ice caps. Now they may also see much more frequent extreme sea level swings. The culprit is a projected behavioral change of the El Niño phenomenon and its characteristic Pacific wind response, according to recent computer modeling experiments and tide-gauge analysis.

How fossil corals can shed light on Earth's past climate

Thu, 09/24/2015 - 14:14
Researchers have used radiocarbon measured in deep-sea fossil corals to shed light on carbon dioxide levels during Earth's last deglaciation. Fossil corals have the unique advantage that they can be precisely dated by radiometric uranium-series dating, giving an age scale that can be directly compared to the ice core records.

In the dark polar winter, the animals aren't sleeping

Thu, 09/24/2015 - 13:25
You might expect that little happens in the Arctic Ocean during the cold and dark winter. But that just isn't so, according to researchers who have sampled the activities of many different species during three consecutive winters in Kongsfjorden, Svalbard.
