Greenland ice losses rising faster than expected

Science Daily - Tue, 12/10/2019 - 10:17
Greenland is losing ice seven times faster than in the 1990s and is tracking the Intergovernmental Panel on Climate Change's high-end climate warming scenario, which would see 40 million more people exposed to coastal flooding by 2100.

Could we cool Earth with an ice-free Arctic?

Science Daily - Tue, 12/10/2019 - 10:16
The Arctic region is heating up faster than any other place on Earth, and as more and more sea ice is lost every year, we are already feeling the impacts. Researchers explored strategies for cooling down the oceans in a world without this important cooling mechanism.

Last remaining glaciers in the Pacific will soon melt away

Science Daily - Mon, 12/09/2019 - 15:13
The last remaining tropical glaciers between the Himalayas and the Andes will disappear in the next decade -- and possibly sooner -- due to climate change, a new study has found. The glaciers in Papua, Indonesia, are ''the canaries in the coal mine'' for other mountaintop glaciers around the world, said one of the researchers.

The Antarctic: Data about the structure of the icy continent

Science Daily - Mon, 12/09/2019 - 12:20
Satellite data from the European Space Agency (ESA) has now been used as the basis for new insights on the deep structure of the continent Antarctica.

Some forests crucial for climate change mitigation, biodiversity

Science Daily - Mon, 12/09/2019 - 12:19
Researchers have identified forests in the western United States that should be preserved for their potential to mitigate climate change through carbon sequestration, as well as to enhance biodiversity.

Can Arctic 'ice management' combat climate change?

Science Daily - Thu, 12/05/2019 - 12:06
According to a much-debated geo-engineering approach, both sea-ice retreat and global warming could be slowed by using millions of wind-powered pumps, drifting in the sea ice, to promote ice formation during the Arctic winter.

Gulf of Mexico coral reefs to protect from storm surge in the future -- But will they?

Science Daily - Wed, 12/04/2019 - 16:03
Researchers used 120,000-year-old fossils to predict how Gulf of Mexico coral reefs will respond to climate change toward the end of this century.

Outlook for the polar regions in a 2-degrees-warmer world

Science Daily - Wed, 12/04/2019 - 13:49
With 2019 on pace as one of the warmest years on record, a major new study reveals how rapidly the Arctic is warming and examines global consequences of continued polar warming. The study reports that the Arctic has warmed by 0.75 degrees C in the last decade alone.

Long-distance timber trade underpinned the Roman Empire's construction

Science Daily - Wed, 12/04/2019 - 13:48
The ancient Romans relied on long-distance timber trading to construct their empire, according to a new study.

Seismologists see future in fiber optic cables as earthquake sensors

Science Daily - Wed, 12/04/2019 - 10:32
Each hair-thin glass fiber in a buried fiber optic cable contains tiny internal flaws -- and that's a good thing for scientists looking for new ways to collect seismic data in places from a busy urban downtown to a remote glacier.

Great Barrier Reef study shows how reef copes with rapid sea-level rise

Science Daily - Tue, 12/03/2019 - 10:45
A survey of coral reef cores on the Great Barrier Reef has revealed how it has responded to recent periods of rapid sea-level rise. The study, covering the past 9000 years, has revealed a system in delicate balance.

Drone images show Greenland ice sheet becoming more unstable as it fractures

Science Daily - Mon, 12/02/2019 - 18:04
The world's second-largest ice sheet, and the single largest contributor to global sea-level rise, is potentially becoming unstable because of fractures developing in response to faster ice flow and more meltwater forming on its surface.

Mystery of how early animals survived ice age

Science Daily - Mon, 12/02/2019 - 18:04
How did life survive the most severe ice age? A team has found the first direct evidence that glacial meltwater provided a crucial lifeline to eukaryotes during Snowball Earth, when the oceans were cut off from life-giving oxygen, answering a question puzzling scientists for years.

Sustaining roads with grape and agricultural waste

Science Daily - Mon, 12/02/2019 - 12:57
The US spends $5 billion a year to repair damages to road infrastructure from winter snow and ice control operations and the use of traditional deicers. A team of researchers is developing a more sustainable solution using grape skins and other agricultural waste.

Antarctic ice sheets could be at greater risk of melting than previously thought

Science Daily - Mon, 12/02/2019 - 11:46
Antarctica is the largest reservoir of ice on Earth -- but new research suggests it could be at greater risk of melting than previously thought.

Antarctica's thinning ice shelves causing more ice to move from land into sea

Science Daily - Mon, 12/02/2019 - 11:46
New study provides the first evidence that thinning ice shelves around Antarctica are causing more ice to move from the land into the sea.

Animals could help humans monitor oceans

Science Daily - Wed, 11/27/2019 - 20:51
Sharks, penguins, turtles and other seagoing species could help humans monitor the oceans by transmitting oceanographic information from electronic tags.

Nine climate tipping points now 'active,' warn scientists

Science Daily - Wed, 11/27/2019 - 15:14
More than half of the climate tipping points identified a decade ago are now 'active,' a group of leading scientists have warned.

Nearly 40% of plant species are very rare and are vulnerable to climate change

Science Daily - Wed, 11/27/2019 - 15:12
Almost 40 percent of global flora is categorized as 'exceedingly rare,' and these species are most at risk of extinction by human development and as the climate continues to change, according to new research.

Wolfe Creek Crater younger than previously thought

Science Daily - Thu, 11/21/2019 - 11:18
Wolfe Creek Crater, one of the world's largest meteorite craters, is much younger than previously thought.
