Turbulence creates ice in clouds

Fri, 11/08/2019 - 09:28
Vertical air motions increase ice formation in mixed-phase clouds. This correlation was predicted theoretically for a long time, but could now be observed for the first time in nature. Using laser and radar equipment, the team measured the vertical air velocity and ice formation in thin mixed-phase clouds.

Unless warming is slowed, emperor penguins will be marching towards extinction

Thu, 11/07/2019 - 15:07
Emperor penguins are some of the most striking and charismatic animals on Earth, but a new study has found that a warming climate may render them extinct by the end of this century.

Melting Arctic sea ice linked to emergence of deadly virus in marine mammals

Thu, 11/07/2019 - 10:29
Scientists have linked the decline in Arctic sea ice to the emergence of a deadly virus that could threaten marine mammals in the North Pacific, according to a study.

Scientists declare climate emergency, establish global indicators for effective action

Tue, 11/05/2019 - 09:44
A global coalition of scientists says 'untold human suffering' is unavoidable without deep and lasting shifts in human activities that contribute to greenhouse gas emissions and other factors related to climate change.

Changes in high-altitude winds over the South Pacific produce long-term effects

Tue, 11/05/2019 - 09:44
In the past million years, the high-altitude winds of the southern westerly wind belt, which spans nearly half the globe, didn't behave as uniformly over the Southern Pacific as previously assumed. Instead, they varied cyclically over periods of ca. 21,000 years. A new study has now confirmed close ties between the climate of the mid and high latitudes and that of the tropics in the South Pacific.

Sea levels to continue rising after Paris agreement emission pledges expire in 2030

Mon, 11/04/2019 - 14:56
Sea levels will continue to rise around the world long after current carbon emissions pledges made through the Paris climate agreement are met and global temperatures stabilize, a new study indicates.

Two million-year-old ice provides snapshot of Earth's greenhouse gas history

Wed, 10/30/2019 - 14:58
Two million-year old ice from Antarctica recently uncovered by a team of researchers provides a clearer picture into the connections between greenhouse gases and climate in ancient times and will help scientists understand future climate change.

Alongside Ötzi the Iceman: A bounty of ancient mosses and liverworts

Wed, 10/30/2019 - 14:14
Buried alongside the famous Ötzi the Iceman are at least 75 species of bryophytes -- mosses and liverworts -- which hold clues to Ötzi's surroundings, according to a new study.

Reframing Antarctica's meltwater pond dangers to ice shelves and sea level

Fri, 10/25/2019 - 12:04
On Antarctica, meltwater ponds riddle a kilometer-thick, 10,000-year-old ice shelf, which shatters just weeks later. The collapse shocks scientists and unleashes the glacier behind the ice shelf, driving up sea level. A new study puts damage by meltwater ponds to ice shelves and the ensuing threat to sea level into cool, mathematical perspective.

Did an extraterrestrial impact trigger the extinction of ice-age animals?

Fri, 10/25/2019 - 10:03
Based on research at White Pond near Elgin, South Carolina, archaeologists present new evidence of a controversial theory that suggests an extraterrestrial body crashing to Earth almost 13,000 years ago caused the extinction of many large animals and a probable population decline in early humans.

The shelf life of pyrite

Thu, 10/24/2019 - 11:26
What exactly triggers the increase in carbon dioxide concentrations that causes the transition from a glacial stage to a warm stage is not fully understood. Scientists have developed a new model in which the weathering of pyrite, a common mineral containing sulfur, plays a key role.

Mapping international drug use through the world's largest wastewater study

Wed, 10/23/2019 - 08:34
A seven-year project monitoring illicit drug use in 37 countries via wastewater samples shows that cocaine use was skyrocketing in Europe in 2017 and Australia had a serious problem with methamphetamine.

Satellite data used to calculate snow depth in mountain ranges

Tue, 10/22/2019 - 11:11
Bioscience engineers have developed a method to measure the snow depth in all mountain ranges in the Northern Hemisphere using satellites. This technique makes it possible to study areas that cannot be accessed for local measurements, such as the Himalayas.

Catastrophic events carry forests of trees thousands of miles to a burial at sea

Mon, 10/21/2019 - 17:33
While studying sediments in the Bay of Bengal, an international team finds evidence dating back millions of years that catastrophic events likely toppled fresh trees from their mountain homes on a long journey to the deep sea. The discovery may add to models of the Earth's carbon cycle.

Lead pollution from Native Americans attributed to crushing galena for glitter paint

Mon, 10/21/2019 - 13:47
A new study of Native American use of galena increases understanding of how they were using the land and its resources.

Antarctic ice cliffs may not contribute to sea-level rise as much as predicted

Mon, 10/21/2019 - 12:50
Researchers report that in order for a 90-meter ice cliff to collapse entirely, the ice shelves supporting the cliff would have to break apart extremely quickly, within a matter of hours -- a rate of ice loss that has not been observed in the modern record.

Information theory as a forensics tool for investigating climate mysteries

Thu, 10/17/2019 - 06:55
During Earth's last glacial period, temperatures on the planet periodically spiked dramatically and rapidly. A new article suggests that mathematics from information theory could offer a powerful tool for analyzing and understanding these mysterious events.

Inside the fuel cell: Imaging method promises industrial insight

Tue, 10/15/2019 - 10:53
Hydrogen-containing substances are important for many industries, but scientists have struggled to obtain detailed images to understand the element's behavior. Researchers now demonstrate the quantification of hydrogen for different states of water -- i.e., liquid, frozen and supercooled -- for applications to eco-friendly fuel cells.

Population aging to create pockets of climate vulnerability in the US

Fri, 10/11/2019 - 10:22
Population aging projections across the US show a divide between cities and rural areas, which could lead to pockets of vulnerability to climate change.
