In South Africa, tiny primates could struggle to adapt to climate change

University of Colorado Boulder — Tue, 07 May 2024 17:05:10 EST

Researchers led by CU Boulder primatologist Michelle Sauther walked the paths of the Lajuma Research Centre in South Africa at night, keeping an eye out for the glowing eyes of galago primates, or bushbabies. The team's findings reveal troubling hints about how small animals may adapt to extreme temperatures.

Demystifying the complex nature of Arctic clouds

University of Miami — Fri, 03 May 2024 11:05:56 EST

A team of University of Miami scientists and others recently spent weeks in the Arctic region studying marine cold-air outbreaks and how the clouds they produce can lead to extreme weather events and may be interacting with the rapidly warming Arctic.

Why did Earth once turn into a giant frozen snowball? Australian scientists now have an answer

University of Sydney — Thu, 08 Feb 2024 12:05:49 EST

Australian geologists have used plate tectonic modelling to determine what most likely caused an extreme ice-age climate in Earth's history, more than 700 million years ago.

UC Irvine scientists say deepening Arctic snowpack drives greenhouse gas emissions

University of California, Irvine — Wed, 16 Aug 2023 11:05:30 EST

Human-caused climate change is shortening the snow cover period in the Arctic.

Marine fossils are a reliable benchmark for degrading and collapsing ecosystems

Florida Museum of Natural History — Tue, 11 Jul 2023 13:25:30 EST

Biologists attempting to conserve and restore denuded environments are limited by their scant knowledge of what those environments looked like before the arrival of humans.

About 13,000 years ago, the water outflow from the Mediterranean to the Atlantic Ocean was twice that of today's

Universitat de Barcelona — Tue, 16 May 2023 11:55:52 EST

About 13,000 years ago, a climate crisis caused a global drop in temperatures in the northern hemisphere. This episode of intense cold, known as the Younger Dryas, also caused severe aridity across the Mediterranean basin, which had a major impact on terrestrial and marine ecosystems.

UC Irvine, NASA JPL researchers discover a cause of rapid ice melting in Greenland

University of California, Irvine — Mon, 08 May 2023 16:00:14 EST

While conducting a study of Petermann Glacier in northwest Greenland, researchers at the University of California, Irvine and NASA's Jet Propulsion Laboratory uncovered a previously unseen way in which the ice and ocean interact. The glaciologists said their findings could mean that the climate community has been vastly underestimating the magnitude of future sea level rise caused by polar ice deterioration.

Researchers discover that the ice cap is teeming with microorganisms

Aarhus University — Tue, 02 May 2023 12:50:26 EST

There are no plants, and only very few animals: people rarely come here. The large glaciers in Greenland have long been perceived as ice deserts. Gigantic ice sheets where conditions for life are extremely harsh.

Large animals travel more slowly because they can't keep cool

PLOS — Tue, 18 Apr 2023 14:00:00 EST

Whether an animal is flying, running or swimming, its traveling speed is limited by how effectively it sheds the excess heat generated by its muscles, according to a new study led by Alexander Dyer from the German Centre for Integrative Biodiversity Research (iDiv) and the Friedrich Schiller University Jena, Germany published April 18th in the open access journal PLOS Biology.

How to prepare for ocean acidification, a framework

California Academy of Sciences — Tue, 28 Mar 2023 12:00:29 EST

In a paper published today in the journal Environmental Research Letters, an international research team composed of scientists affiliated with more than a dozen institutions, including the California Academy of Sciences, propose a first-of-its-kind framework for governments around the world to evaluate their preparedness for--and guide future policies to address--ocean acidification, among the most dire threats to marine ecosystems.

Sea ice will soon disappear from the Arctic during the summer months - and it has happened before

Aarhus University — Wed, 22 Mar 2023 10:50:50 EST

The "Last Ice Area" north of Greenland and Canada is the last sanctuary of all-year sea ice in this time of rising temperatures caused by climate change.

Climate Change Alters a Human-Raptor Relationship

Cornell University — Tue, 14 Mar 2023 07:00:13 EST

Bald Eagles and dairy farmers exist in a mutually beneficial relationship in parts of northwestern Washington State. According to a new study, this "win-win" relationship has been a more recent development, driven by the impact of climate change on eagles' traditional winter diet of salmon carcasses, as well as by increased eagle abundance following decades of conservation efforts.

Ocean Surface Tipping Point Could Accelerate Climate Change

University of Texas at Austin, Jackson School of Geosciences — Fri, 03 Mar 2023 08:45:21 EST

The oceans help to limit global warming by soaking up carbon dioxide emissions. But scientists have discovered that intense warming in the future could lessen that ability, leading to even more severe warming.

Monitoring an 'anti-greenhouse' gas: Dimethyl sulfide in Arctic air

Hokkaido University — Tue, 31 Jan 2023 13:15:23 EST

Data stored in ice cores dating back 55 years bring new insight into atmospheric levels of a molecule that can significantly affect weather and climate.

Kill dates for re-exposed black mosses

Geological Society of America (GSA) — Thu, 26 Jan 2023 13:15:09 EST

In their new paper for the Geological Society of America journal Geology, Dulcinea Groff and colleagues used radiocarbon ages (kill dates) of previously ice-entombed dead black mosses to reveal that glaciers advanced during three distinct phases in the northern Antarctic Peninsula over the past 1,500 years.

A Climate Change Cautionary Tale: Summer Heatwaves, Low Oxygen Proves Deadly for Bay Scallops as Fishery Collapses in New York

Stony Brook University — Thu, 19 Jan 2023 09:55:13 EST

A new study by Stony Brook University researchers published in the journal Global Change Biology demonstrates that warming waters and heat waves have contributed to the loss of an economically and culturally important fishery, the production of bay scallops.
