Eight ice caves in four Austrian federal states: A team of geologists has comprehensively documented the loss and gain of ice in Alpine ice caves over the last 2000 years for the first time. The geologists warn: The ice of smaller caves especially is in danger of disappearing in the near future and with it a valuable climate archive.

New research has mapped the DNA from more than 150 species of native rodents from across Australia, New Guinea and Melanesian islands, painting a clearer picture of how they're related and how they ended up spreading across the Pacific.

Researchers have documented that corals can pass mutations acquired during their lifetimes to their offspring, providing increased genetic diversity for potential evolutionary adaptation.

Sea ice levels in the Arctic Ocean are rapidly declining, due to global warming. Now, to understand and forecast the growth and decay of the ice, researchers have conducted a survey in the Arctic Ocean to investigate the influence of ocean heat on sea ice in the ice-ocean boundary layer. Their findings provide insights into the mechanisms of Arctic sea ice decline for making accurate predictions in the future regarding the global climate.

A new study highlights that global demand for sulfuric acid is set to rise significantly from '246 to 400 million tons' by 2040 -- a result of more intensive agriculture and the world moving away from fossil fuels. A projected shortage of sulfuric acid, a crucial chemical in our modern industrial society, could stifle green technology advancement and threaten global food security, according to a new study.

A new study investigates how different mammals react to climate change. Animals that live for a long time and/or produce less offspring -- like bears and bison -- are more resilient than small animals with a short life -- like mice and lemmings.

Scientists have confirmed their previous observations that rising temperatures increase the sound of snapping shrimp, a tiny crustacean found in temperate and tropical coastal marine environments around the world.

Comprehensive data from several seasons of field research in the Alaskan Arctic will address uncertainties in Earth-system and climate-change models about snow cover across the region and its impacts on water and the environment.

New research based on an expedition to the icy waters off Greenland reveals soaring levels of antifreeze proteins in a species of tiny snailfish, underlying the importance of this unique adaptation to life in sub-zero temperatures. The study also warns that warming oceanic temperatures in the Arctic could pose a threat to these highly specialized fishes.

Thawing Arctic hillsides release a significant amount of organic carbon that has been locked in frozen ground for thousands of years but which now can contribute to an already warming climate, according to new research. The finding comes from the study of hillsides in a far north region of Russia, where the researchers also found a significant and rapid increase of collapsed hillsides. The collapses feature landslides that gradually expose more of the permafrost for thawing -- and more carbon for release.

Across the United States, local wind and solar jobs can fully replace the coal-plant jobs that will be lost as the nation's power-generation system moves away from fossil fuels in the coming decades, according to a new study.

The restoration of grassland ecosystems may need more of a guided, hands-on approach over time, according to a new review of global conservation efforts.

Tropical coastal ecosystems are among the most biodiverse areas on Earth. And they're also on the front lines of effects caused by human activity. That's why it's becoming increasingly important, especially as human populations increase, to manage the impacts of runoff and wastewater that flow into the sea.

The northern and central Great Barrier Reef have recorded their highest amount of coral cover since the Australian Institute of Marine Science (AIMS) began monitoring 36 years ago. However, average coral cover in the southern region decreased due to ongoing crown-of-thorns starfish outbreaks. While the Reef experienced its fourth major bleaching event in the past seven years this year, it didn't reach the intensity of earlier events and was not expected to lead to mass coral mortality.

As warming ocean temperatures threaten the existence of coral reefs, scientists have successfully used an extremely high-resolution computer simulation of ocean circulation to identify possible 'thermal refugia' where these biodiverse ecosystems are more likely to survive.

A research team has created a computer modelling program to help scientists predict the effect of climate damage and eventual restoration plans on coral reefs around the globe. This is a critical objective because climate change is killing many coral species and can lead to the collapse of entire coral reef ecosystems, according to researchers.

A new study reveals that introduced donkeys and indigenous pumas are helping to resurrect extinct food webs in Death Valley.
