Turbulence affects aerosols and cloud formation

Wed, 09/16/2020 - 22:48
Turbulent air in the atmosphere affects how cloud droplets form. New research in a cloud chamber changes the way clouds, and therefore climate, are modeled.

Colorado's famous aspens expected to decline due to climate change

Wed, 09/16/2020 - 20:08
Using computer modeling, researchers simulated how the distribution of quaking aspen, a native tree known for its brilliant yellow and orange foliage in fall and the sound of its trembling leaves, will change amid rising temperatures over the next 100 years.

Marine animals live where ocean is most breathable, ranges may shrink with climate change

Wed, 09/16/2020 - 18:35
New research shows that a wide variety of marine animals -- from vertebrates to crustaceans to mollusks -- already inhabit the maximum range of breathable ocean that their physiology will allow. The findings provide a warning about climate change: Since warmer waters will harbor less oxygen, some stretches of ocean that are breathable today for a given species may not be in the future.

Siberia's permafrost erosion has been worsening for years

Wed, 09/16/2020 - 18:34
The Arctic is warming faster than any other region on the planet. As a result, permafrost that is thousands of years old is now being lost to erosion. As measurements gathered on the Lena River show, the scale of erosion is alarming.

Can pumping up cold water from deep within the ocean halt coral bleaching?

Wed, 09/16/2020 - 18:34
Rising ocean temperatures cause marine heat waves, which place stress on living coral animals, as well as the photosynthetic algae on which they depend for energy. A new study is showing potential for the use of artificial upwelling (AU)-- or the application of cooler, deep water -- as a way to mitigate the thermal stress on corals.

Mercury concentrations in Yukon river fish could surpass EPA criterion by 2050

Wed, 09/16/2020 - 18:34
The concentration of mercury in the fish in Alaska's Yukon River may exceed the EPA's human health criterion by 2050 if greenhouse gas emissions that cause global warming are not constrained, according to new research.

Satellite images display changes in the condition of European forests

Tue, 09/15/2020 - 17:59
The forest canopy, the closed vegetation cover consisting of treetops, is rapidly declining according to new research. The team used satellite images, to create the first high-resolution map of canopy openings in Europe's forests and reached the conclusion that the canopy of more than 36 million forest areas has been lost over the past 30 years.

Ocean algae get 'coup de grace' from viruses

Tue, 09/15/2020 - 16:01
Scientists have long believed that ocean viruses always quickly kill algae, but new research shows they live in harmony with algae and viruses provide a 'coup de grace' only when blooms of algae are already stressed and dying. The study will likely change how scientists view viral infections of algae, also known as phytoplankton - especially the impact of viruses on ecosystem processes like algal bloom formation (and decline) and the cycling of carbon and other chemicals on Earth.

NASA monitors carbon monoxide from California wildfires

Tue, 09/15/2020 - 04:29
The observations from Earth orbit show high-altitude concentrations of the gas that are more than 10 times typical amounts.

Ancient volcanoes once boosted ocean carbon, but humans are now far outpacing them

Tue, 09/15/2020 - 00:29
A new study of an ancient period that is considered the closest natural analog to the era of modern human carbon emissions has found that massive volcanism sent great waves of carbon into the oceans over thousands of years -- but that nature did not come close to matching what humans are doing today.

Antarctica: Cracks in the ice

Mon, 09/14/2020 - 22:11
West Antarctica's Pine Island Glacier and Thwaites Glacier have been undergoing rapid changes, with potentially major consequences for rising sea levels. However, the processes that underlie these changes and their impact on these ice sheets have not been fully charted. One of these processes has now been described in detail: the emergence and development of damage/cracks in part of the glaciers and how this process reinforces itself.

Dams exacerbate the consequences of climate change on river fish

Mon, 09/14/2020 - 20:19
A potential response of river fish to environmental changes is to colonize new habitats. But what happens when dams and weirs restrict their movement? And are native and alien species similarly affected?

ARPA-type funding gives green technology an 'innovation advantage', study finds

Mon, 09/14/2020 - 18:59
Startups funded by the U.S. agency ARPA-E file patents at twice the rate of similar cleantech firms. The United Kingdom should trial its own climate-focused ARPA as part of COVID-19 recovery package, argue experts.

Mediterranean and tropical biodiversity most vulnerable to human pressures

Mon, 09/14/2020 - 18:22
Animals in tropical and Mediterranean areas are the most sensitive to climate change and land use pressures, finds a new study.

Arctic transitioning to a new climate state

Mon, 09/14/2020 - 18:22
The fast-warming Arctic has started to transition from a predominantly frozen state into an entirely different climate with significantly less sea ice, warmer temperatures, and more rain, according to a comprehensive new study of Arctic conditions.

Climate change triggers migration, particularly in middle-income countries

Mon, 09/14/2020 - 18:22
Environmental hazards affect populations worldwide and can drive migration under specific conditions. Changes in temperature levels, increased rainfall variability, and rapid-onset disasters, such as tropical storms, are important factors as shown by a new study. Environmental migration is most pronounced in middle-income and agricultural countries but weaker in low-income countries, where populations often lack resources needed for migration.

Volcanic ash may have a bigger impact on the climate than we thought

Fri, 09/11/2020 - 18:08
Volcanic ash shuts down air traffic and can sicken people. But a new study suggests that it may also be more important for Earth's climate than scientists once thought.

More than 90 percent of protected areas are disconnected

Fri, 09/11/2020 - 16:30
Ongoing land clearing for agriculture, mining and urbanization is isolating and disconnecting Earth's protected natural areas from each other, a new study shows.

Climate change recasts the insect communities of the Arctic

Fri, 09/11/2020 - 16:30
Researchers have exposed major changes taking place in the insect communities of the Arctic. Their study reveals how climate change is affecting small but important predators of other insects, i.e. parasitoids.

Heated rivalries for pollinators among Arctic plants

Fri, 09/11/2020 - 16:30
Insect pollination is as important to Arctic plants as it is to plants further south. When flowers abound, the plants have to compete for pollinators. Researchers reveal that higher temperatures cause the flowering periods of different plant species to pile up in time. As a consequence, climate change may affect the competitive relationships of plants.
