Coastal permafrost more susceptible to climate change than previously thought

Fri, 10/23/2020 - 21:10
Research has found permafrost to be mostly absent throughout the shallow seafloor along a coastal field site in northeastern Alaska. That means carbon can be released from coastline sources much more easily than previously thought.

Soil fungi act like a support network for trees

Thu, 10/22/2020 - 19:31
New research is first to show that growth rate of adult trees is linked to fungal networks colonizing their roots.

Ice loss likely to continue in Antarctica, even if climate change is brought under control, study finds

Thu, 10/22/2020 - 15:33
A new study has revealed that ice loss in Antarctica persisted for many centuries after it was initiated and is expected to continue.

Genome sequencing shows climate barrier to spread of Africanized bees

Wed, 10/21/2020 - 23:39
Since the 1950s, 'Africanized' honeybees have spread north and south across the Americas until apparently coming to a halt in California and northern Argentina. Now genome sequencing of hundreds of bees from the northern and southern limits shows a gradual decline in African ancestry across hundreds of miles, rather than an abrupt shift.

Turbulent era sparked leap in human behavior, adaptability 320,000 years ago

Wed, 10/21/2020 - 21:09
The first analysis of a sedimentary drill core representing 1 million years of environmental history in the East African Rift Valley shows that at the same time early humans were abandoning old tools in favor of more sophisticated technology and broadening their trade, their landscape was experiencing frequent fluctuations in vegetation and water supply that made resources less reliably available. The findings suggest that instability in their landscape was a key driver of human adaptability.

Protected areas help waterbirds adapt to climate change

Wed, 10/21/2020 - 20:01
Climate change pushes species distribution areas northward. However, the expansion of species ranges is not self-evident due to e.g. habitat degradation and unsustainable harvesting caused by human activities. A new study suggests that protected areas can facilitate wintering waterbird adaptation to climate warming by advancing their range shifts towards north.

Management of exploited transboundary fish stocks requires international cooperation

Wed, 10/21/2020 - 18:23
Marine fish species are migratory in nature and not respectful of human-made territorial boundaries, which represents a challenge for fisheries management as policies tend to focus at the national level. With an average catch of 48 million tonnes per year, and USD $77 billion in annual fishing revenue, these species support critical fisheries, and require international cooperation to manage.

New sediment archive for historical climate research

Wed, 10/21/2020 - 18:23
Geological investigations of low-temperature young deposits on the Styrian Erzberg provide paleoclimatology with new data on the Earth's history and its development.

What cold lizards in Miami can tell us about climate change resilience

Wed, 10/21/2020 - 15:51
When temperatures go below a critical limit, sleeping lizards lose their grip and fall out of trees. But when researchers collected the scaled survivors of a record cold snap, they discovered that a Miami lizard community responded in an unexpected way: all of them could now tolerate cold temperatures down to about 42 degrees Fahrenheit, regardless of their species' previous ability to withstand cold.

The effects of wildfires and spruce beetle outbreaks on forest temperatures

Wed, 10/21/2020 - 15:51
Results indicate that wildfires may play a role in accelerating climate-driven species changes in mountain forests by compounding regional warming trends.

A new material for separating CO2 from industrial waste gases, natural gas, or biogas

Tue, 10/20/2020 - 20:56
With a new material, the greenhouse gas carbon dioxide (CO2) can be specifically separated from industrial waste gases, natural gas, or biogas, and thereby made available for recycling. The separation process is both energy efficient and cost-effective.

Lost and found: Geologists 'resurrect' missing tectonic plate

Tue, 10/20/2020 - 20:14
A team of geologists believes they have found the lost plate known as Resurrection in northern Canada by using existing mantle tomography images.

Microbial diversity below seafloor is as rich as on Earth's surface

Tue, 10/20/2020 - 20:13
For the first time, researchers have mapped the biological diversity of marine sediment, one of Earth's largest global biomes. The research team discovered that microbial diversity in the dark, energy-limited world beneath the seafloor is as diverse as in Earth's surface biomes.

Depths of the Weddell Sea are warming five times faster than elsewhere

Tue, 10/20/2020 - 17:55
Over the past three decades, the depths of the Antarctic Weddell Sea have warmed five times faster than the rest of the ocean at depths exceeding 2,000 meters.

Declines in shellfish species on rocky seashores match climate-driven changes

Tue, 10/20/2020 - 15:17
Mussels, barnacles, and snails are declining in the Gulf of Maine, according to a new article by biologists. Their 20-year dataset reveals that the populations' steady dwindling matches up with the effects of climate change on the region.

Tropical cyclones moving faster in recent decades

Mon, 10/19/2020 - 23:49
Tropical cyclones, regionally known as hurricanes or typhoons, have been moving across ocean basins faster since 1982, according to a new study.

Tiny beetles a bellwether of ecological disruption by climate change

Mon, 10/19/2020 - 21:55
New research shows that as species across the world adjust where they live in response to climate change, they will come into competition with other species that could hamper their ability to keep up with the pace of this change.

Driver of the largest mass extinction in the history of the Earth identified

Mon, 10/19/2020 - 19:55
252 million years ago, at the transition from the Permian to the Triassic epoch, most of the life forms existing on Earth became extinct. Using latest analytical methods and detailed model calculations, scientists have now succeeded for the first time to provide a conclusive reconstruction of the geochemical processes that led to this unprecedented biotic crisis.

Paper recycling must be powered by renewables to save climate

Mon, 10/19/2020 - 18:21
The study found that greenhouse gas emissions would increase by 2050 if we recycled more paper, as current methods rely on fossil fuels and electricity from the grid.

A renewable solution to keep cool in a warming world

Mon, 10/19/2020 - 17:34
Month-after-month, year-after-year, the world continues to experience record high temperatures. In response to this and exacerbated by a growing global population, it is expected that air-conditioning demand will continue to rise. A new study explored the pros and cons of seawater air-conditioning as an alternative cooling solution.
