Republicans more persuasive than scientists on climate change Regardless of political affiliation, people are more likely to believe facts about climate change when they come from Republicans speaking against what has become a partisan interest in this country, says a new UConn study.
Carbon dioxide as a raw material Researchers at the Ruhr-Universität Bochum have found a way to turn climate-damaging CO2 into an alcohol that could serve as a raw material for the chemical industry - without producing large amounts of salt waste that usually arise. The reaction mec
Surviving climate change, then and now An archeological dig in Italy reveals that prehistoric humans made it through a major natural disaster by cooperating with each other -- and that's a lesson for our future.
Mountain erosion may add CO2 to the atmosphere Scientists have long known that steep mountain ranges can draw carbon dioxide (CO2) out of the atmosphere -- as erosion exposes new rock, it also starts a chemical reaction between minerals on hill slopes and CO2 in the air, 'weathering' the rock and usin
The 100th meridian, where the Great Plains begin, may be shifting Nearly a century and a half after explorer John Wesley Powell zeroed in on the 100th meridian west as the dividing line between the humid east and arid west of the United States, researchers say he was right -- but that climate change is now moving the li

Once we can capture CO2 emissions, here's what we could do with it The carbon dioxide (CO2) emitted from power plants each year doesn't have to go into the atmosphere. Researchers are optimistic that within the next decade we will be able to affordably capture CO2 waste and convert it into useful molecules for feedstock,
Fifth International Symposium on Arctic Research The Fifth International Symposium on Arctic Research (ISAR-5) was held in Tokyo from Jan. 15-18, 2018, the largest of Asia's non-Arctic nations. The participants included 344 persons from 18 countries and regions, with 100 young researchers as well. Resea
Norfolk's iconic swallowtail butterfly at risk from climate change New research reveals that Norfolk's butterflies, bees, bugs, birds, trees and mammals are at major risk from climate change as temperatures rise.

Reconciling Paris Agreement goals for temperature, emissions As society faces the challenge of limiting warming to no more than 2 degrees Celsius, new research finds an apparent contradiction: Achieving that goal doesn't necessarily require cutting greenhouse gas emissions to zero, as called for in the Paris Agreem
Bacteria eats greenhouse gas with a side of protein With the ability to leech heavy metals from the environment and digest a potent greenhouse gas, methanotrophic bacteria pull double duty when it comes to cleaning up the environment. But before researchers can explore potential conservation applications,
The explosive consequences of cow burps (video) Cows burp up more gas than you might think possible when they're digesting grass. Most of that gas is methane, a potent greenhouse gas, which is bad news for the planet. This video from Reactions explains why the chemistry of cow guts is such a busy area

Amazon deforestation is close to tipping point Scientists considered climate change and indiscriminate use of fire to calculate that deforestation rates ranging from 20 percent to 25 percent could turn Amazon's hydrological cycle unable to support its ecosystem.
Environmentally friendly cattle production (really) When cattle congregate, they're often cast as the poster animals for overgrazing, water pollution and an unsustainable industry. While some of the criticism is warranted, cattle production -- even allowing herds to roam through grasslands and orchards --
Climate change threatens world's largest seagrass carbon stores Shark Bay seagrass carbon storage hotspot suffers alarming losses after a devastating marine heat wave, according to a study led by ICTA-Universitat Autònoma de Barcelona researchers. The loss of seagrass would have released up to nine million metric
Glacier mass loss: Past the point of no return Researchers from the Universities of Bremen and Innsbruck show in a recent study that the further melting of glaciers cannot be prevented in the current century -- even if all emissions were stopped now. However, due to the slow reaction of glaciers to cl

Wandering greenhouse gas On the seafloor of the shallow coastal regions north of Siberia, microorganisms produce methane when they break down plant remains. If this greenhouse gas finds its way into the water, it can also become trapped in the sea ice that forms in these coastal
Land under water: Estimating hydropower's land use impacts One of the key ways to combat global climate change is to boost the world's use of renewable energy. But even green energy has its environmental costs. A new approach describes just how hydropower measures up when it comes to land use effects.

The technique -- which could prove as revolutionary as fossil pollen and charcoal markers -- can provide info
Tropical trees use unique method to resist drought Tropical trees in the Amazon Rainforest may be more drought resistant than previously thought, according to a new study by researchers at the University of California, Riverside.That's good news, since the Amazon stores about 20 percent of all carbon in t
Land use change has warmed the Earth's surface Recent changes to vegetation cover are causing the Earth's surface to heat up. Activities like cutting down evergreen forests for agricultural expansion in the tropics create energy imbalances that lead to higher local surface temperatures and contribute
At last, butterflies get a bigger, better evolutionary tree Butterflies offer key insights into community ecology, how species originate and evolve, climate change and interactions between plants and insects. But a comprehensive map of how butterflies are related to each other has been lacking -- until now.

Why did gas hydrates melt at the end of the last ice age? Large amounts of the greenhouse gas methane are locked up as solid gas hydrates in the continental slopes of ocean margins. Their stability depends on low temperatures and high pressure. However, other factors that influence gas hydrate stability are not
