Lower methane emissions when permafrost disappears
Thawing permafrost in the Arctic does not always have to lead to increased emissions of the greenhouse gas methane. When thawed soil dries up, emissions can decline instead. A new study at the University of Gothenburg demonstrates this......»»
Water overuse in Brazil"s MATOPIBA region could mean failure to meet up to 40% of local demand for crop irrigation
Considered one of the fastest-growing agricultural frontiers in Brazil, and the area with the highest greenhouse gas emissions in the Cerrado, Brazil's savanna-type biome, the region known as MATOPIBA, risks facing water shortages in the years ahead......»»
Study identifies promising materials for fusion reactors
Nuclear fusion could be an ideal solution to mankind's energy problem, guaranteeing a virtually limitless source of power without greenhouse gas emissions. But there are still huge technological challenges to overcome before getting there, and some o.....»»
Study finds 30% of regions worldwide achieve economic growth while reducing carbon emissions
More and more regions around the globe combine economic growth with reducing carbon emissions, researchers from the Potsdam Institute for Climate Impact Research and the University of Potsdam found......»»
Artificial intelligence: A double-edged sword for the environment?
As AI technology progresses, the energy demands of training complex AI models have surged, raising widespread concerns about associated carbon emissions. This rapid growth is fueled by global demand across industries and academia, leading to exponent.....»»
Small reductions to meat production in wealthier countries may help fight climate change
Scientists and environmental activists have consistently called for drastic reductions in meat production as a way to reduce emissions and, in doing so, combat climate change. However, a new analysis concludes that a smaller reduction, borne by wealt.....»»
Exploring how microbes in permafrost contribute to nitrous oxide emissions
Ecologist Christina Biasi is exploring the conditions under which tiny organisms contribute to permafrost soils emitting nitrous oxide. Her research could be essential for the development of future climate scenarios......»»
New research estimates carbon emissions from 22 million stream reaches across the US
Using a sophisticated new modeling approach, researchers at the University of Massachusetts Amherst have estimated carbon dioxide emissions from inland waters to 22 million U.S. lakes, rivers and reservoirs. It marks the first time this approach has.....»»
The world promised to tame methane: Emissions are still rising
Sitting in his cramped office in Paris, Manfredi Caltagirone admits that one of the world's highest-profile efforts to cut methane emissions so far isn't stopping the gas from escaping and warming the atmosphere......»»
Experiments find coral reefs can survive some climate change—with help
If carbon emissions are curbed and local stressors are addressed, coral reefs have the potential to persist and adapt over time. That's according to a study published in the Proceedings of the National Academy of Sciences by researchers at the Univer.....»»

Earth"s climate will keep changing long after humanity hits net-zero emissions. Our research shows why
The world is striving to reach net-zero emissions as we try to ward off dangerous global warming. But will getting to net-zero actually avert climate instability, as many assume?.....»»
Saturn"s moon Titan may have a 6-mile-thick crust of methane ice — could life be under there?

Protecting northern water supplies from toxic metals in thawing permafrost
As the climate warms and Arctic permafrost thaws, some of the toxic elements locked away in it are starting to emerge and could contaminate the water supplies that many northern communities rely on......»»
Researchers observe stick-slip phenomenon in carbon nanotube fibers
The shapes of simple polyatomic molecules such as carbon dioxide and methane are characterized by a specific symmetry depending on the manner of linking of the atoms. Nano- to micrometer-sized particles that mimic the shapes of such polyatomic molecu.....»»
Volcanic "cryptic carbon" emissions may be a hidden driver of Earth"s past climate
An international team of geoscientists led by a volcanologist at Rutgers University-New Brunswick has discovered that, contrary to present scientific understanding, ancient volcanoes continued to spew carbon dioxide into the atmosphere from deep with.....»»
Experimental setup simulates Arctic methane explosions
Russian researchers have developed an experimental setup that will help simulate gas-dynamic processes and predict explosions in Arctic soils......»»
Is it true that trees pollute the air?
Methane is the most famous volatile organic compound (VOC) in our atmosphere. This week, our host George Zaidan follows up on a Reactions subscriber's question about the 600 teragrams of a less famous VOC released every year: isoprene......»»

Report: Nations must close huge emissions gap in new climate pledges and deliver immediate action, or 1.5°C is lost
Nations must collectively commit to cutting 42% off annual greenhouse gas emissions by 2030 and 57% by 2035 in the next round of Nationally Determined Contributions (NDCs)—and back this up with rapid action—or the Paris Agreement's 1.5°C goal wi.....»»
Saturn"s moon Titan has insulating methane-rich crust up to six miles thick
Saturn's largest moon, Titan, is the only place other than Earth known to have an atmosphere and liquids in the form of rivers, lakes and seas on its surface. Because of its extremely cold temperature, the liquids on Titan are made of hydrocarbons li.....»»
