Three Gorges Dam: Friend or foe of riverine greenhouse gases?
Dams are conventionally regarded as emitters of GHGs in large rivers. A team from Peking University of China, however, has disrupted this perception, based on whole system thinking applied to the Three Gorges Dam (TGD) on the Yangtze River in China......»»
Beaver activity in the Arctic linked to increased emission of methane greenhouse gas
The climate-driven advance of beavers into the Arctic tundra is likely causing the release of more methane—a greenhouse gas—into the atmosphere......»»
Study suggests energy-efficient route to capturing and converting carbon dioxide
In the race to draw down greenhouse gas emissions around the world, scientists at MIT are looking to carbon-capture technologies to decarbonize the most stubborn industrial emitters......»»
International report confirms record-high greenhouse gases, global sea levels in 2022
Greenhouse gas concentrations, global sea level and ocean heat content reached record highs in 2022, according to the 33rd annual State of the Climate report......»»
Methane emissions in LA are decreasing more slowly than previously estimated
Methane is a powerful greenhouse gas, 80 times more potent at warming the atmosphere than carbon dioxide. In 2014, a California law required statewide methane emissions to be cut by 40% by 2030 from 2013 levels. Currently, the local natural gas utili.....»»
A Billion-Dollar Plan to Fix Farm Emissions Might Make Things Worse
Agriculture is a huge source of greenhouse gas emissions, so the US is getting serious about reform. But some scientists say current efforts are misguided......»»
Zimbabwe"s climate action plan: A win for the environment, health and energy
The dumping of billions of tons of carbon dioxide and other greenhouse gases into the atmosphere yearly is already having a devastating impact around the world. This includes widespread flooding and droughts, raging wildfires, heat waves and record t.....»»
Study quantifies link between greenhouse gases, polar bear survival
Polar bears have long symbolized the dangers posed by climate change, as rising temperatures melt away the Arctic sea ice they depend upon for survival......»»

Study connects greenhouse gas emissions to polar bear population declines
New research from the University of Washington and Polar Bears International in Bozeman, Montana, quantifies the relationship between greenhouse gas emissions and the survival of polar bear populations. The paper, published online Aug. 31 in Science,.....»»
Idaho"s Silver Valley is still at risk 50 years after mine fire caused largest lead-poisoning case in US history
On Sept. 3, 1973, a fire swept through the baghouse of the Bunker Hill mine in Idaho's Silver Valley. The building was designed to filter pollutants produced by smelting, the melting of rocks that separates metal from its ore. The gases produced in t.....»»
Climate poses "high risk" for Europe"s ski resorts
At current rates of greenhouse gas emissions, which would see Earth's surface warm nearly three degrees Celsius above pre-industrial levels, 90 percent of Europe's ski resorts will eventually face critical shortages of natural snow, researchers said.....»»
UN-backed deforestation carbon credits failing: study
Only a small fraction of the forest-based carbon credits that companies and governments have purchased to offset their greenhouse gas emissions actually help prevent deforestation, according to new research......»»
Greenhouse gases are changing air flow over the Pacific Ocean, raising Australia"s risks of extreme weather
After a rare three-year La Niña event brought heavy rain and flooding to eastern Australia in 2020-22, we're now bracing for the heat and drought of El Niño at the opposite end of the spectrum......»»
It"s so metal: Scientists confirm nickel plays a key role in an ancient chemical reaction
Carbon dioxide (CO2) is the most abundant greenhouse gas causing climate change but has existed on Earth long before humans started releasing it into the atmosphere at unprecedented levels. As such, some of the planet's earliest organisms evolved to.....»»
Climate change is making debt more expensive—new study
Earth is overheating due to the greenhouse gas emissions from burning fossil fuels. This is "the biggest market failure the world has seen" according to economist Nicholas Stern. The rational behavior of companies that pollute by making profitable co.....»»
Researchers develop novel technique for sniffing out toxic algae blooms
Researchers at Oregon State University have developed a new way to monitor the danger associated with algae blooms: "sniffing" the water for gases associated with toxins......»»
Study reveals America"s wealthiest 10% responsible for 40% of US greenhouse gas emissions
A new study, led by the University of Massachusetts Amherst, reveals that the wealthiest Americans, those whose income places them in the top 10% of earners, are responsible for 40% of the nation's total greenhouse gas emissions. The study, published.....»»
Mapping methane emissions from rivers around globe reveals surprising sources
Freshwater ecosystems account for half of global emissions of methane, a potent greenhouse gas that contributes to global warming. Rivers and streams, especially, are thought to emit a substantial amount of that methane, but the rates and patterns of.....»»
Scientists say deepening Arctic snowpack drives greenhouse gas emissions
Human-caused climate change is shortening the snow cover period in the Arctic. But according to new research led by Earth system scientists at the University of California, Irvine, some parts of the Arctic are getting deeper snowpack than normal, and.....»»
New paint gives extra insulation, saving on energy, costs, and carbon emissions
Stanford University scientists have invented a new kind of paint that can keep homes and other buildings cooler in the summer and warmer in the winter, significantly reducing energy use, costs, and greenhouse gas emissions......»»
