Spurred by a warming climate, daily record high temperatures occurred twice as often as record lows over the last decade across the continental United States, new research shows.
The ratio of record highs to lows is likely to increase dramatically in coming decades if emissions of greenhouse gases continue to climb.
Results of the research, by authors [...]

New technologies and policies that save energy, remove atmospheric carbon and limit greenhouse gas emissions are needed to fight global climate change — but face daunting technological, economic and political hurdles, a Michigan State University scientist said.
The good news: Basic actions taken by everyday people can yield fast savings at low cost, according to MSU [...]

Beef farmers can breathe easier thanks to University of Alberta researchers who have developed a formula to reduce methane gas in cattle.
By developing equations that balance starch, sugar, cellulose, ash, fat and other elements of feed, a Canada-wide team of scientists has given beef producers the tools to lessen the methane gas their cattle produce [...]

Combating climate change may not be a question of who will carry the burden but could instead be a rush for the benefits, according to new economic modeling presented today at “Climate Change: Global Risks, Challenges & Decisions” hosted by the University of Copenhagen.
Contrary to current cost models for lowering greenhouse gas emissions and fighting [...]

A gas used for fumigation has the potential to contribute significantly to future greenhouse warming, but because its production has not yet reached high levels there is still time to nip this potential contributor in the bud, according to an international team of researchers.
Scientists at MIT, the Scripps Institution of Oceanography in San Diego and [...]

Animal feeding operations are an important emission source of air pollutants including methane and carbon dioxide — known greenhouse gases. Recent inventories suggest that animal manure makes a significant contribution to global methane emissions. As a consequence, greenhouse gas emissions can potentially become a limiting factor in the development and sustainability of animal production and [...]

Researchers at MIT’s Center for Energy and Environmental Policy Research have produced a report concerning key design issues of proposed “cap-and-trade” programs that are under consideration in the United States as a way of curbing greenhouse gas emissions. The first contribution of the three-part study found that, based on an examination of the European Union’s [...]

The newest analysis of trace gases trapped in Antarctic ice cores now provide a reasonable view of greenhouse gas concentrations as much as 800,000 years into the past, and are further confirming the link between greenhouse gas levels and global warming, scientists reported today in the journal Nature.
They also show that during that entire period [...]

Scientists at Newcastle University have pioneered breakthrough technology in the fight to cut greenhouse gases.
The Newcastle University team, led by Michael North, Professor of Organic Chemistry, has developed a highly energy-efficient method of converting waste carbon dioxide (CO2) into chemical compounds known as cyclic carbonates.
The team estimates that the technology has the potential to use [...]

The old adage, “We are what we eat,” may be the latest recipe for success when it comes to curbing the perils of global climate warming. Despite the recent popular attention to the distance that food travels from farm to plate, aka “food miles,” Carnegie Mellon researchers Christopher L. Weber and H. Scott Matthews argue [...]

A new, high-resolution, interactive map of U.S. carbon dioxide emissions from fossil fuels has found that the emissions aren’t all where we thought.
“For example, we’ve been attributing too many emissions to the northeastern United States, and it’s looking like the southeastern U.S. is a much larger source than we had estimated previously,” says Kevin Gurney, [...]

Methane, a potent greenhouse gas, is emitted in great quantities as bubbles from seeps on the ocean floor near Santa Barbara. About half of these bubbles dissolve into the ocean, but the fate of this dissolved methane remains uncertain. Researchers at the University of California, Santa Barbara have discovered that only one percent of this [...]

A new species of bacteria discovered living in one of the most extreme environments on Earth could yield a tool in the fight against global warming.
In a paper published today in the prestigious science journal Nature, University of Calgary biology professor Peter Dunfield and colleagues describe the methane-eating microorganism they found in the geothermal field [...]
