Climate engineering is unlikely to provide an effective or practical solution to slowing global warming, according to a new study. Reducing the release of carbon remains the only likely answer to tackling climate change ahead of fanciful ...

Pushing the needle back on billowing carbon dioxide emissions may be necessary to avoid catastrophic warming. But for those who are squeamish about drastically engineering the climate by seeding algae blooms or spraying aerosols to form clouds, ...

Each year there are more extreme weather events not only in the US but all over the world. Most scientists agree that, as more carbon dioxide is pumped into the air and the gaseous composition of the atmosphere is changed, extreme weather events ...

A gigantic, steaming-hot mound of compost is not the first place most people would search for a solution to climate change, but the hour is getting very late. "The world experienced unprecedented high-impact climate extremes during the 2001-2010 ...

This story first appeared in Slate and is reproduced here as part of the Climate Desk collaboration. A gigantic, steaming-hot mound of compost is not the first place most people would search for a solution to climate change, but the hour ...

Climate scientists may have to rethink some of their old assumptions about carbon. US and European researchers have just established that black carbon, soot and biochar -- the burnt remains from countless forest fires -- doesn't stay in the soil ...

It was only a matter of time before somebody broke the fragile social and political consensus surrounding geoengineering, and had a first crack at "experiment Earth". The news that American businessman Russ George has dumped 100 tonnes ...

Adding a charred biomass material called biochar to glacial soils can help reduce emissions of the greenhouse gases carbon dioxide and nitrous oxide, according to U.S. Department of Agriculture (USDA) scientists. Studies by scientists ...

Soils store three times as much carbon as plants and the atmosphere. Soil organic matter such as humus plays a key role in the global carbon cycle as it stores huge amounts of carbon and thus counters global warming. Consequently, the Kyoto ...

Imagine a toilet that takes human waste and converts it into minerals for fertiliser and clean water, while harvesting energy in the process. The toilet doesn't use water, doesn't need expensive infrastructure of a sewerage system, ...

Techno-fix ideas include artificial trees and firing silver iodide into clouds to produce rain.The alert on the Climate Ark website in January 2009 was marked urgent: "Take action: A rogue science ship is poised to carry out risky ...

New Zealand study shows biochar to decrease nitrous oxide emissions Nitrous oxide is a potent greenhouse gas and a precursor to compounds that contribute to the destruction of the ozone. Intensively managed, grazed pastures are ...

Nitrous oxide is a potent greenhouse gas and a precursor to compounds that contribute to the destruction of the ozone. Intensively managed, grazed pastures are responsible for an increase in nitrous oxide emissions from grazing animals' ...

It seems modest, as power plants go -- a 29-megawatt facility, situated just north of the Vermont-Massachusetts line, that will burn woody biomass to generate enough power for 25,000 to 30,000 homes. But like many proposed plants in the recently ...

Sadly, as the threat of climate change worsens, U.S. lawmakers move further away from practical solutions. Last week, NASA reported that 2010 was the second hottest year on record, capping the warmest decade in modern times. Climate ...

Gore to address Aspen Forests at Risk event, Glenwood Springs Post Independent
Gore to address Aspen Forests at Risk event Symposium to focus on climate change and the future of western forests Former Vice President and Nobel laureate Al Gore will join forest scientists and policy makers at a February ...

It has an appealing symmetry to it: If we got ourselves into this climate mess by digging up and burning coal, maybe we can fix it by creating some more coal and putting it back into the ground. That very idea, involving the ...

Not long ago, it seemed that big money and boundless optimism were all that were needed to solve some of the biggest environmental problems facing the planet. An initiative from Richard Branson, the shaggy-haired billionaire owner of ...

Win-win solutions can be hard to come by. But if Cornell University soil scientist Johannes Lehmann is right, there may be a way to lower our emission of heat-trapping greenhouse gases, save millions of people's lives, and significantly boost the ...

Simmered out of eucalyptus, charcoal is being hoed into the degraded soils of former forests in western Kenya. Roasted out of chicken manure, it is spurring the growth of malting barley in Australia. And in Iowa, researchers are plowing charcoal ...

Biochar--the agricultural application of charcoal produced from burning biomass--may be one of this century's most important social and environmental revolutions. This seemingly humble practice--a technology that goes back thousands of years--has ...

The idea of burying charcoal produced from microwaved wood to tackle global warming is still beset with scientific uncertainties, says the UK government's first report on "biochar". The warning comes as a separate US study published this ...

The release of more than 370 billion tons of carbon (GtC) from buried early biospheres, adding more than one half of the original carbon inventory of the atmosphere (~590 GtC), as well as the depletion of vegetation, have triggered a fundamental ...
