A proposed method to reduce future global warming could alter precipitation patterns throughout the world, according to a study led by scientists from the National Center for Atmospheric Research.
Known as geoengineering
, the approach ...
Last year the Haida, an indigenous group in Canada, set out to increase their salmon stocks and save the planet. Helped by American businessman Russ George, a group of villagers dumped 100 metric tons (110.23 tons) of iron dust from a boat into ...
Installing a giant mirror in space to block sunlight, dispersing mass quantities of minerals into the oceans to suck carbon dioxide from the air and infusing the Earth’s upper atmosphere with sun-reflecting chemicals might sound like the stuff of ...
Late in the afternoon on April 2, 1991, Mt. Pinatubo, a volcano on the Philippine island of Luzon, began to rumble with a series of the powerful steam explosions that typically precede an eruption. Pinatubo had been dormant for more than four ...
to combat global warming by injecting sulfate particles into the atmosphere can't fully offset human-caused climate
change, U.S. scientists say.
Researchers at the University of Washington say that suggested method would ...

Scientists call it "geoengineering," but in plain speak, it means things like this: blasting tons of sulfate particles into the sky to reflect sunlight away from Earth; filling the ocean with iron filings to grow plankton that will suck up ...
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 ...
A Calgary researcher has developed two new approaches to the controversial science of geoengineering
-- a tool its proponents say could one day prevent global warming, but which some environmental groups dismiss as a coverup of political ...
The idea goes something like this: nations would send megatons of light-scattering aerosol particles into the globe's upper atmosphere, significantly reducing sunlight reaching the earth and thereby immediately cooling the Earth. While the idea ...
Frank Raes is head of the climate
change unit at the Joint Research Centre's (JRC) Institute for Environment and Sustainability.
He was speaking to Susanna Ala-Kurikka.

Emissions of carbon dioxide are rising even faster than was expected, and if they continue to do so we are on track for global temperatures which are likely to be 4C higher, or even more, by 2100, with disastrous consequences. With no action ...
A plan to inject sulphate aerosols into the stratosphere, as a quick fix to
counteract global warming, may drastically increase Arctic ozone depletion and
slow the recovery of the Antarctic ozone hole, researchers warn.
