Can geoengineering put the freeze on global warming?

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 ...

As climate talks drag on, more ponder techno-fixes

(AP) -- Like the warming atmosphere above, a once-taboo idea hangs over the slow, frustrating U.N. talks to curb climate change: the idea to tinker with the atmosphere or the planet itself, pollute the skies to ward off ...

Climate change: Can geoengineering satisfy everyone?

Reflecting sunlight from the Earth by geoengineering would undoubtedly cool the climate, but would different countries agree on how much to reflect? Research by climate scientists at the University of Bristol shows that the ...

Can we predict when and where rock will fall?

(PhysOrg.com) -- Falling rock shatters the tranquillity of Yosemite National Park about every 10 days, and occasionally leads to fatalities. What forces trigger a rockfall? Are there precursor signals that one is imminent? ...

Bright water proposal to cut global warming

(PhysOrg.com) -- A Harvard physicist has proposed the Earth could be cooled by pumping vast numbers of tiny bubbles into the sea to lower ocean temperatures and increase the water’s reflectivity. The same strategy could ...

Geoengineering takes a ride in the shipping lanes

Ships blowing off steam are helping researchers understand how manmade particles might be useful against global warming. New results from modeling clouds like those seen in shipping lanes reveal the complex interplay between ...
