Geoengineering approaches to reduce climate change unlikely to succeed

ScienceDaily: Reducing the amount of sunlight reaching the planet's surface by geoengineering may not undo climate change after all. Two German researchers used a simple energy balance analysis to explain how Earth's water cycle responds differently to heating by sunlight than it does to warming due to a stronger atmospheric greenhouse effect. Further, they show that this difference implies that reflecting sunlight to reduce temperatures may have unwanted effects on Earth's rainfall patterns. The results are...

Once we start geoengineering, it may be hard to stop

Grist: Despite the antics of technofixers, policy wonks, and mad billionaires everywhere, geoengineering persists as an appealing-if-wacky solution to all our climate ills. The basic logic is seductive: If weve messed up the climate by pumping bad stuff into the atmosphere, maybe we can undo some damage by pumping some other stuff up there, too. Of course, a minefield of potential blunders awaits the intrepid geoengineer, including wreaking havoc on rainfall or depleting polar ozone. And then there is...
Study finds geoengineering research free for all

SciDevNet: The 'plan B' of using geoengineering to rescue humanity from the impact of climate change exists in a 'vacuum' of international regulations, according to a recent review. Proposals to counteract the effects of global warming by engineering the planet, with methods such as spraying chemicals into the atmosphere to block solar radiation, are largely theoretical and lacking in research. But they prompt debate, with some scientists rejecting particular geoengineering proposals altogether, and others...

Geoengineering the Climate Could Reduce Much Needed Rain, Study Suggests

Nature World: 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 could cause a 4.5 percent decrease in the global average precipitation, the study found. "It's very much a pick-your-poison type of problem," co-author John Fasullo said in a statement. "If you don't like warming, you can reduce the amount of sunlight reaching...

Terraforming Earth: Geoengineering megaplan starts now

New Scientist: THIS is how we will hold off disaster. To help us avoid dangerous climate change, we will need to create the largest industry in history: to suck greenhouse gases out of the air on a giant scale. For the first time, we can sketch out this future industry - known as geoengineering - and identify where it would operate. The Intergovernmental Panel on Climate Change now considers geoengineering to be respectable. The reason is simple. Unless our greenhouse gas emissions start falling soon, Earth...
