Time to lift the geoengineering taboo
Hot on the heels of the Royal Society's Geoengineering the Climate report, September's Physics World contains feature comment from UK experts stressing the need to start taking geoengineering - deliberate interventions in the climate system to counteract man-made global warming - more seriously. view more (2009-09-01)
Geoengineering could slow down the global water cycle
As fossil fuel emissions continue to climb, reducing the amount of sunlight hitting the Earth would definitely have a cooling effect on surface temperatures. view more (2008-05-28)
Geoengineering climate requires more research, cautious consideration and appropriate restrictions
Geoengineering - deliberately manipulating physical, chemical, or biological aspects of the Earth system to confront climate change - could contribute to a comprehensive risk management strategy to slow climate change but could also create considerable new risks. view more (2009-07-22)
Carnegie Institution
The future of the Earth could rest on potentially dangerous and unproven geoengineering technologies unless emissions of carbon dioxide can be greatly reduced, a new study has found. view more (2009-09-01)
Global sunscreen won't save corals
Emergency plans to counteract global warming by artificially shading the Earth from incoming sunlight might lower the planet's temperature a few degrees, but such "geoengineering" solutions would do little to stop the acidification of the world oceans that threatens coral reefs and other marine life. view more (2009-06-17)
World needs climate emergency backup plan, says expert
In submitted testimony to the British Parliament, climate scientist Ken Caldeira of the Carnegie Institution said that while steep cuts in carbon emissions are essential to stabilizing global climate, there also needs to be a backup plan. view more (2008-11-10)
Stratospheric injections could help cool Earth, computer model shows
A two-pronged approach to stabilizing climate, with cuts in greenhouse gas emissions as well as injections of climate-cooling sulfates, could prove more effective than either approach used separately. view more (2006-09-15)
No quick or easy technological fix for climate change, researchers say
Global warming, some have argued, can be reversed with a large-scale "geoengineering" fix, such as having a giant blimp spray liquefied sulfur dioxide in the stratosphere or building tens of millions of chemical filter systems in the atmosphere to filter out carbon dioxide. view more (2008-12-18)
Atmospheric 'Sunshade' Could Reduce Solar Power Generation
The concept of delaying global warming by adding particles into the upper atmosphere to cool the climate could unintentionally reduce peak electricity generated by large solar power plants by as much as one-fifth, according to a new NOAA study. The findings appear in this week's issue of Environmental Science and Technology. view more (2009-03-12)
Carbon dioxide already in danger zone, warns study
A group of 10 prominent scientists says that the level of globe-warming carbon dioxide in the air has probably already reached a point where world climate will change disastrously unless the level can be reduced in coming decades. view more (2008-11-19)
