After enduring nearly a decade on the political margins, climate-change policy has returned to mainstream politics in the United States rapidly with the election of President Barack Obama. While advocates of pro-active federal climate-change policy undoubtedly helped galvanize this dramatic reversal, they are unlikely to sustain popular political support without adjusting the strategies they...

A small group of highly-respected climate-change and Earth systems scientists testified before the U.S. House of Representatives today in a hearing titled the hearing titled “Geoengineering: Assessing the Implications of Large-Scale Climate Intervention,” which explored the current lack of geoengineering research and the need for ramped up research efforts in this area.
“Geoengineering” is a...

The fate of the planet may depend on high-risk and unproven geoengineering technologies unless emissions of carbon dioxide can be greatly reduced, a new study by the U.K.’s Royal Society has found.
Unless greenhouse gas emissions are reduced significantly, geoengineering will likely be necessary to cool the planet. The Royal Society identified major uncertainties regarding the effectiveness, costs, and environmental impacts of...

The evidence linking human-based greenhouse-gas emissions and the increase in global average temperatures over the last half century has been established beyond a reasonable doubt. Current and future GHG emissions are likely to exacerbate the severity of climate change and amplify the problems it creates for most nations.
The American Meteorological Society has described the menu of choices humanity has for purposes of formulating a response to climate change...

The future of the Earth could rest on potentially dangerous and unproven geoengineering technologies unless emissions of carbon dioxide can be greatly reduced, the latest Royal Society report has found.
Geoengineering the climate: Science, governance and uncertainty found that unless future efforts to reduce greenhouse gas emissions are much more successful than they have been...

Geoengineering and the carbon dioxide problem
Cesare Marchetti
March 1, 1977
The problem of carbon dioxide control in the atmosphere is tackled by proposing a kind of fuel cycle for fossil fuels where carbon dioxide is partially or totally collected at certain transformation points and properly disposed of. Carbon dioxide is disposed of by injection into suitable...

Early on the morning of Feb. 24, 2009, the National Aeronautics and Space Administration launched what was likely one of the most politically loaded satellites ever sent into space—the Orbiting Carbon Observatory. The OCO, perhaps the most powerful remote-monitoring system created for tracking changes in the chemical composition of Earth’s atmosphere, cost $387 million...

TheU.S. Environmental Protection Agency wants to regulate sources of GHG emissions under the Clean Air Act’s Prevention of Significant Deterioration (PSD) and Title V programs using a size threshold 100 times higher than that included in the Clean Air Act, according to a proposal the EPA sent to the White House Office of Management and Budget (OMB) last week.
Under the Clean...
