Global Warming May Necessitate Carbon Dioxide Scrubbers
Advocates say that while large-scale air capture projects might be a long time away, their economics aren’t as bad as everyone assumes. Roger Pielke Jr., a political scientist who studies energy and climate policy at the University of Colorado, conducted a recent study that found that stabilizing greenhouse gas concentrations with air capture using today’s technologies could about equal the costs projected by the IPCC of other ways to deal with warming.
We Must Reframe the Climate Change Challenge
Scientists like Dr. Kevin Anderson have lost patience with carefully constructed messages about dangerous climate change being lost in the political noise. We are now prepared to stand up and say enough is enough.
Global Warming Solutions for Governments
To stop Global Warming, we must close down all coal-fired power plants, end all fossil fuel subsidies and end all corporate campaign financing.
Climate Change Challenge: Is Clean Coal a Solution?
CCS is a very expensive distraction, designed to make coal look good, but in reality taking scarce taxpayers’ dollars away from solutions that can make a real difference. Governments should place an immediate ban on new non-CCS coal-fired projects, as New Zealand and British Columbia have done, and set a date by which power companies will be required to stop buying coal-fired power, as California has done.
Article on carbon capture and storage misguided
CCS should never be considered a bandaid or quick fix. It should only be attempted in conjunction with a global effort to reduce GHG emissions to zero. It will be difficult enough to sequester what we already have. If we can’t bring atmospheric carbon dioxide down to what is believed to be the safe level of 350 parts per million or less, we won’t have a planet we can live on.
Controlling Climate Change with Geo-Engineering
“Geo-engineering is not a solution,” says Prof Launder, “but it could give the world a chance to come to its senses. In 50 years we’ll have carbon-free energy schemes in place, but we need a solution that can be put into place shortly, and will gain us breathing space.”
Hansen et al: We must phase-out coal emissions by 2030 and stabilize at or below 350 ppm

“Geo-Engineering” Schemes Investigated by Royal Society
Climate damage science studied By Pallab Ghosh Science correspondent, BBC News http://news.bbc.co.uk/2/hi/science/nature/7698805.stm The UK’s Royal Society is to investigate whether ambitious engineering schemes could reduce the impact of global warming. Several “geo-engineering” schemes have been proposed including putting mirrors into space and iron filings in oceans. The society says these must be properly [...]
Water-Vapor Feedback a Critical Threat to Our Planet
Editor’s note: The time for a negative feedback is certainly now. How can we make this happen? Shouldn’t we also consider the artificial removal of carbon as well as slashing carbon emissions? Study: Water-vapor feedback is “strong and positive,” so we face “warming of several degrees Celsius” A new study in Geophysical Research Letters (subs. [...]
