Increased Interest in ‘Artificial Trees’ for Removal of Carbon from Atmosphere
Many climate scientists calculate that the world has only a few decades to reduce emissions before there is so much carbon dioxide in the atmosphere that a dangerous rise in global temperature is inevitable. The authors of this report say that geo-engineering of the type they propose should be used on a short-term basis to buy the world time, but in the long term it is vital to reduce emissions.
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.
