Published today on Independent Science News: Climate Technofix: Weaving Carbon into Gold and Other Myths of “negative emissions” by Rachel Smolker, Co-Director of Biofuelwatch.
Synopsis: IPCC models for achieving even potentially safe levels of climate change (i.e. 430-480ppm CO2 and 2ºC of warming) are not as plausible as is widely assumed. Buried in the small print of those models is an expectation that viable carbon capture technologies will create “negative emissions”. Yet no such technology currently exists. The only one mentioned by the IPCC as “near term available” is Bio-Energy with Carbon Capture and Sequestration (BECCS). Smolker’s excellent article describes the short, costly and painful history of BECCS (and carbon capture as a whole) and why the 2ºC roadmap needs a new route if it is to avert disastrous climate change.
