With the IPCC suggesting strong negative emissions, or strong removal of atmospheric carbon, as the only way to avoid dangerous climate change (see here), we have no choice. We must remove already emitted carbon dioxide from our skies. The U.S. Geologic Survey (USGS) is looking at one of the better ways of doing this using…
First Published on Truthout, August 27, 2014 (link) The fundamental climate change policy question today is not how much we should reduce carbon dioxide emissions by when, but what will currently proposed carbon dioxide emissions reductions do to our climate in the near-term? In addition, what are the ramifications of short-lived climate pollutants that are…
Direct atmospheric removal (air capture) should not be confused with geoengineering. These air capture techniques, old and new, remove CO2 from the atmosphere just like we remove other pollutants from say, water in our wastewater facilities, or simply sweeping up dirt from the kitchen floor. Existing technologies extract CO2 from the air with chemicals such…
How do we curb emissions with the way our society has evolved? Really. I mean serious curbing; enough to prevent dangerous climate change? When considering the answer, dangerous climate change must be clearly defined. So, what exactly is dangerous climate change? Read More — First published on the Rag Blog
A study by a team from Cornell says the IPCC is conservative. Press Release, Cornell: World policymakers have underestimated climate change impacts, says Cornell expert: Carbon must be scrubbed from atmosphere. Charles H. Greene, Cornell professor of Earth and atmospheric science, has published in the peer-reviewed journal Oceanography (March 2010). Greene is joined on the…
