The Buzz: Geo-Engineering Potential Examined

The potential for various geo-engineering proposals to offset the effects of climate change is often not factored in to near- and long-term climate scenarios. In a study conducted by NOAA, released this week, the authors predicted "irreversible changes," but noted, "we do not consider geo-engineering measures that might be able to remove gases already in the atmosphere or to introduce active cooling to counteract warming." Days later, one of the first in-depth analyses of these measures was published, considering both the feasibility and potential payoffs of several geo-engineering schemes.

So a fair degree of warming is inevitable, eh? That's the conclusion of a PNAS paper making the rounds this week. (I wrote about it yesterday.) But just how "irreversible" are the coming changes? As Arthur C. Clarke said, "When he states that something is impossible, he is very probably wrong." The…
Can't let this week slip any further past without drawing your attention to a new paper on "Irreversible climate change because of carbon dioxide emissions," which has just been published in the Proceedings of the National Academy of Sciences. (It can be found here), and I have a copy and will…
The Economist has an interesting article on ideas for cooling the planet directly -- in manners other than CO2 emissions reductions -- and how they are being received: This gloomy outlook has encouraged new interest in a technological fix. A scientific journal, Climatic Change, published a series…
Last week, John Holdren appeared for a 45 minute interview on NPR Science Friday with host Ira Flatow. Below the fold, I have pasted excerpts of his comments relative to climate change policy options as well as investment in nuclear energy. In the interview, Holdren also had the chance to elaborate…
