Does the Earth Need Chemo?
In a recent conversation, a Berkeley climate scientist compared geoengineering to chemo: you may find out it’s your only choice, but it would be better not to get cancer in the first place. Likewise, we might need geoengineering, but it would be better if we didn’t pump the atmosphere full of carbon. Nevertheless, it’s important …

CONTINUE READINGChina’s Growth in Energy Usage Truly Alarming
Cara blogged earlier this week about the fact that U.S. emissions were down “a whopping 7 % in 2009.” Just when you might have been thinking that we are headed in the right direction on the climate change front, today’s New York Times has a distressing story about Chinese emissions. The take home point: Coal-fired electricity …

CONTINUE READINGShould We Run Some Controlled Climate Change Experiments?
Controlled experiments in general are the best way of doing science, but we haven’t been able to take advantage of that in science research. Considering the importance of the climate change issue, it might be worth taking a serious look at this possibility, even if it does seem a little outside the box.

By Jed Ela, UCLA Law delegation — part of a series of posts on COP 15 from Copenhagen: Deep in the bowels of COP15, in a temporary, metal-walled conference room nestled like a shipping container into a vast temporary hangar housing national delegation offices, a presenter from Google is apologizing. The Google team has lured …

CONTINUE READINGSuperFreakonomics and Climate Change
If you haven’t been following the controversy that has erupted with the publication of SuperFreakonomics: Global Cooling, Patriotic Prostitutes and Why Suicide Bombers Should Buy Life Insurance, you should be. In SuperFreakonomics — the sequel to Steven Levitt and Stephen Duber’s wildly popular Freakonomics — the authors take on climate change. Their arguments are somewhat …

CONTINUE READINGThe Royal Society’s geoengineering report
We had a flurry of posts on geoengineering a while back (see here, here, here, and here). If you want to learn more about geoengineering, a great resource is this report, just issued by the Royal Society. It clearly explains the background, the approaches being proposed (which divide broadly into technologies for removing greenhouse gases …

CONTINUE READINGStill more on climate engineering
There’s a lot of enthusiasm in some circles for “geo-engineering” as a response to anthropogenic climate change, and a lot of skepticism about it in others. The appeal is obvious — controlling greenhouse gas emissions looks difficult, since our economies and many of our daily habits (at least in the developed nations, which are providing …

CONTINUE READINGMore on reengineering – what about the oceans?
Regarding Dan’s post on reengineering the planet, one more shortcoming of the commonly discussed geoengineering solutions (even assuming they work exactly as designed and have none of the unintended consequences Dan, and others, fear) is that they are far from complete, leaving out entirely any remedy for ocean acidification, the “other” greenhouse gas problem. More info on …

CONTINUE READINGManaging Technology and Dangerous Climate Change
The risk of catastrophic climate change puts uncertainties associated with innovative energy and carbon sequestration technology in a new light, and the short time for effective greenhouse gas emission reduction challenges public decision-making processes. Interest in this topic has been spurred by the drive to bring new energy and green house gas emission reduction technologies …

CONTINUE READINGIs Geoengineering Inevitable?
As I write, talk, teach and think about climate change seemingly non-stop these days, I frequently come back to the pessimistic conclusion that we cannot solve the climate problem through mitigation of greenhouse gas emissions. I have this pessimistic thought while believing wholeheartedly that we must enact aggressive policies to cut emissions dramatically. My pessimism stems …
