What’s New on the Seven Seas?

The scientific journal Nature reports on two recent research findings.  One is bad news.  I think the other is good news, but not everyone will agree. The first report (the bad news) is a reminder that ecological harm is a cumulative process: The [new] study suggests that the cold weather was the first of three …

Geoengineering and Conflicts of Interest?

Is it unethical for scientists studying techniques to geoengineer the earth’s climate to advocate for additional government funding to expand the study of the science and geopolitics of the topic?  That’s the conclusion of a recent Guardian article that criticizes Harvard’s David Keith and the Carnegie Institute’s Ken Caldeira for a) receiving outside money to …

Tough Political Choices On Climate Are Hardly Unique to U.S: The Case of Germany and Nuclear Power

German Chancellor Angela Merkel made headlines this week when she announced that the country would phase out its nuclear power plants by 2022.  The Fukishima nuclear crisis in Japan led Germany to review its reliance on nuclear power and the result of that review was Merkel’s decision to shut down the country’s existing plants. Here’s …

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 …

China’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 …

Should 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.

Overall impressions of COP/MOP: World Governance for the Climate-as-Artifact

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 …

The 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 …

Still 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 …
