Risky Business

From last night’s NewsHour on PBS, Silicon Valley venture capitalist Vinod Khosla talked with economics reporter Paul Solman about global warming and the choice of doing nothing:

Khosla: I won’t contend that I can prove with 100% certainty, but 98% of the scientists, maybe more, believe that we have a serious climate problem. … You can’t prove that your house is gonna burn down.

Solman: No, I don’t think my house is gonna burn down.

Khosla: No, you don’t. But you still pay — every year, year after year — your insurance premiums, to make sure, just in case. Are we willing to take that kind of risk at the planetary level, for earth, and not buy any insurance?
