In real estate it's location, etc. In global warming it may well be about the timing, the speed of change reflected in this interview. Sure, the earth's always going through heating and cooling cycles, but as this diver and conservationist argues, has the planet ever warmed this rapidly? Essentially the global warming has happened in just the 200 years since the Industrial Revolution kicked off our fossil fuel orgy. See my blog on CO2 concentrations.The interview with the diver began as a piece about the movie, "The Cove," and dolphin slaughter in Japan. But you can't really notice much about the environment these days without global warming heating up the conversation. STANDARD BOILER PLATE This verbiage will now be attached to any blog I do about global warming. It’s amazing to me that somebody who can apparently read and then post comments still wonders in public why global warming matters on a technology web site. But I am naive, always assuming everybody’s paying attention. It’s because of money. If global warming has enough acceptance among corporations, the public and even pols, there will be more money spent on green tech, wisely or unwisely. If oil prices stay low and most people don’t care a fig about global warming, green tech will have a difficult time succeeding, regardless of its merits. Not every good idea succeeds. VCs usually invest where they think there’s best chance for a good return. In greentech as in any tech the winners will often be determined by luck, brilliance, timing, happenstance and even marketing. Behind it all will be the money and behind that: whether the evidence for global warming and curtailing pollution drive action or is written off as claptrap.
