When I first saw Desmogblog publicize their cost figure of $10 per person, I thought they had made a mistake and posted to that effect. Then they repeated that figure three or four times and I realized they were just doing whatever it is P.R. people do.
Here's an example of someone who picked up on the meme:
"Kevin Grandia of the global warming denialist-busting website, DeSmogBlog, has done the calculations - it only takes $10 per person per year to save the planet.
The UN's Intergovernmental Panel on Climate Change concluded that it would cost .12% of the world's domestic product to substantially reduce our collective greenhouse gas emissions.
- GDP of the world economy: US$60 trillion
- .12% of $60 trillion: $70 billion
- Total population of the earth: 6.5 billion
- Cost per person to significantly reduce heat-trapping gas worldwide: $10 a year
- Cost of saving the planet from droughts, famine, mass flooding, species extinction and rising sea levels: priceless.
That's from a site called Clipmarks, now I grant you it's not the Wall Street Journal, Times of London, New York Times, LA Times or the Financial Times but the meme did get some traction.
Here's the post I put up in response: "The Innumerate Leading the Illiterate"
