Exxon Changes its Tune

What a difference nine years makes!

For more than a decade, Exxon has been a major player in a campaign to spread doubt about global warming.

The stated goal of the plan, whose authors include Randy Randol of Exxon Corp, Sharon Kneiss of Chevron Corp, and Joseph Walker of the American Petroleum Institute, was to change the American public’s view that global warming was a threat so that policies to curb greenhouse gas emissions could be stopped. The memo laid out a wide range of strategies and tactics to achieve this goal, budgeting nearly $6 million plus the cost of advertising.

The Virgin Earth Challenge (see last week’s post) offers $25 million to whoever can economically remove one billion tons of CO2 from the atmosphere each year.

But what is a ton of CO2?

Vacuum Up Greenhouse Gases?

Everybody’s always talking about reducing greenhouse gas emissions. What you don’t hear so often is a suggestion to clean up what’s already there. How would you do that? Good question!
