Picturing a ton of CO2

Tons of CO2 pollution. We are always hearing about how many tons of CO2 pollution we emit. The average American car emits about seven tons of CO2 in a year; the average American family, about 24 tons; the United States as a whole, over seven billion tons; and worldwide, almost 30 billion tons. 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?

And for all these reasons, he says, the Kyoto protocol was correctly rejected by the U.S.

What's "cap-and-trade"?

In my post last Friday, I mentioned “cap-and-trade” as a good strategy to control greenhouse gas emissions. If you’d like to learn more about cap-and-trade, take a look at a post I wrote for the Gristmill Blog.

Global Warming Solutions that Work

There was an interesting Op-Ed in the Washington Post Wednesday titled “Global Warming and Hot Air,” by Robert Samuelson.

Samuelson is a smart guy who gets the science and asks the right questions on economics. And we do agree on the need for new technologies and clean energy options. The question is how to accomplish this.
