> Plant a ton of trees and the CO2 problem solves by itself. Citation? Obviously we're emitting CO2 at some rate E and a ton of trees will sequester that CO2 at another rate S. But it's not clear that you've measured and compared those two numbers. |

This has to do with a study about the measurement of the impact deforestation of tropical forests has on global warming.
> How big is three billion tons?
Three billion tons of anything is a lot, but it’s hard to grasp just how much — particularly when it’s tons of CO2, which we don’t have any everyday experience in weighing. One way to look at it is that the average U.S. car emits about 5 tons of CO2 a year from the tailpipe, so three billion tons is the equivalent of 600 million cars — about twice as many as there are in the whole United States. Another way of expressing it is that this is the equivalent of about 13 million railcars full of coal, which would stretch about 125,000 miles (half the distance to the moon). It's also equal to the total emissions from Western Europe, including Austria, the Czech Republic, Slovenia, all the Scandinavian countries, and Finland.
