Your link claims the 1 trillion tree estimate is wrong. But it doesn't propose an alternate number. Here's a back of the envelope calculation: a tree absorbs about 48 pounds of CO2/year [1], which is 22kg. So, one trillion trees absorb 22 GT/year. The world puts out 36 GT/year (or about 50 GT of CO2-equivalent if you include methane and other greenhouse gases). One trillion might not be enough, but 2 could do the trick.
