Oh the irony.
[and they don't even address the problem that most trees don't pull much CO2 out of the air, they put most of it back, and ultimately they release all the carbon back into the atmosphere, much of it as methane and other more powerful GHGs. I wonder if they're deciduous trees, which basically convert a good chunk of CO2 into methane every year.
Oh, for those who don't want to do the reading, the paper says due to albedo and water transport/feedback effects, unless they covering very dark soil AND in the tropics, trees cause warming.]
