Shocking news! Trees may not be the answer

I was reading about Albedo in the Global Warming Bible.

The balance between energy absorbed by the earth and energy reflected back into space is fundamental in determining how warm or cool the planet becomes.

It seems that the albedos of forests lie in the range 0.07–0.15, while deserts have an albedo of around 0.3.
Does this mean that Trees actually contribute to Global warming twice as much as dirt?
So how much solar radiation is being absorbed by the Hollywood forest that Al Gore & friends have planted in the past year?
How much would have otherwise been harmlessly reflected back into space by the cold... er I mean Dangerously warming hard ground?
