Nature’s Remedy: Restoring the Forests can fight Global Warming—but only if left to Free Markets not Regulators,TIME magazine, December

I found this quote which surprised me positively:

In addition, we can reduce and offset up to 20% of our emmissions by conserving and restoring the world’s forests. Forests not only store twice as much carbon as there is in the atmosphere, but constantly reabsorb it through photosynthesis. Nature’s carbon-storage technology is extraordinarily efficient and can mitigate climate change better over the next 50 years than, say, the enlightened efforts of the energy or transportation sectors.

Forests not only store twice as much carbon as there is in the atmosphere,

That means that ith 50% more forest all CO2 will be absorbed???????? or that it is a big living thing, breezing in and out daily???
