Globally, tropical trees in undisturbed forest are absorbing nearly a fifth of the CO2 released by burning fossil fuels.
The researchers show that remaining tropical forests remove a massive 4.8 billion tonnes of CO2 emissions from the atmosphere each year. This includes a previously unknown carbon sink in Africa, mopping up 1.2 billion tonnes of CO2 each year.
"We are receiving a free subsidy from nature," says Dr Simon Lewis, a Royal Society research fellow at the University of Leeds, and the lead author of the paper. "Tropical forest trees are absorbing about 18% of the CO2 added to the atmosphere each year from burning fossil fuels, substantially buffering the rate of climate change."
The reason why the trees are getting bigger and mopping up carbon is unclear. A leading suspect is the extra CO2 in the atmosphere itself, which may be acting like a fertiliser.
The Intergovernmental Panel on Climate Change reports that globally human activity emits 32 billion tonnes of CO2 each year, but only 15 billion tonnes actually stays in the atmosphere adding to climate change. The new research shows exactly where some of the 'missing' 17 billion tonnes per year is going.
"It's well known that about half of the 'missing' carbon is being dissolved in to the oceans, and that the other half is going somewhere on land in vegetation and soils, but we were not sure precisely where. According to our study about half the total carbon 'land sink' is in tropical forest trees," explains Dr Lewis.

Liberals think it’s much better to scare us into destroying our industry and economy.
Hence: The Global War on Carbon, or GWOC.
Be afraid; be a fraydee cat.
Maybe these guys finally remembered how photosynthesis works.
I learned this in an earth science class 50 years ago.
This a** exhaled CO2. If he just held his breath, we wouldn’t have a problem. //sarc//
Once again atmospheric scientists discover what should be obvious to anyone seriously paying attention. Not that this information is surprising to the scientists themselves, but somehow the “environmentalists” are shocked that plants absorb CO2 since most of them don’t understand even basic biology.
I nominate this statement for the most idiotic statement of the year award. Free subsidy from nature? How do we pay nature when its not free? Throw virgins over a cliff?
Does this man realize his very birth is a "free subsidy from nature". Does he realize where this nature comes from and that he owes his life to and is a creation of God?
Okay, here is the runner up. That is what trees do. They get bigger and absorb carbon dioxide.
Is it any wonder so many folks cannot question global warming theories?
If it wasn’t free, they could somehow tax it, that evil tax evading nature subsidy.
I want a rebate on my carbon credits.
i will only say this once, THERE IS NO SUCH A THING AS FOSSIL FUELS..... and in order to prove this statement, bury a dead animal in the yard and dig it up a year later....do you find any oil?
