UK scientists to track effects of increasing CO2 levels through 'sci-fi' forest!

Researchers believe that as levels of CO2 increase the trees will fix more of carbon into their trunks, roots and organic matter in the earth.

New Delhi: With an aim to figure out how forests will respond to the levels of atmospheric carbon dioxide expected by the middle of the 21st century, scientists in the UK have developed a 'sci-fi' outdoor laboratory in a Staffordshire forest.

With the forest surrounded by a three-metre anti-climb fence and silvery tubes snaking along the forest floor, the industrial-scale experiment encircles trees with 25 metre masts gushing high levels of carbon dioxide (CO2).

Researchers believe that as levels of CO2 increase the trees will fix more of carbon into their trunks, roots and organic matter in the earth.

"We are confident that trees will continue to take in more CO2, though we are quite sure that there will be other things that will start to limit that," said Rob Mackenzie, from Birmingham University.

"Rising temperatures will also change the ability of plants to absorb CO2 – they are adapted to current temperatures," Mackenzie told the 'BBC News'.

Humans and forests currently participate in a mutually beneficial exchange in which trees are fed by increasing CO2, and the trees in turn lock up carbon that would otherwise remain in the atmosphere, heating the planet.

Trees are estimated to be storing between a quarter and a third of the carbon produced by burning fossil fuels, and the earth is becoming greener as a result.

One of the great imponderables in climate science is how long forests will continue to buffer climate change as CO2 levels continue to increase.
