One of the world s most complex experiments on the impact ofrising levels of carbon dioxide is taking shape in easternAustralia, where giant steel frames nine stories high have beenbuilt on native woodland. The project near Sydney will mimicfuture climatic conditions by simulating higher atmosphericconcentrations of carbon dioxide. Measuring carbon dioxide Carbon dioxide is pumped into an environmental time machine onthe outskirts of Sydney, aiming to predict how vegetation willreact to future climate change. The experiment features giant cylindrical steel frames 28 meterstall that rise above native woodland, called bushland. Theywill simulate elevated levels of CO2 that the planet couldexperience in the next half century. Professor David Ellsworth from the University of Western Sydney isin charge of this unique project. We have six of these arrays ofpipes up in the woodland designed to emit carbon dioxide in acomputer-controlled system so we can study how this ecosystemresponds a rising atmospheric carbon dioxide concentration, hesaid. It has taken researchers a year to build this industrial-lookingecological experiment, which will last for a decade. The university says it is the world s biggest outdoor carbondioxide trial, and the only one to use mature woodland. My name is Steven Wohl from the University of Western Sydney. I am the senior engineering officer for the EucFace site. Wherewe are going up now is a 22-meter tall modular scaffolding placedin the center of the ring," he explained. "It allows us to placeinstrumentation at different heights in the canopy and also givesthe researchers a unique perspective of the canopy. Long-term project , research Professor Ellsworth says the research, which will last for adecade, will give policy makers more information about how to planfor future climate change. We re hoping to find out how thisecosystem actually responds to carbon dioxide concentration of thefuture, and whether it will actually store more carbon or not. That s really important from the standpoint of native bush inAustralia which occupies a very large part of our land mass, henoted. Australia s large tracts of undeveloped land, known as bush, are akey part of plans to store carbon emissions. How much carbon theecosystem can absorb is a key question for the country s future. If native bush is not able to do more than it currently does atthe present day, then we need to know that pretty urgently. Ithink, said Ellsworth. Ian Anderson is a director of research at the University of WesternSydney, which has a range of studies looking at shifting levels ofcarbon dioxide. Most of our experiments are aimed at looking at in the order of30-50 years ahead based on predictions, so our CO2 concentrationsand our temperature treatments are based around looking ahead tothat sort of timeframe. We also have the experimentalfacilities to actually look back in time," said Anderson. "So wecan actually take CO2 out of the atmospheres in some of ourcontrolled environment rooms and look at how those plants would veresponded back in time, I guess to build up a bit of a picture ofwhere they ve been, where we are now and where we are going to goto in the future. Funded by taxpayers, the government says these experiments willtransform climate change research in Australia, which emits moregreenhouse gas pollution per person than anywhere else in thedeveloped world.
