multimillionaires bushes study subjects with high levels of precipitation patterns and impaired CO2
an Australian university has embarked on an ambitious project - considered the first of its kind in the world -. To simulate what would be the environment through runaway climate change
The decade of the study, University of Western Sydney Hawkesbury Environment Institute, Australia will have to rub high rates of precipitation patterns and altered consistent with a CO2 "business as usual" global increase in greenhouse gas emissions.
The centerpiece of the study is Eucalyptus external CO2 enrichment experiment, which involved the construction of fiberglass and steel structures six-meter high and 28 to 25 meters in diameter in native forest in Richmond, New South Wales. Structures contain a set of sensors that provide a concentration of CO2 in trees in the rings.
This, scientists say, will create an atmosphere that CO2 is 550 ppm - 40% higher than current levels -. To see how the environment would change living organisms, including humans

This level of CO2 was chosen to mimic how the environment would react in a world where not taken any significant steps to reduce carbon emissions over the next 35 years.
It is anticipated that a 40% increase in CO2 emissions would result in an increase in global average temperature about three degrees Celsius.
An automated computer controlled modular system of the CO2 pumped out of the rings, to account for environmental variability.
Scientists use a giant 43 meter high crane to study the impact on all parts of tall eucalypts, such as bacteria and fungi in soil, the growth patterns of the glass trees and insects that live in the foliage.
many facilities of the institute was funded through an AUS $ 40 million (25 million pounds) of federal grant, the strengthening of an investment of $ 15 million for the University of Western Sydney.
Professor David Ellsworth, who heads the "outdoor" experience, participated in a similar study at Duke University in the United States.
- "This study was planting trees and found that there was less improvement [growth] than we expected high levels of CO2," he said.
- "But there has been nothing like it before on this scale. We are dealing with natural forests and poorer soils. This is a region low in phosphorus and nutrition in the soil, which is the same as the environment in many areas of the world in tropical and subtropical regions.
The first results of the study, scheduled to begin in September, will be published next year.
However, the institute has already conducted a preliminary investigation - the results can be read here and here -. In a small collection of trees in the last 18 months, to test their reactions to warmer temperatures and increased CO2
