uk longchamp sale uk longchamp sale Fossil fuel the prime suspect

Australian scientists have pinpointed human use of fossil fuels, such as burning petrol and coal, as the prime suspect in a large increase in greenhouse gases.

CSIRO scientists have found nearrecord growth in carbon dioxide, the most important gre uk longchamp sale enhouse gas, in the atmosphere in the past two years.

They compared that to previous peaks in 1994 and 1998. In those years, other gases including hydrogen, methane and carbon monoxide which are released by wildfires, were also recorded. Scientists concluded that huge wildfires in the tropics had released massive amounts of carbon dioxide, pushing levels up sharply.

But in the CSIROs latest measurements, the trace gases are not there in the same proportions. This led scientists to rule out natural greenhouse gas releases, such as those from oceans and forest fires, and conclude that fossil fuel use was the most likely culprit.

By a process uk longchamp sale of elimination, with our current knowledge, fossil fuels must be a prime suspect, said Dr Roger Francey, from the CSIROs Atmospheric Research.

Meanwhile, a Queensland report says global warming will lead to catastrophic cons uk longchamp sale equences for some of Australias most precious rainforests and cause the extinction of many of its animals and plants. The report, prepared by the Rainforest CRC a coalition of 13 scientific agencies including the CSIRO and James Cook University says the impact of global warming on Queenslands tropical rainforests could be particularly severe.

The report comes on top of another report last month which said that global warming could kill much of the Great Barrier Reef through coral bleaching during the next 50 years.

The latest report, Environmental Crisis: Climate Change and Terrestrial Biodiversity in Queensland, says a rise of as little as one degree would kill some Queenslands rainforest species, such as the Bellenden Ker Nursery frog. Further rises would kill more, including the spottedtail quoll, the Atherton scrubwren and the Thornton Peak skink. uk longchamp sale
