Scientists are very worried from their data that shows increasing CO2 levels that are growing faster than anticipated and faster than the growth of emissions.
CO2 rose at record levels in 2006, the fourth of the past five
years showing increases that are not in line with the slow increase
in man's emmision of the greenhouse gas. It would be explained if
there had been a volcanic eruption each year somewhere on the
planet.....but there has not been even one.
Peter Cox, a climate change expert at Exeter University, said: " The
concern is that climate change itself will affect the ability of the land
to absorb our emissions."
They are worried that this means we have less time than they thought
to change our polluting ways before huge changes in the climate occur.
