CO2 study not climate's 'magic bullet'
Thu, 12 Jul 2012 9:19a.m.
A study into global warming has revealed our planet is now absorbing a much larger amount of carbon dioxide than it was 25 years ago.
The finding poses many questions - particularly whether the increase is temporary. If so, reducing CO2 levels may get even harder in years to come.
New Zealand scientist Sara Mikaloff-Fletcher who was involved in the study says it’s been known for quite sometime what happens to CO2 released from burning fossil fuels.
“About half of it actually stays in the atmosphere and the other half is naturally taken up, part of it is going into the oceans and part of it is going into the biosphere which means it’s taken up by land ecosystems by plants and soils.”
Dr Mikaloff-Fletcher says there was a big increase in CO2 absorption by the earth’s biosphere in the 1980s.
However she says although it’s good news, it is not the ultimate solution to this planet’s woes.
“This is not a magic bullet that’s going to solve all our climate problems. The uptake of CO2 by land defintely is good news for us - it helps to slow climate change by taking up CO2, but… at some point you reach a limit beyond which the land cant take up very much additional CO2.”

After watching your global warming religious report last night on the 6 o'clock news I decided to do my own research and found the latest paper published in Nature which shows that the earth has been cooling for the last 2 million years. I was quite disgusted by your level of reporting and lack of serious research into news items, if you must put out news stories on global warming religion then I suggest that you also balance it with the latest science and give the public the chance to decide for themselves which is the religion and which is the science.
