Straw man science: keeping climate simple; watch the pea..

By Eco Guy 2:57am 27th November 2012
The conversation has just published a rather incorrect article claiming that none of the human produced Co2 is absorbed by the natural Co2 cycle, we blow it out the water.

See the offending article here , to quote:

"We produce a modest percentage of all CO2 emissions. But the extra emissions aren’t absorbed by the carbon cycle, so CO2 builds up in the air. A small rise each year has resulted in a 40% increase of CO2."

Wrong, yes Co2 has gone up, but it has been going up for the last 50m years, see here. Although, as noted in the paper, working out the exact source of Co2 and its relationship is very hard to do, as each source does not have a distinct Co2 'fingerprint' - rather there is a lot of overlap as different sources and sinks inject and consume different isotopes of Co2 in different ways.

As for the extra Co2 emissions from man not being consumed in the carbon cycle, it is well know that Co2 is growth promoter in plants. So much so that commercial operations growing plants often inject Co2 into their greenhouses to speed growth. Also it is known that the biosphere is blooming, and that the African Savannah's are turning into forests.

Where exactly is this covered in The Conversation's article? The measured and observed truth to inconvenient for you? See where the pea goes..



Also I think its true to say that The Conversation are the one's here who have constructed a straw man by cherry picking quotes and not answering directly the point raised, nor giving Alan Jones a chance to respond to their article prior to publication - shame on you!
