CO2 levels have stayed approx. constant since 1850

(PhysOrg.com) -- New data show that the balance between the airborne and the absorbed fraction of CO2 has stayed approximately constant since 1850, despite emissions of CO2 having risen from about 2 billion tons a year in 1850 to 35 billion tons a year now.

New data show that the balance between the airborne and the absorbed fraction of carbon dioxide has stayed approximately constant since 1850, despite emissions of carbon dioxide having risen from about 2 billion tons a year in 1850 to 35 billion tons a year now.

This suggests that terrestrial ecosystems and the oceans have a much greater capacity to absorb CO2 than had been previously expected.

The results run contrary to a significant body of recent research which expects that the capacity of terrestrial ecosystems and the oceans to absorb CO2 should start to diminish as CO2 emissions increase, letting greenhouse gas levels skyrocket. Dr Wolfgang Knorr at the University of Bristol found that in fact the trend in the airborne fraction since 1850 has only been 0.7 ± 1.4% per decade, which is essentially zero.

The strength of the new study, published online in Geophysical Research Letters, is that it rests solely on measurements and statistical data, including historical records extracted from Antarctic ice, and does not rely on computations with complex climate models.

This work is extremely important for climate change policy, because emission targets to be negotiated at the United Nations Climate Change Conference in Copenhagen early next month have been based on projections that have a carbon free sink of already factored in. Some researchers have cautioned against this approach, pointing at evidence that suggests the sink has already started to decrease.

So is this good news for climate negotiations in Copenhagen? “Not necessarily”, says Knorr. “Like all studies of this kind, there are uncertainties in the data, so rather than relying on Nature to provide a free service, soaking up our waste carbon, we need to ascertain why the proportion being absorbed has not changed”.

Another result of the study is that emissions from deforestation might have been overestimated by between 18 and 75 per cent. This would agree with results published last week in Nature Geoscience by a team led by Guido van der Werf from VU University Amsterdam. They re-visited deforestation data and concluded that emissions have been overestimated by at least a factor of two.

This climate change hoax is based on computer models programmed by individuals that promote the propaganda. Ten years ago, all their models suggested sharp increases in climate temperatures...the exact opposite has happened based on hard, real-world data. I would like to see a comparison of the BTUs stored in the oceans, lakes and rivers of the planet to the BTUs produced by mankind. I suspect mankind BTUs wouldn't approach 1% of ocean stored! To warm the planet, the oceans will have to be warmed and that will only happen by the sun. The vast majority O2/CO2 exchange takes place in the oceans by plankton. CO2 is plant food...increased CO2 levels will grow more plants. How can that be a bad thing????

Plain and simple, this hoax is being promoted by a group of elitist that believe they should be the ruling class over the peoples of the world.

Hey, Photobucket...a couple of research projects for you there...show us the facts! :D

Your point about the ocean's plankton being the major source of the world's oxygen is what I was taught as well. The amount exchanged by trees and other dryland vegetation is small by comparison.

One thing is certain, given the earth's stable areas of land and water, it would be highly irregular for that CO2 -> O exchange ratio to change very much, if at all, over a short time frame.

It is amazing how much established and verified scientific fact needs to be discarded to make room for popular, new theories.

Antarctica Glacier Retreat Creates New Carbon Dioxide Store; Has Beneficial Impact On Climate Change

ScienceDaily (Nov. 10, 2009) — Large blooms of tiny marine plants called phytoplankton are flourishing in areas of open water left exposed by the recent and rapid melting of ice shelves and glaciers around the Antarctic Peninsula. This remarkable colonisation is having a beneficial impact on climate change. As the blooms die back phytoplankton sinks to the sea-bed where it can store carbon for thousands or millions of years.

Reporting recently in the journal Global Change Biology, scientists from British Antarctic Survey (BAS) estimate that this new natural 'sink' is taking an estimated 3.5 million tonnes* of carbon from the ocean and atmosphere each year.

*The 3.5 million tonnes of carbon taken from the ocean and atmosphere is equivalent to 12.8 million tonnes of CO2.

Global carbon dioxide emissions from fossil fuel combustion and land use change reached 8.7 billion tonnes of carbon in 2007.
