No Rise of Atmospheric Carbon Dioxide Fraction in Past 160 Years, New Research Finds
ScienceDaily ^ | Dec. 31, 2009 | staff

Most of the carbon dioxide emitted by human activity does not remain in the atmosphere, but is instead absorbed by the oceans and terrestrial ecosystems. In fact, only about 45 percent of emitted carbon dioxide stays in the atmosphere. However, some studies have suggested that the ability of oceans and plants to absorb carbon dioxide recently may have begun to decline and that the airborne fraction of anthropogenic carbon dioxide emissions is therefore beginning to increase.

snip

To assess whether the airborne fraction is indeed increasing, Wolfgang Knorr of the Department of Earth Sciences at the University of Bristol reanalyzed available atmospheric carbon dioxide and emissions data since 1850 and considers the uncertainties in the data.

In contradiction to some recent studies, he finds that the airborne fraction of carbon dioxide has not increased either during the past 150 years or during the most recent five decades.

I thought that after the Congressional hearing a few weeks back that Ocean Acidification through Man-Made Atmospheric CO2 was the new cause celebre.

>> SP formed a committee to examine the effect on the state of Alaska of the melting permafrost, which WAS happening.

I don’t think she ever fell in with the “gotta do SOMETHING” crowd. <<

Or the 100% of it is all Humans fault and we should shoot ourselves in the collective foot over it...

Ammo against this crowd is located here.

Upshot: Humans' CO2 contribution to the greehouse effect is 0.117%.

Despite the fact that Ocean life Thrived even between the Triassic and the Cretaceous when the CO2 levels were far higher than they will be today or even in 1,000 years of more coal burning.

No the Oceans will become to acidic for critters to form shells and everything will die, yeah if that were the case we would have no Cretaceous ocean fossils of shelled animals like clams and Bivalves. Bunch of Junk science hooey...

Let's just be silly here and suppose that increased solar activity warmed the earth. That would result in an increase in the temperature of the water in the oceans. When water is heated it releases dissolved gases like CO2. That would result in higher atmospheric CO2 levels.

Gee, that might make sense based on the available (and unadjusted) data. But since man is not the cause, that can't possibly be true.

This is not new. This is properly called the CARBON CYCLE and anyone who’s had even a rudimentary science education has learned about it. <<

Some days I wish I had a device that could remove all of the Carbon from any object, I would take it over to where the Greenpeace flunkies setup every day and politely ask them if they would like to remove all of that nasty Carbon from them, when they said Yes the resulting satisfying splash of what remains of their body sloshing against the pavement after all of the carbon their body was removed would make up for their annoying antics they have subjected me to for the past several years....

But.....but.....but....Lubchenco had water and vinegar and dry ice and demonstrations and all sorts of other good stuff to prove her point.

“Wasn’t it Gore who, when confronted with the “laws of physics” stated that “we’re in power now, we should repeal these laws”?”

In the Wonderful World of Post Modern Deconstructionism, science is a “social construct”. Which means that science no longer depends on observations, it depends on what the Party decides.

Baking Soda and Vinegar may simulate the eruptive properties of a Volcano, but they don’t model the hundreds of millions of metric tons of scorching hot lava and all of the volatiles released.

Plus vinegar is acidic, and different acids react to different things, Calcium Carbonate is what makes up sea creature’s shells, weak carbonic acid is going to have far less of an effect on it than acetic acid. Plus you can have a acid with a higher PH that will react less than one with a lower PH depending on the material that you are trying to dissolve.

I burn this to stay warm and put carbon in the air.

Which was created by something that took the carbon out of the air long ago. CO2 is heavier than air so it would tend to stay close to the ground, where I plant this...

and this...

..to take it back out. Why have Copenhagen conferences when it's that simple, more or less?

Heretic, High priest Algore will be after you now.

I am, I admit.

Call me crazy, but I firmly believe that carbon will recycle endlessly in the earth's atmosphere, oceans and rocks, without ever reaching a point where the recycling feedback loop that has operated without a hitch for the last 4.5 billion years or so will be overwhelmed and send the atmosphere into an unstoppable warmup.

If the planet made it through the Cretaceous without doing so (when CO2 levels were many factors higher than today, and there were no ice caps), it surely will make it through today's conditions.

Am I going to hell now ?

If you haven’t seen it, here’s her demonstration

http://globalwarming.house.gov/pubs?id=0014

scroll down to the two videos of her performance.....oceans are 30% more acidic than before fossil fuels.......worst in 20,000 years.....etc......etc......

We are seeing the opening act of the setup. Since it is becoming increasingly obvious that the earth has not been warming, the new line is that it will son happen rapidly.

Yes, yes,of course you are right.

I suppose we should be happy that instead of trying to control the vast atmosphere; we know only have to control the chemistry of the world's oceans.It'll be so much more manageable.

Clearly Al Gore didn't study chemistry, either.

How else could all those bigwigs and fake warmers have an excuse to visit Nopenahgen on their corp jets and eat tons of caviar on our nickel? They're so much smarter than all us fly-overs they deserve the perks.

If we are talking about Ocean PH levels, things like Fertilizer runoff and industrial pollution with non-naturally occurring chemicals would have a greater effect on it than CO2. Plus the warmer the ocean the less CO2 it can hold.

But if we were worried about the former we would have to call Commie China out on it’s horrible environmental practices.....

From the same Science link: "Global Warming From Carbon Dioxide Will Increase Five-Fold Over The Next Millennium, Scientists Predict"
Check this quote: "Scientists at Liverpool, however, have found that if all conventional coal, oil and gas carbon reserves are exhausted, the excessive amounts of carbon dioxide in the atmosphere will begin to alter the ocean’s natural chemistry and hinder its ability to absorb and exchange the gas."
Are they completely insane? If all conventional reserves are burned there might be a problem? Sheesh - oh - unsurprisingly the research is in collaboration with East Anglia ... ;-)

Well, the estimated amount was 750 gigatons not too long ago with a 150 gigaton/year turnover, meaning that the residence time of a molecule of CO2 in the atmosphere is about 5 years.

“the Staff failed to grasp that the last 50 should be mentioned first, because if the fraction has not increased in the last 150 years, OF COURSE it has not increased in the last 50!!!!”

I am not a scientist or a mathematician, but if the fraction decreased by 5% during the first 100 years of that 150 years and then increased by 1% during the last 50 years of that 150 years, wouldn't you have a situation where the fraction has not increased in the last 150 years, but HAS increased in the last 50?
