The University of Bristol announced a new study by Dr. Wolfgang Knorr to be published in Geophysical Research Letters. This study will likely set the climate world on its ear. Dr. Knorr claims in his new study that airborne fractions of CO2 has increased only 0.7 +- 1.4 % per decade, which is essentially zero. Dr. Knorr based his findings on actual measurements and statistical data, including historic records from Antarctic ice. Unlike most studies, it does not rely on model computations.

"But Dr Wolfgang Knorr cautioned that the world should still be trying to reduce carbon dioxide emissions as part of any climate change deal decided in Copenhagen next month.

He pointed out that the amount of greenhouse gases in the atmosphere is still increasing, even though half is absorbed by the Earth. Also there are fears that the oceans and soil become saturated and are unable to absorb any more CO2 in the future."

Most people that reply to a thread offer a contribution. Parroting the OP is NOT a contribution.

Of course, this landmark paper by a renowned scientist, totally debunks the findings of your "nephew" as you've described his work.

The title of this thread is extremely misleading. The paper doesn't say that there has been no increase in amount of CO2 in the atmosphere, rather it says that the the fraction of C02 that is not being absorbed (~40%) has stayed about the same, meaning carbon sinks probably aren't as saturated as we previously thought. This isn't going to "turn the climate world on it's ear" because all it tells us is that we can expect similar absorption rates in the future rather than declining ones.

Gill

Not misleading at all... it clearly states that airborne CO2 has not increased since 1850. Does the title state as you claim "no increase in the amount of CO2 in the atmosphere?" No it doesn't does it??

The percentage of airborne CO2 is NOT increasing as every climate paper is claiming if this paper is correct. Any person not saturated in alarmist Kool-Aid would absolutely believe this paper turns the climate world on it's ear.

I think most people would interpret those two phrases to mean the same thing, but, whatever there's no point in arguing this.

Tell me what is the significance of this paper? Why does the fact that there's been no change in the airborne fraction of CO2 "turn the climate world on it's ear"?

Gill

Uhhh, do I really need to explain the significance of this??? I'm really quite amazed that you would even ask.

The entire theory that man is causing the temperatures to rise is that we are increasing the amount of CO2 in the atmosphere. If the percentage of CO2 in the atmosphere is not increasing, a big hole is blown in the theory. If the percentage (fraction) is staying relatively stable, then that means the earth and oceans are absorbing a much larger percentage than previously thought. Global warming, as hypothesized by alarmists, cannot happen if the AMOUNT of CO2 does not increase in the atmosphere. In other words, the fraction or percentage of CO2 must increase in relation to the other atmospheric gases for warming to occur as hypothesized.

Except the amount of CO2 in the atmosphere has increased, we know that from observations Mauna Loa as well as other sites. Dr. Knorr is not saying that there hasn't been an increase in the amount of CO2 in the atmosphere, what he is saying is that there has been no change in the fraction that is being absorbed vs. airborne. For example:

1850: 1,000 tons of CO2, 40% is airborne, 400 tons of airborne CO2

Today: 1,000,000 tons of CO2, 40% is airborne, 400,000 tons of airborne CO2

*The numbers aren't correct but they're just used to demonstrate the point

The amount of CO2 to in the atmosphere dramatically increased but the fraction that was airborne stayed the same hence why the the article says:
