What do CO2 and 9/11 have in common?
I have been having a conversation that started about a week ago with some friends on FaceBook, concerning an article that ran on Financial Times web site. It’s behind a paywall, but you can also find it in The Wall Street Journal and at Fox Nation. But I am not really sure that lack of information is purely the problem. Some of the problem is people reading headlines and assuming they mean one thing, then to actually read the content of the article and find it is not as it seems. “U.S. Greenhouse Gases Drop to 15-Year Low” This was clearly a misleading Headline.
Below is the outline of the conversation from FaceBook “Quoted” and my Response.
“WE are not the predominant causers of CO2 in the atmosphere. Human kind and all of what WE produce, filling all of our needs and wants, only counts for less than 2% of the CO2 produced on a global scale. Rain forest decomposition counts for more CO2 than WE could ever even try to produce…so…why don’t we cut all those trees down and use them before they fall over, decay naturally, and release even more CO2? Oh, wait, we already have ignorant jackazzes doing that, releasing long buried viruses from old grove root systems that could, ironically, kill us quicker than “global warming”.”
You are absolutely correct, we are not the predominate producers of CO2. The figure of 2-3% is correct. However, the normal background CO2 cycle is roughly 439 gt. (gigatons) output from land and forest and 332 gt. from ocean output. That is a total of 771 gt. being put into the atmosphere and then 788 gt. is being reclaimed. That shows that 17 gt. is excess being reclaimed. Problem is that as the earth warms the excess being reclaimed will diminish until more CO2 will be entering the atmosphere than being recovered. One saving grace!… There is an 800 year lag of earth warming and CO2 recovery. (i.e.) CO2 recovery lags behind temp increases by 800 years.
Explanation of CO2 lag here: What does the lag of CO2 behind temperature in ice cores tell us about global warming?
But here is the crux of the problem… 2007 IPCC AR4 Synthesis Report found here IPCC AR4 Synthesis Report you can see that the human contribution of CO2 the 2-3% is 29 gt.that means that 12 gt is NOT getting reabsorbed via, Oceans and Forests. This is the 1.5-2.5 ppm. rise we see in Global CO2 content yearly.
