Apolitical;
You post;
"there is no other extraneous variables of massive CO2 sources other than rapid industrialization and burning of fossil fuels."
Let's take just one of the thousands of your "supposed" non-existent extraneous massive CO2 sources. Mammoth Mountain, CA and the Horseshoe Lake tree kill area. The total discharge of 50 -150 tons per day of carbon dioxide (CO2) gas being naturally released. Don't camp the in the kill area, don't dig a hole and defiantly don't lay face down on the ground; it will kill you. So let's look at what Exxon paid for;
In the last10,000 years
1500 volcanoes on land known to have been active
Even larger number of submarine volcanoes exact number is unknown
600 volcanoes that have had known eruptions during recorded history
50-70 volcanoes are active (erupting) each year
At any given time, there is an average of about 20 volcanoes that are erupting
(http://www.volcanodiscovery.com/en/volcanoes/faq/how_many_volcanoes.html)
Well golly gee must-ta been really expensive for Exxon paying to put all those pesky Volcanoes on the planet? Let's not even take into account the Earths natural release of Methane which tests 20 times as dense as Carbon. Wow, think of all the work it took for Exxon to seed so much Methane just to have extraneous paid for sources!!
Once again if you use Gore's 51 year sampling of carbon output it fits nicely at the peak of Earths last warming trend of Earth. The current warming trend started in the ballpark of 20,000 years ago, not only does the Vostok ice core show this but a multitude of other separate extraneous studies.
At least I'm not jumping onto the band wagon that we are on the verge of another ice age using the Vostok ice core data. As for your Exxon theory the core was a collaborative ice-drilling project between Russia, the United States, and France at the Russian Vostok station in East Antarctica
Then lastly you once again post some ignorance of your concept of Buffoons. I find it extraordinarily Funny how Obama???s Cap and Trade is being blocked by both the Democrats and Republicans!!
