So you are suggesting that the rise in atmospheric CO2 is not from anthropogenic sources? And you are suggesting this because CO2 has been produced by naturogenic sources in the past?
Besides the complete logical failure there (this man has blonde hair, therefore all men have blonde hair) there is the unaddressed point that isotopic analysis shows that virtually every molecule of CO2 added after the beginning of the Industrial Revolution comes from the combustion of fossil fuel. How, exactly, is that addressed by your Swedish birch leaves.
There is more evidence to support the theory that the current rise in CO2 is attributable to the MWP than to mans sources. Mankind is such a vanishingly small amount of the global CO2 budget that the claim it is all from mankind is simply ludicrous.
And this fellow claims to be a Phd Geologist. LOL
The Gigaton Question: How Much Geologic Carbon Storage Potential Does the United States Have? | Science Features
On May 9, 2013, the level of carbon dioxide in the atmosphere officially passed the 400 parts per million mark, an atmospheric concentration of carbon dioxide not seen in more than 800,000 years, according to the National Oceanic and Atmospheric Administration. In 2011 alone, the United States emitted 5.5 metric gigatons of CO2 from energy production, and the world released a total of 31.6 metric gigatons, according to the U.S. Energy Information Administration.
In any realistic discussion of ways of solving the looming problems of climate change due to the increasing levels of CO2 in the atmosphere, carbon sequestration must play a role. Carbon sequestration is a method of securing carbon dioxide (CO2) to prevent its release to the atmosphere and contribution to global warming as a greenhouse gas. Geologic carbon sequestration is the deliberate storage of CO2 in porous and permeable rocks and involves injecting high pressure CO2 into a subsurface rock unit and displacing the fluid that initially occupied the pore space. The USGS has been working for the past several years to help inform that discussion with the best available science on carbon storage potential in the United States.
On Tuesday, June 25, 2013, USGS added a significant piece to the puzzle with the release of the first-ever comprehensive assessment of geologic carbon storage potential for the entire United States, with a mean estimate of 3,000 metric gigatons of potential storage. Along with the regional assessments of biologic carbon sequestration that are ongoing, this national geologic carbon sequestration assessment gives land and resource managers a powerful new tool to help determine the appropriate actions to take on mitigating climate change.
Oooooh, a whole 5.5 gigatons. Wow. In an atmosphere that weighs quadrillions of tons, a gigaton is such a vanishingly small amount that it requires specialized instruments to measure it. And to date, no one has been able to show the slightest effect of that vanishingly small amount of CO2.
And lo and behold take a gander at this, here is where all that CO2 is coming from and wouldn't ya know it, it isn't coming from man. Surprise, surprise, surprise! Must suck to be wrong all the time like you clowns are....
