OT: 35% More CO2

It was reported on CBS news last night that the level of CO2 in the
atmosphere is now 35% higher than it was at the start of the industrial
revolution. So I guess the question for all you anti global warming rocket
scientists is if man isn't the cause of this increase in atmospheric CO2
levels by burning fossil fuels, then what is the cause? Oh, and back up your
answer with real scientific evidence not the typical name calling you resort
to whenever you can't back up your assertions with facts.

Then please provide the scientific evidence to support your claim.

You mean that news agency reporting that a recent death can be directly attributable to global warming?
I'm curious if uninformed, so tell me what percentage of greenhouse gases comprise CO2?

Because CBS news isn't IMHO a scientific source. I'm looking for some credibility to his claim of 35% higher CO2. He is also demanding that any contradictions be scientifically supported without qualifying his claim to be scientifically proven.

Well, that certainly does it for me. If CBS News said it, it must be true. I mean, if they say it on tv, it has to be the truth, right. It's all the same naysayers who say wrestling is fake. HAH!

Huh? CO2 is a gas in itself, and is comprised of carbon and oxygen. From my very limited knowledge of chemistry, I do not think ANY greenhouse gases are in CO2.
Wouldn't the question be: what percentage of CO2 comprises the atmosphere?
BTW, can anyone describe and list the "greenhouse gases"?
Just curious.

OK, pardon my late nite grammar. CO2 comprises what percentage of greenhouse gases? Get it now? /kram

Well yeah, but...
Please parson my hard headed foolishness, but - so what?
If it's true - you can change it.
And if it's not - who cares what he - or they - say?

AWG has already been debunked, it's only the people that have a religious investment in it that still cling to the failed "science". In a few years it will all be forgotten except for the social outcasts that will meet in somebody's mother's basement and share a few juice boxes while lamenting the loss of their god.

major natural greenhouse gases are water vapor, which causes about 36-70% of the greenhouse effect on Earth (not including clouds); carbon dioxide, which causes 9-26%; methane, which causes 4-9%, and ozone, which causes 3-7%. It is not possible to state that a certain gas causes a certain percentage of the greenhouse effect, because the influences of the various gases are not additive. (The higher ends of the ranges quoted are for the gas alone; the lower ends, for the gas counting overlaps.)[2][3] Other greenhouse gases include, but are not limited to, nitrous oxide, sulfur hexafluoride, hydrofluorocarbons, perfluorocarbons and chlorofluorocarbons (see IPCC list of greenhouse gases).
That last link, the IPCC list, get you another wikipedia page listing 1998 and 1750 levels of many of the gases, and gives as source the 1994 and 1998 IPCC reports which I'm sure give their sources if you track them down.

Im rather curious if they could accurately measue atmospheric CO2 at the start of the industiral revolution, in the first place. Gunner

The Greenland Ice Core Project boreholes provided trapped air samples going back over 100,000 years. Notice what they think of the results.

Well, first you need to back up your claims with something a little more reliable than a report on CBS News.

So, will the liberal networks try staging global warming? How will that work? Hold a Zippo under a thermometer at the north pole?

Save the Earth: Get rid of that damned anthropogenic ocean which creates all those horrible greenhouse gases!
Oh, wait a minute. WE didn't create the ocean...
