What do RIU members think of this issue? Where do we weigh in on it?
Man made carbon emission causes AGW?

Arent you the guy who thinks CO2 causes cooler temperatures?

Aren't you the guy who posted those pictures of kids with guns, wearing pajamas and pots on their head?
That cracked me up...thanks again for that.

The use of "causes" makes it an unanswerable question, noone knows if we "cause" it, because for the minute, AGW is a hypothesis on the long road to becoming theory, which is a LONG way from becoming fact.
I would have posed the question "Do you think man made carbon emissions influence Global Warming?".

Maybe the poll question "Do you think man made carbon emissions contribute to Global Warming?" or
"Do you think carbon contributes to Global Warming?"

Hey that's me. Nowhere am I suggesting the cause.

I'm unclear in re one thing, and it's staying my hand from hitting a button.
Do I think industrial CO2 is the sole cause of global waring? No. Do i think it contributes? Yes. To what degree? I don't know.
Poll needs more choices imo. cn

Actually, it makes if very easy to answer: no.
Your question is much better. Yes, I think they do. However, this still ignores other factors that may contribute - some of which are also man-made - like massive deforestation and all the other large-scale changes we can easily and quickly make to our environment with modern technology.

I'm searching for how to edit the question. Maybe this poll is a fail because of the question. First poll for me. I would recreate it as "Do you think carbon contributes to Global Warming?" I'm open to suggestions if edits possible. I'm interested to see our members views.

If you'd posed the question like that I'd have answered: I think man contributes and possibly accelerates cyclical global warming (it is proven to be cyclical as an aside from the AGW debate), but to what degree does this influence extend I'm not sure.

I think you as OP have the ability to edit the poll. I cannot reach it. If you can't, a global or admin might be needed. Chiceh is a global who has always impressed me with her service spirit and general pleasant demeanor.
But imo the simplest fix is to add more poll options including the bland "don't know" as well as some in-betweens, like "I think it affects global warming but is not the sole cause" and the eternal "I like turtles" ...

440 GT from the Biosphere and 330 GT from the ocean and 10 GT from man. Roughly 12% of atmospheric CO2 is man made. CO2 comprises .04% of the atmosphere.
Roughly .005% of the atmosphere is comprised of man made CO2. Five one-thousandths of one percent. That is a doomsday scenario!
Please, do tell, how is this warming the globe.

the real question is "Is there Global Warming at all?" since the current cold spell is bringing back the 1970's new ice age rumors. this is why the touts are moving away from "Global Warming" and embracing "Climate Change"
your numbers are wrong though,
CO2 currently makes up about 3-4% of atmospheric gasses, not .04% at .04% CO2 concentrations, plants would not be able to survive.
nobody is sure exaclty how much CO2 comes from the "biosphere" since termites bacterium in swamps, and wild herbivores dont fill out census cards or keep journals of their flatulence
nobody is sure exactly how much CO2 the ocean has lost from it's massive store of gasses since the best estimates of oceanic gasses are only estimates based on averages, but the oceans warm and cool in sections, not like a bowl of jello in the fridge overnight.
you didnt even mention the geological sources of CO2, nor can anyone accurately estimate the amount of CO2 eliminated from the atmosphere on any given day by photosynthesis from land and sea bourne plants and algae.
the best anyone can say right now is, over the last 60 years CO2 concentrations in the atmosphere have increased by .5% to 1% overall from 2.5% to 3-4% +/- .3-.5% all things considered, it's not doomsday yet, and it certainly isnt enough to cause the nightmare global crisis the touts are screaming about.
CO2 concentrations have been MUCH higher and MUCH lower in the past (6-7% during the huge glaciation before last, round about 40,000 years ago, to as low as 1.5% in the cambrian explosion) and the earth still endures.
right now im more concerned about the possibility that aliens might invade, and fo9rce us to work in their underground vespene gas mines than global warming.

Dude, everyone knows Vespene Geysers emerge above ground level, what's this "underground" shit your touting? It sounds like pure crazy talk to me.

Doc, to the best of my knowledge the numbers are good. 400 ppm equates to .04% of total atmospheric co2 measured from all sources, man made, biomass and ocean. Of course they are scientific best estimates, but most any source from either view will be in the ball park. And I agree that co2 ppm historic range is wide. If the co2 # I'm quoting is wrong than let's cite an accurate one. Here's a quick google, hopefully reputable. http://www.ucsusa.org/publications/ask/2011/atmosphericco2.html I think the benchmark is the one from Hawaii, they've been consistently monitoring and releasing data. Point is, the actual percentage of co2 in atmosphere is tiny. Even smaller is mans contribution. Estimates bantered are in the 10-18 % range of total co2, which again is currently 400ppm, .04% of total atmosphere.
