Parts per million, folks. We also urinate. Doesn't mean that we could survive in piss ten feet deep. Thanks for the science, Rush!

"if it was poison it wouldn't be part of the way we stay alive"...wow, people really listen to this retard??

@victorsossa It is so simple dude. If all plants and trees can process x amount of CO2 and there is an equlibrium. What happens if the amount of CO2 doubles to 2x as a result of automobile and industrial exhaust? I second the motion by evilsoxkitty. Let this Rush idiot try to survive on CO2 for an hour. That might stop him poisoning the minds of simple Americans with his idiotic rants.

@13fanboi They might not have taught it at your high school, but everything I said was correct. Plants need CO2 during the day to perform photosynthesis. Maybe I should emphasize "photo," as in, when there's light. At night, plants continue to eat sugars generated during the daytime; a process which vents CO2.

Regardless of the science lesson, it's pretty stupid to argue that anything humans exhale, excrete, or perspire can't be harmful in overabundance, which is what Rush is trying to do.

@victorsossa It is part of the way we stay alive. We exhale CO2 as waste. Plants use it and exhale O2 as waste. We breath O2. That is what Rush is talking about.

@jizzmatic2000 Maybe things have changed since I took biology in highschool,but last time I looked plants produce oxygen as exhaust,not carbon dixoide. That is why the majority of life on earth is possible. Plants need our waste gas and we need their waste gas. There are places on earth where life exists on other gases(deep ocean methane seeps,volcanic vents),but Rush is right; CO2 is a huge part of the equation for life on earth.

You cannot just look at old datasets and say 'it was so hot then, that the ice caps melted' and 'it was so cold then that the glacial caps covered 40% of europe'

Because those periods were punctuated by increased solar activity, particulates, glacial reflection etc

However this current trend, is viewed directly with more accuracy and can be tested at any time for verification.

There is no other reasonable explanation, so kindly accept the conclusions of experts that it really might be us.

I think you are excluding the whole issue which has been raised.

Scientists are trying to get it through that CO2 levels have shot up in the past century due to our industrial activity.

The earth is getting warmer (on average) year on year with no viable alternative explanation other than the CO2 increase.

They have shown that CO2ppm is the highest on record, and that solar output is so low that its actually abnormally 'cooling' us currently.

Past records are explainable, THIS isnt.

[jizzmatic2000]

@glenndough79 Sort of. During the day, when a plant is performing photosynthesis, yes. However, at night, when that plant continues consuming its produced sugars, it's actually exhausting CO2.

Then add the fact that we're actively generating more CO2 as we're destroying acres of forest on a daily basis, and you can see why there might be a problem.

[glenndough79]

CO2 is plant food.
