It's actually useful, because as soon as I come across a line in a glbal warming tract that reads something to the effect that "CO2 is fgood for plants" or "CO2 is non-toxic" then I know I'm dealing with someone who isn't very scientifically credible on the subject.]

At 10,000 parts per million of CO2 in the atmosphere you might start to get drowsy. The current estimated level of CO2 in the atmosphere is 385 ppm. Let's say that doubles this century to 770 ppm it's still less than 1/10 of the amount of CO2 required just to make you dizzy. You like Wikpedia, as I recall. It tells me CO2 doesn't become clearly toxic until 50,000 ppm. that's 65 times as much as doubled current levels, or 130 times current levels. Gigantic dinosaurs thrived at about 7 times current levels of carbon dioxide.

In other words...No. CO2 is not toxic at any sane estimate of what man might conceivably put into the atmosphere. But go ahead science boy. Prove me wrong.

As far as doubting CO2 is good for plants, you're joking right?

You sure know how to miss a point.

I dont see how he missed the point?
And whats the point? dont dare go against the theory of man made global warming cause you guys will scream and yelll we are all crazy and choots with bush and Harper to ruin mother Earth. GFYS

You're too late and only get the Runner up prize. In thhe event Fiddle can't fulfill his obligation as Miss A Point, you will bare sole rsponsibility to represent.

The Point: Clearly described in thread.By itself, CO2 may not be "Toxic", but that does not mean it is "Harmless".
