Study: Lots Of CO2 Is Literally Making The Earth GreenerEnvironmental | 208056 hits | Apr 25 1:44 pm | Posted by: N_Fiddledog  The study is the largest of its kind and was written by 32 scientists from 24 colleges and universities in eight countries. It used three long-term satellite records of plant area and 10 different global ecosystem models to measure increasing plant growthCommentsview comments in forum Page 1 2 You need to be a member of CKA and be logged into the site, to comment on news. |

what? it isn't POISON?
At high concentrations, it is. Check WHMIS data.
And what all the articles recently about this study neglect, is another experiment that showed in the short term plants will grow faster; but they use up soil nutrients rapidly and die sooner.

CO2 is a trace gas in the atmosphere, so unless it's H2S, it isn't going to do anything but green the planet.

CO2 is not toxic at any levels man is capable of adding to the global atmosphere.
One more time then...

No one claimed that. uwish claimed it wasn't a poison. With no caveats. Since CO2 replaces oxygen in the blood, it can cause poor decision making at low concentrations, and asphyxiation at high concentrations. Therefore, it is a poison.

I see so it's kind of like peak oil then, is it?
Question though: What happened during all the geologic periods in the past when temperatures, and CO2 leverls were much higher than they are today? I'm guessing it took a little greenery to feed a dinosaur. So why didn't the great deserts of destruction happen back then from soil nutrition leeching by CO2?
Also I notice in that press release he's fond of words like "perhaps" or "may be."

thank you, next time I will add the caveat.
I wonder, what effect high Co2 levels had on plants before they evolved to use lower concentrations . . . .hmmmm. . . .
If you prefer. For example what happened during the Holocene warm period. I heard we did pretty well as a species during the Roman and Medieval warm periods. Apparently plants survived. When exactly are you hypothesizing that this evolution of plants to use lower concentration of CO2 took place?
As to previous extinction periods of millions of years ago, nobody knows what caused them. Stop pretending you do.
We do know there have been higher levels of CO2 with higher temps existing for hundreds of thousands of years.

It was your hypothesis, not mine.

Stop attributing to me things I have not said.

Not according to that graph. It's scaled in the hundreds of millions. The part we occupy would be the tiniest sliver on the lower right. When Co2 is the lowest.

If you don't say what you mean, you can't mean what you say.
