Except this time you havent got any have you? You cant come up with any evidence outside of GW websites that shows CO2 is not beneficial to plants. So all you can do is resort to insults. Yep, as I said, childish Ian.

"Super-optimal CO2 reduces..." Super optimal anything is going to have a negative effect. Super optimal water is called drowning, super optimal oxygen is called hypoxia. So, as stated in my link, CO2 at 1000 PPM is the optimal level for plant growth. And what are we talking about with AGW? 700PPM. So its well within even the optimal level, let alone any crazy ass figure used to poison plants.

Yeah, some plants dont. So what? This doesnt detract from the fact that most do, and at levels far higher than we are suposed to be worrying about. So, Fisticuffs, what have you shown us? That you cant follow basic instructions about using non AGW propagandist links? That you are so wrapped up in your beliefs about how bad CO2 is that you cant even recognise the fact it has been used for decades to boost crop production? What a feeble lame ass attempt at a refutation! :laugh:

Getting even more feeble.... So, I have provided NON PARTISAN irrefutable evidence that CO2 (at up to 1000PPM) is beneficial for crop production. I have shown that an entire industry exists in order to provide this to farmers and home growers alike. (And you know farmers, if it didnt show a profit they would spend the cash). And that governments recomend it. So, thats one of your arguments slayed. Now for the "was it warmer during the last 10000 years and by how much" question. I am sure you already know this to be a fact so we dont need to provide the AR1 graph, Vostock and Greeland ice core data as well as allegorical evidence. Finally, feed backs. And this is where it gets tricky. Your position is that the 1.2 degrees C rise that CO2 will theoretically give us will be amplified by water vapour feedbacks thus giving us a 4 degree rise. (This is after all the IPCC position). So, what real world evidence is there for this? Well, look back in time. Mankind has already added 100PPM, a 35% increase, and what has happened during that time? 0.7 degrees C warming of the lower troposphere. No feed back. Of course you know that the effect of CO2 is non linear such that small amounts added intially to the atmosphere have a far larger effect than large amounts added later, so if we add 100% more CO2 it is very likely that even if CO2 does cause warming in the rclimate system* we will only get the expected lower troposphere rise of 1.2 degree C. Of course during the addition of that 100PPM severe or extreme weather hasnt increased at all so its equally unlikely that it will do when we double CO2. Which we will by the way. Now I know you can throw links about that show by using computer models that extreme weather HAS increased and so on, but since they are models and not the real world their 'evidence' counts for nothing. *Note, I say 'even if' because it is thought that CO2 has been responsible for stratosphereic cooling. If this is the case, and the net energy addition to the system is zero, then it cant be said to be warming. Also historic/gound based temperature data is too unreliable. Satellite data is better of course, but we dont have a long enough record and what we do have shows 10 years of stasis. Yes, CO2 should be warming, but if its effect is hard to detect and other factors can halt, or reverse that warming, then its unclear whet the resulting temperature wil actually be from doubling CO2.

That of course makes your claim non-scientific i.e. it's dogma. For example, consider Newton's theory of gravitation which was supported by 'irrefutable evidence' for about 200 years. Except that evidence was found to refute it. Hence Einsteins' theories which (as far as I know) have not yet been refuted but some day will. Unless GW does us all in before that. :-D

Don't know anything about it - not my area of expertise. So I neither support nor reject the view that CO2 is good for crop production. If I looked only at the links you provided I'd probably have to provisionally accept the view. However, I'd still recognise that I could be wrong and need to see if there is any conflicting evidence. I merely tried to point out that your statement that all scientists hold that view is incorrect. But we've been through this before - you make a sweeping claim that can be instantly refuted but still stick to the claim.

Suppose two bodies are traveling towards each other at velocities V1 and V2 respectively. What is their speed of approach? Newton's answer, V1+V2, is incorrect - for example suppose V1 is 0.9C and V2 is 0.95C (C = speed of light). That Newton's laws are approximately correct does make them correct. If you accept Einstein's theories you have to conclude that Newton was wrong i.e. his laws have been refuted. Of course that does not mean they are not extremely useful and, to all intents and purposes, can be regarded as 'true' in everyday life.

OK, so in fact at extremes Newtons laws fail, but in other cases they still hold valid. Ie two cars travelling towrds each other at 40 mph are approaching at 80 mph.

Knowledge of photosynthesis is not really what you were talking about. You were claiming that every scientist knows that CO2 is used in agriculture to boost crops. Now even though I might know about photosynthesis that does not allow me to draw the conclusion that increasing CO2 will boost plant growth. There is clearly a relation between CO2 levels and plant growth. But I don't know what the shape of that relation is. It could be linear (in which case you could boost crops by increasing CO2); it could logistic; it could be that it rises then falls. It could be that curves relating CO2 and growth are species specific. I don't know which is the case so I don't know that increasing CO2 will boost crops. It might do up to to some point for some species. On the other hand it might not. So I can know about photosynthesis and I can know that CO2 is required and yet still not know that increasing CO2 boosts crops. So your claims that (a) it's a known fact that CO2 is used to boost crop yields and (b) every scientist supports it is false.
