For the FACE results, demonstrate that they will not be carried over to the actual environment.
Wrong. The FACE experiments got a 16% increase in yield. Farmers have ben using CO2 enrichment, recomended as 1000 PPM by at least one government, to increase crop yields for decades.

Also demonstrate that a 1 degree rise in temperature will not remove an equal or greater offsetting amount of crops from production.
Due only to temperature? Easy, farmers have been using greenhouses to grow plants for centuries.

Now I don't think you can demonstrate these effects
Just did.

Just think of the number of drugs that have been tested, both in labs and clinical trials, that have either proved ineffective or produced unexpected side effects e.g. Thalidomide.
If it had been tested for as long as Farmers have been using greenhouses and CO2 enrichment they would have come across its side effects. Like I said, Farmers have been using greenhouses and CO2 enrichment for a vey long time to increase crop yields. Those are the facts. Proved, empirical, known. :) Sure, you are going to say that in the 'real world', which is according to you is somehow different to the thousands of square kilometers of greenhouses used globally things will be different. But do you have any kind of evidence that that is so?
