CJ, > Change the climate and you change what can be grown.

The climate has been changing for the past millions of years, even before man learned how to burn things (and release CO2 in the process).

The climate will continue to change, sometimes drastically.

I understand perfectly what is behind the claims. Hand-wringing.

>>> But what about wheat and corn?

There was a time, a few thousand years ago, when there was no corn at all, and in fact its predecessor (basically, a weed grown in Central/South America) was evolved to be the corn now grown in N. America.

If the climate changes so radically that corn isn't grown somewhere, it will grow somewhere else. Besides, just as native Americans caused the evolution of Teosinte into corn, I'm certain we'll be able to adapt whatever does grow to our needs.

The planet is resilient. A little more CO2 than usual isn't going to hurt it. Who knows, it may bring about some positive changes we weren't counting on.

Don't act like it is some kind of ultra fragile ecosystem. This is the kind of crap you get from watching too much PBS.
