Farmers Assoc's and climate change

Have any major agricultural groups/associations, either farmers or ranchers, addressed climate change for their members?

You know, “Beef, it’s what’s for dinner” type outfits. I’m sure they’re not only promotional groups for their industries but give advice or forecast crops/prices.

Do they, since it seems likely they have a politically conservative make up, dismiss it out of hand? Or have they taken a real look at the facts and reached conclusions in either direction?

What about various university cooperative extension services?
