"I'm not convinced that agriculture will play a role on changing global warming. It will definitely be affected by global warming because if we see just a few degrees change in average temperatures that will make a huge influence on how well our plants grow. And so, we have to be prepared for that if we can't tide that, or change the trend towards warmer temperatures throughout the globe. Some plants will do better. Some plants will do much worse. We have a lot of cool season crops like wheat, for example. Look at when the wheat is actively growing. It's in the spring and then in the fall. It doesn't handle the heat very well. So, if temperatures, higher temperatures occur just in the summer months, it won't influence wheat very much. But it could influence corn and soybeans, for example – if the high temperatures also translate to less rainfall, for example. Corn, you know, as good a crop as it is, it's amazingly vulnerable during pollination. So, if the corn crop in Nebraska is pollinating over a two-week period, and for some reason temperatures were over 100 every day, we would see a pretty significant effect on grain yields mainly because, even if there was plenty of water available, those high temperatures kill pollen. If you don't have pollen, you don't have seed set. I guess I can't generalize. It's always going to depend on how the weather pattern emerges. So, one thing we can do pretty easily is measure changes in these greenhouse gases. We know they're going up. Predicting how that's going to translate to weather pattern changes is much more difficult."
