    You can measure temp by what grew. One study did involve Utah. Scientists studied packrat middens and found pollen/seeds and other artifacts from trees and plants that now grow mostly in the alpine zone. So it was colder then. Now plants from warmer climates seem to be migrating north.

    We will either have to bioengineer our food crops or find others. Corn and wheat require a certain growing season. Should we only be able to grow them in the far north, the land area is not there.

    You can see what too thick a cloud layer can do. The probes sent to Venus showed that. Too light an atmosphere and you have Mars.

    One article I saw said that climate change would cause humans to evolve differently.

    We don't have a thermometer on the sun, yet we have a pretty good idea how hot it is. Same for many other places, like distant stars, that we have never even been within a billion light years of. To say that there were know thermometers then, therefor there is no way of figureing it out is ignorant. We have the ability NOW to measure what the climate was THEN. In the ice caps are preserved extremely detailed records of atmospheric conditions. As well as other methods to determine past climate (tree rings, fossilized pollin, biological and inorganic marine sediments...). There are many differant ways to determine the past climate. In fact, for most of the earth's history, scientists have concluded that the earth's temperature's were on average 8-15 degrees c warmer than they are today. The thing is, for most of the earth's history, we were not part of it. Could the earth sustain us if it were to go back to its "norm"? That is the debate. I say, the earth isn't sustaining us now.

    Perhaps what is happening with the ice is simply natural and man has nothing to do with it.

    Wether it is natural or not, really means nothing. All that matters is the effect it will have.

    I have been trying to see it that way, too.
