I'm not making the case that climate change is happening here and now, BUT even a few degrees difference, plus or minus, can result in massive crop failures and livestock deaths. Geological data over thousands of years shows that the climate does indeed change.... it's the natural order of things on Earth. Climate purists seem to think that there is some kind of "ideal climate" that we must somehow impose, even though we don't have the technology to do that.

We are currently experiencing droughts in the western and mid-western states, an it's probably a long-term trend, AND probably due to increased solar output by the sun. We are entering a new climate pattern, most likely, but there's not a damned thing we can do about it.

No amount of CO2 reductions, "fossil fuel" consumption, or any other "Green" efforts will make a dent in what is coming. There are forces at work -- solar, a diminishing Earth magnetic field, methane emerging from deep in the Earth's crust, etc. -- that we have no way of controlling.

The best we can do is prepare for long-term shortages.
