More whining...

One of the latest global warming claims is that the weather will just be more unpredictable. Sometimes it will be hot, and sometimes it will be cold, and sometimes it will be just right. Since that pretty much sounds like any other description of the weather for the last 10,000 years, it makes global warming pretty hard to prove or disprove. There is another theory that says global warming will cause the next ice-age (or a mini-ice-age). Supposedly, we had one of those in the early-mid 1800's. I'm not sure what was supposed to have caused that one, though, since they can't say it was increased carbon-monoxide in the atmosphere. Another theory blames excess methane (bad cow!). Actually, methane can be released from swamps, deep-sea deposits, and from thawed permafrost (northern tundra that gets too warm). It could come from anything, in other words, and nobody seems to know how to tell what will happen, when it will happen, or even if it will happen. Some people think the oceans will just absorb the extra gases; some people believe the oceans will release extra gases. Anyway, the bad news is that the last mini-ice-age seems to have come on kind of sudden-like. They went from the warmest summers on record in Europe, to the coldest in less than 10 years. They think it had something to do with the "deep-sea ocean conveyor" that distributes salty, less-dense, warm water from the equator to the less-salty, dense, cold arctic water. Anyway, at some point, the temperature difference between the equator and the northern seas becomes small enough (warming of the polar ice-caps) that the "conveyor" shuts down. Once the conveyor shuts down, Europe freezes over in a relatively short period of time because the warm water that normally flows along the coast is cut off. The wind that was formerly warmed by the warm water in the ocean is now cooled by the cold water in the ocean. Then the Thames river freezes over (like it did in about 1830). Viola, mini-ice-age.
Have you thought about getting a wood stove? I know they are messy, and chopping wood is a serious pain in the ass, but it would beat freezing to death if it did turn off really cold for a while. I am pretty sure you remember getting snowed in when we lived in that house west of Kingfisher back in 1981-82. The snow wasn't even that deep, it was just that it drifted over the driveway so bad we couldn't get out. It would be pretty easy for that to happen to all the roads in your part of the state.
