We need to build a huge wall on the northern border to keep that cold air in Canada where it belongs!

That's actually one of the theories as to what might happen if the oceans continue to warm--not a full fledged ice age but colder continents. What's been happening is that warmer air (and water) is pushing further up into the Arctic and that is displacing the cold pockets of air southward.

As far as what creates ice ages, I don't think that has been quite figured out totally but I know that it's likely to due with the obliquity of the eartha nd a few other factors. In that sense, yes, it is a cycle. It's where on the position of that cycle we're at and whether that coincides as to what is happening now. The things that scientists do know about the grand cycles of the earth do not offer any explanation as to what is occurring presently. That's one of the reasons why so many scientists do not question anthropogenic climate change.
I think part of the problem is that, early on in the examination of these issues back in the 70's, there was a lot less data than we have now. Additionally, we have a ton more of processing power for all that data, which also wasn't there in the 70's. The more data that the scientists collect and process, the more refined the what ifs are going to become. In that light, you bet that opinions of what might happen are going to shift over time as more information comes in. That's the way it works for anybody. Does your opinion necessarily stay the same when you learn more information on the subject? Maybe, maybe not--depending on that new information.

Yet there are still people who say that the world is getting warmer. Maybe it is...it's called Climate Change and it really has nothing to do with politics, or mankind. It is just the way it is...nature. Can't legislate that.

Actually, the same weather patterns were prevalent in the late '70s when everyone thought we were entering the next Ice Age.

I was reading a study awhile go by some I think Japanese scientist that think the ice ages are cause by the solar systems travel around the galaxy and that it was getting to be time for another. I'll post a link if I can find it again.
