Global cooling

Over a very long period of time, shouldn't polar ice thickness be a random walk process anyway? So if you drilled deep enough into the ice, you'd find the depth where the process had not "walked" since the industrial age?

I don't think I'm following your use of the word "walk" here. I'm not sure what you mean.

I'm subscribing to the whole theory that our galaxy axis is tilting. This brings extremes on both sides of the weather spectrum, meaning it would get really hot in summer and really cold in winter plus extreme weather systems like increased hurricanes and other storms. We have just started to experience this in the past couple of years and apparently it is only going to get worse for the next couple.

Yep I think that's the problem. TOO.

I wonder if the spiral arm we inhabit is tilting at the same rate as the rest of the galaxy is? Or will we just collide with the LMC first?

So what would the explanation be as to why a shift to the earth cooling? And if it stays like this for a few years, you would bail on the whole thing right? Probably not ut, I'm sure many would...

I've read a lot of people who are smart enough to know better confuse climate and weather to support their own hypotheses regarding climatological changes.

I don't think we've had technology sensitive enough to collect pertinent, reliable data on climate for a long enough period of time to conclude anything regarding climate. Weather, sure. Climate, nope.


BTW, Al Gore has a really big house everybody.

It all has to do with hydrodynamic variations and the thermohaline circulation -- the meridional overturning circulation -- primarily in the north atlantic.

Global warming is not about global "warming" -- it's about climatary extremes, i.e. extreme hot, extreme cold, extreme precipitation, etc., all of which are influenced by the oceans' great heat capacities.

lol. Houses are one of the biggest polluters. Or so I hear.

Ya, I thought I just said that in my layman terms up above from what I heard a scientist say.

By the way a mini Ice Age would be a bad thing for economic future of the world.
The mini ice age of the middle ages (dark ages) was one of the contributing factors in the slowing of human development economic and otherwise.

That ice age was actually caused by excess ice in north america melting and draining into the north atlantic MOC, effectevely shutting it off.

This is the same reason scientists are freaking out about melting ice caps and greenland -- their efffect on the MOC up there.
