This is the title of a show tonight on the history channel, 7-9 CST, about how sudden cold snaps impact civilization.

Maybe (maybe not) there will be information here that will support some of the various positions we have articulated here about global warming - or not.

Just a heads up for those interested.

The History Channel? I suppose that is will be sandwiched between shows about ghost hunters and UFOs?

don't forget something about Hitler as well!

No Kidding! What ever happened to showing history and not just speculative conspiracy crap. I used to love the History Channel, but now there is very little actual history talked about.

all i know is, after our last little "cold snap", i still cant get my car out of the lot

Well, if that picture doesn't prove global warming, Santa Claus doesn't vote a straight ticket.

UFOs and ghosthunters would seem to belong on a different channel, but Hitler? Sounds like just the place to hear about the Hitler years.

To the best of my knowledge, Hitler had nothing to do with global warming, but UFOs might be a different story. Especially if they are Republican UFOs.

Anyway, it is stilll America, if you choose to not view it I will not report you.

I just got though watching it You who didn't really missed something.

There was an era of warming called the Medieval Warm Period that ran from about 900 AD to about 1300 AD. Temperatures 4 to 8 degrees warmer then than before.

From about 1300 to about 1850 was the Little Ice Age - temps about 4 degrees cooler than now, but with a lot of variation. Different theories on triggers.

Both the onset and end occurred over about a decade each.

Most of the show was on societal changes and historical events that were influenced by the cold. Greenland, the French Revolution, American expansion, Napoleon, farming techniques, changes in crops, etc.

It ends with some projections, one of which is that global warming could trigger a new Ice Age (in the same way the Medieval Warm period may have triggered the Little Ice Age), leading to worldwide fighting over increasing scarce and valuable food, water, and energy resources, eventually possibly leading to nuclear war.

This is a worst case scenario, projected at a 1-2% probabilitiy. More research and scholarly discussion is called for.

Has anyone watched an Inconvient Truth? Rented it last night. I won't post the details but it was rather convincing.

I actually tuned if for about a half an hour, but I couldn't sit around and watch the whole thing.

I have read about the little ice age in the past, so I really didn't hear anything new, but I didn't stick around to listen to the conclusions.

Quote:More research and scholarly discussion is called for.

Hear, hear.

The Little Ice Age that ended in 1850 lingered for decades. I spent a lot of time researching the American Civil War and it is amazing how bitterly cold the winter campaigns were. The troops on both sides during the battle of Fredricksburg VA got to enjoy a show of the Aurora Borealis. Now you rarely see that unless in the northern part of the U.S. Canada or Alaska.
I lived in Alaska for 4years and never got over how amazing a show the aurora borealis was in the winter time.

I think the Northern Lights are do to the magnetosphere. It really has nothing to do with how cold it is. If the sun has a storm and emits strong electromagnetic waves you'll have a larger light show.

Shorebuc-

My great great grandfather served in the Northern Army and died from exposure. I have the death certificate at home. His unit died from being too cold. I believe it was in March too. I think Kentucky. I couldn't even imagine that. You would think they would have at least of had tents.

Blame Lincoln for sending the men into the field with poor equipment. Damn Republicans.

You have a good sense of humor Owl..... I just couldn't of imagined living at that time. The battlefield wounds that caused gangrene. Back in those times you just sawed off the arm or leg. Brutal times.

This is true. Its all the charged particles from the "solar wind" being displayed as it comes through the atmosphere. It occurs only at the poles because of the way our magnetic fields are aligned. If you have ever read about pole shifts, when one of those occurs the northern lights would be viewable all over the world, and to a much greater degree. The skies would be absolutely lit up for probably hundreds of years. Of course, during that time we would be much more susceptible to cancers, and the atmosphere would not be able to protect much at all.

You can learn a couple of things hanging out with me NIU.

I understand about the electromagnetic waves and the magnetosphere, I just never heard of the Northern Lights being seen so far south. A Civil War artist John Paul Strain has a beautiful work of the Battle of Fredricksburg and the Northern Lights. When I mentioned that battle I was talking more about the brutally cold conditions and ice flows in the Rappahanock which you dont see too often now a days.

My dad since he has retired from the Air Force has been researching our ancestors and the Civil War. So far he has tracked down just shy of 200 that fought in the Army of Northern Virginia. He has also tracked down some letters and diaries that are very interesting to read. The suffering that both sides went through with cold winters, hot summers, poor supplies, malnutriiton and disease is just hard to even comprehend.

3 or 4 years ago, the Norther Lights were visible in eastern North Carolina.

Here is a good little write up on the Northern Lights and what causes them.

Did you know "gullible" isn't in the English dictionary!

I'm not sure of the specific circumstances, but some rivers don't freeze like they used to because of dams on many rivers now. Rivers that once would slow to trickle, now have more consistent conditions all year.
