Part 1: The geological time line of our planet can be broken down into warm and cold period. Ice ages can be broken down in to two main groups Glacial and interglacial periods. We are currently in a interglacial period.
There are three main types of evidence for global warming. Geological evidence for ice ages comes in various forms, including rock scouring and scratching, glacial moraines, drumlins, valley cutting, and the deposition of till or tillites and glacial erratics. Chemical evidence mainly consists of variations in the ratios of isotopes in fossils present in sediments and sedimentary rocks, ocean sediment cores, and for the most recent glacial periods, ice cores. Paleontological evidence consists of changes in the geographical distribution of fossils.
There are four ice ages that are believed to have happened in our planets life times. The first ice ages happened over 2.7 billion years ago. The next ice age started approximately 850 million years ago and ended about 630 million years ago. Their was a minor ice age approximately 430 billion years ago. The last ice age, which we are technically still in started 40 million years ago. About 10 thousand years ago we went from a glacial period to an interglacial period in our current ice age.
So the world jumps between extremes Ice ages and times with no ice at all. We are in an interglacial period that can have server temp changes either way. Is man to blame for global warming? No did we have an effect on it? Maybe. Should we worry about it? We could have the temperature rise or drop at any given time no matter what we do.
Written history tells us that in the 11th to the 13th century their was a medieval warming with temperatures 1 to 3 degrees F. warmer than today. Aroundish/before the arrival of the Black Death Europe went into what is known as the “little ice age”! History also records an earlier Roman warming, it too followed by a mini-ice age.(looking for more proof of this) These trends match what is going on now!

[Reverend Blair]

The medieval warming period, little ice age, Roman warming, and the subsequent cool period are problematic though. They don't seem to have been global and there is at least some evidence that points to cool period during the Dark Ages (following the Roman Warming) being caused by a major volcanic event.

It is also questionable whether we should be warming right now, or whether we should be in a cooling period. The Milankovich cycles...basically a wobble in the earth's orbit...point to us being at a time and place where we should be cooling, not warming.

So are we contributing to global warming? Fill a glass tube with CO2 and another with oxygen and the one with the CO2 will be hotter. We've known that for more than 100 years.

Do the same experiment, but this time match the PPM of gases in our atmosphere pre-industrial revolution, circa 1960, and today, and you'll see the temperature go up with the changing atmosphere.

The earth is warming up and we are the major cause.

No matter how in-depth you delve into history or how much technical language you use it will not change the fact that the industrial age, which we are still in, as increased pollution in our atmosphere to a point that it is killing not only our planet let us as well. And this is the reason we are warming up, the pollution. It has put a blanket over us that is making us warmer. It's time we kicked that blanket off!

[ACCER]

And 25-30 years ago they were claiming that we were heading into another ice age and that the blanket of pollution that you speak of was blocking out the sun and making the planet cooler. I wonder what the "big crisis" to the planet will be next.....

I also wonder when they are going to blame humans for the death of the dinosaurs.....

[Green-Moo]

Whether the current situation is a mirror of the past, I don't think anyone can deny that we, humans, are doing indescribable damage to our environment and at a much faster rate than even before.

[Roguegal]

The blanket that I spoke about did close our planet to start cooling down. But because that blanket has such a high concentration of CO2 in it now it is causing the planet to warm up instead. I also agree with Green-Moo that it is us humans that are damaging the environment. Between the massive amounts of CO2 that we produce and all the "trash" that we make, our planet is going down the tubes. Unfortunately, it is the only planet that we can. If we kill it, we kill ourselves and all future generations. There has to be a happy middle ground somewhere. Otherwise, our children and grandchildren will not have any place to live.

I cannot understand how there still can be people that fail to understand what is happening with global warming; stranger still, the people who are proud to NOT understand. I know that there are going to be the ignorant among us always, but it's my grandchildren and yours who will be poisoned and impoverished because of them.

[ACCER]

Molly,
What many of us would like is some hard scientific facts that are not gathered by some group with a hidden agenda. Real data off of real research. Not some emotional horn blowing that is proven later to be agenda driven, fake and meaningless. I'm at an age where I have seen so much media driven BS over the years that I barely believe the nightly news when they tell me who won the election....let alone anything else.

[ACCER]

Rog,
I'll see if I can dig up a few of those old books. Maybe you would be able to locate them in libraries or a used book store where they use the exact same information to push proof of global cooling that is now used to push global warming, including CO2 levels. It's the same song.....just a different band playing it.

Did Anyone see the Sarcasm? Did any one see my playing Devils Addvocit? Did any beilive that i beilive this bull shit? As if im brainwashed?
