In the last two weeks, I have read articles in the newspaper which are indications of a global warming.
*Animals and plants are readapting and/or moving north. This may cause an extinction event unlike any seen in recorded history. Scientists are worried about the unevenness of the change. Ex. spring occurs earlier in some areas, not in others.
*Our atmosphere is divided into three parts-the troposphere, the tropopause, and the stratosphere. We live in the troposphere and planes fly in the stratosphere. Tropopause is like the filling between the two halves of a sandwich. Scientists are seeing the tropopause being pushed up as a result of the troposphere's expansion from warm air. Impact-more severe storms, It is the tropopause which sets a natural barrier to storms. (This is why thunder clouds have that anvil shape.)
*Weather conditions in Africa are occuring as predicted in computer simulations in a global warming scenario. The fear is that the African people will die from severe, massive famines and the lands will turn to deserts.
I am troubled by these events. However, I am grateful that I won't be alive in fifty years to reap the rewards of destroying our home. (We are in the very beginning of the global warming. We haven't even entered global warming yet.)

Blame CANADA!
Anyway - The whole African Famine has been happening since the early eighties. Civil Wars in most of those countries doesn't help.

Yes, the commercials for aiding those kids has been on since I was a kid, so it's been since the 70's.....
I have also read where this is a cycle that they have seen in the archeological studies, so a lot of the scientists aren't really that worried... Search google to see what is what, I, supposedly get off work in 25 minutes, so I haven't the time...
Mankind hasn't helped, I'd imagine, probably sped up the natural process with our pollution...

The last two decades more like...
Things are neither as bad as some say or as good as others say. Some scientist rave about how global warming will destroy all life on Earth and others about how it'll create a new golden age. Or that it won't happen.
I'm somewhat worried but, if all else fails I'll just emigrate to Mars. Posted by First of Two (Member # 16) on :
I've heard it said that this is the snowiest, wettest winter in several years, in PA.

Even if Global warming is not happening, (which I am not going to concede even though we are digging out from a foot of snow), this does not give free reign for us to start spewing pollution into the air at any given day of the week. Carbon Dioxide is not the only thing being thrown in the air from factories.

Unusual weather patterns, signs that things are changing.

Unusual? More like "back to normal."
I said "in several years," not "ever."
This year it's snowed like it did when I was a kid. Not no snow, and not one big giant 24" snow that never comes again. A bunch of decent, multi-inch (3"-5") snows.

If by You "PA" mean Prince Albert, Sask. Then yes, I think we've gotten the most snow this year than we have in the last several. But if you mean some other place with the initials "PA" then I have no idea where your talking about.
Anyways. I think it could stand to be a little warmer... Nature's tougher than we humans think, we may be smart, but we've only been here for a geological "blink of the eye". Who knows, maybe this is a completely natural trend, like the Ice Age. Nature will adapt. It's survived for the past 4+ billion years, Comets, Asteroids, and Ice Ages. No reason for it to go to hell in a handbasket now.

Regardless of Global Warming being true or not it really doesn't matter much. Now I'm not saying to go out and start dumping pollution, but that there shouldn't be as much panic about it. There are two different outcomes to all of this.
Non Global Warming(ie. We've had no effect)
The world continues to heat up for the next few centuries/thousand years. This is due to the earth still coming out of the latest Ice Age. After that time the temprature will begin to drop and drop fast. Given a century or two the earth will be covered in a nice frosty glow and humanity will have to scrape the ice off of its windows.
Global Warming(ie. We done screwed up)
The temprature continues to increase due to the build up of greenhouse gases. This in turn causes the polar icecaps to melt. This influx of water raises sea level and suddenly current beach front property isn't worth as much as it used to be. The raising of the sea level isn't the only effect this new very cold water has on the oceans. This new water will form giant underwater rivers. These rivers will flow towards the equator. Not only will this change the water cycles in the oceans but it will also begin to cool them. As the oceans cool so does the planet. After a few centuries the temprature goes down and humanity has to scrape the ice off of its windows.
Amazing how two different events can bring on the same result. Feel free to agree/disagree/cuss me out.

I hear the newest issue of Nature is going to report on how the hydroxyl levels in the atmosphere are not only higher than originally thought, but are actually also on the rise.
(Hydroxyl, I am told, is a major atmospheric "scrubber" of pollutants - it bonds to things like carbon monoxide and removes it from the atmosphere, which is one of the ways places can go from smog-laden to clear and pleasant overnight, some days.)
