I have been doing some thinking and I was wondering what other gamers think. I have thought for a long time that the "o-zone layer" was something that does not exist. Global warming didn't make since either due to the fact that most places away from the equator still have cold winters. However, I could not attribute the so called global warming to much other than the magnetic field failing. Anyway, I was thinking the other day, when I turned on my air condition, about how it creates heat on the outside. This is true for anything we operate outside. Machinery, cars, air conditioning, body heat, etc...

As the earth's population grows, we expell more body heat and all of the others due to more people needing more things that create heat. Therefore, it makes since to me that we are mearly making the summer hotter. In the summer, we do more work creating more heat that makes the illusion of global warming. Whereas in the winter, business slows, air conditioners are turned shut down, and most people spend time inside. In reality, global warming wasn't even heard of until air conditioners and machinery were common everywhere.

My theory is that pollutants in no way effect our so called o-zone layer. It is actully us producing extra heat, heating the atmosphere.

Anyone?

I'm pretty sure that pollutants are the main contributer to global warming. Just look at the rapid acceleration of the degradation of the atmosphere since the industrial revolution.

Do you really think that human body heat is melting the polar ice caps?

No. Human body heat is higher than it would have been in previous years, but the main factors in my theory are the industries creating heat, not pollutants.

It's possible, but maybe it's simplifying the issue too much. Older fridges and air conditioners have slowly been phased out due the issue that you've suggested, so we know that it's a contributing factor.

Pollutants rise into the sky and during hot summers, when the sun's rays are really strong, there is more of an effect in urban, industrialized areas. That's why every summer here in Toronto, we have about a dozen smog warnings where we are advised to stay indoors due to the adverse effects of the sun/pollutant mixture.

I think that I veered slightly off topic, but what I'm trying to say is that, in my opinion, pollutants must have an effect, just like built up latent heat does.

You make a good point with the smog warnings. It seems to me that the pollutants in the atmosphere should be making it thicker, blocking the sun. That should create a cooling effect. Our ice ages have been created by natural pollutants blocking the sun, so why wouldn't our current pollutants have the same effect?

No, global warming is actually just a natural cycle of the Earth, it can be caused by many things, humans, not one of them. Although the alarmist love to create that illusion. However, this does not justify going out and purposely polluting in any form if you can help it. Heat from humans and whatnot is definitely not a contributing factor in that it would create such a minimal effect over the entire atmosphere.

The polar ice caps are not melting; polar ice levels are above average for the time we've been measuring it (only about 30 years, so not much history to draw on).  The Arctic has had declines in ice levels (but has actually increased over the last two years) while the Antarctic ice is at record highs.  But again, we are drawing on very little history to compare to.  You can easily make an argument that the Vikings grew grapes in Greenland around 1000-1100 AD so it must have been warmer there then than it was today. 

It's very difficult to accurately reconstruct climate records from the past to compare to the present, and even trends in the last 150 years show 0.6 degrees C of warming at most.  It's really an argument about the future - will more drastic warming occur with increases in CO2 levels?  Of course, these things are incredibly difficult to predict, and climate science is still in its infancy.

Anyway, this thread cries out for actually gathering information.  Just because it is cold somewhere in the winter does not discredit global warming, any more than one hot day in the summer makes it the gospel truth.  I suggest you read up on the evidence.

Try these sites:

Then decide for yourself (those sites are on the opposite sides of the debate, more or less).

From what I've learned, there has never been such an accelerated warming period as what we're experiencing now. If you look at the history of the earth through the idea of deep time, many of the warm periods of the past took many, many years to complete the cycle.

This is true, and it just strengthens my point, it is nothing that we can change, and there is no reason to get all bent out of shape for something that we cannot cure, something that will "cure" itself. Anyway, up until the mid 1800s there were no specific records, even now, our records are being skewed by bad placement of thermometers in the world (putting them over blacktop, or next to heat generating machinery).
