i think it's happening. I mean, look at the ice caps. Shrinking. Yeah it probably happened a LONG time ago but simple science proves it: warm air melts ice so the earth must be warmer if all this ice is melting. I don't have anything to back that up but if you took science class in 5th grade you would know about how ice melts. 
^wrong thread i'm guessing?^ lol
i think its happening. of cousrse the ice caps are going to melt, over the life of earth there has been a cycle of ice ages. we have just ended the last ice age, only 10000 yrs ago. the ice is just taking its time dissapearing. the more dense ice melts slower, and this dense ice it what remains during the summer. it is hard for glaciers to advance because the ice that freezes in the winter isn't as dense as the stuff that's been there for thousands of years, thus it melts fast, then all you have is the old stuff left halfway through summer, and that starts to melt. (don't trust me 100% on this, this is my theory. i've spent all my life in canada and know what melts slower and what melts faster. in fact the ice on our lake didn't totally melt until mid may, snow was all gone end of april, beginning of may.)
but after watching al gores inconvenient truth video, you realize how bad it is. it shows information about the atmosphere from before the last ice age, and how it has changed since then, and TONS of other info. (i just can't remember it off the top of my head). unfortunately the truth is, is that global warming is happening, whether we like it or not.

I'm thinkin' that's spam.....

Global Warming
The bigger question if if global warming is occurring, are humans responsible for it?
First, I'm not convinced that global warming is occurring. It was pretty darn cold here in America's Heartland this winter and until this week, we had very few days above the 70's. I have listened to so many arguments both ways that I don't know what to believe. Both sides make convincing arguments. It all depends on when you start tracking to global warming. I've always heard that figures lie and liars figure. Who to believe???
If global warming exists, I don't believe it is man-made. I think that it is all part of a cyclic thing that happens to the Earth. We've only really been accurately measuring and recording temperatures for 150 years or so (based on a presentation I saw). How can you judge millions of years of cyclic patterns off of that small a sample? How much extra energy does the Sun have to put out to make the Earth warmer? Wind and water currents can change. We measure those things now, but we didn't years ago. Can we really know what has changed? What do I know? I am certainly not a scientist!
That being said... Why NOT clean up our act. What can it hurt to develop some clean energy alternatives and reduce our carbon output? The world is becoming a crowded place and I can't stand messy crowded places. So, regardless of whether it helps with climate change, I do my part to reduce, reuse and recycle. AND I bike to work! That's more for me and my sanity than for the World but we can keep that between us.

i have a good friend who lives on cape cod.she said that it hasnt gotten over 70 degrees yet this year.mostly mid to high 60's!what's up with that? and i'm with Wazniak!!!might as well post a friken brosure!!!! i smell a comission!..lol..ride on
I dont think its a fact. Obviously, the earth is changing, as it always has. I think we have become so fascinated by "data" we have to come to some assumption and that is the one we somehow came to. I think the atmosphere has changed b/c of cars, people, cities, pollution, etc but global warming, i am not sold on it.

Of course its warming, it is summer and it is 96 friggin degrees outside right now.
Has anyone noticed that the suns capacity to burn your skin seems to have increased over the years? Has the radiation type filtered by the atmosphere changed, I haven't seen many charts about that
"Jun 27, 2008 ... For the first time in modern history, the North Pole may be iceless this summer." Poor Santa!

Global Warming? It was 56 degrees F in Lansing, Kansas this morning. It is currently 76 degrees at noon. These numbers are significantly lower than they are usually.
This raises one overriding question...
What the Hell am I doing in the office on a beautiful day like today?

Wouldn't the pollution concentration increases cause atmospheric changes that would cause cloud dispersion pattern differences over time? Has anyone studied that?

I believe we have an effect on the earth there are a bunch of us and to say we are not affecting the Earth is crazy. I think we are affecting the earth in ways more damaging than the global warming people are claiming. We are stripping the natural resources and most are not renewable.
The earth has cycles as most have said. During the Medieval Warming Period the earth was warmer than it is now. At that time the population was only a small fraction of what it is now and the world was not industrial. They were not putting pollution into the air. The global warming folks claim the pollution we put in the air is the main cause of the problem. Funny how the temperatures have been dropping since 98. So now we are in a global cooling stage. The global warming people figured now that there is some scientific proof to counteract what they say they have changed the wording to "Climate change". They have all gotten quiet about the Global warming and cooling. the scientific debate is over because each side has has their own proof and models to prove their point. Now it is being left up to the politicians and economists to determine how they are going to spin the issue to help them achieve their goals.
The "Global Warming" group uses computer models based on scientific studies. The accuracy of computer models that predict climate change over the coming decades has been the subject of debate among politicians, environmentalists and even scientists. A new study shows that current climate models are quite accurate and can be valuable tools for those seeking solutions on reversing global warming trends. Most of these models project a global warming trend that amounts to about 7 degrees Fahrenheit over the next 100 years.
But then there are those who bring froward some information regarding the accuracy of the models.
Achim Stossel of the Department of Oceanography at Texas A&M University, advises that "while numerical models have improved considerably over the last two decades, seemingly minor processes like the snow-to-ice conversion still need to be better incorporated in models as they can have a significant impact on the results and therefore on climate predictions." Whoa now wait a minute, from what I gather he is saying that they are not giving snow to ice conversion the proper amount of consideration. If you don't include ice cubes when you figure out how something is going to react then how can you determine how fast your ice tea is going to get warm. They are doing the same they don't have the ice weighted properly in the models to see how it will play a role in the warming. Maybe the ice would show that the earth is regulating itself and we will not see the 7 degree rise in global temperatures over the next 100 years.
A scientist saw we were getting warm. Does some research and publishes a study a bunch more study it and all see we are warming.Then by the time they got everyone fired up it started to cool. But in order to profit from it they had to say it would be a catastrophe so we would all freak out and run around screaming the sky is falling. Allow the government to throw our tax money at the scientists. Allow the politicians to use scare tactics to get people scared, who will then respond with emotion instead of knowledge thereby supporting the politician who most supports their emotion.
Here are some studies that show the climate is cyclical and has been warm before, when man didn't have a big affect on the climate. I say yes the climate is changing and it is cyclical. Should we worry about the world imploding? No. Should we do our bests to be good stewards to the earth so that it is not a stripped down wasteland for our children and grandchildren? Yes. But when being a good steward you need to use your brain and think logically don't allow emotion (anger, fear, helplessness) to cloud your judgment.
