With this issue, what I've always tried to understand is why there's an opposition to the idea of the climate changing. Is it opposition to the changes due to HUMAN factors, or natural?
The climate always changes. I am not so arrogant as to presume humans are the cause.
Remember al gore stated 5 years ago, there would be no polar ice caps!
Does everyone believe what Al Gore says?
I do think humans have contributed to some of the changes, but I don't think it's a good enough reason to start pushing through all kinds of legislation. Human behavior is difficult to change and while there are options to reduce waste and CO2 emissions, most people won't because it would interfere with how human life has existed for some time. Unfortunately, with the changing climate I don't think humans are going to do well with adapting in spite of its necessity. Throughout human history, we haven't had to deal with the changes happening in the short amount of time as they are occurring today.
The polar ice caps are a good example. There are studies on the caps which reveal the amount of gases they hold, particularly CO2. If the climate is changing at a rate where they are melting much faster than projected, those gases are going to be released into the atmosphere. My question is, are we going to be able to adapt to the changes which arise? We have a tendency to insist the economy can't be hampered due to environmental factors but I think we are going to see a change in that within the next 50-100 years.
CO2 is not causing the earth to warm. The medieval Warming Period was warmer then than now.
Did humans cause it?
Is that certain? I understand there were a variety of factors, such as ocean current, solar radiation, and less volcanic activity. If CO2 isn't a contributing factor, what is?
There isn't. Obviously climates change or many of us would still be under thick sheets of ice.
The question is whether or not there is a human factor. An opposition to natural changes would be a bit of a waste of time.
Trust me, some people really do behave as if they are still under thick sheets of ice.
Why is it controversial to suggest if there were human factors? We've been manipulating the environment for thousands of years and for the past 200 years introduced technology to shape it more. Is it unreasonable to suggest what we have done made a contribution?

Water vapor.
CO2 levels increase as temperature increases. CO2 does not cause the earth to heat.
Common fallacy.
Sunspot activity also contributes. Right now sunspot activity is at an all time low.
