Colder winter and cooler summer, the global warming theory sounds like junk. What do you think?

I look at climate change like a relationship with a teenager. You can have a discussion with any young pup and explain to them consequences of their actions, consequences of cause and effect, consequences of not investing in their future and thinking things through to logical solutions and end-states.

The reality is that changes are occurring yet our comfort zone has not been radically affected. Yep it is currently 22 degrees outside and I just got in from a walk around campus. Although my immediate comfort zone was temporarily effected, what's the big deal. It will get warmer, it will get colder, it will rain, it will snow. So what?

I watched a 60 minutes segment on water last night. We are taking money out of our "environmental savings accounts" and not putting anything back in. Water issues abound. Tell California to "fear not" it will rain again some day. Climate issues abound. Ice caps and glaciers are receding at alarming rates. Weather patterns are changing. Population growth continues, urbanization and industrialization as well and yet we just keep bantering back and forth on philosophical diatribes that in the end, serve no purpose other than obfuscating issues and the endless stalemate of stale discussions about necessary change.

What happens in our dialogue when all of a sudden we hit a non-refundable/non-renewable savings account and hit the breakeven point of negative returns because we are far too enamored with arguing that something needs to be changed. We really do need to think into the future, outside of our comfort zones and get past the rhetoric.

There is no question that the earth is warming. However, I have to ask, what ended the last ice age? The earth warmed and the ice cap receded. This with no factories, automobiles, and other man made influence. It seems to me that the smaller the ice fields, the more rapidly they should shrink. I think that the neanderthals are to blame for whole damn thing. How dare they have too many camp fires.

I have my suspicions that global warming is a myth. Research has been done, myths proven/disproven, and more and more theories are flooding the Introwebs every day. But, in my opinion, I feel that global warming is nothing but unnecessary fear pressed on the public.

I am all for taking care of the planet, however, I believe the global warming scare is over exaggerated.

There is too many conflicting reports to call global warming a crisis. Depending on what scientist you ask, and their agenda, will get you different results.

My personal, non-professional belief, based on what little I know is, global warming is a hoax. Another way the government tries to use whatever it can to control us.

The Earth's climate system is an enormously complex nonlinear dynamical system. Having worked on relatively small complex nonlinear dynamical systems (writing software for an automobile engine controller to regulate the idle speed, for example) I can state without hesitation that these things behave in ways that will blow your hat off (or whatever might indicate astonishment for you).

The study of complex nonlinear dynamical systems is somewhere between science and a black art, but there are some simple examples that can illustrate some principles.

Principle: Adding energy to a nonlinear dynamical system will tend to cause the peak-to-average ratio of at least one system parameter to increase. (In climate terms, it means that tripling the input of trapped solar energy is going to cause some things to become more extreme -- hotter summers some places, colder winters other places, five-mile-wide tornados...).

Simple illustration of this principle: A child on a swing.

You gently push the child forward, and she swings back. You push again, and she swings a bit farther. Note that her AVERAGE position is where she started: motionless at position zero. But by now her PEAK position may be quite a ways away from the stopped position.

Principle: nonlinear dynamical systems may exhibit sudden unexpected "phase" changes as the energy budget of the system changes.

Example: you continue to push the child on the swing until she eventually achieves such a height that the rope or chain on the swing loses tension and she actually does a bit of free fall before re-entering the normal swing regime. (When I was about six, it took me a while to figure out why things got jerky if swung too high.)

And that's a simple nonlinear dynamical system, consisting of swing set, child and adult pusher.

Perhaps it wasn't humans who dug up all that carbon and burned it for power and warmth, thereby tripling the relative concentration of a gas known to be opaque to a large part of the infrared spectrum, but there is demonstrably a lot more CO2 in the atmosphere now than there was 200 years ago.

This much is certain: you can't wish away the laws of Physics, and you can't BEGIN to predict what the global system will do as its solar energy intake continues to rise.

But it will make some cool movies, if there is anybody around to make them.

Climate change is already happening I don't understand why people don't see it. It is not normal to get up and it's 80 degrees then drops to 30 and snows on the same day or the other way around. People think global climate is going to change like in the movie 2012. Climate change is here and is changing our world already. Is like this..... People claim that theories are just theories but so is the theory of gravity and I'm 100% sure that everyone believes in that one.

oh didnt you know... didnt you Hear... they changed it... the name is now called climate Change...

Probably because many are too emotionally compromised to accept scientific facts.
