CO2 is a poison to humans and a waste product. Increase CO2 causes increased respiration until it becomes to high then it becomes a narcotic and you stop breathing. This can happen with pretty very small increases in blood CO2 (in chronic disease), I have witnessed this many times.
I don't know how to answer you Joe, greenhouse gasses are not visible. How does our atmosphere and magnetosphere protect us from solar radiation? We can't see it so it clearly can have no effect. Yet it does. A greenhouse traps radiation to make it warmer than the outside temperature it has nothing to do with CO2, that remains the same in and out of the greenhouse. Greenhouse gases have always referred to gases that hinder the infrared radiation from radiating back into space. These gases absorb the long wave lengths, I would be interested in a source that refutes that. It was taught in my Biology classes. BTW, The perceived economics are not a scientific argument. Al Gore has not made hundreds of millions of dollars on this. The Economic motive is much bigger for the oil and gas industry, who ironically would likely not see a big drop in demand, just not big increases. It is a mystery to me why the claim is made that CO2 causes warming. It is
an odorless, colorless gas. How could it hinder light radiating back into space? And do any studies support that idea? I suspect that CO2 is a greenhouse gas in the sense that plants thrive on CO2, as they would in a greenhouse. We know plants absorb CO2 and release oxygen. So what's so bad about CO2? -- Joe

We had different first grade science studies. My first grade science taught me that there are probably "millions" of galaxies that exist in the universe. There might even be a solar system in one of them that might be capable of supporting life. Further, there were nine planets in the solar system.
My father was taught in his first grade class that the universe is stagnant and not expanding or shrinking.
Which first grade science exactly are you referring to?

My understanding is they are seeing events in Antarctica that have not occured in several hundreds of thousands of years. IE, it is beyond the natural cycle. Local cooling and warming are not inconsistent with global warming, we are in the early stages and it is much more apparent in the upper atmosphere. Where greenhouse gasses will have the greatest effect. A few frauds do not change this.
That man's activity has increased CO2 levels seems certain, and again it is grade school science that this hinders natural energy from being radiated back into space.
It is a given that many have exaggerated, both by the deniers and supporters. Still more science supports it than denys it.
The earth has always had periods of warming and cooling, and it is my
understanding that over the last 160,000 years the earth has mainly been under the control of ice except for two warming periods known as the Eemian Interglacial and the Present Interglacial. These larger cycles can be broken into periods of short cycles lasting around 400 years and then broken down to 40 years period. We see this in recent history with the Medieval Warming period and the Little Ice Age (400 year cycle example). Our current broad cycle, the Present Interglacial is about 18000 years into it so we can estimate that at sometime in the next 2000 years our planet should cool and possibly enter a new Ice Age.
So in my own opinion I believe we are seeing a period of warming and that at some point we will see (or our descendants will see) a cooling period. Bottom line, the climate of this planet changes for a variety of reasons (humans being a very small percentage of that) and we need to be aware that of its own accord it changes and we should be ready to adapt to those changes.
I like this quote the best: "Since the climate has always been changing and will likely continue of its own accord to change in the future, instead of crippling the U.S. economy in order to achieve small reductions in global warming effects due to manmade additions to atmospheric carbon dioxide, our resources may be better spent making preparations to adapt to global cooling and global warming, and the inevitable consequences of fluctuating ocean levels, temperatures, and precipitation that accompany climatic change."

I'm just guessing but is it possible that it may be melting because
of
some kind of cycle?

Finally, the article that proves it is all a hoax. I guess the question remains why is the ice melting?
My understanding from past list administrator statements is that this kind
of post is "okay" here.

Hacked emails from the Climatic Research Unit (Britain's
University of
East Anglia) appear to implicate leading climatologists with scientific fraud.
