I brought it in because I did my homework. There are concerns about warming from other sources.

Volcanic Aerosol Clouds And Gases Lead To Ozone Destruction
Volcanic eruptions destroy ozone and create 'mini-ozone holes', according to two new studies by researchers at the Universities of Cambridge and Oxford.
November 8, 2006
Craters in action on Hekla's southwest shoulder, Iceland.
The new research, spearheaded by Dr Genevieve Millard at the Department of Earth Sciences, University of Cambridge, discovered that volcanic gases released during eruptions accelerate reactions that lead to ozone destruction. The researchers found that even relatively small volcanic eruptions can destroy ozone and create localised 'holes' in the stratosphere. Previously, scientists had concentrated on the climatic effects of the tiny particles of volcanic sulphate created from the sulphur dioxide gas emitted during an eruption.
For the first time, analysing data from a 2000 eruption of the Hekla volcano, Iceland, the researchers discovered that volcanic gases may also lead to the formation of ice and nitric acid particles. This is a critical finding as these particles 'switch on' volcanic chorine gases, accelerating reactions that lead to ozone destruction.

How do you explain the sea ice growing on Antarctica?

Antarctic Sea Ice Is Increasing
Wednesday, May 03, 2006
Sure, sea ice is shrinking in the Arctic, but it is growing in the Antarctic. Sounds like natural fluctuations that balance out in the end.
Overall, it is true that sea ice extent in the Antarctic is increasing. Around the penninsula, where there is alot of warming, the ice is retreating. This is the area of the recent and dramatic Larsen B and Ross ice shelf break ups. But the rest of the continent has not shown any clear warming or cooling and sea ice has increased over the last decade or so.

Speaking of seeing the light, some scientist believe that Global Warming is caused by brighter sunlight.

Brighter sunlight to speed up climate change
Sunday April 2, 2006
Dr. Wild predicts brighter sunlght
The sun is getting brighter, increasing the pace of climate change and undermining claims that man alone is to blame, scientists have found.
A series of independent studies around the world show a significant rise in the amount of sunshine penetrating the atmosphere to be absorbed by the earth’s surface and turned into heat. The research will concern climate researchers who are already predicting a rapid rise in global temperatures due to man-made emissions of so-called greenhouse gases such as carbon dioxide.
"The enhanced warming we have seen since the 1990s along with phenomena such as the widespread melting of glaciers could well be due to this increased intensity of sunlight compounding the effect of greenhouse gases," said Professor Martin Wild of the Institute of Atmospheric and Climate Science in Zurich, Switzerland. They reverse a 30-year trend. Measurements of sunshine levels between 1960 and 1990 had shown a decrease in the amount of sunshine reaching the earth, a phenomenon known as global dimming.
Wild said: "Sunshine levels had been decreasing by two per cent a decade between 1960 and 1980 — a total decline of about six per cent. Now they are going up again. Perhaps this is why our Swiss glaciers are melting." Some showed a decline in sunshine since 1990, largely in fast-developing countries such as China and India.
"A widespread brightening has been observed since the 1980s.

There is little control over Global Dimming or Brighter Sunshine as Dr. Wild predicts. We have no control over volcanic activity either.

The climate changes of the long past all happened on geological scales (10's of thousands of years or more). Now it's within the lifespan of a human.

It's sounds like it's too late.

I am familiar with Gore but what has Bush done?

They are below sea level, that's why.

PS to any Gore-fans: His (partisan) political background makes him the worst person imaginable to mediatize this issue. For one thing, it's unacceptable that his movie is a commercial affair.

I am unsure what possible help Gore has contributed. He seems to focus on the drama, the spectacular and the illusion of Political Weather patterns called Climate Chaos and still blames Katrina on Bush.

Secondly, because of who is, the movie was primarily adopted by political parties all over the world instead of by the general public. And given the ultra short attention span of political parties, the movie will be a measure for nothing, in fact it will hurt the cause.

I wonder if we can save the bears.
