Extremes are evident, Unless you recognise that there will be no solutions ever. Co2 deniers have all their eggs in the same chook shed.
It's the most noticeable impact on earth to date. To just say that can not be the cause, is dumbing down any discussion at all.

Dear ant.

People would be a lot more inclined to believe the climate scientists if their prognostications and scary statements matched self evident reality.

What have we got so far?

A statement from Australia's own Climate Commissioner (who purchased a waterfront property) that "the dams will never fill again". Tell that to the residents of Brisbane. Then there are the rusting, white elephant desalination plants in Melbourne, Sydney and Brisbane.

Then there was the very first IPCC gabfest in Brussels which occurred during one of the worst snowstorms ever recorded in Europe. 300 million Americans are now sceptics after digging themselves out of 2 meter snowdrifts in New York.

Then there was the "ship of fools" who went to Antarctica to prove that the Antarctic was melting away, who got stuck in sea ice that did not even exist 100 years ago. Toss in Climategate, and the outright chicanery about "the Himalayan glaciers are disappearing", and you wonder why people are growing sceptical?

As I understand it, the science is in dispute. On one hand are the climate scientists with their ever more discredited computer models, and on the other, the geologists who have physical evidence that earth's atmosphere contained much higher levels of carbon dioxide in the past, yet was much colder than it is now.

I wonder what a real, competent scientist would have to say about all this. Probably has better things to do with his time then argue with fools.

Lego, in relation to Antarctica; I believe you will find that the sea ice has originated from the breakdown of glaciers. Winds are very strong and can quickly move ice bergs into an ice sheet. The ship was 2 ks from ice prior to being caught. Vessels are constantly being rescued in the Arctic area due to changing ice conditions.

Climate change is happening in the Polar areas where temperatures are higher than average. Glaciers and ice sheets are retreating.

The CO2 in the atmosphere can be identified Lego. Yes, there have been higher levels of CO2 in the atmosphere millions of years ago; but, in the past there has not been CO2 which is identifiable to the burning of fossil fuels.

At present, there is concern about glacier retreat in a number of South American countries as ice melt waters are their source of water supplies.

Thanks ant!

Anzac day is a sad day for me.

It is nice of you to provide a little laugh to brighten it up a bit.

Aussieboy – Good try but no matter how many facts you put before them, you can never get deniers such as Leo Lane, ChrisPer majulianutter or Peter Lang to change their views. Those views are little more than expressions of bigotry. You have probably noted that they fail to produce a shred of broadly accepted science, a single published, peer reviewed scientific paper in support of their views.

None of them will have read, let alone tried to understand the IPCC 5th Assessment Report, even though much of it, particularly Parts II and III are easily understood by non-scientists. None of them can produce evidence or even cogent argument showing the science is wrong. It is of course always possible that their opinions are correct and the findings of thousands of scientists are wrong – do you think?

Clearly, you recognize that continuing with business as usual will, apart from causing dangerous pollution, result in greater and eventually dangerous global warming. Australia should get a taste of this later this year with development of an El Nino event – except, because of global warming which has already occurred, the coming El Nino is likely to be a Super El Nino, producing the hottest summer on record.

Such things will not in any way change the views of deniers. They may sweat profusely in oppressive heat, watch TV footage of drought and bushfires, listen to reports of increasing losses caused. Will that change their views on global warming? Nope! However, the vast majority of the population will recognize these events for what they are – global warming – and demand governments everywhere take appropriate action.

There is always hope! Some people (named) clearly do not accept the science, even though the Abbott Government claims that it certainly does!
