there is absoulutely no evidence whatsoever that global warming is man-made.
Absolutely none, eh?
I wonder why, in that case, the IPCC have stated that most of the observed increase in globally averaged temperatures since the mid-20th century is very likely (>90%) due to the observed increase in anthropogenic (human) greenhouse gas concentrations?
And that the probability that this is caused by natural climatic processes alone is less than 5%?
I wonder why over 30 national science academies have issued joint declarations confirming man-made global warming, and urging countries to reduce emissions of greenhouse gases?
I wonder why hundreds of countries have signed the Kyoto protocol?
I wonder why survey after survey of published papers and of direct polling of scientists shows that an overwhelming majority agree that man-made climate change is real?
We are talking here of the work involving
thousands of scientists, all peer-reviewed. We are talking here of organisations like the Royal Society saying ""There is strong evidence that the warming of the Earth over the last half-century has been caused largely by human activity, such as the burning of fossil fuels and changes in land use, including agriculture and deforestation." Of the American Association for the Advancement of Science saying "The scientific evidence is clear: global climate change caused by human activities is occurring now, and it is a growing threat to society."
I wonder why surveys have formed conclusions such as
"the relative climate expertise and scientific prominence of the researchers unconvinced of ACC (Anthropogenic Climate Change) are substantially below that of the convinced researchers."
and
"It seems that the debate on the authenticity of global warming and the role played by human activity is largely nonexistent among those who understand the nuances and scientific basis of long-term climate processes."
?
I wonder why not one scientific body of national or international standing now rejects the findings of human-induced effects on global warming?
Do you really think that all this is some fantastically, (and historically utterly unprecedentedly well) organised conspiracy by hundreds of countries and thousands of scientists to scare us all into using less oil before it runs out?
Does every individual scientist agree? No.
Is 100% of the evidence unequivocal and consistent? No.
Is every single scientific paper correct? No.
But "absolutely no evidence whatsoever that global warming is man-made"? Please don't insult our intelligence.
