Scientists are still observing the evidence, developing hypotheses, etc causing them to have disagreements over global warming. If you choose to sit on the side of the scientists who belive in global warming even though data is still being collected, good for you. But, since a final agreement has not been made, I hardly think you have the right to talk down to those who do not believe it
These three sentences demonstrate a fundamental lack in your understanding of the scientific method.
Your comments are also factually incorrect.
Science never stops when an agreement has been made - it's a continuous process with progress in understanding as a goal that will never result in 'final agreement' in the way you allude to.
Let me fill in your colander of a response with some facts:
The most recent United Nations sponsored report on climate change was issued in February 2007 by the Intergovernmental Panel on Climate Change. The report told us that the broadest consensus of climate experts in the world drawing on some tens of thousands of peer reviewed scientific studies, concluded that the reality of global warming is 'unequivocal' and that there is strong evidence that this increase in global temperature since 1950 is directly attributable to greenhouse gas emissions from human activity.
The IPCC also concluded that without a massive reduction in human-created CO2 emmissions climate change may bring "abrupt or irreversible" effects on air, oceans, glaciers, land, coastlines and species. IPCC Chairman Rajendra Pachauri told reporters "if there's no action before 2012, thats too late. What we do in the next two or three years will determine our future. This is the defining moment."
If you want more consensus then research Sigma Xi "Confronting Climate Change", or you could put your head back in the sand.
