That's your definition of AGW? OK.
Everyone seems to kinda have their own. Which is one reason we get inundated with these totally bogus claims that "97% of scientists believe in AGW."
Going from memory, one such "study" solicited responses from about 7,000 scientists. After the responses were received, they reduced the number they considered to only 77.
With respect to those 77 they looked at the answers to only two questions:
1. Do you believe that earth's temperatures have increased in the last 150 years? and
2. If so, do you believe that humans contributed in any significant way to the warming?
If the respondents said "yes" to both questions, then they were deemed to be supporters of AGW.
75 of the 77 did answer yes to both, so, then, there ya have it, eh?:
97% OF SCIENTISTS SUBSCRIBE TO THE AGW HYPOTHESIS!!
Of course this says nothing about their opinions concerning the multitude of labyrinthian claims proposed by the IPCC papers, etc.
