These scientists are not idiots (like the general public). They are aware of the weaknesses and strengths of the underlying data. That’s why they’re called professionals.
Your statement does nothing to answer the question as to where the data he used originated. I’m sure you’ll be distressed to discover that a great deal of the data proving global warming exists is obtained from the ground based stations. Guess the professionals didn’t get the word. As for your contention that the general public are idiots, I won’t dispute that since the majority accept the global warming claims of Al Gore et al at face value.
That only means they get paid for doing whatever they do. It doesn't say anything about their competence, honesty, or impartiality.
Your unquestioning faith in the objectivity of the scientific community is quite touching.
Not idiots? Most of them are. They are just liberal idiots that couldn’t find a real job so stayed in academia because of job security.
All they are doing now is keeping their grant money flowing. A lot of these are the same idiots that were drumming global cooling and the next ice age to us in the 1970’s.
