My response should not be construed as indicating that I believe that the majority of the scientific community "is never wrong". On the issue of climate change, I do believe that the majority viewpoint that the currently-observed warming trend, particularly the warming beginning in the 1980s, is strongly related to human activities.
You should read the lecture by Michael Crichton linked on post #3. It might help you to have doubts when you hear the words "the majority of the scientific community". Usually it is spouted when there is a political or sociological motive without facts or a proof to back it up. In other words - JUNK SCIENCE!
Many grants are issued for scientists to come up with results to match the granters desires. No real scientist would skew tests to achieve a desired conclusion. It appears that 'real' scientists are a rare breed indeed these days.
Take a good hard look at post #12 also.
