The purpose of Science is to find the truth.
We used to use Cause and Effect, The Scientific Method and a large dose of skepticism.
Today we settle for what a politician can infer from Statistics, Null Hypothesis “Testing,” and voting.
A Scientist tries to prove his idea wrong, and failing to do so he/she is duty bound to ask his/her peers to prove his idea wrong.
After a large number of objective, independent testing of all assumptions, speculations and variables in the idea, it moves from an idea to a speculation to an hypothesis.
IF the peer Scientists cannot objectively prove the idea wrong, THEN a few frustrated peer Scientists will begrudgingly admit that the hypothesis should be tentatively raised to the rare and lofty level of a Theory.
Since the Global Warming Speculation has no known Cause and Effect, it thus remains where it began - - - as an unscientific speculation that is popular with Social Engineers.
Yes skepticism is important to science, but liberals now say you shouldn’t question global warming, and if you do you’re “anti science”. They don’t know what science is, however. They treat it like a belief system, not a methodology. To them it’s group think, with skepticism having no place.
