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.
That was beautifully written. Kudos.
