Climate change and the shape of the earth are science. Economics is not.
Economics is not science? Lol in what world is this true?
There is a clear distinction between the hard sciences (physics, chemistry, etc.) and social sciences (economics, political "science"). Those in the latter camp seem to be more anxious about their status as a "science" then those in the former. I wonder why.
You will need to back this up. I don't think economists care about their status as a "science". Economists know their worth and can be just as influential as Chemists, or physicists. In fact, economists are far more memorable than the former.
