I would argue that predictions of the climate 100 years in the future are not real science -- they are climate astrology !
Below is a link to a real climate scientist's February 3, 2016 testimony to Congress, which includes this quote:
'I’ve often stated that climate science is a “murky” science. We do not have laboratory methods of testing our hypotheses as many other sciences do. As a result what passes for science includes, opinion, arguments-from-authority, dramatic press releases, and fuzzy notions of consensus generated by pre-selected groups. This is not science." John Christy, PhD
