The reasons for this paradigm shift are clearly not based on science. Sure, you can always analyze some dataset in such a way that it gives the appearance of climate stasis (e.g. the hockey stick), but there is plenty of published research over the last 50 years supporting the view that climate changes naturally, and on all time scales…decadal, centennial, millennial, etc.
Our Chaotic Climate System
In this post, Dr. Roy Spencer asserts that climate change is more a result of changes in the environment from natural causes or cycles, and not by man-made causes. He writes that,
Over the last quarter century, mainstream climate science has changed dramatically, from a paradigm where climate changes naturally to one where climate forever remains the same unless humans meddle with it.
