You can point the finger at all sorts of participants in this battle, but I believe (and we have been examining and discussing at length on this site for more than 8 years now) the principal drivers of the polarization are
coming more from: (1) the corporate energy interests who are protecting their profits
against regulation and other policies that would move the system away from fossil fuels, and using their clout in the political process to tie things
up; (2) right - wing anti-government and anti-regulatory ideologues whose political views appear threatened by scientific conclusions that point toward a need for stronger policy action; (3) people whose
religious or cultural identities appear threatened by modern science; and so forth.
