For those who are not scientifically trained, how does one assess the statements made by policy advocates anywhere, knowing 1) (left-wing)politics abounds in funding, prestigious Chair awards, Nobel Prize selections, tenure, etc., and 2) the media will not expose the lies and exaggerations when the policy advocates are lefties? This is really troubling since real science should be very highly respected. Certainly it can't be true that the world is drifting to a new ice-age (as alleged in the 70's), and is now shifting to global warming, a mere 30 years later. So many non-scientific people can smell a rat but can't say for sure what's true and what isn't. The socio-economic logic of division of labor means that many people have come to specialize in non-scientific professions and cannot independently assess the veracity of coordinated "scientific" scams. It seems that in the long run if Science can't be relied upon to be truthful then real progress for mankind is unsustainable.
