There was no such thing as climate change science back then. It was a sort of multi disciplinary effort, so no "climate change" umbrella term existed. In fact even today it is not given to be taught in schools, it has been in and out of the curriculum for 20 years but not before then.

It is university level.

Maybe you read so much nonsense propaganda you have convinced yourself,

Back in the 60's you dissected rat, learnt about rock strata, the period tables and not much else, It was rudimentary and did not include study such complex earth systems.

It is well known the fake news luvvies have created, No basis in fact, but does prove that there is always the fringe dwellers with their alternate reality.

Back then any review of the science shows they were equally concerned about warming as they are today.

They have been consistent , the lesson is the scientists have not changed their veiws at all, If you choose to listen to whacko teachers, or nutter like Craig Kelly then the nonsense views are on you. Sceince has not faltered.
