"Science" has a lot to answer for.
It's ideology, pure and simple. Pure, blind, irrational ideology.
If crop failures do occur, then we will grow different crops, or grow them in different ways. Agriculture on this planet spans a very wide of climatic conditions.
It is *ideology* which says that agriculture is not possible outside of a niche.
It's like medieval theology.
How are you supposed to argue a fantasy counterfactual factoid?
Until the role of ideology is understood, the science does not mean anything.
Of course. But the point stands: science has not lifted his understanding. Yet it is the institution his argument implies we must respect and defer to.
But it gets worse than that.

"... in fact the opinions of presidents of the oldest scientific academies are no better than the opinions of the bloke at the pub..."
