Actually I just finished reading David Wallace Wells weekly climate newsletter this morning and it speaks to this point. He talks with two agricultural economists about the "Global food shortage" and asks them how real it is.

The answers are complicated.

However, they both argue that there isn't a "food crisis", instead we are having a "food pricing crisis". Which, WTF does that mean?

It reminds me of the old joke about how physicists answer the question of "how far can a catapult throw a cow". They
always start their answer with, "well, if we assume that the cow is a perfectly round sphere".

You get an answer but is it meaningful in the real world.

These guys want to start with, well if we look at it from the viewpoint of total calories produced each year then there is no shortage. Great, except that's a really abstracted way to think about it. So abstracted that personally I think it's meaningless.

Still, they both make a good point. The US converts enough corn onto ethanol to provide calories for over 1 billion people. I didn't think we were still doing that stupidity.

Simply shutting that down would help enormously.

So, I am going to have to look at this some more. It may be my next piece.
