All they know for sure is their current crop of models are oversimplified and dangerously useless for predicting the kind of extreme events coming their way. ( But I bet the graphics are real impressive.)

Crop production is way above what it was decades ago, and still
increasing.
So, John Larkin is a fan of underestimation.
No, I\'m a fan of feeding the poorest people on the planet.
That\'s what he likes to claim. Sadly, he doesn\'t have a clue how this might be done, but sustained doses of climate change denials propaganda have convinced him that burning more fossil carbon as fuel is a necessary part of the process. The Agricultural Revolution got going in Eng;land from 1700. before the Industrial Revolution and without burning any coal.
Feed them, educate them: that\'s the path to progress and general happiness and, indeed, to population control.
All true, and all quite independent of burning fossil carbon. Use solar cells to charge the batteries that let the school children stays in the evening. Burning the midnight oil was never good for the atmosphere, and it was bad for the lungs of the students.
Mankind\'s agricultural output was outright paltry until mechanization came along.
The Agricultural Revolution meant that half the population could feed the other half. That\'s paltry compared with mechanised agriculture, but it was enough allow the industrial revolution, and Russia industrialised without doing much better.
Don\'t know about other places, but U.S. was just starting total mechanization in the 1940s. The result was acres in cultivation per farmer took off exponentially. And this is gas/ diesel combustion engine mechanization. There was steam powered mechanization around in the mid-19th century, but it wasn\'t in wide use and ordinary farmers weren\'t using it.
It made a great deal of difference, but the third world doesn\'t need to get that far to do much better than it is doing at the moment
The problem with primitives in the third world is farming practices are more of a cultural tradition than anything else, and they don\'t want to be told to change. You can give them a bunch of state of the art farm equipment and they let it sit idle and rust.
There may have been other limitations that made steam impractical, like all these machines weighed 20 tons and the engines were weak. I saw a steam powered machine designed to lay drainage tile. Looked like something from a Jules Verne story. Tires were out of the question, they used big heavy wheels, with spikes for traction.
Solar and windmill powered mechanisation is quite a enough get beyond the original Agricultural revolution. The world isn\'t required to recapitulate the European industrialisation of agriculture to get to European agricultural outputs, and the third world doesn\'t need to eat as much meat as Americans do - in fact it should eat rather less (and so should Americans).
There are other aspects to farming. It\'s estimated that without modern herbicide and pesticide application, modern output would decline by 70%.
Nitrogen is a big deal, and synthetic fertilizers make a huge
difference. Crop rotation is very inefficient.
