>> We are starting to see crop yields decline in some tropical countries We are seeing crop yields rise in other tropical countries. The prediction wasn't that crop yields would fall in some countries and rise in others with the overall result being steadily increasing food production per capita through the 2020's. The prediction was massive famine with hundreds of millions dead in the 1970s spreading to the industrialized world by 2000. And the prediction wasn't based on climate change, it was based on simple population growth. We currently have the lowest percentage of people living in absolute poverty in all of human history. And the birth rate is under the replacement birth rate almost everywhere outside of Africa. The doom population explosion scenario that was predicted simply did not happen. Technology won.
