Ironically, climate disruption would also lead to pockets of extremely cold weather. Farming and Food Weather changes are likely to affect the food supply too. In the short term, warmer and wetter weather in some regions would actually help farmers. Some crops, like rice, will thrive in hot and humid conditions. Other foods, like soybeans, will not.
Every projection shows pretty substantial food-crop loss across Africa and Asia.
That portends a potential disaster. But it's even bad here. If the grain-growing region shifts north year by year, we could adjust. The worry there is that ecosystems sometimes change suddenly and abruptly. So if the change is over one to three years, there is a question of whether we would be able to maintain an adequate supply of food.
