Hi Simon, I think that falling rice yields because of rising nighttime temperatures is the tip of the iceberg. One of my readers on LinkedIn pointed out that wheat is similarly affected. My guess is corn or maize, the other great annual food staple is as likely to be impacted as well. We can scramble to create new crop strains that can beat the heat or we have to find other food sources to provide adequate nutritional replacement to cover the delta in yield rates. You can imagine just how destabilizing declining crop yields can be on countries that today are struggling to feed their populations. These are the most vulnerable people and political instability at best will be the end result. At the worst we will see famine and climate change induced mass migration putting pressure on neighboring countries that are not as afflicted. I hate Doomsday Scenarios but adapting to climate change and mitigating the worst impacts of increased carbon in the atmosphere and oceans requires immediate action so that we have the tools in place to lessen the blow.
