I had planned to write a long post with more of my own ideas based off of this essay at Watts Up With That: The Climate-Grain Production Relationship Quantified. But instead, work intervenes again, and here is the nugget. You should certainly read the linked article too.
It should be relatively obvious that the sooner in the year that it gets cold and the later it gets warm, the fewer crops can be grown. I am sure I have beat the solar cooling drum before, though not to peddle alarmism. Rather to argue for genetically modified food and the unleashing of human potential to innovate and not just survive a potentially upcoming ‘little ice age’ but to this time avoid civilizational collapse as well. First, here is a graphic of the past and predicted solar cycle: Of course, you should for this post ignore the fact that the global warming of the previous decades is surprisingly coincident with a solar maximum. instead, notice that the possible loss in corn yield, 21% loss… and who would this affect most? Well, everyone of course, since problems in the middle east and Asia very rapidly become everyone’s problems.
However, rather than shout Doom! we should follow Mitch Daniels’ advice.
