A suggestion that drives conservatives into mocking meltdown is not so crazy, but I have a few comments to make:
* it's funny how we don't always hear about dire, record breaking droughts if they are in parts of the world we don't care about;
* this part of the article makes sense:
Of course, scientists and security consultants get nervous when the media covers studies such as this one. They worry, in particular, about the impression that wars can be reduced to a single cause. (As one told The Guardian in May about the PNAS study, “I’ll put this in a crude way: No amount of climate change is going to cause civil violence in the state where I live (Massachusetts), or in Sweden or many other places around the world.”)* I see that one of the most worrisome nations in the world for instability - Pakistan - has an ongoing drought issue, too.
