I mentioned this last August: nuclear plants are thirsty. Though they help with the carbon problem, they are also vulnerable to climate shifts. (The article I referenced then seems to have expired.)
(Why are newspapers so silly? I am sure that paid archives achieve less for them than ongoing advertisements. The NY Times seems to have figured it out...)
Here's another article in the same vein: the southeastern drought is causing power shortages over there by shutting down nukes. Let's hope that this eases before the summer cooling season kicks in.
