Global conflict experts say the Obama administration’s recent focus on climate change as a national security threat may be misguided. “The link between global warming and national security needs is tenuous at best, though the Arctic might be an exception, if [Russian President Vladimir] Putin continues his revanchist ways,” Harvard psychology professor and best-selling author Steven Pinker said in a recent e-mail interview. “Most wars have nothing to do with climate, and vice versa.” --David O.
