Climate change and terrorism are both major threats with catastrophic potential. This either or argument is at right angles to what needs to be done. What happen to our climate if a terror attack sets off a nuclear exchange? Our climate will not be untouched if say Pakistan and India exchanged a few nukes. Sound like a remote possibility? Yes it is, so far. But far less remote than before those countries had nukes, and this deep terror problem.

In both instances the worst case is a disaster we really could have avoided.

Nuclear winter would be a sub optimal solution to global warming.

Don’t we really have to address both issues at the same time? Neither threat is wise to ignore.
