This reminds me of Department of Defense Climate Risk Analysis from three years ago where they remind us that there will be increased international conflicts due to the effects of climate change:
Interesting (and very plain, understandable, commonsensical) - but of course some running conflicts are not not strongly related to climate change.
Of course, when Niall Ferguson spoke, it looked at the contingency: he sees a possibility of catastrophic consequences that may come much earlier than the climatic "Armageddon". (Well, in some news peices today they spoke about "before Xmas"... It makes the order of events very definite.)
