Hank Green of the SciShow ((An interesting take on science communication: hat tip to Emma for pointing me at it.)) gives his take on the scariest things happening (or that could happen) because of climate change. Hank’s most frightened by the potential for a complete shutdown of the oceanic thermohaline circulation, which would be almost unimaginably nasty ((If you want more info, have a read of Peter Ward’s Under A Green Sky)), but there’s plenty to think about in his list — even if you disagree with it.
