The "fog-of-war" prevents highlighting some risks specifically; a metric presents a useful summary.  World GDP will be 50% WMDs mid-century.  ex) specific synthetic biology blueprints won't be listed here as a malevolent program may read this, but the world's financial community would now consider it desirable to Cat's Cradle the biosphere. 
AGW and Nuclear War barely don't make the metric.  We will have directed energy weapons on captured NEOs and on the Moon that may increase WWIII odds enough some decade.  AGW can be unleashed by robots or stopped by humans using Bigelow spaceships and these kinds of risks along with electric battery R+D are why my own Sphagnum fuscum afforestation of the Hudson's Bay coast is not a priority.
