I was unclear on the scope of those numbers, they were for US ag, so your number is comparing US drought numbers to the entire world output. Comparing an apple to the entire apple orchard. If we wait to take steps until it’s an even larger problem then we lock in decades of yield being curtailed by weather extremes. In your linked data, 2017 US Ag contribution to GDP is $175B, so almost 10% reduction of the entire nations agricultural output from just drought is significant, and expected to rise.
