A few studies have examined possible occurrences of tele-connected yield losses  using future climate scenarios. Tigchelaar  estimated that, for the top four maize-exporting countries, the probability that simultaneous production losses greater than 10% occur in any given year increases from 0% to 7% under 2℃ warming and to 86% under 4℃ warming. Gaupp  estimated that risks of simultaneous failure in maize would increase from 6% to 40% at 1.5℃ and to 54% at 2ºC warming, relative to the historical baseline climate. Large-scale changes in SST are the major factors causing simultaneous variation in climate extremes, which are projected to intensify under global warming . Consequently, risks of simultaneous yield losses in major food-producing regions will also
