High risks to crop production are assessed to occur in Africa with ~1.5- 2°C warming , to agriculture in North America with ~1.5℃ warming , and with ~2.8℃ in Europe . High risks of mortality and morbidity due to heat extremes and infectious disease are assessed to be reached in Africa with ~1.5℃ warming ; heat stress, mortality and morbidity in Europe are assessed to reach a high level of risk at ~2℃ . Heat- related mortality risk transitions to a high level by ~1.5-2℃ warming in Australasia, while cascading effects on cities reach high risk with ~1.2°C warming . Risks to water scarcity, forestry, tourism and transportation in North America are projected to reach high levels with ~2℃ warming .
