There is robust evidence of the impacts of all climate hazards on the key livelihood resources that the poor depend on. There is high confidence that two climate hazards pose high risk to a broad range of livelihood resources: warming trends and droughts. Meanwhile, the livelihood resources that are globally at greatest risk include people's bodily health, food security and agricultural productivity . Evidence suggests that the fundamental challenge of climate change to livelihoods is that rising temperatures, drought and other hazards endanger human life, and the lives of plants and animals that humans rely on to survive . There is now robust evidence that the impacts of climate change on livelihoods are driving people to migrate in search of alternative incomes, and this tendency will increase with rising temperatures. Of greatest concern are people whose development context is compromised by war, conflict and extreme poverty and inequality, such as refugee populations and displaced people.
