Researchers have quantified how climate change risks to human and natural systems increase at a national scale as the level of global warming increases. A collection of eight studies — all focusing on Brazil, China, Egypt, Ethiopia, Ghana and India — shows that the risks of drought, flooding, declines in crop yields, and loss of biodiversity and natural capital greatly increase for each additional degree of global warming. The overarching picture for the accrual of climate risk across these countries as global warming increases from 1.5 C to 4 C above pre-industrial levels is presented.
