A wide range of climate change impacts depend strongly on development pathway . A low  exposure future, determined by limited population growth and urbanisation, results in about 30% fewer people exposed to extreme heat globally  and about 50% fewer in Africa , similar to the effect of a medium versus high level of global warming. Low-exposure conditions also reduce the fraction of the population in Europe at very high risk of heat stress from 39% to 11% . Demographic differences lead to a reduction in the global population exposed to mosquitos acting as viral disease vectors by more than half  and exposure to wildfire risk by nearly half .
