Natural world heritage sites at risk 2100, by warming scenario
By the end of the century, around *** natural world heritage sites will be at risk of heat, drought, or extreme rainfall under an intermediate emissions scenario (SSP2-4.5), which results in around *** degrees Celsius of warming. This represents ** percent of all natural world heritage sites registered by UNESCO. In a more optimistic scenario of low emissions (SSP1-2.6), which will maintain global temperatures below *** degrees Celsius, the number of sites at risk could be reduced to only ** sites.
