The study looks at the likely impact of rising sea levels

and more regular heat waves, droughts and storms

on the health of countries' economies

It found that up to 4% of global economic output could be lost by 2050

with poorer parts of the world being disproportionately affected

South Asia has 10%-18% of its GDP at risk

while Europe is estimated to be the least affected region
