ECONOMIC IMPACT

Extreme weather could reduce global gross domestic product (GDP) by up to 1%
A two to three degrees Celsius rise in temperatures could reduce global economic output by 3%
If temperatures rise by five degrees Celsius, up to 10% of global output could be lost. The poorest countries would lose more than 10% of their output
In the worst case scenario global consumption per head would fall 20%
To stabilise at manageable levels, emissions would need to stabilise in the next 20 years and fall between 1% and 3% after that. This would cost 1% of GDP
