Holding global temperature rise to 1.5C would lead to significant economic benefits by the end of the century, a new paper suggests. The paper uses a new approach to project how different temperature rises could affect global gross domestic product (GDP). It finds that per capita GDP would be 5% higher by 2100 if temperatures are stabilised at 1.5C above pre-industrial temperatures rather than 2C. The negative economic impacts are expected to fall disproportionately on the world’s poorest countries, the lead author tells Carbon Brief, with the disparity larger at 2C than for 1.5C.
