Climate change putting 4pct of global GDP at risk, new study estimates

Climate change could see four percent of global annual economic output lost by 2050 and hit many poorer parts of the world disproportionately hard, a new study of 135 countries has estimated.

Rating firm S&P Global, which gives countries credit scores based on the health of their economies, published a report on Tuesday looking at the likely impact of rising sea levels, and more regular heatwaves, droughts and storms.
