Current Pledges to Reduce Greenhouse Gas Emissions Put Over 600 Million People at Risk of Higher Water Scarcity
Sep. 12, 2013 — Our current pledges to reduce greenhouse gas emissions, which are projected to set the global mean temperature increase at around 3.5°C above pre-industrial levels, will expose 668 million people worldwide to new or aggravated water scarcity.
This is according to a new study published today, 13 September, in IOP Publishing’s journal Environmental Research Letters, which has calculated that a further 11 per cent of the world’s population, taken from the year 2000, will live in water-scarce river basins or, for those already living in water-scarce regions, find that the effects will be aggravated.
The results show that people in the Middle East, North Africa, Southern Europe and the Southwest of the USA will experience the most significant changes.
