Warming of the planet by 3 degrees Celsius may cost the world up to 10 per cent of its GDP, a new research has found. It also found that poorer, tropical countries could see the worst effects -- up to 17 per cent GDP loss. The study -- led by ETH Zurich, Switzerland, and published in the Nature Climate Change journal -- suggested that roughly half of the predicted global economic damage could be related to extreme heat, with heat waves being the most impactful among the extreme events analysed. "Impacts are more severe in the Global South and highest in Africa and the Middle East, where higher initial temperatures make countries particularly vulnerable to additional warming," the authors wrote. The researchers further found that the cost of climate change increased around the world after accounting for changes in rainfall and temperatures occurring within a short span at a location. "If we take into account that warmer years also come with changes in rainfall and temperature ... Read The Rest at :
