Since 1990, US emissions have caused an estimated $500bn of economic damage to India and $330bn in damage to Brazil, the research finds. “These are huge numbers,” acknowledged Marshall Burke, an environmental scientist at Stanford University who led the new work. Burke added that the US has “a lot of responsibility, our emissions have caused damage not only to ourselves, but pretty substantial damage in other parts of the world”. This damage is summed up by the new research, which calculates how much global heating has constrained GDP and assigned responsibility for this to countries based on their emissions since 1990. “This differential effect of dollar-valued damages on wellbeing in rich as opposed to poor countries is not considered in the paper.”
