The US will be hit harder than almost any other country by climate change,according to a major new report.
The research is the first time that researchers have developed a reliableset of data that allows each country to know just how much economic damage willbe done by carbon dioxide emissions. And the surprising results show thatconsiderable damage could be done to some of the world's greatest powers.
The three countries set to lose the most from climate change are UnitedStates, India and Saudi Arabia, according to the new research. The findings relyon measuring the social cost of carbon, in an attempt to understand how much islost through climate emissions.
And it also found that the damage being done worldwide by those emissionsis significantly higher than in estimates used by authorities including the USgovernment.
The social cost of carbon is a measure designed to take into account thefull price that harmful emissions have to the economy. Often, politicians andcompanies argue that the cost is relatively minimal – it doesn't hurt theenvironment in any immediate way, and could initially benefit the economythrough increased crop yield in some regions – but SCC aims to take into accountthe full cost over time.
The measure is used, among other things, as a way to work out the true costof policy decisions. The US Environmental Protection Agency, for instance, usesit as a way to inform decisions.
