Climate Change Could Cause Economic Damage

National Journal: “If left un­checked, cli­mate change could worsen the gap between rich and poor coun­tries, ac­cord­ing to a new study.”

“The study, pub­lished Wed­nes­day in the journ­al Nature, found that above a me­di­an ideal tem­per­at­ure, a warm­ing cli­mate stunts eco­nom­ic growth.”

“Over­all, un­mit­ig­ated cli­mate change could shrink the glob­al eco­nomy by 23 per­cent by the end of the cen­tury, based on cur­rent growth in car­bon-di­ox­ide emis­sions.”

“The au­thors looked at World Bank data for 166 coun­tries between 1960 and 2010, com­par­ing it with cli­ma­to­lo­gic­al data, and found that there was an ideal tem­per­at­ure at which coun­tries seemed to be best at eco­nom­ic pro­duc­tion: 13 de­grees Celsi­us, or roughly 55 de­grees Fahren­heit.”

“For coun­tries av­er­aging be­low that tem­per­at­ure, like those in Scand­inavia, a warm­er year meant more pro­duc­tion. Above the bench­mark, however, each de­gree meant less eco­nom­ic pro­duc­tion. That’s due to a vari­ety of factors, in­clud­ing re­duced ag­ri­cul­tur­al out­put and health prob­lems as­so­ci­ated with warm­er tem­per­at­ures.”

“The re­search­ers said that some coun­tries whose av­er­age tem­per­at­ure is be­low the 13-de­gree bench­mark—such as Rus­sia, Canada, and parts of Europe—would ac­tu­ally see an eco­nom­ic boost. In the poorest 40 per­cent of coun­tries, however, the eco­nom­ic hit could be as high as 75 per­cent by the end of the cen­tury.”

    It would force population movements unprecedented in human history. It would make the destruction of World War II, both material and HUMAN look trivial by contrast.

    Overall, if climate change is “left unchecked,” its impacts will be far greater than simply worsening the gap between the rich and poor countries. That’s why our military is conducting regular planning exercises designed to work out contingency plans to deal with the likely security problems that climate change is creating and that will only get worse.

    the information in the article is very interesting, but the headline is dub in a “no duh, that’s obvious and also and understatement” way.
