全球变暖会打击美国穷人 @ 科学美国人60秒5 This is Scientific American — 60-Second Science. I'm Christopher Intagliata. In President Trump's June 1st speech withdrawing the U.S. from the Paris Climate Accord, he claimed the climate __1__ was costing American workers. In a whole lot of ways: "In terms of lost jobs, lower wages, shuttered factories, and vastly __2__ economic production." Of course, doing nothing about climate change is also an __3__. But what is the economic price...of that choice? A team of economists and scientists se??t out to answer that question, by __4__ up economic and climate models to estimate how much warming temperatures could cost the U.S. economy. And they found that for every degree Celsius the __5__ goes up? It docks the U.S. gross domestic product, the GDP, by 1.2 percent. But that economic __6__ will not be evenly applied. Because the southern U.S. is already much poorer than the northern U.S. today. Oh, and it's hotter, too. "You know, if you're already a really hot __7__, h?eating up is really harmful." Solomon Hsiang, an economist at UC Berkeley. "Going from 70 to 75 isn't nearly as bad as going from 90 to 95." Add in more hurricane damage, smaller crop __8__, lost jobs, an increase in death and disease—and the analysis finds that climate change could eat up 20 percent of the poorest counties' income by the end of the century. "Effectively we're harming the poorer populations and in some cases we're actually helping the relatively wealthier northern populations. So this means that climate change can actually increase __9__ within the United States." The study is in the journal Science. Warming temperatures probably won't help President Trump reach his forecasted three percent growth rate for the U.S. economy, either. "You know, this is essentially gonna slow down the growth rate gradually." In other words: it won't be a good climate for __10__.
