Scientists have long predicted that warmer temperatures caused by climate (气候) change will have the (big) influence on the world's poorest people. New research now suggests that it has already happened over the past years.
A study coming out in the Proceedings of the National Academy of Science (find) that in most poor countries, (high) temperatures are more than 90% likely to have resulted in a fall in economic output (经济产量), compared to a world without global (全球的) warming. The influence has been less big in richer (country)—with some even benefiting (获益) from higher temperatures.
"We're not saying that global warming created inequality (不公平)," says Noah S. Diffenbaugh, the writer of the study and a professor at Stanford University who studies climate change. But "global warming has slowed down the improvement", the poorest countries (face) the worst influence of rising temperatures-for which they are least responsible, he adds.
