Global warming caused by human emissions of greenhouse gases is having clear effects in the physical world: more heat waves, heavier rainstorms and higher sea levels, to cite a few. In recent years, though, social scientists have been wrestling with a
murky
question: What will climate change mean for human welfare?
Forecasts in this realm are tricky, necessarily based on a long chain of assumptions. Scientific papers have predicted effects as varied as a greater spread of tropical diseases, fewer deaths from cold weather and more from hot weather, and even bumpier rides on airplanes. Now comes another entry in this literature: a prediction that in a hotter world, people will get less sleep.
In a paper published online Friday by the journal Science Advances, Nick Obradovich and his colleagues predicted more restless nights, especially in the summer, as global temperatures rise. They found that the poor, who are less likely to have air-conditioning or be able to run it, as well as the elderly, who have more difficulty regulating their body temperature, would be hit hard.
If global emissions are allowed to continue at a high level, the paper found, then additional nights of sleeplessness can be expected beyond what people normally experience. By 2050, for every 100 Americans, an extra six nights of sleeplessness can be expected every month, the researchers calculated. By 2099, that would more than double, to 14 additional nights of tossing and turning each month for every 100 people, in their estimation. Researchers have long known that being too hot or too cold at night can disturb anyone’ s sleep, but nobody had thought to ask how that might affect people in a world grown hotter because of climate change.
To calculate the effect of warmer temperatures in the future, Dr. Obradovich turned to data collected by the Centers for Disease Control and Prevention, which asks people in a survey to recall their sleep patterns in the previous month. Sure enough, he found a correlation between higher temperatures in particular cities and disturbed sleep as reported by their residents. To make forecasts, he drew on computer estimates of how hot particular places will get if greenhouse emissions continue at a high level.
Dr. Obradovich acknowledged that a survey about sleep over the previous month was subject to the vagaries of memory. More definitive research would involve putting lots of people in a sleep laboratory and manipulating the temperature to see what happened. "Those ideal data don’t exist and would be prohibitively expensive to collect," he said.
The word "murky" (Para.l) is closest in meaning to______.
选项
A、considerate
B、rediculous
C、easy
D、complicated
答案
D
解析
含义题。根据题干关键词定位到文章第一段第二句。wrestle with意为“全力对付;努力克服”,由此可知murky一词所修饰的“问题”难以解决。故D项“复杂的”为正确答案。considerate“体贴的”、rediculous“荒谬的”和easy“容易的”均与题意不符,故本题选D。
