Whenever I hear a weather report declaring it’s the hottest June 10 on record or whatever, I can’t take it too seriously, because "ever" really means "as long as the records go back" , which is only as far as the late 1800s. Scientists have other ways of measuring temperatures before that, though—not for individual dates, but they can tell the average temperature of a given year by such proxy measurements as growth marks in corals, deposits in ocean and lake sediments, and cores drilled into glacial ice. They can even use drawings of glaciers as there were hundreds of years ago compared with today.
And in the most comprehensive compilation of such data to date, says a new report from the National Research Council, it looks pretty certain that the last few decades have been hotter than any comparable period in the last 400 years. That’s a blow to those who claim the current warm spell is just part of the natural up and down of average temperatures—a frequent assertion of the global—warming-doubters crowd.
The report was triggered by doubts about past-climate claims made last year by climatologist Michael Mann, of the University of Virginia(he’s the creator of the "hockey stick" graph AI Gore used in "An Inconvenient Truth" to dramatize the rise in carbon dioxide in recent years). Mann claimed that the recent warming was unprecedented in the past thousand years—that led Congress to order up an assessment by the prestigious Research Council. Their conclusion was that a thousand years was reasonable, but not overwhelmingly supported by the data. But the past 400 was—so resoundingly that it fully supports the claim that today’s temperatures ale unnaturally warm, just as global warming theory has been predicting for a hundred years. And if there’s any doubt about whether these proxy measurements are really legitimate, the NRC scientists compared them with actual temperature data from the most recent century, when real thermometers were in widespread use. The match was more or less right on.
In the past nearly two decades since TIME first put global warming on the cover, then, the argument against it has gone from "it isn’t happening" to "it’s happening, but it’s natural" , to "it’s mostly natural" —and now, it seems, that assertion too is going to have to drop away. Indeed. Rep. Sherwood Boehert, the New York Republican who chairs the House Science Committee and who asked for the report declared that it did nothing to support the notion of a controversy over global warming science—a controversy that opponents keep insisting is alive. Whether President Bush will finally take serious action to deal with the warming, however, is a much less settled question.
What does this passage mainly deal with?
选项
A、The tendency of earth’s becoming hotter.
B、The assessment of earth’s temperature.
C、The menace of global warming.
D、The measurement of tackling global warming.
答案
A
解析
本题是主旨题。第二段提到“…it looks pretty certain that the last few decades havebeen hotter than any comparable period in the last 400 years.”.过去十几年达到了近400年的最高温度。第三段提到“Their conclusion was that a thousand years was reasonable,…soresoundingly that it fully supports the claim that today’s temperatures ale unnaturally warm…”,数据不能充分说明地球的气温在过去一千年内一直上升,但能证明过去400年里地球温度不合自然规律地在升高。故A正确。
