The U.N.-sponsored Intergovernmental Panel on Climate Change(IPCC)report released tod ir Brussels has a familiar rin9. As the climate disasters headlined recently--intense hurricanes,drought ir the American West,Arctic thawing--bee monplace in a greenhouse world,plants,animals,and peopIe will suffer.That has been the presumption,but the latest report from the IPCC projecting greenhouse lmpacts calculates mounting costs that will fan the heiest on the world’s poor.
February’s IPCC report on the physical science of climate firmly links most of the recent warming of the worjd to human activity.Scientists authoring the second report had a tOugher challenge:figuring ouI the llkely consequences. To do that,they considered 29,000 datasets from 75 studies. Of those daca series,89%showed changes--receding glaciers or earlier bloomin9,for example—consistent with a response to warmlng.Because those responses usually occurred where the warming has been greatest, the scientists concluded that it’s“verY unlikelythe changes were due to natural variability of climate or the system involved.“For the first time,we concluded anthropogenic warming has had an influence on manY physical and biological systems,”says Cynthia Rosenzweig of NASA’s Goddard Institute for Space Studies in New York City,a coordinating lead author on the reDort.
The IPCC scientists also projected the effects of future warming.Assuming that nothin9,s done to slow greenhouse emissions,the February report predicted a temperature increase of roughly 3℃toward the end of the century,drying at lower latitudes, more precipitation at higher iatitudes, and rising sea levels.“This report finds that such a warming will bleach most coral reefs by mid—centur),,drying will be91n decreaslng crop yields at lower latitudes within a few decades,and sea level rise and tropical cvclone Intensl±1catlon will increase the likelihood of millions of people being flooded out each year on rjver mega. deltas such as that of the Ganges—Brahmaputra in southern Asia.Bottom line?“You don’t want tO be poor and living on a river delta or the Florida coast,”says c11mate scientist Stephen Schneider of Stanford University,a coordinating lead auth。r. The Door especially subsistence farmers--tend tO be more vulnerable to climate change,notes the reort.And they are least able to adaPt,say by building levees against storms or dams for irrigation.Schneider’s ther advice:“Trry not to go over 2℃ or 3℃ because that triggers the really nasty stuff.With that much warmlng,the bad effeCts of this century only get worse,and the rare benefits,such as higher crop vields in wetter areas,fade.[422words]

①EAs the climate disasters(headlined recently)jntense hurricanes,drought in the American West,Arctic tha wing--bee monplace in a greenhouse world],plants,animals,and people will suher.
【结构】方括号所标示的“As the climate disasters…bee monplace…world”是原因状语从句。
圆括号所标示的过去分词短语“headlined recently”是“disasters”的后置定语。破折号之间的部分是对“climate disasters”的补充说明。本句的主句是“plants,animals,and people will suffer”。 examda
【释义】最近以大字标题报道的强烈飓风、美洲西部干旱、极地冰层融化等气候灾难,在这个温室效应主宰的地球上,已然司空见惯。动植物和人类将要遭受其摧残。
②”That has been the presumption,but”the latest report from the IPCC Fprojecting greenhouse impacts]calculates mounting costs[that will fall the heiest on the world’Spoor].
【结构】本句是由逗号和“but”连接的两个分句组成的并列句。方括号所标示的现在分词短语“projecting green— house impacts”是“report”的后置定语。方括号所标示的“that will fall…poor”是“mounting costs”的后置定语从句。
【释义】这是人们一贯的想法,但是,政府间气候变化专门委员会预测温室效应影响的最新报告认为,世界上的贫穷人口将要为此承受最沉重的代价。
③Of those data series,89%showed changes receding glaciers or earlier bloomin9,for example--l-consistent with a response to warming].
【结构】破折号之间的部分是对“changes”的补充说明。方括号所标示的形容词短语“consistent with…warming是“changes”的后置定语。
【释义】其中89%的资料表明,像冰川消融或开花期提前这样的变化与气候变暖的影响相一致。
④[Because those responses usually occurred(where the warming has been greatest)],the scientists concluded Ethat it’S“very unlikely”(the changes were due to natural variability”of climate or”of the system
