A decade ago, the idea that the planet was warming up as a result of human activity was largely theoretical. We knew that since the Industrial Revolution began in the 18th century, factories and power plants and automobiles and farms have been loading the atmosphere with heat-trapping gases, including carbon dioxide and methane(甲烷). But evidence that the climate was actually getting hotter was still murky.
Not anymore. As an authoritative report issued a few weeks ago by the United Nations-sponsored Intergovernmental Panel on Climate Change makes plain, the trend toward a warmer world has unquestionably begun. Worldwide temperatures have climbed more than 0.5℃ over the past century, and the 1990s were the hottest decade on record. After analyzing data going back at least two decades on everything from air and ocean temperatures to the spread and retreat of wildlife, the IPCC asserts that this slow but steady warming has had an impact on no fewer than 420 physical processes and animals and plant species in all countries.
Glaciers(冰川), including the legendary snows of Kilimanjaro, are disappearing from mountaintops around the globe. Coral reefs are dying off as the seas get too warm for comfort. Drought is the norm in parts of Asian and Africa. El Nino(厄尔尼诺)events, which trigger devastating weather in the eastern Pacific, are more frequent. The Arctic permafrost(永久冻土带)is starting to melt. Lakes and rivers in colder climates are freezing later and thawing earlier each year. Plants and animals are shifting their ranges pole-ward and to higher altitudes, and migration patterns for animals as diverse as polar bears, butterflies and beluga whales are being disrupted. [br] What is the best title for the passage?
选项
A、Life in the Greenhouse
B、How Does Our Planet Get Warmer?
C、We Are Making the World Warmer
D、Everything Is Melting
答案
A
解析
主旨题。文章主要是在介绍全球变暖对于地球上生物生活的影响,并没有介绍变暖的原因和责备人类造成了气候变暖,故B和C错误。D项过于偏颇。故选A。
