Some desert animals can survive the summer heat and dryness because they are very unusual. The camel, for example, can experience and bear an increase in the temperature of its body and its blood of 9°C without anything bad happening to it. In addition, it can drink a lot of water at one time; then store enough water in parts of its body to supply its needs for two weeks or more. The kangaroo rat, on the other hand, gets all the water it needs from water that it produces when it breathes. However, most animals need to maintain a fairly constant body temperature, and will die if it rises more than 5°C. Therefore, they need to find some way to stay away from the heat of the summer sun.

[单项选择] Earth Will Survive Global Warming, But Will We

A poll conducted last summer by the Pew Research Center found that only 41 percent of Americans believe the burning of fossil fuels causes global warming. But in a meeting this week in Paris, officials from 113 nations have agreed that a highly anticipated international report will state that global warming was "very likely" caused by human activity. The idea that biology can alter the planet in broad and dramatic ways is widely accepted among scientists, and they point to several precedents throughout the history of life.
