| A. The likely reason of global warming B．Global warming-a world problem C．The fast increase in recent years D．What we should do to avoid greenhouse gases producing E．The earth is becoming warmer F．Different opinions on the cause of global warming |
| 1________ Is the world warming up? According to many reports, the answer is yes. Eleven of the hottest years since 1850 appeared between 1995 and 2006. Last year, the United Nation's Intergovernment Panel on Climate Change (IPCC) reported the earth was about 0.75 ? warmer than it was in 1850. While this doesn't sound like a lot, a small difference in average temperature can make a big difference in climate. During the last Ice Age, the planet was only about five degrees colder than now. 2．________ It's all about the speed at which temperatures are changing. In the past,temperatures moved up or down step by step. But in the 20th century, especially since 1976, temperatures have likely risen more quickly than during any century in the last 1000 years. Warming may bring improved harvests to northern countries such as Canada and Russia. However, many species won't like these conditions. They begin moving towards cooler places and cause lots of trouble to human world. 3．________ The IPCC reported that human activity is very likely responsible for increasing the greenhouse effect. Some gases cause the air to take in heat energy. Without the greenhouse effect, the earth's average temperature would be－18? rather than the present comfortable 14.6 ?. The main greenhouse gases are carbon dioxide, water vapor and some other gases. Burning oil,coal and waste add to the carbon dioxide, and it has increased 35% since 1850. 4．________ Many researchers have found that natural forces alone don't explain the temperature increases over the last 30 to 40 years. Their study shows that as carbon dioxide goes up, temperature will rise, too. But some scientists don't agree. They think the effect of human produced greenhouse gases is very small compared to the normal changes that the climate causes. 5．________ When asked whether humans are causing the world warming,Carl Wunsch, a professor at Massachusetts Institute of Technology says, "It seems very likely from what I've seen. Is it 100% sure? No. There is something to do with natural changes." Does that mean we should have a "waitandsee" attitude? No. He points out we buy house insurance not because we are sure our homes will be on fire, but because it's a danger we'd rather avoid. |
The killer bees are coming! By the time you read this they will have reached Texas. They will also reach all the warmer areas of the United States. Scientists as well as farmers wait for them with a mixture of fear and wonder.
The killer bees should not be coming at all. Nature did not put them on this direct path for the United States; human beings did. The killer bees are from Africa. But in 1957 a scientist from Brazil got some of these killer bees for his experiments. The aim(目的)was to produce a better bee. However, an accident happened: a guest beekeeper let twenty-six of the queen bees escape by mistake. Before long, groups of killer bees took off for the woods.
