Wouldn’t it be great if you could just look up at the sky and read the weather forecast right away? Well, you can. The forecast is written in clouds. If you can read that writing, you can tell something about the atmosphere. With some practice, you can become a pretty good weather forecaster. Who knows, you might even do as well as meteorologists（气象学家）.

Meteorologists use much more information than just the appearance of the clouds to make their forecast. They collect data（数据）from all over the world. Then they put it into powerful, high speed computers. This does give the meteorologists an advantage, because they can track（追踪）weather patterns as they move from west to east across the country. But you have an advantage, too. You can look at the sky and get your data directly. A meteorologist uses a computer forecast that’s several hours old to make a local forecast.

What are you seeing when you look at a cloud? “A picture of moisture(水汽)is doing in the atmosphere,” says meteorologist Peter Leavitt. There’s moisture throughout the atmosphere. Most of the time you don’t see it, because it’s in the form of an unseeable gas called water vapor. Sometimes, the temperature of the air gets cold enough to cause the waster vapor to change to liquid water. It’s called condensation(凝结), and we see it happen all the time (for example, when humid air from the shower hits the cold glasses of a mirror). When enough water vapor condenses（冷凝）, droplets(小滴）come in the air. These droplets scatter(分散) light. A cloud is seen.

Watching clouds over a day or two tells you a lot more than a single cloud about the weather to come. Changes in clouds show changes in the atmosphere. You should begin to notice patterns. Certain clouds, following each other in order, can signal an approaching storm. But don’t take our word for it; see for yourself.

WASHINGTON—Two-thirds of the world’s polar bear population could be gone by 2050 if predictions of melting sea ice hold true, the US Geological Survey reported on Friday.

The fate of polar bears could be even worse than that estimate, because sea ice in the Arctic might be disappearing faster than the available computer models predict, the geological survey said in a report aimed at determining whether the big white bear should be listed as a threatened species.

“There is a definite link between changes in the sea ice and the welfare of polar bears,” said Steve Amstrup, who led the research team. He says Arctic sea ice is already at the lowest this year and is expected to retreat(退却) farther this month.

That means that polar bears—some 16,000 of them -- will disappear by 2050 from parts of the Arctic where sea ice is melting most rapidly, along the north coasts of Alaska and Russia, researchers said in a telephone briefing(简报).

Other polar bears could survive beyond that date but many of those could be gone by 2100, Amstrup said. By this century’s end, the only polar bears left might live in the Canadian Arctic islands and along the west coast of Greenland.

“It is likely to result in loss of approximately two-thirds of the world’s current polar bear population by the mid 21st century,” the report’s executive summary said.

“Because the observed trajectory(轨迹)of Arctic sea ice decline appears to be underestimated by currently available models, this assessment of future polar bear status may be conservative(保守的).”

In January, the US Fish and Wildlife Service proposed listing the polar bear as a threatened species, noting polar bears depend on sea ice as a platform to hunt seals, their main food.

Without enough sea ice, polar bears would be forced onto land, but they are poor hunters once they get out of the water and ice, the researchers said. The bears’ disappearance would probably take place as young cubs(幼兽)failed to survive to adulthood and females were unable to reproduce successfully.

1.What was the US Geological Survey intended to do?

A. To determine whether the polar bear was in danger.

B. To measure how fast the sea ice melts in the Arctic.

C. To check the predictions of the computer models.

D. To find out the exact number of the polar bear.

2.What causes the polar bears to disappear by 2050?

A. The pollution of the Arctic region.    B. The sea ice melting at high speed

C. Fewer food sources being left.         D. The temperature getting colder.

3.The key to preventing polar bears dying out seems to _______________.

A. help young polar bears to survive the cold winter

B. have large number of seals living in the oceans

C. make sure there is enough sea ice in the Arctic

D. provide chances for adult polar bears to reproduce
