      Most scientists are now certain that global warming is taking place．Gases such as carbon

dioxide produced by burning of coal, oil, wood, together with industrial pollution, are creating a

warm blanket around the earth．This blanket is trapping heat in the atmosphere and so raising the

temperature of the earth.

      The evidence for global warming can now be seen in the world’s changing climate statistics．In

Europe, eight of the last ten years have seen record high temperature．For northern Europe, this has

generally been a change for the better．Gardens can even now grow tropical（热带的） plants in

England, though London may never see a “White Christmas” again．On the other hand, the

countries around the Mediterranean Sea, and those south of the Sahara desert are receiving even

less rain than before．In sub-Saharan Africa the crops are drying out in the fields and people are

dying of starvation．In the Americas, the climate is becoming more extreme ---the summers are

getting hotter and hotter and the storms are becoming more violent．In 1999 the southern United

States was struck by a series of destructive hurricanes, while the end of 1999 saw the worst floods

ever in Venezuela．Meteorologists（气象学家） expect such trends to continue, and indeed to

worsen, if global warming cannot be halted(终止).

In addition to worrying about rising global temperatures and more extreme weather conditions,

scientists are closely monitoring（监测）sea levels around the world．These are slowly rising, as the northern and southern polar ice-caps start to melt．This will have serious consequences for low-lying countries near the sea, such as the coral islands in the Pacific, and Bangladesh where the River Ganges already folds the delta(三角洲) every year．Already parts of these places are disappearing under the rising tides.
