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 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 expect such trends to continue, and indeed to worsen, if global warming cannot be halted(終止).
In addition to worrying about rising global temperatures and more extreme weather conditions, scientists are closely monitoring 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.

Biomass energy (生物能).often forgotten as a promising alternative (替代物) to oil, received its day in the sun with the gathering of the Bio-Energy World Congress and Exposition in Atlanta, Georgia, late in April, 1990. Nearly 1, 700 scien??tists, businessmen, and policy-makers, one-quarter from the foreign nations, gathered for a week to discuss various means of squeezing usable energy out of trees, crops, manure, sea??weed, algae, and urban waste. Biomass in the United States contributes 2. 5 percent of the total supply, but this amount can be doubled by 2000 and then doubled again by the year 2010.
Eight percent of Sweden’s energy supply, for example, is presently coming from wood bark and pulp remainings, Sweden intends to raise this percentage by more intensive harvesting of waste food lying around in forests, and through the planting of so-called energy forests of fast-growing trees such as willow and birch.
Brazil is frequently pointed to as a nation with a major successful investment (投資)in energy coming from grains: it presently runs 330,000 automobiles on a water and alcohol (酒精) mixture, replacing 10 percent of its previous oil sup??ply. Brazilian representatives (代表) at the conference said they wish to double this in five years, with a final goal of total replacement. Most of the cars are built at the factory to use the mixture, while older models are changed through low-cost gov??ernment programs.
