原文答案：
Scientists issued reports on the severe climate changes that could result from the "greenhouse effect" — the gradual warming of the atmosphere caused by an increase in carbon dioxide levels from the burning of fossil fuels, saying that average global temperatures could start to rise within a few decades and reach levels nine degrees Fahrenheit higher than today's temperatures by the end of the next century. This, experts said, could create dangerous changes to global weather patterns. For instance, it could change annual amounts of rainfall, swell or dry up rivers, and raise the level of the seas.
While admitting that this forecast was somewhat uncertain, scientists warned against treating it as a cry of wolf. Although there is considerable debate over how severe the greenhouse effect will be, one thing seems certain: Carbon dioxide levels are on the rise.
