Global Warming
Few people now question the reality of global warming and its effects on the world's climate. Many scientists (1) put the blame for recent natural disasters on the increase (2) in the world's temperatures and are convinced that, more than (3) ever before, the Earth is at (4) risk from the forces of the wind, rain and sun. (5) According to them, global warming is making extreme weather events, (6) such as hurricanes and droughts, even more (7) severe and causing sea levels all around the world to (8) rise.
Environmental groups are putting (9) pressure on governments to take action to reduce the (10) amount of carbon dioxide which is given (11) off by factories and power plants, thus attacking the problem at its source. They are in (12) favour of more money being spent on research into solar, wind and wave energy devices, which could then replace existing power (13) stations.
Some scientists, (14) however believe that even if we stopped releasing carbon dioxide and other gases into the atmosphere tomorrow, we would have to wait (15) several hundred years to notice the results. Global warming, it seems, is here to stay.

全球变暖
现在很少有人质疑全球变暖的现实及其对世界气候的影响。许多科学家把全球气温上升归咎于最近的自然灾害，他们确信，地球现在比以往任何时候都更受到风、雨和太阳这些力量的威胁。据他们说，全球变暖制造了极端天气事件，例如飓风、干旱，甚至更为严重的以至于世界各地的海平面上升。
环保团体对政府施加压力，要求政府采取行动减少工厂和发电厂排放的二氧化碳量，攻击它的资源问题。他们都赞成把更多的资金用到研发太阳能、风能和波浪能装置上，以取代现有的发电站。
然而，还有一些科学家，他们相信即使明天我们不再排放二氧化碳和其他气体到大气层中，我们也将不得不等待几百年才能得到结果。全球变暖似乎要在这里停留。
