hing at a tim 6 从迈阿密到希什玛瑞夫，以及这两地之间的许多地方，人们都说气候看起来不再正常了。但客观地说，本来就没有正常气候这回事。正如美国中西部农民常说的，\如果你不喜欢这天气，只需等五分钟。\很少有正常季节。有些年份冬季的降雪量和夏季的热浪打破了平均水平，而另一些年份则低于平均水平。面对这些自然波动，想看出气候总的变化，很难。例如，一年甚至连续三年异乎寻常地炎热并不一定意味着总的趋势出现了显著的变化。
7 然而，地球上的气候确实不断变化。在冰期地球连续好几万年都冻住，暖热期则把热带地区大大推进到现在的温带。但是，考虑到每年都有的正常变化，能显示这种可能在

1你认为自己对全球气候变暖持怀疑态度？也许你并非住在墨西哥湾沿岸的佛罗里达州，也非住在阿拉斯加州的希什玛瑞夫。居住在那些地区的人们普遍相信全球气候在变暖。2004年佛罗里达遭受四次威力无比的飓风袭击，一年后卡特里娜飓风淹没了新奥尔良并重创密西西比州的沿海地区。许多科学家认为,过去几个飓风季节的特大威力应归咎于全球气候变暖。大风暴增加了墨西哥湾暖流的热量，那些纬度地区正在逐年变暖。

hing at a14 一些科学家不仅仅在研究气候变化，而且还在研究气候突然变化这种甚至更加骇人的现象。大家知道,像大气这样的复杂系统从一种稳定状态转到另一种状态，其间只有非常短暂的过渡期。（就说水吧：把水放在火焰上方时，水会越烧越热，直到突然变成蒸汽。）由宾夕法尼亚州立大学地球科学家理查德·阿莱在20世纪90年代从格陵兰岛取回的冰核显示，上一次冰期不是在地质时间缓慢进行中结束的，而是在现实时间快速变化中结束的，整个地球在短短三年内便突然变暖了。
15 类似这样的研究也许还不足以令怀疑全球气候变暖的人信服。但似乎完全可以肯定的
time and13\毫无疑问，气候在发生变化，对此人类要负一部分责任，\科罗拉多州博耳德的国家大气研究中心气候分析部主任凯文·特伦泊斯对《时代》杂志如是说。\气候朝着可能会有更多强风暴和更大降雨量的方向变化。\国家大气研究中心气象学家格雷格·霍蓝德说:\这些不是小变化。我们是在谈论一场非常大的变化。\
All thin12 公共卫生会遭受损害。上升的海平面让盐污染淡水供应。强阳光和暖气候会令城市臭氧含量增高从而加剧呼吸系统疾病。暖气候会扩大携带疾病的啮齿目动物和诸如蚊子壁虱等虫子的活动范围，因而提高登革热、疟疾、脑炎、莱姆病（关节炎）和其它疾病的发生率。人们，尤其是较贫穷国家的人们，要适应变化将会碰到许多困难，但是对于野生动植物来说，这种变化的后果会是毁灭性的。
gs in11如果气温上升幅度大到一定程度，后果会是灾难性的。倘若海平面上升高达3英尺，大片人口稠密的地区——佛罗里达州沿海地区、路易斯安那州大部分地方、尼罗河三角洲、马尔代夫、孟加拉国——将无法居住。整个气候带可能会明显移动，使加拿大中部看上去更像伊利诺斯州中部，佐治亚州更像危地马拉。农业将陷入混乱状态。千百万人将被迫从无法居住的地区迁走。
their be10 面对这些确凿的事实，多数科学家不再怀疑全球正在变暖，而且几乎没有人质疑人类对此至少负一部分责任。变化还没有结束。与工业化以前水平相比，人类已将二氧化碳这一大气中最多的聚集热量的气体的浓度提高了30% ——百分比每年都在增长。显而易见的结论是：气温将继续上升。
ing ar9 如今再也不是那样了。来自受人尊重的科学机构的报告、研究和文章业已表明，过去一个世纪里世界范围的气温上升了华氏1度多，20世纪90年代是有史以来最热的十年。请朝四周看看：雪原,包括遐尔闻名的乞力马扎罗雪山的积雪，正从全球山顶上消失。随着大海变得太热,再无舒适可言，珊瑚礁正在相继死去。干旱在亚洲和非洲的部分地区已成为常态。引发东太平洋灾难性气候的厄尔尼诺现象更加频繁出现。北极的永久冻土开始解冻。寒冷地区的江河湖泊每年结冰推迟，解冻提早。动植物把它们的生长区向极地和高地移动，种类迥异的动物如北极熊、蝴蝶和白鲸，其迁徙方式正被搅乱。
e good for8 这就是正在发生的事情。1988年，当《时代》杂志把地球命名为年度之星球时，关于世界因人类活动而变暖的想法很大程度上仅存在于理论上。我们知道，自18世纪工业革命开始以来，工厂、发电厂、汽车和农场一直把聚集热量的气体排入大气层中。但气候确实在变热的证据当时依然不明显。
