MY课题(全球气温变暖)

1、1为何选择此现象或问题进行调查，该问题或现象解决又有何实际意义或应用价值结果显而易见，全球变暖是不争的事实。这不仅仅是一个环境问题。它影响我们的公共健康和国家安全。这是一个紧迫的问题我们每个生存在这个星球上的人-最紧迫的当是如今人类所面临的威胁。这将采取行动，从你和我们大家的共同努力中。全球变暖不是主观臆断，它是科学事实，科学家告诉我们人类活动已经对我们赖以生存和生活安乐的星球产生巨大的影响世界领先的科技期刊报告说，冰川融化以十倍的速度上升可能超过先前预期，即大气中的温室气体已经达到的水平没有看到了数百万年之久，而且物种的消失是由于气候变化的影响。他们还报告了极端天气事件，长期干旱，海平面上升

2、。幸运的是，科学还告诉我们此刻我们还可以作出重大的弥补，试图扭转这些影响，但只有通过立即采取行动。这就是为什么我们研究这个课题希望大家一起加入遏制全球气温变暖行列。遏制全球变暖只是一个课题，但其目的却是真实的。希望通过众人的传播与身边的人们一起，迫使那些无意识的人们关注，团结起来为世界出一份力。地球作为一个生态系统正在发生变化，很大程度上的原因是在于全球化的影响和人为因素。更多的二氧化碳排放于大气层现在已经比过去六十五万年。这种碳在大气中停留，就像是温暖的毛毯，并拥有在热-因此得名全球变暖。 我们存在于这个星球上的原因，是因为地球的自然界提供我们足够热空气，其中的温度保持在一个非常狭窄的范围内

3、这创造了让我们可吸入的空气，干净的水，以及气候这一切决定了我们生存于此的条件。但是，这种平衡的打破已开始提示人类。我们超负荷的生产力大量的温室气体从我们的汽车，工厂和电厂被排向大气。如果我们不开始解决目前这一问题，我们正在对我们的环境做毁灭性的变化。我们将体验极端温度，海平面上升和风暴吹袭难以想象的破坏。最近，令人震惊的事件，是符合科学预测气候变化的影响的，这一切已经变得越来越普遍。正因为多数人都认为世界问题，环境问题与之无关。所以，当面对这一切的时候都处于漠然的态度。更多人却仍然毫无意识肆意的破坏着这已奄奄一息地我们赖以生存的地球。所以我们呼吁，身为当代大学生，受到各方面知识普及的我们，为我

4、们的地球献出一份爱。让我们站起来呼吁身边更多的人们为了世界，也为我们的未来伸出双手。3你们最后得出的结论是什么，有无达到预期效果？有何意义或启迪？你们有没有好的解决方案？出你的承诺，让我们一起熄灯一小时，为阻止全球气候变暖，尽一份应尽的职责2007年三月31日，悉尼号召当地人为“全球变暖问题”做出贡献。于是有220万居民和2100家企业参与到了这项“还给地球一小时”活动。2008年，又有24个城市加入这一活动。今年更有超过1000座城市和上百万人口承诺参加这个活动。 就在不久前2009年3月28日 19：3020：30 作出你的承诺，让我们一起熄灯一小时，为阻止全球气候变暖，尽一份应尽的职责。

5、我们也正为这全球变暖做着一份贡献，虽然只是短短的一小时却节省了 电，而 却可以产生 热。而我们要做的不只是一小时，是生活中的每一天每一刻。2你们是如何调查研究，采用何种方法，简单的说明调查研究的过程 04年6月11日在自然杂志上公布的一项研究结果表明,随着温室气体的增加,亚马逊雨林最深处的树种结构发生了显著的变化全球变暖可使热带雨林变草原雨林消失全球变暖导致花期提前动物北迁2004年11月11日发表于自然气候变暖导致真菌流行病蔓延2006年1月12日援引最新一期英国自然杂志发表Learn MoreThe results are in and the reality of global warm
