沙漠是地球上最荒凉的区域之一。为什么沙漠如此荒凉?按照我们一贯的理解是，沙漠地区缺乏生命所需的水，所以鲜有生命能在那些地区生存。最近，美国康奈尔大学的研究人员却发现，不少沙漠地区并非干得不能生长植物，而是肥力不够，因为沙漠土壤中缺乏植物赖以生存的氮。不过，令人担忧的是，随着气候不断变暖，沙漠地区土壤中含量可怜的氮还会不断挥发，以气体的形式大量流失，从而导致生长在沙漠里的植物越来越少。
研究人员在美国莫哈韦沙漠地区选了几处试验点，通过精密测量仪器了解土壤中的\'氮是如何随着气温升降而变化的。研究发现，不管有没有阳光照耀沙漠，当土壤温度达到40℃至50℃的高温时，土壤中的氮会以气体形式从土壤中迅速释放出来。而在沙漠中，地表温度达到40℃以上是轻而易举的事情。研究人员还发现，地表温度越高，沙漠土壤中释放氮的速度越快。因此，随着全球气候变暖的加剧，沙漠的气温和地表温度也将越来越高，土壤中的氮也将越来越少，沙漠会变得越来越荒凉和贫瘠。
研究人员还表示，除了沙漠地区，在世界任何高温干旱的地方都可能出现类似的情况。近年来让农林科研人员头疼的现象也由此找到了原因，他们在干旱地区种植实验田地，虽然保障了充分的水和肥料，但是土地的出产还是不尽如人意。
干旱地区的氮不但从土壤中偷偷溜走，而且很难再回到土壤之中。在气候温和地区，氮在土壤和大气中的循环是平衡的，当地土壤中的一部分氮虽然也会通过分解或植物收割流向大气;但是在雷雨天，空气中的氮气会在雷电的作用下变成氮肥回到土壤中。然而，干旱地区很少会有雷雨天气，也就很少会有氮再返回到土地中。正是因为干旱地区氮的流失是不可逆转的，我们花再大的代价，比如不计成本地往其中施放氮肥，也不可能让沙漠变成绿洲。除非，我们可以让沙漠地区的气温及地表温度降下来。
今天如果我们不能有效遏制气候变暖的发展趋势，代表着沙漠未来希望的零星绿色将越来越少，直至完全绝迹，沙漠的扩张也将变得气势汹汹而且肆无忌惮。那样令人绝望的未来，并非是我们所希望看到的!(选自《青年文摘》2010年第11期，有删改
