近年来,地球气候异常,科学界普遍认为这是温室效应所致。温室效应是怎么回事呢?可以这样简单地说:地表温度的变化是阳光对大气层作用的结果,太阳的一部分光被大气层的云、雪、冰反射回太空,但绝大部分为地球吸收,转化为热量。地球的一部分热量从地表上升后穿过温室效应气体屏障,但其中部分热量因气体分子振荡而反射回地面,从而加剧了热效应(如图所示)。温室效应气体包括二氧化碳(50％),沼气(20％),氯氟碳(15％),笑气(10％)及臭氧(5％)。由于温室效应气体的主要成份是二氧化碳CO_2,因此CO_2愈多,
In recent years, the Earth’s climate anomalies, the scientific community generally think this is caused by the greenhouse effect. The greenhouse effect is how it can be said: the change in surface temperature is the result of the role of the sun on the atmosphere, part of the sun was the atmosphere of clouds, snow, ice reflected back to space, but most of the Earth’s absorption, Converted into heat. A portion of the Earth’s heat rises from the surface and across the greenhouse gas barrier, but some of the heat is reflected back into the ground due to gas molecular oscillations, exacerbating the thermal effects (as shown). Greenhouse gases include carbon dioxide (50%), biogas (20%), chlorofluorocarbons (15%), nitrous oxide (10%) and ozone (5%). As the main component of greenhouse gases is carbon dioxide CO_2, the more CO_2,
