地球冷暖的变化主要是因为大气中阳光的彩响,云、雪和冰可把部分阳光反射到宇宙空间,而地球艰收大量阳光,并将其转化为红外能——热辐射.由于来自地球表面的热辐射上升,它遇到二氧化碳和其它气体分子并使其振动.这些气体分子把部分热辐射反射到地球,加剧变暖效应.(坦率地说,有实例表明这些气体在大气层中已成为一个带;实际上它们到处出现). The main reason for the change in the earth’s warmth is that the clouds, snow, and ice in the atmosphere reflect part of the sunlight into the universe, and the Earth is suffering a lot of sunshine and convert it into infrared energy - heat radiation. Surface heat radiation rises and it encounters and vibrates carbon dioxide and other gas molecules, which reflect part of the heat radiation to Earth, intensifying the warming effect (to be fair, examples show that these gases have become A band; in fact they appear everywhere).
