However,the atmosphere is not quite as transparent to infrared radiation as it is to visible light,Carbon dioxide in particular tends to block such radiation.Less heat is lost at night,for that reason,than would be lost if carbon dioxide were not present in the atmosphere.Without the small quantity of that gas present,the Earth would be distinctly cooler,perhaps uncomfortably cool.
但是,大气层对红外射线来说,不象对常人可见的光线一样的透明。尤其是二氧化碳,会阻碍这些射线的通过。正因为如此,如果在晚上没有二氧化碳,那么热量的消逝会更多些。如果没有少量的二氧化碳的存在,地球将会明显的变冷,也许是冷到令人不适的地步。
不过,气氛是不太透明,以红外辐射,因为它是可见光,二氧化碳,特别是往往座等radiation.less热是失去了在夜间,由于这个原因,超过将失去,如果二氧化碳的不在场在atmosphere.without少量气体,目前地球将明显较凉,也许令人不安的冷静。
