This is the so-called greenhouse effect: the fact that the earth's atmosphere contains so-called greenhouse gases (of which water vapour is overwhelmingly the most important, but carbon dioxide is another) which, in effect, trap some of the heat we receive from the sun and prevent it from bouncing back into space.Nigel Lawson in his essay in Standpoint, 1 May
