A rise of one degree per generation is a large in 4 . Nature seldom moves as swiftly as this. We may have been helping her. To a very large 5 , the temperature of the Earth is determined 6 the amount of solar heat which the atmosphere can keep.
The air above us sets like the glass in a greenhouse, trapping many of the heat waves which would other 7 bounce back into space. Carbon dioxide in the air is mostly responsible 8 the "greenhouse effect"; it is a gas produced by all our countless fires, furnaces (熔炉) and internal combustion engines (内燃机).
The end of the age of fossil fuels is already in sight; soon in one or two centuries at the roost we will have wasted all the world’s re 9 of oil and coal. This no longer means disaster, for 10 (atom) energy has arrived in time to save our civilization from dying through lack of power.
