Climatic conditions are delicately
adjusted to the composition of the Earth’s atmosphere. If there were a change in
the atmosphere for example, in the relative proportions of atmosphere gases the
climate would probably change also. A slight increase in water vapor, for
instance, would increase the heat-retaining capacity of the atmosphere and would
lead to a rise in global temperatures. In contrast, a large increase in
water vapor would increase the thickness and extent of the cloud layer, reducing
the amount of solar energy reaching the Earth’s surface. The level of carbon dioxide, CO2, in the atmosphere has an important effect on climatic change. Most of the Earth’s incoming energy is short wavelength radiation, which tends to pass through atmospheric CO2 easily. The Earth, however, reradiates much of the A. explaining the effects that the burning of fossil fuels might have on climate B. illustrating the effects of CO2 on atmospheric radiation C. discussing effects that changes in the CO2 level in the atmosphere might have on climate D. challenging hypotheses about the effects of water vapor and CO2 on climate [单项选择]选用于缓慢型心律失常的药物是()。
