The current concentration of carbon dioxide in the atmosphere is about 360 parts per million.
Human activities are having a major influence on atmospheric carbon dioxide concentrations, which are rising so fast that current predictions are that atmospheric concentrations of carbon dioxide will double in the next 50 to 100 years.
The Intergovernmental Panel on Climate Change(IPCC)report in 1992, which represents a
consensus
of most atmospheric scientists, predicts that a doubling of carbon dioxide concentration would raise global temperatures anywhere between 1.4°C and 4.5°C. The IPCC report issued in 2001 raised the temperature prediction almost twofold. The suggested rise in temperature is greater than the changes that occurred in the past between ice ages. The increase in temperatures would not be uniform, with the smallest changes at the equator and changes two or three times as great at the poles. The local effects of these global changes are difficult to predict, but it is generally agreed that they may include alterations in ocean currents, increased winter flooding in some areas of the Northern Hemisphere, a higher incidence of summer drought in some areas, and rising sea levels, which may flood low-lying countries. [br] According to paragraph 2, what can be said about the effects of global changes?
选项
A、The local plants and animals will be permanently damaged.
B、It is hard to know exactly what form the local effects will take.
C、Seawater levels will fall around the world.
D、The effects will not occur in some regions of the world.
答案
