The Effects of Global Warming on Weather

There are hidden factors which scientists call "feedback mechanisms”。 No one knows quite how they will interact with the changing 's one example： plants and animals adapt to climate change over the current estimate of half a degree centigrade of warming per decade,vegetation (植物) may not keep atologist James Hansen predicts climate zones will shift toward the poles by 50 to 75 kilometres a year—faster than trees can naturally ies that find themselves in an unfamiliar environment will 1000-kilometer-wide strip of forest running through Canada,the USSR and Scandinavia could be cut by ions of dying trees would soon lead to massive forest fires,releasing tons of CO2 and further boosting global warming.

There are dozens of other possible "feedback mechanism”。 Higher temperatures will fuel condensation and increase cloudiness,which may actually damp down global rs,like the "albedo"effect,will do the "albedo"effect is the amount of solar energy reflected by the earth's northern ice and snow melts and the darker sea and land pokes (戳) through,more heat will be absorbed,adding to the global temperature increase.

Even if we were to magically stop all greenhouse-gas emissions tomorrow the impact on global climate would continue for y will simply make the problem fact is that some of us are doing quite well the way things developed world prosperity has been built on 150 years of cheap fossil fuels.

Material progress has been linked to energy y 75 percent of all the world's energy is consumed by a quarter of the world's average rich-world resident adds about 3.2 tons of CO2 yearly to the atmosphere,more than four times the level added by each Third World US,with just seven per cent of the global population,is responsible for 22 per cent of global warming.

41."Feedback mechanisms"in paragraph 1 most probably refer to ____________.

plants and animals adapt to hidden factors

plants and animals interact with the changing climate

climate changes

climate zones shift

can learn from the passage that ____________.

feedback mechanisms may slow down global warming

basic facts of global warming are unknown

loping countries benefit from cheap fossil fuels

loped countries have decided to reduce their energy consumption

s Hansen predicts that the shift of climate zones will be accompanied by ____________.

cutting of many trees

rable environmental changes

essful migration of species

ccessful migration of trees

can be inferred from the passage that ____________.

developing world has decided to increase its energy consumption

B.a third-world citizen adds less than a ton of CO2 yearly to the atmosphere

world climate would soon gain its balance if we stopped greenhouse gas emissions

re prosperity of the world is dependent on cheap fossil fuels

h of the following is the main topic of the passage?____________

ct of global warming on climate.

perity and cheap fossil fuels.

rial progress and energy consumption.

ts and animals in the changing climate.
