B.
We have been producing too many of the gases which, when they are released into the earth’s atmosphere, trap heat, and thus raise their temperatures. There are several gases involved, but the main ones are carbon dioxide (二氧化碳) and chlorofluorocarbons (氯氟甲烷)--often called CFCs. The carbon dioxide comes from burning forests and from bunting fossil fuels such as oil and coal. The CFCs are given off by refrigerators and air-conditioning systems. Carbon dioxide is to blame for 56% of the greenhouse effect, and CFCs for 23%.
C.
The global warming we are experiencing now is only a result of the carbon dioxide and other gases we have dumped into the atmosphere up to the 1960s. In other words, the damage may have already been done. Temperatures are expected to increase by at least 1.3 Celsius degrees by 2030 and 3 degrees by the year 2070.
