（B）
Is there link between humans and climatechange or not? This question was first studied in the early 1900s. Since then,many scientists have thought that our actions do make a difference. In 1997,the Kyoto Protocol explained our role in the Earth’s changing atmosphere andset international limits for gas emissions(排放) from 2008 to 2012. Somecountries have decided to continue these reductions until 2020. More recently,the Paris Agreement, stuck by nearly 200 countries, also aims to limit globalwarming. But just now how much warmer it will get depends on how deeplycountries cut carbon emissions.
70. It can be concluded from paragraph 1 that _______.
71. If nations could only keep the initial promises of the Paris Agreement, what would happen by the year 2100?
72. If those island nations not far above sea level are to survive, the maximum temperature rise, since the start of the industrial age, should be_______.
