在第一個版本時，專家們認為因人為活動導致全球暖化的機率大約只有3成，但後續的研究卻證明，人類活動對氣候系統造成影響的機率恐怕相當高，科學家們評估的機率由第1版的33％，陸續提高到50％、66％，在2013年發表的第5版報告中，評估出來的機率已經高達99％。由此可見人類一定要具體且持續地減少溫室氣體的排放，才能減緩氣候改變。

結果 (英文) 1:

When the first version, the experts believe that the chances of global warming caused by human activity leads to only about 3 percent, but subsequent studies have shown that the probability of the impact of human activities on the climate system is probably very high, scientists assess the probability of 33% of the first edition, gradually increased to 50%, 66%, in the fifth edition of the report published in 2013, has been out to assess the probability of up to 99%. This shows that human beings must be specific and sustained reductions in greenhouse gas emissions to mitigate climate change.

結果 (英文) 2:

In the first edition, experts believed that the probability of global warming due to man-made activities was only about 30%, but subsequent studies showed that the chances of human activity affecting the climate system were probably quite high, with scientists assessing the probability of increasing from 33% in the first edition to 50%, 66%. In the 5th edition of the report, published in 2013, the probability of being assessed was as high as 99%. This shows that human beings must reduce greenhouse gas emissions specifically and continuously in order to slow climate change.

In the first version, experts thought that the probability of global warming caused by human activities was only about 30%. However, subsequent studies have proved that the probability of human activities affecting the climate system may be quite high. The probability of scientists' assessment has increased from 33% in the first version to 50% and 66% in succession. In the fifth version of the report published in 2013, the probability of assessment has reached 99% %It can be seen that human beings must reduce greenhouse gas emissions concretely and continuously in order to slow down climate change.
