50%怎么来的？

  1. ESG
  2. Environmental factors

NO.PZ2022120703000015

问题如下：

According to the Intergovernmental Panel on Climate Change (IPCC) in 2018, the most likely impact of 1.5°C (2.7°F) warming is that:

选项：

A.Arctic summer sea ice is likely to be maintained. B.the risk of an ice-free Arctic in summer is about 50% higher. C.Arctic summer sea ice will disappear.

解释：

A is correct?because a 1.5°C (2.7°F) rise in temperature could lead to "Arctic summer sea ice that is likely to be maintained."

B is incorrect because this is an impact of a 2°C (3.6°F) rise in temperature. "The risk of an ice-free Arctic in summer is about 50% or higher."

C is incorrect because this is an impact of a 3°C+ (5.4°F) rise in temperature. "The Arctic is very likely to be ice free in summer."

老师好，在经典题讲义相应的图中，没有看到50%，50%是怎么得出来的呢？

嗨，努力学习的PZer你好：


这个当成知识点补充吧，里面一些结论比较琐碎，辛苦同学记一下。
