That scenario foresees Earth's average surface temperature rising 3.3 degrees Celsius above the preindustrial benchmark.

科学家预测，到那时地球的平均表面温度将比工业化前基准水平高出3。3摄氏度。

And this is happening at 1.2 degrees Celsius of global mean surface temperature rise.

而这发生在全球平均地表温度上升1.2摄氏度的情况下。

We are at 1.2 degrees Celsius of global mean surface temperature rise and 17 percent of deforestation.

全球平均地表温度上升了 1.2 摄氏度，森林砍伐率上升了 17%。

We've reached 1.2 degree Celsius of global mean surface temperature rise, the warmest temperature on Earth over the past 100,000 years.

全球平均地表温度已上升至 1.2 摄氏度，这是过去 10 万年来地球的最高温度。

Let's go to the Amazon basin, again, the richest terrestrial ecosystem on land, climate science estimates the risk of the Amazon rainforest tipping over irreversibly to a savanna at three to five degrees of global mean surface temperature rise.

我们再来看看亚马逊盆地，这里是陆地上最丰富的生态系统，气候科学估计， 当全球平均地表温度上升 3 至 5 度时， 亚马逊雨林就有不可逆转地变成稀树草原的风险。
