A warmer world could see the mosquitoes that carry diseases such as malaria17 and dengue fever expand across a wider range. But 2°C would also see a bigger share of insects and animals lose most of their habitat range, compared with 1.5°C, and increase the risk of forest fires - another risk to wildlife.

全球变暖会导致携带疟疾和登革热病毒的蚊虫大范围滋生。相比升温1.5摄氏度，升温2摄氏度会让更多昆虫和动物失去大部分栖息地，还会增加森林火灾风险，进而危及野生动植物的生存。

As the world heats up, the risk increases that the planet will reach "tipping points", where Earth’s systems cross a threshold that triggers irreversible or cascading18 impacts. Exactly when those points would be reached is uncertain.

随着全球变暖，地球达到“临界点”的风险也会增加。一旦到达这个临界点，就会触发地球系统不可逆转的连锁效应。但是具体何时到达临界点还不确定。

Droughts, reduced rainfall, and continued destruction of the Amazon through deforestation, for example, could see the rainforest system collapse, releasing CO2 into the atmosphere rather than storing it. Or warming Arctic permafrost could cause long-frozen biomass to decompose19, releasing vast amo
