Climate scientists from the UK and across the world are in overwhelming agreement about the evidence of climate change, driven by the human input of greenhouse gases into the atmosphere.
消失的森林覆盖会加热地球，因为树木活着时会吸收CO2，当燃烧或被砍后，这些温室气体被重新释放到大气中。
Lost forest cover heats the planet, because trees absorb CO2 while they're alive - and when they're burned or cut down, the greenhouse gas is released back into the atmosphere.
