Since the industrial revolution,carbon dioxide concentration in the atmosphere has risen sharply due to the widely-used fossil fuel,leading to global warming and frequent extreme climate events.To effectively confront and mitigate the climate change,in the Paris Agreement,the international community set warming targets to hold the increase in the global average temperature to well below 2 ℃ above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5 ℃ above pre-industrial levels.The concept of carbon neutrality starts spreading and known by larger communities.Here,we introduced some basic facts of global warming and the effect of anthropogenic carbon emission on the warming,summarized main results with respect to future climate changes,elucidated the relationship between 1.5/2 ℃ warming threshold and the carbon neutral,and finally overviewed the efforts of carbon reduction made by international community to effectively adapt to and mitigate the global warming.
