text: In the past hundred years, the global climate has experienced great changes1–4. According to the sixth assess- 
  ment report of IPCC, the global average surface temperature increased by 1.09 °C between 1850 and 2020, and 
  almost all regions in the world experienced surface warming5. Due to global warming, the extreme climate events 
  become more and more frequent, and the ecological environment problems caused by climate change are more 
  and more serious, which restrict the sustainable development of human society and health6–10. Global warming 
  has gradually changed from a scientific issue to a major social issue of common concern to governments and 
  people of all countries11–13. In 2016, nearly 200 parties of the United Nations Framework Convention on climate 
  change reached the Paris Agreement at the climate change conference in Paris14. Paris Agreement has indicated 
  that it is urgent to hold the increase in global average temperature well below 2.0 °C above pre-industrial levels 
  and pursue efforts to limit the temperature increase to 1.5 °C above pre-industrial levels.
