This year's UN climate change conference, COP28, is being held in Dubai, from November 30 to December 12. For a long time, greenhouse gas emissions produced mainly by burning fossil fuels have raised the global temperature, aggravating climate change while extreme weather such as floods, droughts, hurricanes and wildfires have become normal. Catastrophes caused by climate change are warnings from nature to human beings. To tackle the climate change, joint efforts should be taken immediately.
