COP-27: Payback time for rich nations
At the ongoing COP 27 at Sharm El-Sheikh in Egypt, the IPCC has made it clear that climate catastrophe is unfolding. Global warming has already touched 1.1 degrees Celsius and extreme weather events are becoming more frequent and severe. The current commitments and policies of different nations will lead to a temperature rise of 2.8 degrees by the end of this century. The window of opportunity to restrict global warming to 1.5 degrees seems to be closing rapidly. To avert this, carbon emissions must come down 45 per cent by 2030 and touch net zero by 2050.
