New Delhi: Warning about the serious consequences of climate change, the United Nations in a report said that the average global temperature would rise by 3.2 degrees Celsius in the year 2100 even if all the current commitments mentioned in the Paris Agreement are implemented. The UN report was released on November 26 ahead of the 2019 United Nations Climate Change Conference (COP25), stated a report.

Earlier in 2018, the global greenhouse gas (GHG) emission was reported to have reached a new high with a record 55.3 gigatonnes of CO2 equivalent emissions reported in spite of “scientific warnings and political commitments”, added the UN report. Besides, an annual Emission Gap Report published by the UN Environment Programme noted an average annual increase of 1.5 per cent in GHG emissions over the last decade, stated a report.

The report added that the global goal of maintaining a 1.5 degree Celsius temperature rise is possible only if there is a 7.6 per cent annual decline in GHG emissions between the years 2020 and 2030. In order to achieve the 1.5 degree Celsius goal, all the nations have to cut their emissions levels by at least five-fold over the current levels, stated the UN report. Currently, nations all over the world are on track to a 2 degree Celsius temperature rise by reducing their emission levels three-fold, added the report.

According to the Emissions Gap report 2019, “The top four emitters (China, USA, EU28 and India) contribute to over 55 per cent of the total emissions over the last decade, excluding emissions from land-use change such as deforestation.” The UN report also mentioned that for ‘reasons of fairness and equity’, all the developed countries must achieve their short-term goal of cutting down emissions more quickly than the developing countries.
