IPCC panel study prescribes ‘large-scale changes’ to keep the rise in global temperature below 1.5°C
If the average global temperature rises by more than one degree Celsius from the present, India could “annually” expect conditions like the 2015 heat wave that killed at least 2,000, according to the ‘Special Report on Global Warming of 1.5°C,’ commissioned by the Intergovernmental Panel on Climate Change (IPCC). The report was put together by about 91 authors and review-editors from 40 countries, who had convened in Incheon, South Korea, last week, to assess the feasibility of keeping the average global temperature from rising beyond 1.5 degree Celsius from pre-industrial times. Achieving this would require “rapid, far-reaching and unprecedented changes in all aspects of society,” the IPCC said in the assessment. The 2015 agreement in Paris, considered a landmark achievement, had the world agree to keep temperatures below 2 degrees Celsius and “pursue efforts to limit the temperature increase to 1.5°C above pre-industrial levels.”
With the U.S. withdrawing from the accord, the chances of such an ambitious target were significantly weakened. “Limiting global warming to 1.5°C, compared with 2°C, would reduce challenging impacts on ecosystems, human health and well-being, making it easier to achieve the United Nations Sustainable Development Goals,” Priyardarshi Shukla, Co-Chair of IPCC Working Group III, said in a statement. A representative of the Indian delegation told The Hindu that much of the discussion centred on government officials questioning the authors on the scientific basis of their assessment. “An earlier draft said there was ‘high confidence’ of the extent of changes to the Indian monsoon. This subsequently became ‘medium confidence’,” said the official, who didn’t want to be identified. The U.S. has “rejected” the findings of this report, the official added. Officials of the Environment Ministry, the Ministry of Earth Sciences, the Indian Institute of Human Settlements, and the Tata Institute of Social Sciences were part of the Indian delegation.
