04 Mar The IPCC Report
The IPCC Report – Today Current Affairs
Why in news?
The IPCC (Intergovernmental Panel on Climate Change) has analyzed and reviewed the present and future man-made impacts of climate change and has a message that is terrible in nature.
About the IPCC Reports: The Hindu Analysis
- The aim of the IPCC is to provide governments at all levels with the scientific information that they can use to develop climate policies and programs.
- The IPCC’s Assessment Reports are the most comprehensive evaluations of the state of the earth’s climate.
- The latest report talks about the impacts of climate change impacts,risks and vulnerabilities and adaptation options.
- For the first time, the IPCC report has highlighted the health impacts of climate change.
- It was identified that the rise in weather and climate extremes has led to some irreversible impacts as natural and human systems are pushed beyond their ability to adapt.
- Further it was noted that most of the targets that countries have set for themselves are too far in the future to have an impact in the short term.
Indian Case: The Hindu Analysis
- India’s assurance at the COP26 summit that it will achieve net zero emissions latest by 2070.
- And by 2030, India will ensure that 50% of its energy will be from renewable energy sources.
Specifications of the Reports: The Hindu Analysis
- The major point of emphasis of the report, particularly for South Asia, is the trend in the wet bulb temperature.
- Patna and Lucknow were among the cities predicted to reach wet-bulb temperatures of 35°C while Bhubaneshwar, Chennai, Mumbai, Indore, and Ahmedabad are at risk of reaching wet-bulb temperatures of 32°C-34°C with continued emissions.
- This will be having consequences such as a rise in heat-wave linked deaths or reduced productivity.
- The Global sea levels are likely to rise 44 to 76 cm in this century if governments match their current emission-cutting pledges.
- With the higher emissions, and if ice sheets collapse more quickly than expected, sea levels could rise as much as 2 metres in this century and 5 metres by 2150.
- By the mid of the century, approx 35 million people could face annual coastal flooding, with 45 million-50 million at risk by the end of the century if emissions are high.
- The Extreme weather led to cereal production loss of 9-10 % (1964-2007).
- The rice production in India may decrease by 30% and maize production will decrease 70%, if global warming over pre-industrial levels rises to 4°C from 1°C, the IPCC analysis found.
- The Evidence of floods on food production was limited, according to the report.
- The impact of drought on food security has been highlighted by the report but also cautioned that overall irrigation water demand would increase by 2080.
- The Fisheries, aquaculture and crop production, particularly in south and southeast Asia, may decline as a result of climate change.
- The Current global crop and livestock areas will increasingly become climatically unsuitable under a high emission scenario in major food-producing regions.
Today Current Affairs
Significance of the report: The Hindu Analysis
- The IPCC reports form the scientific basis on which countries across the world build their policy responses to climate change.
- These reports do not suggest to the countries or governments what to do and are only meant to present factual situations with scientific evidence.
- With respect to regional and sectoral impacts, Report presents actionable intelligence, particularly for countries that lack the resources or the capacity to make their own impact assessments.
- These findings are the product of the combined understanding of the largest group of experts on climate science that lends it credibility greater than any individual study.
- This report also forms the basis for international climate change negotiations that decide on the responses at the global level such as the Paris Agreement and Kyoto Protocol.
