Intergovernmental Panel on Climate Change (IPCC)
Part of: Prelims and GS-III Environment
Context: According to a report by the Intergovernmental Panel on Climate Change (IPCC), the world faces unavoidable multiple climate hazards over the next two decades with global warming of 1.5°C.
- Even temporarily exceeding this warming level would mean additional, severe impacts, some of which will be irreversible.
Key highlights of the report
- Human-induced climate change, including more frequent and intense extreme events, has caused widespread adverse impacts and damage to nature and people.
- Some development and adaptation efforts have reduced vulnerability.
- Across sectors and regions, the most vulnerable people and systems are observed to be disproportionately affected.
- The rise in weather and climate extremes have led to some irreversible impacts as natural and human systems are pushed beyond their ability to adapt.
- Wet bulb temperature is the lowest temperature to which air can be cooled by the evaporation of water into the air at a constant pressure.
- According to the report, Lucknow and Patna are among the cities predicted to reach wet-bulb temperature of 35°C if emissions continued to rise.
- Bhubaneswar, Chennai, Mumbai, Indore, and Ahmedabad are identified as at risk of reaching wet-bulb temperatures of 32-34°C with continued emissions.
- Overall, Assam, Meghalaya, Tripura, West Bengal, Bihar, Jharkhand, Odisha, Chhattisgarh, Uttar Pradesh, Haryana and Punjab will be the most severely affected.
- But if emissions keep rising, all States will have regions that experience wet-bulb temperatures of 30°C or more by the end of the century.
What is Intergovernmental Panel on Climate Change (IPCC)?
- It is an international body set up in 1988 by the World Meteorological Organization (WMO) and United Nations Environment Programme (UNEP) to provide policymakers with
- Regular assessments of the scientific basis of climate change
- Impacts and future risks associated with Climate Change
- Options for adaptation and mitigation for Climate Change
- Membership of the IPCC is open to all members of the WMO and the UNEP.
- IPCC assessments provide a scientific basis for governments at all levels to develop climate-related policies and also underlie climate negotiation at International level.
- The main objective of UNFCCC is to stabilize greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system.
