New Climate Report

In News 
  • The latest report of the Intergovernmental Panel on Climate Change (IPCC), released,has warned of multiple climate change-induced disasters in the next two decades even if strong action is taken to reduce the emissions of greenhouse gas emissions.
Details 
  • It has said the ability of human beings, and natural systems, to cope with the changing climate was already being tested, and further rise in global warming would make it even more difficult to adapt.
  • Noting that over 3.5 billion people, over 45% of the global population, were living in areas highly vulnerable to climate change, the report identifies India as one of the vulnerable hotspots, with several regions and important cities facing very high risk of climate disasters such as flooding, sea-level rise and heat-waves.
  • The Assessment Reports, the first of which had come out in 1990, are the most comprehensive evaluations of the state of the earth’s climate.
  • Hundreds of experts go through every available piece of relevant, published scientific information to prepare a common understanding of the changing climate.
  • The four subsequent assessment reports, each thousands of pages long, came out in 1995, 2001, 2007 and 2015. These have formed the basis of the global response to climate change.

Impact on India 
  • The latest report has, for the first time, made an assessment of regional and sectoral impacts of climate change.
  • It has included risks to, and vulnerabilities of, mega-cities around the world.
  • For example, it has said Mumbai is at high risk of sea-level rise and flooding, while Ahmedabad faces serious danger of heat-waves.
  • Such granular information was not available in previous assessment reports. Flooding in Mumbai and heat-waves in Ahmedabad are common occurrences. 
  • The first time, the IPCC report has looked at the health impacts of climate change.
  • It has found that climate change is increasing vector-borne and water-borne diseases such as malaria or dengue, particularly in sub-tropical regions of Asia.
  • It has also said deaths related to circulatory, respiratory, diabetic and infectious diseases, as well as infant mortality, are likely to increase with a rise in temperature.
  • Increasing frequency of extreme weather events like heatwaves, flooding and drought, and even air pollution was contributing to under-nutrition, allergic diseases and even mental disorders.
