Over 60 crore people would be exposed to dangerous heat

In News
  • More than 200 crore people worldwide, including over 60 crore in India, would be exposed to dangerously hot temperatures even if all countries meet their promised emission cuts, a new research says.
Highlights of the study
  • The lifetime emissions of 3.5 average global citizens today - or just 1.2 US citizens -expose one future person to dangerous heat, highlighting the inequity of the climate crisis as these future heat-exposed people will live in places where emissions today are around a half of the global average.
  • The study reveals that by the end of the century, the average global temperatures are expected to rise by 2.7C.
  • The study highlights several countries that will fall into the extreme heat zone.
  • Burkina Faso, Mali, Qatar, Aruba, and the United Arab Emirates are among the nations projected to experience high temperatures outside the human niche.
  • In terms of the number of affected inhabitants, India, Nigeria, and Indonesia are anticipated to bear the brunt of the heat crisis.
  • Disturbingly, it is estimated that 600 million individuals in India, 300 million in Nigeria, and 100 million in Indonesia will fall out of the human niche later in this century.
  • If global warming can be limited to 1.5C through substantial reductions in greenhouse gas emissions, the number of people affected by dangerous heat in India, Nigeria, and Indonesia can be significantly reduced.
  • In this scenario, projections estimate that 90 million individuals in India, 40 million in Nigeria, and 5 million in Indonesia would be spared from the perils of extreme heat.
