UN report: India to face deadly heatwaves with just 2 degree C warming
IPCC says avoiding global climate chaos will require a major change of society and world economy
India could witness deadly heatwaves if the planet's temperature goes up by two degrees Celsius, according to a report released on Monday by the UN's Intergovernmental Panel for Climate Change (IPCC). "At +2°C warming, Karachi and Kolkata could expect annual conditions equivalent to their deadly 2015 heatwaves (medium confidence)," the report said.
Avoiding global climate chaos will require a major change of society and the world economy that is "unprecedented in scale," the IPCC said in the report that warns time is running out to avert disaster. "At +1.5°C, twice as many megacities as present such as Lagos in Nigeria and Shanghai in China are likely to become heat stressed, potentially exposing more than 350 million more people to deadly heat stress by 2050," the report further adds.

It says regionally differentiated multi-sector risks are apparent at 1.5°C warming, in South Asia — mostly Pakistan, India and China, but these will spread to sub-Saharan Africa, Middle East and East Asia as temperature rises.

What the report says
. Regionally differentiated multi-sector risks are apparent at 1.5°C warming, mainly in South Asia — mostly Pakistan, India, and China, but these will spread to sub-Saharan Africa, the Middle East and East Asia as temperature rises
. Although warming is projected to be the highest in the Northern Hemisphere under 1.5ºC or 2°C of global warming, regions in the tropics and Southern Hemisphere subtropics have been projected to experience the largest impacts on economic growth
. Risks are projected to be highest in south and south-east Asia, assuming there is no upgrade to present protection levels, for all temperatures of climate warming
