The IPCC released the second part of the sixth assessment report on Monday. This is related to the effects of climate change, risk and vulnerability, and adaptation measures. For the first time, the panel has come out with regional assessments, even focusing on major cities, in its report. India is one of the most vulnerable countries globally in terms of populations that will be influenced by sea level rise, IPCC reports.
Extreme heat including heatwave has increased in cities, where they also worsen air pollution events and limited functions of the main infrastructure, “report notes.” The observed impact is concentrated among urban residents who are economically mariced and socially, including transportation, water , sanitation and energy systems have been compromised by extreme events and slow onset, by generating economic losses, service disorders and impacts on well-being. “
“Globally, heat and moisture will create conditions beyond human tolerance if emissions are not quickly eliminated; India is one of the places that will experience this condition that cannot be tolerated,” he said.
Prof. Anjal Prakash, one of the main writers in the chapter in the city, settlement and the main infrastructure in the report, said: “Indian urban risks greater than other regions with a projected population of 877 million in 2050, almost 480 million. By 2020 . At present, urbanization in this country is at 35 percent, which is likely to increase to 40 percent in the next 15 years. Big cities grow faster, and even smaller centers grow quickly. Only the population concentration in the city -The city makes this settlement very susceptible to climate change. “
The report refers to wet-wet temperatures, sizes that combine heat and moisture. The temperature of wet-wet 31 degrees Celsius is very dangerous for humans, while the value of 35 degrees cannot be carried out more than about six hours, even for adults who are fit and healthy.
At present, the temperature of wet-wet in India rarely exceeds 31 degrees C, with most countries experiencing a maximum wet bulb temperature of 25-30 degrees C, according to IPCC. It notes that if the emissions are cut, but only by the current level are promised, many parts in North India and the coast will reach wet bulb temperatures that are very dangerous than more than 31 degrees C towards the end of this century. If emissions continue to increase, the temperature of the wet bulb will approach or exceed the limit of 35 degrees C compared to most India, with the majority of countries reaching a wet bulb temperature of 31 degrees C or more.
