Climate change could increase the frequency of heat waves in South Asia by 30 times

Accordingly, Climate Change can cause the frequency of episodes hot in India and Pakistan in March and April increased by 30 times.

According to senior researcher Friederike Otto of the Grantham Institute, Imperial College London, before humans caused climate change, such weather changes only happened once in about 3,000 years. She and researchers from the Global Weather Organization (WWA) said that the time period in which global temperatures increased by 1.2^oC has been shortened, with the same frequency and intensity as in South Asia to 100 years, and confirms that, as the Earth continues to warm, the time between such extreme heat waves will continue to shrink. short.

If Earth’s temperature increase by 1.6^oC compared to pre-industrial temperatures, such a hot event will happen once every 5 years. The 2 . increase in Earth’s temperature^oC is a worrying scenario. Countries have now committed to reducing greenhouse gas emissions in the Paris Agreement on climate change, which limits the increase in Earth’s temperature to 2.8^oC.

In South Asian countries like India and Pakistan, the hottest time is during March and April. Therefore, it takes months to calculate the life and health effects of the weather phenomenon. these extremes, including hospital stays, reduced wages, absences from school, and reduced working hours. Currently at least 90 people have died from heat in these two countries, but the actual number is thought to be much higher, up to thousands.

Referring to the Paris Agreement on climate change’s goal of controlling global temperature rise, the report said: “It is conceivable how bad it would be even if the world only warm up 1.5^oC”. Therefore, if the global temperature increases by 1.5^oC will pose a serious threat to vulnerable people due to lack of access to cooling and temperature reduction measures.
