Given the steady rise in global and Indian temperatures since 2010, and the increasing El Nino effect, 2023 will also be a year of heat waves and extreme temperature rise.
There were numerous heat waves in the months of March, April, May, and June of 2022. Gujrat, Rajasthan experienced heat waves on March 29, 30, and 31. Heat waves occurred in Gujrat on the 1st and 2nd of April, as well as in Vidarbha between the 26th and 30th of April. In addition, a heat wave was observed in Vidarbha from the 8th to the 15th of May and from the 3rd to the 7th of June. Temperatures in many Maharashtra cities reached 45 degrees, while in Chandrapur, it reached 46.8 degrees. Summer has 30 days of extreme temperatures and heat waves. The above-mentioned record spans the last 50 years.
Global warming and heat waves are caused by increasing deforestation, urbanisation, industrialization, pollution, and atmospheric carbon di-oxide levels (420ppm).
El Nino’s effect :
La Nina was in effect from 2020 to 2022. As a result, the country got good rains but the normal (neutral) condition has come in the beginning of 2023 and the influence of El Nino will increase further, NASA, World Meteorological Department and other meteorological institutes have announced after the study. El Nino is likely to contribute to the rise in summer temperatures. If this occurs, the year 2023 is also likely to be one of extreme temperatures.
