Annual rainfall and droughts are going to increase as expected by India’s first-ever national forecast on the impact of global warming on the Indian subcontinent.
All these predictions are based on the climate forecasting model developed by the Indian Institute of Tropical Meteorology (IITM), Pune, and it will be a part of the next report of the Intergovernmental Panel on Climate Change (IPCC), expected to be ready by 2022.
From 1986-2015, the hottest day and coldest night have warmed 0.63°C and 0.4°C, respectively. If we consider a hypothetical scenario where no steps are taken to control global greenhouse gas emissions (which is called RCP8.5) then, according to a report, by the end of the 21st century the hottest day and coldest night would have a rise of approximately 4.7°C and 5.5°C, respectively, relative to the corresponding temperatures in 1976-2005.
The number of hot days and hot nights are going to increase by 55% and 70%, respectively, relative to the reference period of 1976-2005. Summer heatwaves over India are going to be three to four times higher by the end of the 21st century.
The report also mentions that these grating climatic conditions are going to affect agricultural activities, ecosystems, and freshwater resources. An increase in fossil fuel burning, use of fertilizer as well as natural processes have increased the concentration of hazardous substances in our environment in recent few decades.
It’s high time, we must put a bar to climatic changes, as these adversely affect our environment. Save our planet as life on other planets is still a question.
