During the Triassic period of 251–199.6 Ma, the Indian subcontinent was the part of a vast supercontinent known as Pangaea.Despite its position within a high-latitude belt at 55–75° S—latitudes now occupied by parts of the Antarctic Peninsula, as opposed to India's current position between 8 and 37° N—India likely experienced a humid temperate climate with warm and frost-free weather ...
By the year 2050, India is expected to witness a significant increase in climate-related displacement, with around 45 million people compelled to migrate from their homes due to climate disasters. This number is three times higher than the current count of individuals being displaced because of extreme weather events.
The climate of India comprises a wide range of weather conditions across a vast geographic scale and varied topography, making generalisations difficult. Based on the Köppen system, India hosts six major climatic subtypes, ranging from arid desert in the west, alpine tundra and glaciers in the north, and humid tropical regions supporting rainforests in the southwest and the island territories.
India's weather agency makes state-level monsoon rain predictions for the entire country, but climate experts say forecasts need to be more localized in order to be useful to farmers.
However, India was the third largest emitter of total carbon dioxide in 2009 at 1.65 Gt per year, after China (6.9 Gt per year) and the United States (5.2 Gt per year). With 17 percent of world population, India contributed some 5 percent of human-sourced carbon dioxide emission; compared to China's 24 percent share. [35] [36]
At 4 °C an extremely wet monsoon which currently has a 1 in 100 year's chance will occur in every 10 years by 2100. Extremes in maximum and minimum temperatures and precipitation will increase particularly over western coast and central and north-east India. [19] The dry years are expected to be drier and wet years wetter due to Climate Change.
The climate comprises a wide range of weather conditions across a vast geographic scale and varied topography, making generalisations difficult. Given the size of India with the Himalayas, Arabian Sea, Bay of Bengal and the Indian Ocean, there is a great variation in temperature and precipitation distribution in the subcontinent. [ 15 ]
A visualisation of the South Asian Monsoon based on the Climate Hazards Group InfraRed Precipitation with Station data (CHIRPS) 30+ year quasi-global rainfall dataset, analysed and visualised using Google Earth Engine. Annual average monsoon precipitation in India over 110 years. The long-term average has been 899 millimeters of precipitation. [1]
