According to a report by former World Bank chief economist Nicholas Stern, India is predicted to be severely affected by climate change, leading to poor agricultural output, more natural disasters, and increased fatalities from diseases. Stern warned that unchecked greenhouse gas emissions could result in a global temperature increase of 2-3 degrees centrigrade within the next 50 years. He also highlighted the potential impact on India's economy due to changes in the annual monsoon rains, which are crucial for crop production in the country. Stern mentioned the possibility of varying starting dates for the monsoon, more intense rainfall, and prolonged periods of drought. "It is probable that there will be disruptions," he stated. "It is evident that India will experience similar impacts as the rest of the world, possibly even more severe." Experts predict that a temperature increase of 2 to 3.5 degrees Celsius could result in India losing between nine to 25 percent of its agricultural revenue. Agriculture accounts for approximately 22 percent of India's GDP. Stern also mentioned that rising temperatures could lead to the spread of vector-borne diseases such as malaria and dengue fever to higher altitude areas that were previously mosquito-free. The head of Britain's Economic Service stated that the melting of Himalayan glaciers could lead to an increase in deaths, lower productivity, and serious floods in neighbouring Bangladesh due to rising sea levels. This could result in mass migration across the border into India, with the flow of water from the glaciers being reduced during India's dry season and causing significant consequences. Experts warn that the melting glaciers will impact one-sixth of the world's population in the Indian subcontinent, as the Ganga river relies on the Himalayan glaciers for 70 percent of its summer water flow and supports over 500 million people. Stern stated that India was making advancements in addressing emissions and investing in clean development mechanisms. He emphasized that climate change is unfair, with wealthy nations bearing the responsibility for 75 percent of greenhouse gases while poorer nations will suffer the most. He stressed that all countries should be involved in addressing climate change, but it is only fair for rich nations to bear the majority of the costs.
