According to an influential report on global warming by former World Bank chief economist Nicholas Stern, India is likely to face severe consequences of climate change, including reduced agricultural output, more frequent natural disasters, and an increase in deaths due to higher rates of diseases. Stern warned that if greenhouse gas emissions are not controlled, global temperatures could rise by 2-3 degrees Celsius in the next 50 years. Speaking to Indian business leaders, Stern highlighted the potential impact on India's economy, particularly on the crucial June-September monsoon rains that are essential for crop production. He mentioned the possibility of changes in the monsoon patterns, such as varying starting dates, increased intensity, and prolonged periods of drought. "He stated that there is a high probability of disruption. India is expected to face similar challenges as the rest of the world, and possibly even more severe ones. Experts predict that a temperature increase of 2 to 3.5 degrees Celsius could result in a loss of agricultural revenue ranging from nine to 25 percent for India. Agriculture accounts for approximately 22 percent of India's GDP. Additionally, rising temperatures could lead to the spread of vector-borne diseases such as malaria and dengue fever to higher altitude areas that are currently mosquito-free." The head of Britain's Economic Service stated that if the Himalayan glaciers continue to melt, there is a high possibility of increased deaths leading to decreased productivity. He also mentioned that this melting could cause severe floods in Bangladesh due to rising sea levels, prompting mass migration into India. Additionally, he warned that the reduced water flow from the glaciers during India's dry season would have significant repercussions. Experts predict that the melting glaciers will impact a large portion of the global population, particularly those in the Indian subcontinent, with India's Ganga river supporting over 500 million people by receiving 70 percent of its summer water flow from the Himalayan glaciers. Stern noted that India was making strides in addressing emissions challenges and investing in clean development methods. However, he emphasized that climate change disproportionately affects poorer nations, even though wealthier countries are responsible for the majority of greenhouse gas emissions. He stressed the importance of all countries participating in solutions, but also argued that rich nations should bear the majority of the financial burden.
