I am quite sick and tired of this weather right now and I’m sure you are feeling this as well. The World Bank Group has figured out some of the common signs of this present weather. The first common sign that they have indicated is extreme heat. Thus, it can be expected that under 4 degrees Celsius warming, the southern India and West coast areas are projected to shift to high-temperature climate regimes. At the same time, unusual spells of extreme heat can be experienced soon. Another very common sign of climate change is the frequency of heavy rainfall events. Hence, the unpredictability of the summer monsoon can be the reason for frequent droughts and floods in larger parts of India. The areas that could largely be affected by droughts include Orissa, North Western India, and Chhattisgarh. So the crop areas of India will be the biggest victim of climate change. In Kolkata(0.5°C & 0.2°C) got way too warmer in 2019 and 2020.

Another very common sign of climate change is sea level rise. Since the City of Mumbai has been built below the high tide mark, the larger parts of the city are pretty much vulnerable to coastal flooding. Hence, it can be stated that soon, the sea level rise can be an issue. The sea level rise issue can potentially lead to affecting the quality of groundwater, and drinking water and also lead to Saltwater intrusion in the coastal areas. Apart from these factors, there are other detrimental effects that sea level rise can potentially create. Contamination in the drinking water can cause diarrhea cases and also cholera outbreaks. Both Mumbai and Kolkata are densely populated cities which is the reason why these cities can greatly be affected by the sea level rise. Furthermore, significant loss in the production of rice can be a problem if the rising temperatures with lower rainfall continue. Thus, Seasonal water scarcity can occur in the future and the food security of India can be disintegrated to a great extent. Another common symptom of the weather is that Heat extremes have increased while cold extremes have decreased. South Asia is the most prone to climate change. The report published by the Overseas Development Institute (ODI) think tank has claimed that negative health outcomes are projected to cost India about 3% of its GDP.

Furthermore, the Intergovernmental Panel on Climate Change (IPCC) has warned that if new trends of technology concerning global warming are not integrated, India would be in great trouble. Soon, deadly heat waves can pose a greater threat to people living in Kolkata as a result of less technological integration. Although, the Disaster management systems are integrated in India but it needs more resources to develop further.

Carbon emissions have increased to a massive degree due to the effects of transport vehicles and their growing demands. It has also set ambitious targets for renewable energy. One of the most effective solutions that can be presumed is related to sustainable sources of transport. But this prospect of creating a sustainable transport system is an unclear vision for India. Renewable energy sources are difficult to integrate because the price of battery storage is not yet falling.

Investments related to reducing Global warming could lead nations to invest around $ 900 billion. Nearly 655,400 deaths occur due to the effects of extreme cold conditions and 83,700 due to scorching heat. According to data from the European Centre for Medium-Range Weather Forecasts (ECMWF), the annual temperature of Delhi has dropped by 1.3 degrees Celsius (°C) in the last five years (2016–2020). During this period, average temperature of Mumbai rose by 0.4 °C. At the same time, while Delhi has been getting colder, Mumbai is witnessing an unusual temperature rise. On the other hand, the national capital Delhi witnessed a drop (-0.1°C) in 2019 and 2020(-0.7°C).
