Why is India so hot and polluted to live ?

Don't get me wrong whole India is hot, but right now I am specifically talking about North India. It is still early February and temperature in Varanasi is reaching 28 C already, in lucknow it is going to cross 31 C, I am having panic attacks thinking what will happen in March, April, May and June. In summer temperature constantly hovers around 47° -48° C in North India, no one is talking about climate change in India, same is the case with air pollution in India, no one talks about it, it is like the problem doesn't exists for Indians, why can't Indians think for society for once instead of being too self centred. Winter duration has reduced to 1 month in North India while summer session duration has increased, afternoon feels hot even during winter months. Cities located in same latitude in Afghanistan, Iran and Pakistan are significantly colder. Why no one is discussing about all this? I have solution, it will sound crazy but it is our last hope. We can blow up parts of Himalayas in Nepal and Uttrakhand by Fusion bombs, I know it sounds crazy but it is our last hope to save ourselves. We can shift people from Nepal and Uttrakhand to safer places before conducting this mission. We can employ AI, machine learning to understand how to do this activity properly without impacting monsoon , natural resources and people too significantly. This will help China also, they will get trade route to India and Nepal, also dry Tibbet region might get some rainfall too. It is win-win situation for everyone. I don't have any other suggestion apart from planting more trees , reducing CO2 emissions. Do you guys have some other suggestions?
