Abstract

Man is a passive agent for all the natural events. If man is inactive for all the natural hazards then how can he be active only for one climatic event i.e. global warming? Due to global warming temperature is increasing and the situation is deteriorating day by day. It is believed that there is increase in the percentage of carbon dioxide in the atmosphere and so the global warming is taking place. The carbon dioxide traps the long wave terrestrial radiations and increases the temperature. The increase in its percentage is due to automobile and industrialization. It means the increase in the parentage of CO₂ is anthropogenic. Gangotri glacier has attracted international attention because of its rapid rate of retreat. No doubt it is retreating but the rate of retreat is decreasing for the last few years, so it is not in accordance with global warming. If global warming is only reason for the rapid rate of retreat, then all the glaciers should retreat at the same rate, which is not the case. It means there are local reasons other than global warming which are responsible for rapid rate of the retreat. Climate change is significant and lasting changes in the statistical distribution of weather patterns over periods ranging from decades to millions of year that is change in average weather. The most probable cause of climate changes are the human activities which are burning of fossil fuels and deforestation that leads to the increase in carbon dioxide production. There is a sudden outbreak of Corona virus disease which has killed over 2,34,000 people and infected more than 33 lakhs in 212 countries of the world.
