Abstract
Climate is the average weather condition of a large area over 30-35 years. At present, a major change in this climate is being noticed. There are different causes behind it. These climate change issues are very complex. Causes can be broadly divided into three categories. Namely - Astronomical observations - including solar variability, elliptical orbit changes, orbital shape changes, solar heating, changes in Earth's temperature and changes in cosmic rays. Secondly Atmospheric causes -Heat retention is caused by some atmospheric gases, such as gaseous water vapour (not droplets),carbon dioxide, methane(CH),NO and a few other miscellaneous gases. Mainly due to various human activities, anthropogenic emissions from industry, fossil and biofuel emissions, transportation and ships etc., massive temperature rise is observed. Thirdly, tectonic theory - the movement of the continents, the change in the flow of ocean currents, the temperature difference due to eruption due to plate movement is one of the theories. Which indicates climate change. In addition to the facts, the effects of climate change are discussed. Seawater inflation due to temperature variations due to the effect of various gases affects marine biodiversity, life and livelihoods of coastal communities. Snowmelt, which greatly affects the intensity of cyclones, is discussed in detail.
