With the passage of time, the Earth's climate has undergone significant changes. Rapid climate change presents different challenges for the organisms. Evolutionary adaptation can help the species to cope with climate change, but it is not a guarantee of survival. Natural greenhouse gases and various other parameters of climate change play a vital role in regulating the earth’s temperature, wind pressure, humidity, and precipitation pattern. Due to the presence of significant carbon compounds in air the temperature of earth has increased, which in turn causes a decrease in oxygen level in aquatic habitats and on land creating a challenging environment for many organisms. There is a range of measures that can be taken to avoid and mitigate climate change and ensure a livable future for generations to come. The proposed study will be helpful to understand the basic chemistry of climate change, the mechanisms of adaptation and its significant impacts on a variety of organisms.
