Climate change refers to long-term shifts in temperatures and weather patterns. Human activities have been the main driver of climate change, primarily due to the burning of fossil fuels like coal, oil and gas.
The research activities of the Center have been oriented towards achieving fundamental understanding of the various atmospheric and climatic processes which have immense relevance to society.
