The document defines climatic change as a change in the composition of the global atmosphere due to human activity that alters natural climate variability. It lists human causes such as greenhouse gases, deforestation, fossil fuel use, and industrial processes, and natural causes like volcanic eruptions and ocean currents. The effects of climate change include rising temperatures, sea levels, and extreme weather events like droughts and heavy rainfall, which impact ecosystems and decline in crop productivity. Suggested solutions include improving energy efficiency, reducing emissions, and increasing renewable energy and carbon storage.
