Climate change refers to significant, long-term changes in global or regional climate patterns, primarily driven by human activities like fossil fuel burning and deforestation, leading to increased levels of greenhouse gases in the atmosphere.
This phenomenon is characterized by rising global temperatures, melting polar ice, sea level rise, and more frequent extreme weather events such as heatwaves, droughts, heavy rainfall, and intense storms. Climate change poses serious risks to natural ecosystems, agriculture, water supplies, and human health. Its impacts are global in scale and disproportionately affect vulnerable communities. Addressing climate change requires international cooperation, transitioning to renewable energy sources, sustainable practices, and adaptation strategies to mitigate its effects on the environment and society.
