Global climate change refers to the long-term alteration of temperature and typical weather patterns on Earth, primarily driven by human activities such as the burning of fossil fuels and deforestation. This results in the accumulation of greenhouse gases in the atmosphere, leading to a warming of the planet and disruptions to various ecosystems. Climate change impacts include rising sea levels, extreme weather events, loss of biodiversity, and threats to food security and human health. Addressing global climate change requires international cooperation and efforts to reduce greenhouse gas emissions, transition to renewable energy sources, and adapt to the changing climate.
