The primary cause of global warming is the increase of greenhouse gases in the Earth's atmosphere, primarily carbon dioxide (CO2) and methane (CH4), due to human activities. These gases are released through burning fossil fuels, deforestation, and industrial processes. They trap heat from the sun, leading to a gradual rise in global temperatures. The consequences of global warming include climate change, extreme weather events, rising sea levels, and changes in ecosystems, impacting biodiversity and human societies. Efforts to mitigate global warming focus on reducing emissions, enhancing energy efficiency, and transitioning to renewable energy sources.
