The Impact of Human Activity on Climate Change and Global Warming

The Earth's climate has fluctuated for millions of years, but recent human activities have accelerated global warming. Since the industrial revolution, burning fossil fuels has increased greenhouse gases, intensifying the greenhouse effect. Evidence includes rising temperatures, shrinking Arctic ice, and high greenhouse gas levels. Predictions suggest further warming, with potential impacts like rising sea levels and extreme weather. Mitigation efforts focus on reducing emissions, with consumers encouraged to save energy and adopt sustainable practices.
