Global warming is caused by greenhouse gases trapping heat in the atmosphere. The main greenhouse gases are released by human activities like burning fossil fuels and deforestation. This is accelerating the natural greenhouse effect and causing average global temperatures to rise rapidly. Effects of climate change include changes in weather patterns, melting ice caps and glaciers, and the spread of diseases. To mitigate these impacts, humans must transition away from fossil fuels to clean and renewable energy sources like solar, wind, and hydroelectric power.
