Global warming refers to the increase in the Earth's average temperature due to human activities like burning fossil fuels and deforestation. This causes greenhouse gases like carbon dioxide to build up in the atmosphere and trap heat. The results of global warming include rising sea levels, more extreme weather, and habitat destruction that could cause 10% of species to be lost by 2050 if current trends continue. Some ways to control global warming are to reduce fossil fuel usage, plant trees, use renewable energy, and decrease overall energy consumption through individual lifestyle changes.
