This presentation discusses global warming and the greenhouse effect. It explains that greenhouse gases like carbon dioxide and methane trap heat in the atmosphere, causing global temperatures to rise. The main causes of increased greenhouse gases are human activities like burning fossil fuels and deforestation. If greenhouse gas levels continue to increase it will lead to problems like rising sea levels, more extreme weather, and disrupted ecosystems. Reducing emissions from fossil fuels and increasing renewable energy and tree planting can help address the climate change issue.
