The document discusses global warming, its causes, and its potential effects. It explains that global warming is caused by increased greenhouse gases like carbon dioxide and methane trapping heat in the atmosphere. These gases have increased due to activities like burning fossil fuels and deforestation. If warming continues unabated, the temperature could rise 3.5°C by 2100, with consequences like sea level rise flooding the Nile Delta in Egypt and increased drought and diseases. Individual actions like using less energy and recycling can help reduce greenhouse gas emissions and mitigate global warming.
