Global warming is being caused by higher concentrations of carbon dioxide and other greenhouse gases trapping more heat in the atmosphere than normal. Humans are releasing carbon dioxide into the air faster than plants and oceans can absorb it. This extra warming will lead to problems like food and water shortages, health issues, rising sea levels, and more frequent extreme weather events. Various actions are recommended to help reduce greenhouse gas emissions, like using energy more efficiently, switching to renewable energy, and reducing waste. The evidence is clear that the average temperature has risen significantly in recent decades due to human activity.
