I've been hearing a lot about global warming lately. What is it and how can I help stop it?

Global warming is the long-term increase in average temperature of Earth's atmosphere, oceans, and land surface. It is caused by human activities that release greenhouse gases such as carbon dioxide into the atmosphere. These activities include burning fossil fuels for energy, deforestation, and industrial farming. The resulting increased concentrations of these gases trap heat within the atmosphere, causing temperatures to rise and leading to more extreme weather events.
