Global warming is an increase in the Earth's average temperature caused by greenhouse gases trapping heat in the atmosphere. The main causes of global warming are greenhouse gases from industries and vehicles, as well as deforestation. If unchecked, global warming will lead to rising sea levels from melting ice caps and more extreme weather events like hurricanes. Most people now believe that global warming is occurring and efforts are needed to reduce greenhouse gas emissions through conservation and use of renewable energy.
