Global warming is happening because

Answer 1

Earth's atmosphere has a lot of carbon dioxide. When heat from the sun penetrates the atmosphere, the carbon dioxide makes it hard to return back to space. So minimal heat gets reflected. This is what you call the greenhouse effect. The heat gets trapped inside our atmosphere. This is global warming.

Answer 2

of the increase in greenhouse gases like carbon dioxide and methane in the atmosphere, which trap heat and result in the warming of the Earth's surface. This is mainly due to human activities such as burning fossil fuels, deforestation, and industrial processes that release these gases into the air at an unprecedented rate. The resulting changes in climate patterns are leading to rising temperatures, melting ice caps, and extreme weather events.
