Global warming is caused by greenhouse gases like carbon dioxide and methane trapping heat in the atmosphere, raising Earth's temperatures. This causes sea levels to rise, threatening coastal areas and islands. Major contributors to global warming are fossil fuels like oil and coal, which release greenhouse gases when burned. Some ways to help address global warming include conserving energy at home, using more efficient appliances, driving less, and planting trees to absorb carbon dioxide. Whether the planet betrayed humanity or vice versa is open to debate.
