Earth’s atmosphere contains greenhouse gases such as carbon dioxide and methane. They absorb and re-emit outgoing heat, slowing its escape to space. This natural effect keeps Earth warm enough for life.
Human activities, especially burning coal, oil and gas, add greenhouse gases. This strengthens the greenhouse effect. The planet has changed before, but the speed of recent warming makes it harder for many species to adapt or move.
Solutions include reducing fossil-fuel use, using energy more efficiently, and improving energy and transport systems. Individual habits and collective decisions both matter.
