Global warming isn't just from CO2; other factors play a role. The greenhouse effect traps heat from the Earth and infrared radiation, leading to warming. Burning fossil fuels adds extra CO2. Artificial surfaces also emit heat, further disrupting the natural greenhouse balance. Fossil fuel heat release directly warms the air, raising temperatures over time. This leads to a significant temperature increase of 12.2°C per century. Multiple factors, not just CO2, contribute to global warming, impacting our planet's climate.
