This visually rich poster explains Earth's climate balance step by step: sunlight enters, Earth re-radiates as infrared, greenhouse gases trap heat, and some escapes. It contrasts the natural vs. enhanced (human-caused) greenhouse effect, identifies key greenhouse gases (CO₂, CH₄, N₂O, H₂O vapor), and includes the Keeling Curve showing CO₂ rising from ~280 to 420+ ppm since 1800. Four impacts of global warming are illustrated: temperature rise, ice melt, sea level rise, and extreme weather. Pe
