🌡️ Earth's Thermal Blanket

Without the greenhouse effect, Earth's average temperature would be about -18°C — a frozen wasteland uninhabitable for most life. Instead, the natural greenhouse effect keeps our planet at a comfortable +15°C. The same process that makes life possible, however, is being enhanced by human activities, trapping more and more heat. Understanding the mechanism behind this effect is one of the most important topics in modern chemistry — and one of the most frequently examined.
