But, it s such a simple connection it s hard to get around, he said. It's okay in this case. You're not changing the sense of what he said, and it's a really minor change. Greenhouse gases, including CO2, moderate earth s temperature in a process called the Greenhouse Effect. No upper case here.
Sunlight passes through atmospheric greenhouse gases and is reflected off the surface of the earth.
Some of this light energy is trapped by the blanket of protective gases and radiated back towards earth, warming the atmosphere. According to White, Without the greenhouse effect, earth s temperature would remain well below freezing, White said.
