Although is still possible for a credible scientist to deny the cause and effect relationship between increased greenhouse gases and global warming, doubters are fast disappearing, White said. We re in that fuzzy period right now. Politicians can still find someone to say what they want from a credible university, White said. But, it s such a simple connection it s hard to get around, he said. Greenhouse gases, including CO2, moderate earth s temperature in a process called the Greenhouse Effect.
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. Without the greenhouse effect, earth s temperature would remain well below freezing, White said. Many people miss that basic fact. Of course it s real. We would not have a habitable planet without it, White said.
