"Does the greenhouse effect work primarily as a cooling mechanism, or a warming mechanism? Without greenhouse gases would the planet be boiling hot or bitterly cold? I believe the answer is the latter."

Why even ask the question? The earth would be a bitterly cold, lifeless shell without the greenhouse effect. What is your point?

"When I started comparing graphs of average highest temperatures, and average lowest temperatures, the difference in trends were obvious."

Well, what was your discovery? Logic says that the trend will be the same or very similar for both does it not? Are you suggesting higher highs plus lower lows or something like that? This seems to fly in the face of common sense if that is what you are suggesting. Can you please just spit it out? Thanks in adavance.
