Why do you keep repeating the same lies. What you keep saying what was said is not what was said at all. You keep saying the same twisted things that were not part of the argument at all.

The Wikipedia article doesn't say that the greenhouse is warmed by convection. It says it is warmed by solar radiation: A greenhouse is built of glass; it heats up primarily because the Sun warms the ground inside it, which warms the air near the ground, and this air is prevented from rising and flowing away. But it is cooled (and thus the temperature regulated) by suppressing convection: The warming inside a greenhouse thus occurs by suppressing convection and turbulent mixing. This can be demonstrated by opening a small window near the roof of a greenhouse: the temperature will drop considerably. Personally, I don't care much about the argument. I actually thought that the article agreed with you more than the other guy. But I haven't read every post, and haven't really followed it particularly closely. And I don't pretend to be a scientist--I'm just an educated lay person when it comes to science matters.
