I&#x27;m replying in the only place the reply button shows up in the legacy browser where I am. You finally tried to make a point with hardly any &quot;look up X, Y or Z that I know cuz I&#x27;m so smart&quot; stuff, so I&#x27;ll quote it here:<p>&quot;Remove N2 without replacing it with something else and the earth would have a much lower average temperature.&quot;<p>That&#x27;s why N2 is not considered a greenhouse gas, because anything else replacing it would do as well or better (from the greenhouse gas POV).<p>Now, instead of making stupid comments like: &quot;you are clueless about this and other topics. I would suggest a lot more research using textbooks to get a basic understanding going of chemistry, english, physics, and geology&quot;, you should try reading a commenst and replying directly to the point at hand. After a while, you might learn something.
