No you are bringing up an irrelavent point, I could bring up venus, where a runaway greenhouse effect has taken hold due to these greenhouse gasses
BUT I DIDNT, BECAUSE LIKE MARS IT WOULD BE IRRELAVENT, AND I UNDERSTAND HOW TO MAKE A SCIENTIFIC ARGUMENT.
You apparently don't.
Mars is a planet that is alien and we have very incomplete data on it- we know virtually nothing of its climatic long term history. My argument and the facts I presented were based not on the past couple of decades of data but on centuries and millennia- I listed the facts and told you to address them... you havent, and you apparently cant.
