GreenHouse Gas, Incoming Solar Radiation... are not completely unknown. But I dislike acronyms. Not every reader works in this field, not everyone is a native English speaker. The very minimum is to provide a list of acronyms with explanations, and it would be better to avoid them completely where possible. I understand their usefulness in chemical reactions, not in satellite construction. Many people use tons of them only because they saw other people do it and imagine it looks professional.
About this text: sorry, it seems to me that there is nothing to understand, hence nothing to refute. But anyway, the greenhouse effect, prior to excess CO2 injected in the atmosphere by humans since the industrial revolution, already made our Earth some 15K warmer. The mean temperature without greenhouse effect can be estimated by hand.
