The title of this article asks two questions. The author does not answer either of them. He explains how molecules like CO2 and H2O can (and they do) absorb and re-emit (i.e. scatter) specific wavelengths of infrared radiation (aka IR radiation). He is not wrong about that, but much of what he says is opinion or conjecture, and he leaves out a great deal of factual information that makes the anthropogenic global warming (AGW) narrative to be completely bogus. None of what he says answers these 2 questions. He just dodges them.
