TRCS, The Right Climate Stuff: Retired NASA Apollo Moon Program scientists, engineers and select others. Will increased levels of atmospheric carbon dioxide emitted from human activity reach a level that endangers human welfare and the health of the biosphere? The answer to this question has been the focus of The Right Climate Stuff research team. Our conclusion? Not likely. The rationale for this conclusion is the subject of this paper where we find that it is highly unlikely that added carbon dioxide and other greenhouse gases will add more than 1.8 OC of warmth by the middle of the next century. This bounding of potential warming means that we do not have a rapidly developing climate problem requiring swift corrective action and transformation of economies.
