Edited sentence: By 1986 the TTAPS study was comprehensively discredited, and in succeeding years, as supercomputers have allowed  more accurate atmospheric modeling, it has become the target of derision by both sides of the "nuclear winter" debate (such little debate as remains) since its conclusions are clearly unsupportable.Oceans, of course, have a gigantic capacity to release or absorb heat, and would clearly have an enormous effect on the world's climate under any circumstances, including after a nuclear war.The TTAPS study is often used as an example of "junk science," or as an example of a scientific study being made while seeking a predetermined conclusion.The model also assumed a solid, flat earth that was one barren piece of rock, with no mountains, no trees, and even went as far as discounting the effects of oceans on global climate
