Now we get to the problem. Long wave IR doesn't heat water. Not even a tiny little bit because it is incapable of penetrating the skin of the water.
A staple part of Westwall pseudoscience is denying conservation of energy. In his strange world, energy strikes the oceans, and then simply vanishes into a magic snowflake dimension. According to the Westwall "energy can't warm something unless it penetrates deeply" theory, sunlight can't possibly heat a rock, because it only penetrates a few microns into the rock. Since sunlight clearly will heat a rock, the Westwall theory is clearly hilariously stupid.
So, how does Westwall explain why barely-penetrating EM energy can heat a rock but not the oceans? He doesn't. We're supposed to take it on faith. I've asked. He won't tell. He'll try to deflect by yelling something like "thermal ....", which also doesn't make any sense, then he'll snarl out some insults and run.
The point? All of his "science" is hilariously stupid. Most denier "science" is hilariously stupid. Unlike the real climate science, which can be disproved in many ways, denialism is impossible to disprove. I've asked deniers what evidence would disprove their beliefs, and none of them can give an answer. There's literally no data that could disprove their beliefs. That puts denialism in the realm of pseudoscience or religion.
So, that's why deniers can't be trusted. They don't do science. They just chant religious mantras.
Plus, look at this thread. All the deniers are wild-eyed fanatics, frothing out conspiracy theories about the VastSecretGlobalSocialistPlot. You can't trust conspiracy fanatics. You can trust people who calmly discuss science and calmly defend their views, like the rational people do.
