This is a new one for me.

Yesterday I heard a new excuse to support the argument that humans are in no way responsible for contributing to global warming.

Underwater volcanoes.

I guess they couldn't convince any sane person that land based volcanoes are responsible for global warming, so now deniers are looking underwater.

It's just amazing to watch the "wheels" of pseudo-science in action.
