Anthony Watts' blog is where science deniers congregate so they don't feel so alone in the world. Usually they are simply rejecting climate science, the greenhouse effect, rising global surface temperatures and anything else that takes their fancy that's to do with climate. They don't normally get into rejecting biology or not openly at least. They will from time to time reject chemistry, usually in relation to ocean acidification.
Today I see that a guest essayist has decided to reject gravity and probably momentum. He was writing about a paper in Science from last week, which got denier blogs all a twitter. The paper is probably raising some eyebrows among scientists too. It's an interesting take on where the heat is going.
Before I get to that, though, let me show you what David "funny sunny" Archibald wrote about thermohaline circulation (archived here). He posted this image from an article in last week's Science, which Eli Kintisch wrote about the subject:

David Archibald said it can't be so. He wrote:
The illustration shows heat plunging into the depths as far as 1,500 metres. The oceans don’t work like that. Most of the heat energy of sunlight is absorbed in the first few centimetres of the ocean’s surface. Waves mix the water near the surface layer such that the temperature may be relatively uniform in the top 100 metres. Below that there is almost no mixing and no vertical movement of water.
Some of what he wrote was okay, sort of. Some of it was very wrong. In particular, he he is rejecting thermohaline circulation, arguing there is no vertical movement of water in the ocean. He's wrong of course. Thermohaline circulation is the convection in the ocean driven by pressure gradients and gravity. Saltier water is denser than fresh water. Cold water is denser than warm water. Colder saltier water sinks in the ocean. This process doesn't stop and start, or not easily and not often. There's a lot of momentum behind the conveyor belt. There's a huge amount of water going through this cycle. Just because some of it is a bit warmer at times doesn't mean the water stops moving.
