Some people will put down the disinformation spread by Anthony Watts to him being plain dumb and ignorant. Others will say that he's not really as dumb as he looks and sounds, he's just deceitful and has made a business out of conning the ignorant.
I don't know where on the idiot-liar scale Anthony Watts lies.
These past couple of days Anthony Watts has:
- Complained that responsible journalists don't go to flat earthers for science
- Failed ocean chemistry
- Failed surface temperatures 101
Now he's claiming (archived here) that John Cook at SkepticalScience.com said that Antarctic sea ice is the result of the Southern Ocean getting warmer. He even linked to the web page where John Cook gave the following reasons for the increase in Antarctic sea ice:
- the drop in ozone levels over Antarctica, resulting in stronger winds, which creates polynas, which freeze up and add to sea ice.
- a change in ocean circulation with top layer of the ocean being colder and fresher, which freezes more easily than more saline water at the same temperature. It's colder at the top because of more snow and rain as a result of warmer air temperatures.
