Instead, they discuss new ways of playing around with the aerosol judge factor needed to explain why 20th - century warming is about half of the warming expected for increased in GHGs; and then expand their list of fudge factors to include smaller volcanos, stratospheric water vapor (published with no estimate of uncertainty for the predicted change in Ts), transfer of heat to the deeper ocean (where changes in heat content are hard to accurately measure), etc..

Averaging about twelve feet long, they inhabit warm temperate and tropical ocean waters around the globe.

At its southeast edge, the circulation around the feature forces a salinity gradient in the ocean, with fresher and warmer waters of the western Pacific lying to its west.

A2) The Sun is the source of all this energy as it is the hottest thing around, and by the greenhouse explanation above the GHGs redistribute insolation into the ocean until their heating from above and the tendency for warm water to rise once again cancel each other out and the new stable (w.r.t. averaging over 24h) vertical gradient is attained.

Many factors — like the thermohaline circulation, which reverses direction at the poles as warm salty water releases heat into the air and sinks down to the bottom — are heavily influenced by the ocean's salinity, and thus, the movement of freshwater into and around the Arctic plays an important role in shaping both regional and global climate.

Because only very cold surface water is able to sink, it is simple to understand that the deep ocean can never warm up, regardless of how warm the surface ocean around the world may become.
