Does this guy Maxx really not know that the ocean is deep?
He looks at the ocean surface and asks about temperature. Everyone with half a brain understands that ocean current patterns fluctuate change the surface. The prominence of the La Nina pattern in the Pacific in recent decades by definition brings icy cold water from the depths to the surface. That has slowed warming of the atmosphere and accelerated the warming of the ocean. A third grader understands that heat moves more quickly to a colder surface. Perhaps Maxx has never picked up and ice cube. The best way to see ocean warming is to look at sea level which is rising because the oceans are warming and expanding. Every sixth grader knows that water expands as is warms. Sea level is now constantly measured by satellite.

Maxx is a guy who blocks educated people, then posts highly uneducated items. Readers can judge the basic intellect and education of climate change deniers by reading his posts. If you don't believe water expands when it warms, you might be a denier.
JimZ, you are further proving that every denier lacks basic scientific understanding. The rise of MLS is proof of warming oceans. It is called thermal expansion. I believe you will cover that when you get to 6th or 7th grade science.
It is not possible to directly measure and track water temperatures in the deepest parts of the ocean, but by measuring sea level we can see the effect of heat going into the ocean. 90% of global warming happens in the ocean. Sea level rise shows what dunces some people are when they claim global warming has paused. These people believe sea level is rising by magic.
Revisiting the Earth's sea-level and energy budgets from 1961 to 2008, Church et al, GRL. addresses many of the questions here. Sea Level is very difficult to measure with tital gauges, by most studies that attempt to do so find accelerated sea level rise comparable to the satellite measurements.
