"geoscientist Jeff Severinghaus"
I worked for his father John one summer during grad school. He invented the electrode we use to measure CO2 in the blood.

"Using a new method of measuring krypton and xenon ratios in Antarctic ice core, an estimated temperature rise of just 0.1°C over the last 50 years was determined"

Sea Temperature Rise - National Geographic

Apr 27, 2010 - Global warming caused by human activities that emit heat-trapping carbon dioxide has raised the average global temperature by about 1°F (0.6°C) over the past century. In the oceans, this change has only been about 0.18°F (0.1°C).

You and Watts are comparing apples and turnips. Severinghaus' result is for "all the water in the world", including the bottom of the Marianas Deep.You are confusing that with SST, sea surface temperature.







This graph shows how the average surface temperature of the world’s oceans has changed since 1880. This graph uses the 1971 to 2000 average as a baseline for depicting change. Choosing a different baseline period would not change the shape of the data over time. The shaded band shows the range of uncertainty in the data, based on the number of measurements collected and the precision of the methods used.

Sea surface temperature increased during the 20th century and continues to rise. From 1901 through 2015, temperature rose at an average rate of 0.13°F per decade (see Figure 1).
