In addition Arhennius predicted that the night would warm faster than the day (not predicted or explained by DS), the winter faster than summer (the opposite is wrongly predicted by DS) and the land would warm
faster than over the ocean (not predicted by DS).
Air temperature over land is increasing
faster than over the oceans.

Over the past ten years, the Gulf of Maine has warmed
faster than 99 % of the global
ocean.
MHW intensity between 1982 — 1998 and 2000 — 2016 increased in
over 65 % of the global
ocean, most notably in all five western boundary current regions, where the mean warming has been considerably
faster than the global average39, and most mid-latitude
ocean basins (Fig. 1e).
The former is likely to overestimate the true global SAT trend (since the
oceans do not warm as
fast as the land), while the latter may underestimate the true trend, since the SAT
over the
ocean is predicted to rise at a slightly higher rate
than the SST.
The former is likely to overestimate the true global surface air temperature trend (since the
oceans do not warm as
fast as the land), while the latter may underestimate the true trend, since the air temperature
over the
ocean is predicted to rise at a slightly higher rate
than the
ocean temperature.

Over very long time periods such that the carbon cycle is in equilibrium with the climate, one gets a sensitivity to global temperature of about 20 ppm CO2 / deg C, or 75 ppb CH4 / deg C. On shorter timescales, the sensitivity for CO2 must be less (since there is no time for the deep ocean to come into balance), and variations over the last 1000 years or so (which are less than 10 ppm), indicate that even if Moberg is correct, the maximum sensitivity is around 15 ppm CO2 / deg C. CH4 reacts faster, but even for short term excursions (such as the 8.2 kyr event) has a similar sensitiv

Given that the most of the melting that goes on is from the underneath (i.e. under the water) and
ocean heat content is at modern highs, and the
oceans have even released a bit less energy
than average
over the past 15 years, it is not a coincidence that ice would de line even
faster during this period.
Since the source of anthropogenic global warming is ostensibly increasing concentration of CO2 in the atmosphere, it makes no sense to posit that
over time the
oceans will warm at a
faster rate
than the atmosphere above them.
Longer records now available show significantly
faster rates of warming
over land
than ocean in the past two decades (about 0.27 °C vs. 0.13 °C per decade).
Verify using data collected only
over the 1/3 of the planet that is covered with land strikes me as odd, particularly because we expect the land temperatures to rise
faster than ocean temperatures.
Surface temperatures
over land regions have warmed at a
faster rate
than over the
oceans in both hemispheres.
Qin Dahe, also co-chair of the working group, said: «As the
ocean warm, and glaciers and ice sheets reduce, global mean sea level will continue to rise, but at a
faster rate
than we have experienced
over the past 40 years.»

The extra heat in the
ocean has caused the sea level to rise 15 mm since November 2014, much
faster than the rate of 3 - 3.5 mm per year

I can only imagine it is an effect of drying
over land areas, which is expected if land warms
faster than the
ocean.
The CO2 doubling response from CM2.6,
over 70 - 80 years, shows that upper -
ocean (0 - 300 m) temperature in the Northwest Atlantic Shelf warms at a rate nearly twice as
fast as the coarser models and nearly three times
faster than the global average.
Nor is there good observational evidence that air
over the open
ocean warms
faster than SST.
The paper REA16 primarily cite to support
faster warming of tas

ocean causing a lag in
ocean warming.
