Between 1979 and 2001, atmospheric temperatures above the oceans, as measured by UAH, rose slightly faster then sea surface temperatures as measured by NOAA’s ERSST series, the one now used in their global temperature datasets.
This is exactly what would be expected. As NASA explain:
Sea surface temperatures have a large influence on climate and weather. Even changes of just a few degrees Celsius can influence large-scale weather phenomena, such as El Niño or tropical cyclones. One reason for this big influence is that evaporation from the oceans is the primary source of water vapor in the atmosphere. The warmer the water, the greater the evaporation.
It is this process of evaporation which cools the oceans, and subsequently warms the atmosphere via condensation.
Moreover, temperature changes in the atmosphere tend to be greater than on the sea surface because of the much larger heat content of the…
