The reason cold sea surface water will be further away from the satellite than warm sea surface water is because the satellites are placed a relatively fixed height. The waters levels however are not.
Explanation:
Whenever the climate heats up, sea water level rises because:
first, the sea water expands as it is heated up;
second, as the climate and the sea gets warmers, the icecaps melt. Both action give an upward spiral to the water level.
So, because the satellites are fixed but the water level is rising, the distance between the satellites and the warm sea surface water is reduced.
In contrast, as the climate gets cooler, water contracts and freezes up and cause the water level to shrink thus causing the satellite to be 'farther away' from the surface of the water.
Secretary of State John Foster Dulles defined the Middle East as "the area lying between and including Libya on the west and Pakistan on the east, Syria and Iraq on the North and the Arabian peninsula to the south, plus the Sudan and Ethiopia."
Higher temperatures may reduce the availability of drinking water by provoking the loss of mountain glaciers and mountain snowpack, and causing earlier spring snowmelts—all of which reduces the amount of available water in streams, rivers, and other bodies of water.
