AGW climate scientists seem to ignore that while the earth's surface may be warming, our atmosphere above 10,000 ft. above MSL is a refrigerator that can take water vapor scavenged from the vast oceans on earth (which are also a formidable heat sink), lift it to cold zones in the atmosphere by convective physical processes, chill it (removing vast amounts
of heat from the atmosphere) or freeze it, (removing even more vast amounts
of heat from the atmosphere) drop it on land and oceans as rain, sleet or
snow, moisturizing and cooling the soil, cooling the oceans and building polar ice caps and even more importantly, increasing the albedo
of the earth, with a critical negative feedback determining how much
of the sun's energy is reflected back into space, changing the moment
of inertia
of the earth by removing water
mass from equatorial latitudes and transporting this water vapor
mass to the poles, reducing the earth's spin axis moment
of inertia and speeding up its spin rate, etc..
