Nothing is powered by gravity. Every joule of potential energy stored in the half of the atmosphere being lifted against gravity is converted back to kinetic energy by the other half falling. Net zero. Where'd you learn your basic physics?
The point you were attempting to defend and that it appears you'd like me to forget was your claim that thermal energy was a "tertiary or quaternary factor" in climate. The Earth's climate is driven solely by solar energy heating air, water and earth. It is temperature differences via the Coriolis force that drive the Earth's large scale circulation. The 1C increase in temperature has created dramatic and incontrevertible changes in the Earth's climate. As temperature continues to rise, such changes will accelerate. Sea level rise, increased seasonal temperature maximums, regional droughts and regional flooding, increased hurricane and cyclone intensity, loss of ice in the Arctic, the Antarctic sheet and shelf, Greenland's sheet and shelf, glaciers and snowpack worldwide... I suspect you know the list.
