due to co2 we are already living in a greenhouse.Whatever one does in that greenhouse will remain in the greenhouse.INDUSTRIOUS HEAT will remain in the greenhouse instead of escaping into outer space; this is a far greater contributor to global warming than other factors and far more difficult to reduce without reducing economic activity.Like warm moist air from your mouth on cold mornings so melting antarctic ice will turn into cloud as it meets warm moist air from tropics the seas will not rise as antarctica is a huge cloud generator.A thick band of cloud around the earth will produce even temps accross the whole earth causing the wind to moderate even stop.WE should be preparing for this possible scenario»

Indeed, there is a clear physical reason why this is the case — the increase in water vapour as surface air temperature rises causes a change in the moist - adiabatic lapse rate (the decrease of temperature with height) such that the surface to mid-tropospheric gradient decreases with increasing temperature (i.e. it warms faster aloft).

Because contraction of the vortex tends to require faster rotation (conservation of angular momentum), which increases centrifugal acceleration, which opposes contraction, it becomes hard for air to flow in sideways to take the space of warmer air that is rising when the air is spinning; thus, a rising column of air can pull up on air from below.

If in exceeds out and the diffential MUST exist from top to bottom of the atmosphere, then before the hotter air can migrate to the deep ocean, the daily temerature cycling will force the hotter air at the bottom into an overall equlibrium ie hotter air will rise — or more correctly since GHGs have heated the air up more at the bottom, then the sun induced daily warming will add more heat to the top, & less at the bottom to force the equilibrium — ie effectively hot air rising even if not in actuality.

Seems to me the debate about AGHG global warming and increasing TC frequency / intensity / duration boils down to the fact that as sea surface temperatures, as well as deeper water temperatures rise, the wallop of any TC over warmer seas without mitigating circumstances like wind sheer and dry air off land masses entrained in the cyclone will likely be much more devastating.
