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»

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.

Similar negative effects occur with worsening air pollution — higher levels of ground - level ozone smog and other pollutants that increase with warmer temperatures have been directly linked with increased rates of respiratory and cardiovascular disease — food production and safety — warmer temperatures and varying rainfall patterns mess up staple crop yields and aid the migration and breeding of pests that can devastate crops — flooding — as rising sea levels make coastal areas and densely - populated river deltas more susceptible to storm surges and flooding that result from severe weather — and wildfires, which can be ancillary to increased heat waves and are also responsible for poor air quality (not to mention burning people's homes and crops).

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.

More clouds both drastically reduce energy input from the sun and simply slow release of what energy there is trapped in the lower troposphere, but the long term effect would be a fall in average temperature because of the significantly reduced input power but the atmosphere's ability to cool is aided by air current circulation whereby the warmer air rises above those low clouds and that infra - red is more easily re-emitted into space, whereby the low clouds now block that re-emission from hitting the ground again to any significant degree.

The point is that the formula for the DALR comes from the assumption that the air heats down low and rises, expanding adiabatically into the air above it (doing work against its increased pressure / density) and cooling as a consequence, a process that only «stops» when there is a uniform lapse between the warm bottom and the actively cooled top.

When the intensity of ultraviolet light from the sun increases, temperature rises in this ozone rich air and weakens the downdraft, lowers the surface pressure and with it the strength of the trade winds that blow across the ocean to the low pressure zones that form over the warm waters that accumulate in the west.

The IPCC report and its publicity statements deliberately distort the continued ocean temperature rise by conflating it with «global warming» when it is merely the transfer of air heat into the oceans from the temperature rise prior to 1998, not CO2 induced air warming since 1998.

DWR54 wrote: «Most of the heat coming off the ground (or walls, etc) is convection — or «net» transfer of heat from a warmer to a cooler medium, typically causing heat to rise from the surface into the cooler air aloft.

It is warmer than the rising air coming up from the surface below, so it effectively puts a lid on convection.

Of course, if the air were to be warmer than the ocean surface then evaporation would take the extra energy required from the air rather than the water and that 1 mm deep layer (0.3 C cooler than the ocean bulk) would rise to the surface and dissipate but that doesn't happen often or for long.

The AVE AERO mimics nature producing renewable energy cheaper than fossil fuelled plants by extracting energy from rising warm air.
