Having a little trouble tying this together.
that's OK, so is everyone else and so am I.... but here is a crude... maybe disjointed synthesis. The devil is in the details... but this may give you some idea.
To accurately predict the future... or even claim to, is dubious.
Remember the Global Climate Change is caused by petroleum oil.... identified and detailed from every corner of the oceans... a membrane on the surface that inhibits water evaporation, turning the global hydrological cycle on its head.
"Green House" gases were saving us from the full effects for some time now.... however the equilibrium had to change... GH gases are not a problem... not even a slight problem.... if it rains often !!!!!!!!!!!!
The death of clouds, is what will happen once an area dries out... such as the Southern hemisphere already has... unlimited clear sky days....
The NH has a lot of fresh water ice melt happening... so the evaporation rate is slightly higher at the moment... not so in the south
however there is a loss of "condensation clouds" as the world's landmasses dry out... this lets through more direct sunshine.... warming, melting and precipitating various extreme weather events
BUT once the air does not have the flow through of water (liquid ->cloud -> rain somewhere...ultimately to poles ) once this stops... then Ice Clouds form
Even though there is about the same amount of water vapour pressure, the loss of condensation clouds causes that water vapour that is in the atmosphere to rise... to higher altitudes than "normal" (at normal cloud altitude the air is usually washed clean)
and the ice clouds are formed... these indicate a very dry atmosphere.
Once the ice clouds are stabilised they (continue to be sublimed by the daily sun cycle and rise again.... solidifying as ice crystals) repeat^n ..they just get higher, more stable, more dense and cover a wider area.
The effects of Ice Clouds at ground level are varied... depending on thickness.
They will form an ocean above our heads.. an ocean of ice, reflecting sunshine, trapping IR.... and many other negative effects.
Meanwhile the seas will continue to heat above natural limitations.
Natural limitations are evaporation linked, (like a thermostat) ... which loses the incoming heat..
The ubiquitous petroleum oil membrane in the marine micro-layer inhibits evaporation... therefore seas heat... a huge amount of trapped excess heat becomes a time bomb.. ----> ice age.
This is the worry.... and the Ice Clouds are a sign.... and what will happen is still highly questionable
but there can be no good come from any of this.
Most if not all the research and observations have been NH oriented... now the seas are becoming the focus...and about time... however the establishment is still in denial
Sorry, this subject is so intertwined that to elucidate all aspects in a few hundred words is impossible... but from little things big things grow, so I will try to flesh it out via answering questions.
