Asunto: Re: The reason we don't need to worry about dramatically overflooded coastlines is because H2O contracts (instead of expanding) when going from solid to liquid.

Iamon lyme: Yes.. but ice that is locked in glaciers and the like is land based and not in the sea.. unless it breaks off or melts and then adds to the sea. Certain low island already are disappearing.

"More rays are deflected with a heavier veil, therefore over time less and less heat is produced."

Interesting, but I thought that our atmosphere extended way beyond the usual water vapour range. Or it maybe I'm just remembering the problem we had with CFC's and ozone... I thought water vapour is usually invisible.. it's in the air we breath yet we do not 'see' it. If it was sulphur.. different matter, that reflects.

"but that the extremes really aren't so extreme"... it's the % of more extreme weather that is the problem. eg our UK crops are having problems due to an extremely rare dry and hot April. Food production from this season (wheat and other cereals) will be lower.
