Well excuse me for being pedantic but it does say "simply because seawater would continue warming up, which makes it expand", So any of your ideas about all the rest of it are neither here nor there if we are to take this statement literally. Plus it has everything to do with water in test tubes. It's all H2O and it all expands at the same rate.

Did you know by the way that the amount of evaporation is exponentially proportional to temperature? How much effect this will have is something I have not calculated but it's worth considering. Plus of course you know it will form clouds and the clouds will block out the sunlight. So 'simply' was the wrong word to use.

You are incorrect in stating that it has everything to do with test tubes.
You must consider the time it takes for heat to spread throughout the volume of water, for one.
Also, is it all H2O in our oceans? Funny; I thought they were also comprised of a large amount of salt and other impurities, which affects density.

Also, it does not just say that which you said. It quantifies the rise as well:
Also, you are correct regarding evaporation, but then you also do not consider that as temperature increases the residence time of water in the atmosphere decreases, meaning that though there is an increase in the amount going up, there is also an increase in the amount going down.

No it does not work like that. It's a dynamic equilibrium. Look up Boltzmann distribution and that should explain. Simply the filtering is proportional quantity, as you would expect. All other effects will be second order or less and are not too important. Now you mention salt but that is going to remain fairly constant except for the small change in evaporated water. That's why you need test tubes! Stick some salt in and see what happens.

In my opinion, the worst policy is the "green tax" policy on CO2 so oft touted by the IPCC. The UK Government has (suspiciously) gone way overboard on this "requirement", so people like me would now have no energy autonomy if our parents leave home. The worst thing about "green tax" policies is the fundamental assumption that because a country is in the G8, everyone must be rich and therefore able to pay £30-£50 for every tonne of CO2 produced. I am not wealthy! I live in the Styx! There is not much hope for me! I cannot support KYOTO tax because it hurts homosexuals (who will have no future children for which to buy a climate), the elderly (who struggle with council tax, steep rises in energy bills, etc.), people who live in rural areas (who need a car to travel) and the poor (who won't be able to heat their homes in winter). Given that we are still in a hydrocarbon age and that CO2 levels are nowhere near toxic yet, the attack on CO2 seems completely out of place. There is sufficient time to develop and implement technologies to replace non-renewable hydrocarbons, at the current rate of progress. All I know is that giving Government an unprecedented windfall won't speed up technology to transition from the end of the oil age.
