This is relevant how? Do you think warming based sea level changes will eliminate natural tidal changes? It's not one or the other. No one is saying we're going to see floods during low tide.
Justin -- there is no chance of significant warnming based sea kevel change in your lifetime
You can do the experiments at home with a meauring cup, or ideally a graduated cylinder, a thermometer and a source of heat:
1) direct effect of warming the ocean increasing its volume and hence raising sea level:
a) the sensitivity of the ocean volume to a fraction of a degree change in temperature is very small
b) ocean basins widen as you rise from the botton hence any increase in volume leads to reduced rise in sea level
2) melting ice:
a) the ice that is floating on the ocean -- most susceptible to melting -- well it is floating so when you melt it -- it actually takes up less volume -- drop an ice cube in a cup fill it to the top with room temperature water -- come back when the cube has melted - where did the water go?
b) the land-locked ice - mostly Antartica - -its actually getting colder - no melting here
No most sea level is locally determined by rising and subsiding of land as water is pumped or local geology influences things
Finally the reason for the references to the tides and winds, depressions, etc -- we have to deal with these on a day to day, month to month basis already. Some places on the immediate coast do have sea wallls that get overtopped occasionally and some basements get wet. However, the vast amount of flooding even in coastal communities comes from rain falling in-land filling and over flowing, tidal creeks, drainage ditches and sewer outfalls.
Worry about mega-solar activity and the potential damage to the electric power grid -- that is a real -- not if but when that we should be directly planning for mitigating.
