Sea level is actually very complicated to measure so rather than explain all the variables gravity, spin, light breeze, isostatic rebound can skew early measurements they did in ports of olde –actually let’s say Scotland is rising and England is sinking, thermal expansion, etc it’s a very long list I will just look at some muffin porn for a minute or two....ahhhh. Sea levels rises and its kinda one Sea (Ocean) – there is no counter argument, none at all. Why it rises is a little more complex. 1 The natural ebb and flow of mother earth a vast & truly complex system/equilibrium meandering and spanning all epochs. 2 Man – Working out precisely point 1 contribution is actually impossible, far from perfect. Therefore data will always be refined and that seems logical. 3. Saying man has no contributed is invalid. To prove that absolutely is impossible for now. But they will take their data/inferred from many sources: cores, coral, fauna, fossils, etc and say hmm there seems to be something amiss. And we attribute that to man. And so they should. Who does it matter - many a reason as I said eg London is sinking, sea level are rising, and the Thames Barrier probably had a design life off 80 years originally and I think they have to redesign it/modify it within the next 20-40 years (alas i cant remember the exact figures) and eg New York too is susceptible to high tides/storm surges... So looking at the fact most of the world population lives around about sea level, as they have since the beginning of time (hence all em underwater cities)...wait this will be too boring Actually you can look at it this way Major cities will be more susceptible to flooding/inundation. but they always have been since the beginning of time due to mother earth/LGM interglacial etc So what man contributes a centimetre a century (yes I plucked that figure out of thin air to use as an example i could have used 10cm a foot) and mother earthly currently lets call that another cm a and thermal expansion a tenth of that. Big fuking deal and it isn't except but for the kick in the teeth bite in the ass in that more energy is going into the atmosphere and this is not a good thing.. I know you two know about glaciers, LGM glacial outburst, albido etc which would cause sea level to rise suddenly very short period of time, in big steps of oh 100 metre per century; from about 21K BP....well a few occurrences in-between bit no-one ios here for a lesson in geology..but worth a mention Now Greenland is fuked. And if it all melted it would add 7 metres to current sea levels so in the next 100-300 years they have that to look forward to, plus the energy it adds to the atmosphere Antarctica is a little bit different But in the past iceball earth, or whatever they call it, happened they think on two occasions and planet earth has been ice free many a time (for a variety of reasons to many too mention) and life still goes on, has went on since the beginning of time..granted its been too the precipice on many occasions and even irradiated But you have a brain Op, I think, unless you are just reading selective material so I never really understand anyone saying sea level temperatures arnt rise in part as a result of man.
