    Sounds like there are way more factors effecting sea levels than supposed Global Warming or Climate change.....
    1. Gravity,
    2. Currents,
    3. Trade winds,
    4. Temperature differences (seasons?)
    5. Coriolis effects (Earth rotation?)
    6. Vertical land movements,
    7. Under sea land drops/fissures (not mentioned by yourself, but happen) - more likely to decrease levels? But I question that anyway - given the astronomical body of water that covers the planet.

    These factors you mention are all not really new, and a pretty significant set of influences.

    Lucky we are going flat out to restrict Carbon emissions....wouldn't want more trees to grow

    Yes, it does. The average 1kg weighs on earth is around 9.81N (weight is generally talked about in kilograms, but should actually be in Newtons as weight is a force, not a mass).

    So you've got this, you've got the Coriolis effect, you've got the impact of currents, you've got the impact of temperature (water contracts and expands with temperature changes), etc.

    All of these make a small(ish) difference, but can certainly account for a difference in sea levels.

    Well, a difference in gravity certainly wont. If a certain spot in the ocean has a tiny difference in gravity, and lets be real, it's going to be miniscule! An mgal is 0.00001 m/second squared? Compared to 9.8 m/second squared. Then this certain spot is still going to rise or fall at the same rate as somewhere else. That is my point. The difference in gravity is constant in a certain spot.

    See ya's.

    A second ago you didn't believe that the gravitational pull could change across the world and now you're lecturing us on the effects of it?

    Not at all.

    Watagos said,
    "the sea level rises by vastly different degrees as a result of different effects of gravity"

    I disputed that. And I still do. It would have no effect, as the gravity difference is constant. And it certainly is not "Vastly different". The Coriolis effect is also a constant. So how does that make the ocean level change at different rates? It's going to change at the same rate.

    I've always known that gravity has a slight difference in different spots. It is slightly different at the top of mount Everest. A kilo will weigh slightly different at the equator due to the rotation of the earth.

    See ya's.

    You guys off topic, sea level rises are supposed to be caused by climate change.

    Not natural effects of gravity etc.

    LOL, round and round we go again. Nothing changes between SS & PC.

    This is where the GW and CC crowd do themselves no favours - everything is sooo alarmist and armageddon - and we caused/are causing it, but then they turn around and blame massive Earth movements as well.

    A massive Earth movement would be; earthquake, volcano eruption, cyclone prolonged periods of drought or cold and extreme snow/rain fall/floods.

    The intensity and zealousness - it's like Christians trying to bible bash everyone.

    The measurement changes may be tiny whilst their effects are enormous. Consider, for example, a diet of 0.01% cyanide.

    "Hardly any of his diet was cyanide" and "He's dead from cyanide poisoning!" are talking about the same thing.

    No it wasnt off topic, it was part of the explanation why sea levels are rising differently in different places. Gravitational effects play a part in this, the effects are not minuscule.

    No one is blaming massive earth movements, its just a reference to a non-climate change reason why some local observations are different, gradual vertical land movements (continental plate movements, subsidence, etc.).

    Well, we are talking about ocean levels? Surely a 10 cm rise is a 10 cm rise no matter how you look at it? And oceans in theory should have been rising for 500 years since the depths of the little ice age you'd think?

    See ya's.

    Yep; heard that one too.

    More contradiction.

    Seas level rises - as far as I can gather from all this discussion - is supposedly a result of melting polar caps, which is supposedly a combo of sea and air temp rises? Isn't this due to GW?

    More scaremongering.

    Earth's climate and temp changes have never been exponential - if they were; there would be nothing alive right now.

    There is some argument that a dust cloud (from a giant meterorite or other crash on Earth) caused many years of little light, and destroyed the dinosaurs - but that is not an exponential weather change.

    Never had 6-7 billion people collectively burning fossil fuels before either.

    Where has the ocean experienced a 10cm rise?

    Um; there have been bushfires burning on Earth since God's great grandfather was a baby.

    Since you mentioned population size - time for a zero population growth program for a few centuries to decrease the risk?

    Or shall we just keep on pumping more millions of folks out every year, and hope to find a a way to curb our pollution destruction? The 2 mice in the box syndrome.

    I think we are looking at the wrong end of the CC/GW problem - if there is one.

    Um yes bushfires and volcanoes and now 6-7 billion people added to the mix as well.

    Dunno BV. I just plucked the figure out of thin air? But the oceans in theory should have been rising for 500 years as the earths temperature has risen. We know this, as we also know the ocean was tens, if not hundreds of metres lower 15 thousand years ago in the last ice age when humans walked from mainland Australia to Tasmania.

    See ya's.

    Correct. Port Philip Bay was originally a stream, and apparently filled up to it's present level around the end of the last ice-age.

    Does this mean the temps have been going up ever since???;)
