    Don't we have a way to measure this accurately once and for all?

    We know many cities are having problems with flooding now. Either the ocean is rising or land is settling down.

    There must be a way to accurately measure this and put an end to the speculation, isn't there? Are we only able to measure accurate elevation in relation to something nearby?

    It is possible to measure it. For example, the West Coast is rising (thus the Rocky mountains) and the East Coast is subsiding. Measurements at the beach are not an indication of rising ocean levels. One of the pseudo-science fallacies is that melting Arctic ice will rise ocean levels. It will contract as it melts and the ocean level won't change.

    I believe Hoyt posted awhile back on this topic that Florida was sinking and the
    Data was from CLEAN sources.

    Is there a specialized altimeter that would give an elevation accurate to the foot or fraction of a foot?
    How accurate is GPS now for elevation?

    We live in a dynamic universe and on a dynamic planet where everything is changing and some people call that "time" but it is realy just change. Everything changes and Human activity must have some effects because we are here.
    If we do not adapt we do not survive.If we keep on over populating the earth Nature will do it for us in the form of world wide disease and famine. I just can not get my spell check to work.

    Altimeters traditionally measure from sea level. We should measure from the center of the Earth for the term "rising" to make sense worldwide. Most claims are set to support the claims being made and don't give what the datum is.

    Humans are 70% water. If you get rid of the humans there will definitely be an increase in water level. Average weight of human is between 45-50kg(containing between 32-35 litres of water) so multiply that by number of humans and that would add a lot of water to the water cycle.

    Could you correct the spelling in the thread title?

    It's not that bad. Over at another forum I go to someone recently discussed some guys being charged with "conspiracy to distribute judges", not "drugs" as he'd intended, though an all time classic from there would be that "the price of gay" (gas) thread.

    This link gives a simplified technical description of how sea level is accurately measured.

    Measuring Sea Level

    This link has an interesting video showing some of the issues involved in figuring out exactly where sea level is.

    The Surprisingly Complex Way That Scientists Measure Sea Level

    (if the video is blocked by a black square (Firefox??), you can also see it directly on YouTube -- http://www.youtube.com/watch?v=q65O3qA0-n4)
