    Sea levels are now rising once again with the latest data point above the "means" finally. So it was only a short term down turn! Lets see if we see a period of faster sea level rises now.:badgrin:

    CU Sea Level Research Group | University of Colorado

    It appears that we're now at the second or third highest data point on the jason 1 or 2 graph!

    You have zero understanding of physics.
    Grab a glass and fill it to the brim. Put it in the freezer. It will rise out of the glass like an iceberg (or explode a bottle).Once the ice melts(it might) the sea levels will retreat.
    Here's a confused murkin bleating on the subject. murkins voted for "it".
    This B duh bess you B habbin.

    We continuously hear/read about the disastrous rise of ocean levels. Finding real world evidence of the rise is a difficult matter. Below are links to three representations of Coney island in New York.

    Pre 1900, it was an island. Now it's a peninsula and the map from 1890 compared to the areial photo from before 1990 to the "from space" photo seem to show an expanding beach and ever larger land mass exposed above water.

    Similar examples from around the world exist. Witness Venice, Spanish coastal defenses in Florida from pre 1700 and so on. If the oceans are rising, why are the shores staying where they were?

    Douger, I didn't think you were that ignorant. It is the ice on land that creates the sea level rise. And it is rising. South America has had particularly disturbing losses in their glaciers. And both Greenland and Antarctica are losing ice by the giga-tons per year.

    LOL!!! You cite all those Coney island wiki pages, but forgot the main page, which plainly says the reason it's now a peninsula is because of landfill! FAIL!

    You need to start a cherry farm.

    The reason that it's not an island is that the creek had stopped being dredged and it filled in the area between the island and the mainland. The Beach, though, was not affected by the creek, any landfill efforts or by rising sea levels.

    It is YOU who needs to show the devastating effects of the rising oceans. I don't see it and can produce examples in which the shoreline is stable for millennia or actually receding as it has near Heculaneum in Italy.

    Don't bother with the Pacific Islands that are sinking because they are sinking, not being engulfed by rising waters. Show me where there are coastal cities or beaches somewhere in the world that are being overrun by rising ocean levels. There are plenty to choose from. There have been ports in use worldwide for centuries that are still in use. Beaches that have been documented all over the world that are still in use and still, well, there.

    If there is a crisis, there should be some evidenced of it somewhere. Produce it.

    I have been going to Cocoa Beach to surf since 1971. the water is at the exact same levels today that it was when I first went there.

    Well, if anecdotes are evidence now, I've been playing golf for almost 50 years now and I've played more Jan. rounds in the last 20 than in the previous..., wait, I NEVER played golf in Jan. before that!!!

    tide gauges put the rise at ~2mm/yr since coming out of the LIA. satellite gravity measurements put the rise at ~3mm/yr since they came on line in the 90's. a lot of the satellite increase is in the parts of the world where there is a lot of seismic activity. is the extra 1mm/yr real or an artifact of the massive calculations done to produce a number out of readings that have error ranges in centimetres rather than millimetres? it is rather telling that the slow down of ocean rise in the last decade has been met with larger and larger adjustments, including the nonsensical rebound adjustment that adds 0.3mm/yr now but ignores the ridiculous results that would be present if you carried it back in time.
