Unprecedented and Worrying Rise in Sea Levels Poses Serious Threat to Coastal Cities

Big Waves Crash Coast

A new study led by Simon Fraser University’s Dean of Science, Prof. Paul Kench, has discovered new evidence of sea-level variability in the central Indian Ocean.

The study, which provides new details about sea levels in the past, concludes that sea levels in the central Indian Ocean have risen by close to a meter in the last two centuries.

Prof. Kench says, “We know that certain types of fossil corals act as important recorders of past sea levels. By measuring the ages and the depths of these fossil corals, we are identifying that there have been periods several hundred years ago that the sea level has been much lower than we thought in parts of the Indian Ocean.”

He says understanding where sea levels have been historically, and what happens as they rise, will provide greater insights into how coral reefs systems and islands may be able to respond to the changes in sea levels in the future.

Underscoring the serious threat posed to coastal cities and communities in the region, the ongoing study, which began in 2017, further suggests that if such acceleration continues over the next century, sea levels in the Indian Ocean will have risen to their highest level ever in recorded history.

The research paper authored by Kench and others, and entitled, “Climate-forced sea-level lowstands in the Indian Ocean during the last two millennia” was published December 16, 2019, in the scientific journal Nature Geoscience.

    In Florida, where the coast is all sand, one inch of sea level rise results in 100 feet of beach erosion. A very large percentage of the population lives on the coast. The question is when will we be denied homeowners insurance? No insurance = no mortgage.

  2. One has to note that all the hyperbole regarding sea level rise ha not deterred people like former president Obama from purchasing beach front property. Apparently so long as we the little folks are sufficiently frighted by climate change those who foster the fear are fine with investing in the opposite possibillity.

  3. Watch the glaciers

    In Florida beach restoration projects can significantly increase the size of the beach by pumping beach sand back on the shore that has been washed out. Maybe a good business to start.

  5. Well, you’re in the know sailor, so you should start snapping up coastal property and then when everyone realizes it’s a big hoax you can cash in.

    NASA claims 3mm per year sea rise or about 12 inches per 96 years….so quit scare monging

  7. The ocean has been rising about 15 cm per century for the past 7000 years and it will continue to do so.

  8. I am curious. What are the level of rise around Diego Garcia BIOT?
    The US spent a lot of money there.

    The meme that President Obama bought a beach front home is a vicious LIE.
    A significant root cause of America’s quick descent into hopelessness and.inevitable apocalypse in the age of Trump is the fact that 40% of the population are unhinged from truth and reality.These people lack intelligence,discernment,and a basic sense of decency and are easy prey for manipulation via falsehoods and propaganda. Many of these evil, deranged people continue to deny climate change because they read Fox News and Russia Today etc.

    • Just google it.

    • Switch your attention to Al Gore – that great hypocrite who was awarded the Noble Prize. “In a move that critics may cite as his own inconvenient truth, former Vice President Al Gore and his wife, Tipper, have added a house in secluded Montecito, Calif., to their real estate holdings. The couple spent $8,875,000 on a gated ocean-view villa on 1 1/2 acres with a swimming pool, spa and fountains, according to real estate sources familiar with the deal. The Italian-style house has high ceilings with beams in the public rooms, a family room, a wine cellar, terraces, six fireplaces, five bedrooms and nine bathrooms in more than 6,500 square feet of living space.” You can’t get out of this one, eh?

    • I’ve always said that a liberals accusations are always a reflection or a confession. RR your post amply proves this out.

  10. NOAA released a report saying that the worst case scenarios from earlier IPCC reports are being exceeded.
    Ice melt in Antarctica and Greenland is occurring at 5 to 7 times faster than 20 years ago. This indicates the rate of acceleration of land ice melt. So a 3mm per year rise in sea level could become 20mm per year in 20 years time, 140mm per year 20 years after that, and so on. It is hard to imagine 1m of sea level rise per year but peaks of 5m per decade or even per century are not out of the question.
    People still buy low lying coastal properties but they are mainly retirees with only a few years left to go that don’t mind blowing the children’s inheritance.

    How can you write ‘unprecedented’ when the abstract says the opposite?

    “Our data also confirm the acceleration of relative sea-level rise over the past two centuries and suggest that the current magnitude and rate of sea-level rise is not unprecedented.”

  12. Left out of the above article is information from within the study itself. Note that the abstract states: “…the current magnitude and rate of sea-level rise is not unprecedented.”
    The last sentence of the paper states: “Collectively, our coral evidence suggests that rates of recent sea-level change are not unprecedented over the past two millennia.”
    Bottom line is that the article is claiming that Indo-Pacific sea levels will rise a little over 20 inches in the next 200 years.
    Time for a little truth, isn’t it?

  13. All governments have now developed secret “retreat” plans based on NOAA data. Property will be lost and no compensation offered. The reality is the oceans are warming up, therefore more volume, less ice to reflect sunlight. 1.5m rise in 10 years.

  14. Photographs of Fort Dennison & Balmoral Beach from 1902 in Sydney Harbour reveal no difference in sea level in over 100 years. At low tide those same little rocks stick just above the water line by the same amount. Just cut the BS.

  15. Really, read the paper.
    Beware this is a scammer site putting fear for a story.
    The original research document say the opposite.
    Quote:
    Our data also confirm the acceleration of relative sea-level rise over the past two centuries and suggest that the current magnitude and rate of sea-level rise is not unprecedented.

  16. Clearly whoever wrote this article either has an agenda or an inability to understand the written word.

    From the paper:
    “Our data also confirm the acceleration of relative sea-level rise over the past two centuries and suggest that the current magnitude and rate of sea-level rise is not unprecedented.

    Furthermore, the paper tells us the rate of sea-level rise was higher than now:

    “Our results provide high-fidelity observations of lower sea levels during these cool periods and show rates of change of up to 4.24 mm yr−1.”

    So is the article a lie or just incompetence?

    Either way, this website is not to be trusted.

    • Well said. The number of “not to be trusted sites” exceeds the number of sites that can be trusted. That’s how the NWO works – pummel the ignorant with false information. They lap it up.

    If you read the actual study it says “the current magnitude and rate of sea-level rise is not unprecedented” But why let the facts get in the way of a good headline!

    The mantra of the new left: “There is no need to be factually correct when you are morally right”

  18. Sea level rise can be slowed. or stoped or reverced by taking minerals out of the water by a process called mineral accretion these minerals can be used for a number of applications
