Claim: Seas Are Rising at Fastest Rate in Last 28 Centuries

But Miami Beach, for example, is built on a manmade island.

This non-scientific study is full of bogus precision:

How can they know the ocean surface dropped by 3 inches during the Middle Ages? Satellite data — which only started in 1993 (TOPEX)?

  1. Here’s the abstract:

    We present the first, to our knowledge, estimate of global sea-level (GSL) change over the last ∼3,000 years that is based upon statistical synthesis of a global database of regional sea-level reconstructions. GSL varied by ∼±8 cm over the pre-Industrial Common Era, with a notable decline over 1000–1400 CE coinciding with ∼0.2 °C of global cooling. The 20th century rise was extremely likely faster than during any of the 27 previous centuries. Semiempirical modeling indicates that, without global warming, GSL in the 20th century very likely would have risen by between −3 cm and +7 cm, rather than the ∼14 cm observed. Semiempirical 21st century projections largely reconcile differences between Intergovernmental Panel on Climate Change projections and semiempirical models.

    Note the “reconstruction” “semi-empirical modelling” measurements of sea level to cms in the middle ages, etc. This is all about models not observations.

  2. ?No comprende’ computer simulated water — and/or computer simulated thermal energy — being added to the world’s oceans?
