A 2 m rise in sea level by 2100
is just physically impossible nonsense
Paleogeophysics & Geodynamics, Stockholm, Sweden
There are physical laws setting the frames of possible rate of sea level rise, rate of
ice melting and thermal expansion of water (Figure 1). As true scientists, we must
provide statements and estimates that respect those frames (i.e. lie within the blue
box of Figure 1). Ignoring the frames, and you are in the pink field of nonsense.
Recently (and just in time of the EU election in Europe), a paper has appeared,
which surely represents another visit to the “pink field of nonsense”. The paper is
written by a well-known group of IPCC/AGW proponents (Bamber et al., 2019).
Significantly, there is not a single reference to observational facts in nature itself,
documenting a diverging reality.
The paper was published in the PNAS journal, notorious for publishing anything in
favour of scaremongering data with wild exaggerations on temperature rise, sea level
rise and ice melting. The paper was edited by Rahmsdorf and accepted by
Schnellnhuber, both notorious proponents for the IGCP/AGW ideas. This means that
the paper, in fact, was not peer reviewed but “pal reviewed”. Again, typical actions for
persons operating “in the pink field of nonsense” of Figure 1.
The central message from the strongly twisted statements presented by Bamber et
al. in the PNAS journal (May 2019), is, and I quote: We find that a global total SLR
exceeding 2 m by 2100 lies within the 90% uncertainty bound.
A rise in sea level by 2 m in 80 years would imply a rate of sea level rise of 25.0
mm/yr. This is far into the pink field of nonsense, way beyond the frames of realistic
sea level changes.
At the Pleistocene/Holocene boundary (11,700 BP), ice melted at a higher rate
than ever before or after during the last 30,000 years (Figure 2). And there were
huge ice caps to melt. Still, the rate of sea level rise was not more than about 10,0
mm/yr (at the most 12.5 mm/yr); i.e. 50% of what Bamber et al. now claim.
