The NZCSC has been trumpeting the arrival in New Zealand of professor (emeritus) Nils-Axel Mörner, “a leading world authority on sea levels and coastal erosion”. Prof Mörner’s mission? To reassure us that sea level rise is not happening. Mörner first takes the ritual swipe at An Inconvenient Truth:
I can assure you there have been no rises in sea levels, so you should ask yourselves how much else of what Gore says is similarly false?
That’s all right then. We can ignore all the current work on sea level rise and just take his word for it. He then explains why Tuvalu is increasingly being flooded by king tides:
There have been some problems with erosion from recent cyclones and salt water intrusion on Tuvalu. It seems that Japanese owned pineapple plantations have extracted too much freshwater from the ground, causing an inflow of sea water and destruction of the underground freshwater reservoirs.
Pineapple plantations? I thought the problem was with “borrow pits”, holes created by the US armed forces when they built the runway during WW2 (and sea level rise). Prof Mörner likes his pineapple theory enough to have used it a fewtimes, but the only other source I can find is on über-crank Ken Ring’s web site, which — to be candid — doesn’t fill me with hope. Anyone know where this particular delusion came from?
Meanwhile, someone who does know something about sea level rise — and who, like Hansen, is concerned that the IPCC AR4 view is a little conservative is Stefan Rahmstorf, who’s visiting CSIRO in Australia:
“This isn’t just my concern: there’s a number of scientists who were not very happy with the impression given in the summary of the report that sea-level rise projections had dropped compared to the previous report,” Professor Rahmstorf told the Heraldwhen he arrived in Sydney.
