Century old map throws new doubt on climate change sea level claims

A new book on the history of New Zealand has inadvertently stirred the climate change debate by revealing a near zero sea level increase over the past century.

The book, The Great Divide, includes a 100 year old map of Cloudy Bay lagoons in New Zealand, drafted back in 1912 to show the location of 20 kilometres of canals dug with wooden spades by ancient Maori.

However, when the 1912 map is shown alongside a satellite image of the same location from Google Earth, it reveals not only the startling accuracy of the original map (drafted at a time when aerial photography did not exist) but also a stunning lack of Pacific Ocean encroachment on the narrow shoal linking the lagoons to the sea.

The shoal is comprised of rock and pebbles, making it an ideal weathervane for sea level increase as it’s less prone to erosion than shifting sands.

Even the narrowest and lowest part of the bar, marked with a black squiggle on the 1912 map, remains the same in 2012.

The Great Divide goes on sale this week, and among its revelations is confirmation that a massive comet-strike into the ocean off New Zealand’s southern coast caused a 220 metre high tsunami that may have been responsible for erasing evidence of human habitation in early New Zealand.

  1. Area photography did exist in 1912…. it was first used in France in 1858, and was a common practice world-wide by the 1870’s. If it wasn’t available in 1912 in New Zealand then that is what the article needs to say… because it absolutely existed when this map was drafted

  2. Why should anyone be surprised? When mega-rich elitists tell us we must radically alter our lifestyles whilst they just go on acquiring more mansions and private jets and so on, the claims of their hand-picked “experts” SHOULD seem idiotic.

    NONE of this is news to those of us who have followed this appalling global scam from the beginning. Two Climategate email scams and the sacking of CRU head Phil Jones…the list of offenses is endless. Even the Gaia crackpot Lovelock has backed off from his statements.

  3. Well that’s interesting.

    Just goes to show once again the gross over exaggeration to the point of blatant fraud much of the claims on AGW/CC and sea levels are.

    Similar findings in Australia and the USA. Tide lines no different now than they were 100yrs or more ago. Meanwhile the pushes of accelerated AGW/CC sea level rise in various UN Agenda 21 toadying Authorities around the World are making it harder for residents living next to the sea in many areas. Despite NO change in real Sea Level rises
