IMG_9748.CR2Kiribati has tide gauge data going back to the 1940’s.  Compliments from PSMSL (Permanent Service for Mean Sea Level) based in Hawaii.  The two Canton Island gauges in Kiribati run from 1949 to 2007. They also overlap for 2 years, giving a decent comparison, and that difference is fairly consistent over the overlapping time period to produce a single record.

Tide Gauge 575 = 1949 to 1974

Tide Gauge 1329 = 1972 to 2007

I have spliced the two records, adjusting one by the average monthly difference, to produce a long record.

Now, there are not many tide gauges in the world that do not have some spurious readings, but over a long enough record you should be able to see a decent trend, if there is one.  In this case, the less than half a mm per year is hardly anything to panic over.

Splicing in Kiribati’s other tide gauge data to complete the record for gaps and to bring it up to date, results in a 1.52mm per year sea level rise over Kiribati’s recorded tide gauge history (1949 to 2012).

This is also consistent with the 1371 and 1804 Kiribati combined tide gauges (1974 to 2012). The 1804 gauge is still in use.

This rate of sea level rise is almost exactly what we have seen in tide gauge records for 200 years, long before any C02 influence, and certainly the coral Islands can cope exceptionally well with this rate of rise.

Probably the most knowledgeable person on the planet regarding ocean level would have to be Dr Nils-Axel Morner. So, what does he have to say?

The sun is starting to set on the doomsayers of “climate change”.
