Sea Level scare industry urges plans to panic and evacuate over 1mm rise

Please, sell us your low lying land

Let’s play sea level bingo with the latest advertising from the Merchants of Sea-level Scares.

Hitting the media outlets tonight — the latest “Prepare to Die” news stories claim we must plan now for evacuees, refugees, inundation and homeless koalas. All the usual features of marketing are there — firstly all the images they use are from mocked up futuristic sea level rise. Secondly, it’s not a continuation of current trends, it a sudden acceleration — in this case from 1mm to year to 9mm a year, effectively starting tomorrow.

1 tiny millimeter

From 1969 – 2013 the seas have not changed the beaches around these Tuamotu atolls — or almost any other atoll you can name.

By every method known to man, seas are rising around 1mm a year:

1,000 tide gauges, hundreds of studies of beaches, satellites measuring sea levels, and satellites measuring beaches.

All anyone needs to know about sea levels is that for the last 50 years sea levels have been rising at 1mm a year as shown by a thousand tide gauges all over the world. There was no acceleration. (Beenstock et al). Some of those gauges [...]

Rising seas? Hundreds of Pacific Islands are growing, not shrinking

This should end all the Pacific Island climate claims right here. A new study of over 700 islands for decades shows that even though seas are rising faster than any time in the last million years, somehow no islands with people on are shrinking. This means there are no climate change refugees from any vanishing island. Plus it’s more proof that highly adjusted satellite data is recording sea levels on some other planet.

Over the past decades, atoll islands exhibited no widespread sign of physical destabilization in the face of sea-level rise. A reanalysis of available data, which cover 30 Pacific and Indian Ocean atolls including 709 islands, reveals that no atoll lost land area and that 88.6% of islands were either stable or increased in area, while only 11.4% contracted.

Look how closely these researchers are tracking the shores. Below on Tuamoto, French Polynesia, scientists can tell you that islets 12 and 14 (see pic) have disappeared since 1962. So we can track roving blobs of sand about 20 to 30 meters across.

No habitable island, none, got smaller:

The researchers reckon that 10 hectares is about the smallest island you’d want to plonk [...]

Climate change creates free real estate in Tuvalu: “climate refugees” can all go home

The Green Blob is going to have to get rid of satellites. Real data is so inconvenient.

For years many people called scientists have assumed, like any smart 5 year old would, that islands are fixed blobs of rock and sand that just sit there and sink as oceans rise. Now satellite images show that three quarters of the islands in Tuvalu are growing rather than shrinking.

Total land area is up 2.9%. Total government funded scientists who predicted reality, down 97%.

Since our emissions helped create nearly a square kilometer of free real estate in Tuvalu, it seems only fair that they return any climate funds, and pay a royalty.

The whole of Tuvalu is 26km2 and about 10,600 people live there. Total GDP is $32 million. It’s a cheap marketing tool. In May last year, despite Tuvalu being used as an advertising posterchild for climate change for years, it had not received funding from the Green Climate Fund. In August 2017 UNDP finally promised $38 million. That’s theoretically an extra income equivalent to 20% of their GDP for the next seven years. No wonder these islanders are keen to talk “climate change”.

Scientists who have [...]

Rising sea-levels in the Indian Ocean due to man-made “adjustments” not CO2

PMSML stands for Permanent Service for Mean Sea Level, though there is nothing permanent about sea-level data — like all obedient climate change data, it’s subject to change fifty years later – and the adjustments are as large as the trends.

We’ve seen this pattern in so many places. Now Cliff Ollier and Albert Parker have shown it in the Indian Ocean looking at Aden in Yemen, and Mumbai in India (and other places, and other data). Kenneth Richard at No Tricks Zone goes through it at length. James Delingpole calls it TideGate. The New York Times says nothing (just like last time).

Parker and Ollier conclude that at Mumbai, apparently the sea levels were “perfectly stable over the 20th century”. At Aden, sea levels trends are rising at a pitifully small quarter of a millimeter a year during the twentieth century. (And that’s their upper estimate). The lower estimate is minus five hundreths of a millimeter a year. Looking at other sites as well they estimate a rise of …”about zero mm/year” in the last five decades. zero.

This, they say, agrees with other things like… coastal morphology, stratigraphy, radiocarbon dating, archaeological remains, and historical documentation. (But not [...]

Kiribati sinking “like Titanic” but 59 million times slower

Kiribati, with a natural resource base of almost nothing, makes 15% of its nominal GDP, via donations from the Australian government. Periodically Mr Anote Tong, president of Kiribati,visits Australia to remind us how much they need help money.

Creatively, this year, Mr Tong is comparing Kiribati’s future to the sinking of the Titanic.

Give the man points for theatrix:

“We are the people who will be swimming,” he said. “The question will be — will those people on the lifeboats bother to pull us in or push us away because we would be too problematic?”

Kiribati’s highest point is 13m above water, and is sinking at a rate of 1mm a year (see the updated graph below by Eyes On Browne). To rephrase Euan Mearns, at this rate, complete inundation of it will take 13,000 years.

The Titanic’s elevation (waterline to the deck) was 18m, so it was 50% higher, yet it sank in 2 hours 40 minutes. That’s one ninth of a day, or one 3,285th of a year. Conservatively, the comparative speed works out to be 42.7 million times faster. Allowing for the higher elevation (but discounting funnels and/or palms) that would be 59.1 million times [...]

Real sea level rise: a lost continent called Zealandia submerged

File this under Nasty Nature. This is the sort of thing planet Earth throws at life.

The is real “sea level rise” — where most of a continent (called Zealandia) sinks under the waves — and — as far as we know, though I could be wrong — fossil fuel use was minimal circa 50 -80 million years ago. Can Exxon be blamed?

New Zealanders may be feeling a bit cheesed that they carelessly lost something like 80% of their land. (Call that “Old Zealand” which was once as big as India.) Given that it is one kilometer underwater, it looks like it isn’t coming back soon. But think of all the national parks, reefs, etc that were destroyed?

The story is that the Pacific Rim of Fire “buckled” 40-50 million years ago, and Zealandia sunk a lot deeper. There is a suggestion that it was originally submerged about 80 million years ago (or so), when this renegade land split from Australia and Antarctica.

Since 1,000 tide gauges estimate current sea level rise at around 1 mm a year, real climate change puts the current panic about sea levels into perspective. Even the next ice [...]
