The Aleutions and adjacent landmass are actually sinking. It always helps to unite cause with effect, rather than hysteria.
The Pacific tectonic plate rubs against the North American plate, giving rise to the San Andreas and Denali strike-slip faults. In southwestern Alaska, those two plates meet head on, and the Pacific plate sinks beneath the North American plate. In this subduction zone, some of the ocean plate melts and the molten rock pushes to the surface in a string of 40 active volcanoes, forming the Aleutian Islands.


Catalina Island off California has sunk each decade for more than a million years by at least two millimeters, according to research by Stanford Uni.
The UN had been premature in declaring the villagers on Tegua (Solomons) to be climate change refugees when a large earthquake caused the island to shoot back out of the water in 2009. That island sank nearly 12 centimeters (five inches) between 1997 and 2009
Vanikoro, also in the Solomons, is sinking by seven millimeters (0.3 inches) a year.Earthquakes and tsunamis strike Vanikoro regularly, but people here are at the mercy of the forces of nature in a longer-term way, as well: On its slowly sinking course, the Australian Plate is dragging Vanikoro along into the depths.
Further confusing the issue is the fact that "sea level increase" is not uniform. It is reputedly higher in the Pacific. Like most inhabitants of the South Pacific, those of Vanikoro must contend with sea-level fluctuations of some 20 centimeters (eight inches) caused by currents in the Pacific, such as the climate phenomenon called El NiƱo.
CO2 represnts 0.04% of the atmosphere and the anthropogenic component of that 0.04% is reckoned to be 0.4%

Does 4 parts per million of anthropogenically generated CO2 really have the impact suggested? . Water vapor varies by volume in the atmosphere from a trace to about 4% and is also a potent greenhouse gas.
Do the maths. CO2(Human) 4 parts per million
             Water Vapour up to 40,000 parts per million

The Intergovernmental Panel on Climate Change (IPCC) Third Assessment Report suggests that MSL may rise by approximately 50 cm in the next 100 years, and that regional meteorology may also change, which would affect the magnitude and frequency of storm surges
I may win the lottery. That is not science, it is not even worthy of being labelled a forecast.
