“Over the past decades, atoll islands exhibited no widespread sign of physical destabilization in the face of sea-level rise.
“88.6% of islands were either stable or increased in area, while only 11.4% contracted.
“It is noteworthy that no island larger than 10 ha decreased in size.
These results show that atoll and island areal stability is a global trend, whatever the rate of sea-level rise.”- Duvat, 2019
In other words, the Earth’s coasts gained more land area then were lost to rising sea levels.
“Earth’s surface gained 115,000 km2 of water and 173,000 km2 of land over the past 30 years, including 20,135 km2 of water and 33,700 km2 of land in coastal areas.” (Donchyts et al., 2016)
As a visual example, Ahmed et al. (2018) find that Bangladesh’s coastal land area grew by 7.9 km2 per year during 1985-2015.
“This paper draws upon the application of GIS and remote sensing techniques to investigate the dynamic nature and management aspects of land in the coastal areas of Bangladesh. … This research reveals that the rate of accretion [coastal land growth] in the study area is slightly higher than the rate of erosion. Overall land dynamics indicate a net gain of 237 km2 (7.9 km2annual average) of land in the area for the whole period from 1985 to 2015.” (Ahmed et al., 2018)
I wanted to draw the people who believe this (rising oceans) attention to a very old photograph compared to a new one to compare La Jolla (California) sea levels from 1871 to Now (REAL CLIMATE SCIENCE):
Also, Photographs show no change in Sydney sea level over the last 130 years (REAL CLIMATE SCIENCE):
Much like the “Polar Bear Scare” – Polar Bears reaching a record population since being measured, I tell my “warmist” friends that we should burn more CO2 because if we were worried about CO2 when the population was thought to be decreasing… why aren’t we lauding it as it increases?!
LIKEWISE – here is a report about the “disappearing islands due to “SEA RISE“:
“…the pair of New Zealand researchers set out to examine historical changes in 87 islands found within the Jaluit Atoll…over the period 1945-2010. During this time, the islands were subjected to ongoing sea level rise and the passage of a notable typhoon…which caused severe damage with its >100 knot winds and abnormal wave heights…caused a decrease in total island land area of approximately five percent, yet Ford and Kench write that “despite [this] significant typhoon-driven erosion and a relaxation period coincident with local sea-level rise, [the] islands have persisted and grown.” Between 1976 and 2006, for example, 73 out of the 87 islands increased in size, and by 2010, the total landmass of the islands had exceeded the pre-typhoon area by nearly 4 percent.”
Should we encourage China to build MORE coal plants? Hmmm?
An older challenge was about ANWR… and running a pipeline from Alaska to a port. Eco-fascists use to tell me that it was bad for the caribou species in the area. Then someone did a study and found the caribou population thrived as they used the pipeline to break the harsh elements. After that study came out, the challenge faded into history. But, it caused headlines that swayed public opinion… truth being hindmost in the Left’s arsenal. One last example of this statement for context:
“The scientist behind the bogus claim in a Nobel Prize-winning UN report that Himalayan glaciers will have melted by 2035 last night admitted it was included purely to put political pressure on world leaders…. Dr. Lal’s admission will only add to the mounting furor over the melting glaciers assertion, which the IPCC was last week forced to withdraw because it has no scientific foundation.” (David Rose, The Daily Mail, January 24, 2010)

JO NOVAcatches us up with the latest studies involving islans 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 a resort on, that’s about that is about ten Rugby fields. Conveniently for us, no island bigger than 10 hectares shrank despite the world adding two thousand coal fired plants and a billion cars.
See the graph. All the larger islands are staying the same size or growing.
WATTS UP WITH THAT has the abstract and the conclusion of the study. Here is the abstract:
Abstract: 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. Atoll islands affected by rapid sea-level rise did not show a distinct behavior compared to islands on other atolls. Island behavior correlated with island size, and no island smaller than 10 ha decreased in size. This threshold could be used to define the minimum island size required for human occupancy and to assess atoll countries and territories’ vulnerability to climate change. Beyond emphasizing the major role of climate drivers in causing substantial changes in the configuration of islands, this reanalysis of available data indicates that these drivers explain subregional variations in atoll behavior and within-atoll variations in island and shoreline (lagoon vs. ocean) behavior, following atoll-specific patterns. Increasing human disturbances, especially land reclamation and human structure construction, operated on atoll-to-shoreline spatial scales, explaining marked within-atoll variations in island and shoreline behavior. Collectively, these findings highlight the heterogeneity of atoll situations. Further research needs include addressing geographical gaps (Indian Ocean, Caribbean, north-western Pacific atolls), using standardized protocols to allow comparative analyses of island and shoreline behavior across ocean regions, investigating the role of ecological drivers, and promoting interdisciplinary approaches. Such efforts would assist in anticipating potential future changes in the contributions and interactions of key drivers.
