Five Solomon islands disappear under rising seas, researchers find


Five tiny Pacific islands have disappeared due to rising seas and erosion, a discovery thought to be the first scientific confirmation of the impact of climate change on coastlines in the Pacific, according to Australian researchers.unRGEGtitled

The submerged islands were part of the Solomon Islands, an archipelago that over the last two decades has seen annual sea levels rise as much as 10 millimeters (.4 inch), according to research published in the May issue of the online journal Environmental Research Letters.

But six other islands had large swathes of land washed into the sea and on two of those, entire villages were destroyed and people forced to relocate, the researchers found.

One was Nuatambu Island, home to 25 families, which has had 11 houses and half its inhabitable area lost since 2011, the research said.

The study is the first that scientifically “confirms the numerous anecdotal accounts from across the Pacific of the dramatic impacts of climate change on coastlines and people,” the researchers wrote in separate commentary on an academic website.

The scientists used aerial and satellite images dating back to 1947 of 33 islands as well as traditional knowledge and radiocarbon dating of trees for their findings.

The Solomon Islands, a nation made up of hundreds of islands and with a population of about 640,000, lies about 1,000 miles northeast of Australia.


The study raises questions about the role of government in relocation planning, said a Solomon Islands official.

“This ultimately calls for support from development partners and international financial mechanisms such as the Green Climate Fund,” Melchior Mataki, head of the Solomon Islands’ National Disaster Council, was quoted as saying in the commentary.

The Green Climate Fund, part of United Nations Framework Convention on Climate Change, was founded to help countries deal with climate change.

The Solomon Islands was among the 175 nations who in April signed a global agreement reached in Paris to curb climate change.

Relocation has occurred ad hoc on the islands, the study said.

Several Nuatambu islanders moved to a neighboring, higher volcanic island, the study said. Other people were forced to move from the island of Nararo.

Sirilo Sutaroti, 94, is among those who had to relocate from Nararo. He told researchers: “The sea has started to come inland, it forced us to move up to the hilltop and rebuild our village there away from the sea.”


Climate change strikes again. A paper published in the journal Environmental Research Letters says five of the Solomon Islands have completely submerged underwater due to man-made climate change, and six more have experienced a dramatic reduction in shoreline. The Solomon Islands has a population of a little more than 500,000 people, many of whom have been adversely affected by rising sea levels in recent years. NASA scientist James Hansen estimated that seas could rise by seven meters within the next century. In 2014, Losing Ground issued a report that shows how large areas of the Louisiana coastline are being lost to rising sea levels. A 2011 study conducted by the U.S. Geological Survey determined that the state’s wetlands were being lost at a rate of “a football field per hour.” Michael Edison Hayden writes from ABC News, “The Solomon Islands provides a preview of how sea-level rise could affect other coastal communities in the coming years, according to the study, largely because the speed which erosion is taking place has been accelerated by a “synergistic interaction” with the waves that surround it.


It is located in the Northeast of the Chagos Archipelago, between Blenheim Reef and Peros Banhos. The main islands in the group are Île Boddam, with the former main settlement, and a land area of 1.08 km², and Île Anglaise (0.82 km²), both on the western rim of the reef. There were smaller settlements of Chagossians in Fouquet (0.45 km²) and Takamaka (0.48 km) Islands. Île de la Passe is 0.28 km² in area, and Île Mapou 0.04 km². The remaining islets are much smaller. The total land area is 3.56 km².

There is a passage into the lagoon, named Baie de Salomon, on the Northern side, between Île Anglaise and Île de la Passe. The Salomon Islands are one of the favorite anchoring spots for itinerant yachtsmen passing through the Chagos, even though there are no proper moorings for yachts and a permit of the BIOT authorities is needed. Now uninhabited, the islands are overrun by low jungle between the coconut trees and it is hard to find the traces of the former settlements.[2][3]
