"Five islands have disappeared in the Pacific's Solomon Islands due to rising sea levels and coastal erosion, according to an Australian study that scientists said Saturday could provide valuable insights for future research.

A further six reef islands have been severely eroded in the remote area of the Solomons, the study said, with one experiencing some 10 houses being swept into the sea between 2011 and 2014.

"Scientific survey found all reefs had been affected by high sea surface temperatures, with up to 90% of coral colonies bleached in some areas".

Bleaching happens when algae that lives in the coral is expelled due to stress caused by extreme and sustained changes in temperatures, turning the coral white and putting it at risk of dying if conditions do not return to normal.

"The soup of bright-green algae that is currently blanketing Florida's Treasure Coast is a reminder for many residents of the re-plumbing of the lower half of the state over the past century, when hundreds of canals, reservoirs and other public works were built to control the flow of water as cities blossomed there."
