Five small islands that are part of the Solomon Islands cluster in the Pacific have just been submerged by rising sea levels. The sinking islands represent the first concrete evidence of climate change’s effects in the Pacific.

More islands will be subject to the same fate sooner rather than later. In recent studies, scientists have found that the global sea level will rise nearly twice what they originally predicted, increasing by over 6 feet by 2100, displacing some 13 millions in the U.S. alone.
