'Sinking' Pacific nation is getting bigger: study |
2018-02-10 |
![]() A University of Auckland study examined changes in the geography of Tuvalu's nine atolls and 101 reef islands between 1971 and 2014, using aerial photographs and satellite imagery. It found eight of the atolls and almost three-quarters of the islands grew during the study period, lifting Tuvalu's total land area by 2.9 percent, even though sea levels in the country rose at twice the global average. Co-author Paul Kench said the research, published Friday in the journal Nature Communications, challenged the assumption that low-lying island nations would be swamped as the sea rose. "We tend to think of Pacific atolls as static landforms that will simply be inundated as sea levels rise, but there is growing evidence these islands are geologically dynamic and are constantly changing," he said. Can any prediction of global warmists survive examination? |

#5 This is definitely a sign of global warming. Like a wool sweater in a hot dryer, global warming is making the Earth shrink. This causes islands like Tuvalu to be more exposed and hence larger. It's Science, bitches! |

#3 Atolls and reefs are former volcanic islands. Over time erosion and other natural forces wash all that volcanic soil into the ocean and the islands shrink. It has nothing whatsoever to do with global warming or rising sea levels. Hopefully the hot spots under the earth's crust at the bottom of the ocean create new volcanoes and new islands as tectonic forces pull the older islands away from the hot spot. The Hawaiian Islands are prime examples. The southwestern most island in the chain, the Big Island, is currently home to two active volcanoes and one of these has been in a constant state of eruption since 1983. Kilauea has been pouring lava down its slopes and into the ocean since then and making the island bigger as it does so. To the northeast, past Kauai and Niihau, are a series of smaller reefs and atolls that were at one time millions of years ago probably as big as the Big Island but have since been eroded to their current state. |

#2 I hope the growth is evenly balanced. The Hank Johnson 'tip-over' factor should not be discounted. |
