And what theory this time? - Sea level rise is already starting to flood island nations - There are few legal precedents for how these nations can exist without dry land. - Island states need to act now if they want to preserve even their ocean territories. And the debunker? A new geological study has shown that many low-lying Pacific islands are growing, not sinking. The islands of Tuvalu, Kiribati and the Federated States of Micronesia are among those which have grown, because of coral debris and sediment. The study, published in the magazine the New Scientist, predicts that the islands will still be there in 100 years’ time. However it is still unsure whether many of them will be inhabitable. Prognosis ‘incorrect’ In recent times, the inhabitants of many low-lying Pacific islands have come to fear their homelands being wiped off the map because of rising sea levels. But this study of 27 islands over the last 60 years suggests that most have remained stable, while some have actually grown. Using historical photographs and satellite imaging, the geologists found that 80% of the islands had either remained the same or got larger – in some cases, dramatically so. They say it is due to the build-up of coral debris and sediment, and to land reclamation. Associate Professor Paul Kench of Auckland University, who took part in the study, says the islands are not in immediate danger of extinction. “That rather gloomy prognosis for these nations is incorrect,” he said. “We have now got the evidence to suggest that the physical foundation of these countries will still be there in 100 years, so they perhaps do not need to flee their country.” Does it make me a bad person that stories like this, putting pie in the face (once AGAIN) of the Global Warmists, makes me happy? My only defense? It’s a ‘Gotcha’ classic. *winks*

Pacifik: Raste razina mora, ali rastu i otoci Novo istraživanje dalo je neočekivane rezultate – iako se razina mora podiže, površina nekih otoka se ne smanjuje Unatoč klimatskim promjenama i podizanju razine mora, brojni pacifički otoci su se u posljednjih 60 godina povećali, pokazuje studija objavljena u britanskom časopisu "New Scientist". Znanstvenici Paul Kench sa Sveučilišta Auckland i Arthur Webb s Fijija, za potrebe istraživanja usporedili su satelitske snimke ukupno 27 otoka od 1950-ih do danas i ustanovili da samo četiri otoka tone. "Njih 23 zadržalo je svoju veličinu ili se proširilo. U posebno ugroženoj državi Tuvalu, gdje kopno ni na jednom mjestu ne leži više od 5 metara iznad razine mora, primijetili smo da je se dam od devet otočića koji čine državu poraslo, a jedan se povećao za čak 90%", objašnjava Kench. Podaci su iznenađujući jer je istovremeno razina mora u tom razdoblju porasla 12 centimetara. Sličan fenomen zabilježen je i na Kiribatiju. Otoci su navodno veći jer su sastavljeni od koraljnog otpada koje more i vjetar nanose s okolnih grebena. Kako su koralji živući organizmi, oni se neprestano umnožavaju i tako stvaraju novi materijal koji otocima osigurava rast. Pretpostavlja se tako da je uragan Bebe 1992. na Tuvalu donio 140 hektara novog sedimenta zbog čega se površina otoka povećala 10%. "Moramo naglasiti da promatrani otoci predstavljaju samo mali dio otoka koji postoje u Pacifiku. Međutim, očito je da porast razine mora ne ugrožava sve otoke. More raste, a otoci na to reagiraju", tvrdi Kench.
