One clear bright day last winter, a tidal surge swept over an ocean embankment here in the remote, low-lying island country of Kiribati, smashing through the doors and windows of Betio Hospital and spewing sand and debris across its maternity ward.
Beero Hosea, 37, a handyman, cut the power and helped carry frightened mothers through the rubble and water to a nearby school.
For years, scientists have been predicting that much of Kiribati may become uninhabitable within decades because of an onslaught of environmental problems linked to climate change. And for just as long, many here have paid little heed. But while scientists are reluctant to attribute any specific weather or tidal event to rising sea levels, the tidal surge last winter, known as a king tide, was a chilling wake-up call.
Pacific island nations are among the world’s most physically and economically vulnerable to climate change and extreme weather events like floods, earthquakes and tropical cyclones, the World Bank said in a 2013 report.
Before it is too lateWhile world powers have summit meetings to negotiate treaties on how to reduce and mitigate carbon emissions, residents of tiny Kiribati, a former British colony with 1,10,000 people, are debating how to respond before it is too late.
Much of Kiribati, a collection of 33 coral atolls and reef islands scattered across a swath of the Pacific Ocean about twice the size of Alaska, lies no higher than 6 feet above sea level. The latest climate models predict the world’s oceans could rise 5 to 6 feet by 2100. The prospects of rising seas and intensifying storms “threaten the very existence and livelihoods of large segments of the population,” the government told the UN in a report last year. Half of the 6,500-person village of Bikenibeu, for instance, could be inundated by 2050 due to sea-level rises and storm surges, according to a World Bank study.
Apocalyptic detailThe study lays out Kiribati’s future in apocalyptic detail. Causeways would be washed away, crippling the economy; degraded coral reefs, damaged by warming water, would allow stronger waves to slam the coast, increasing erosion, and would disrupt the food supply, which depends heavily on fish supported by the reefs. Higher temperatures and rainfall changes would increase the prevalence of diseases like dengue fever and ciguatera poisoning. — New York Times News Service
