JAKARTA: Many of Indonesia’s islands may be swallowed up by the sea if world leaders fail to find a way to halt rising sea levels at this week’s climate change conference on the resort island of Bali.

Doomsters take this dire warning by Indonesian scientists a step further and predict that by 2035, the Indonesian capital’s airport will be flooded by sea water and rendered useless; and by 2080, the tide will be lapping at the steps of Jakarta’s imposing Dutch-era Presidential palace which sits 10 km inland.

The Bali conference is aimed at finding a successor to the Kyoto Protocol, which expires in 2012, on cutting climate warming carbon emissions.

With over 17,000 islands, many at risk of being washed away, Indonesians are anxious to see an agreement reached and quickly implemented that will keep rising seas at bay.

Just last week, tides burst through sea walls, cutting a key road to Jakarta’s international airport until officials were able to reinforce coastal barricades.

“Island states are very vulnerable to sea level rise and very vulnerable to storms. Indonesia ... is particularly vulnerable,” Nicholas Stern, author of an acclaimed report on climate change, said on a visit to Jakarta earlier this year.

Even large islands are at risk as global warming might shrink their land mass, forcing coastal communities out of their homes and depriving millions of a livelihood.

The island worst hit would be Java, which accounts for more than half of Indonesia’s 226 million people. Here rising sea levels would swamp three of the island’s biggest cities near the coast — Jakarta, Surabaya and Semarang — destroying industrial plants and infrastructure.

“Tens of millions of people would have to move out of their homes. There is no way this will happen without conflict,” Environment Minister Rachmat Witoelar said recently.

“The cost would be very high. Imagine, it’s not just about building better infrastructure, but we’d have to relocate people and change the way people live,” added Witoelar, who has said that Indonesia could lose 2,000 of its islands by 2030 if sea levels continue to rise.

Environmentalists say this week’s climate change meeting in Bali will be crunch time for threatened coastlines and islands as delegates from nearly 190 countries meet to hammer out a new treaty on global warming.

Several small island nations including Singapore, Fiji, Kiribati, Tuvalu and Caribbean countries have raised the alarm over rising sea levels which could wipe them off the map. The Maldives, a cluster of 1,200 islands renowned for its luxury resorts, has asked the international community to address climate change so it does not sink into a watery grave.

According to a UN climate report, temperatures are likely to rise by between 1.1 and 6.4 degrees Celsius and sea levels by between 18 cm and 59 cm this century.
