MALE (Reuters) - The Maldivian president and ministers held the worlds first underwater cabinet meeting on Saturday, in a symbolic cry for help over rising sea levels that threaten the tropical archipelagos existence. Aiming for another attention-grabbing event to bring the risks of climate change into relief before a landmark UN climate change meeting in December, President Mohamed Nasheeds cabinet headed to the bottom of a turquoise lagoon. Clad in black diving suits and masks, Nasheed, 11 ministers the vice-president and cabinet secretary dove 12 feet, 8 inches to gather at tables under the crystalline waters that draw thousands of tourists to $1,000-a-night luxury resorts. As black-and-white striped Humbug Damselfish darted around a backdrop of white coral, Nasheed gestured with his hands to start the 30-minute meeting, state TV showed. We are trying to send our message to let the world know what is happening and what will happen to the Maldives if climate change isnt checked, a dripping Nasheed told reporters as soon as he re-emerged from the water. The archipelago nation off the tip of India, best-known for luxury tropical hideaways and unspoiled beaches, is among the most threatened by rising seas. If UN predictions are correct, most of the low-lying Maldives will be submerged by 2100. Nasheed and the ministers used a white plastic slate and waterproof pencils to sign an SOS message from the Maldives during the 30-minute meeting. We must unite in a world war effort to halt further temperature rises, the message said. Climate change is happening and it threatens the rights and security of everyone on Earth. World leaders will meet in Copenhagen to hammer out a successor agreement to the 1997 Kyoto Protocol, and industrialised nations want all countries to impose sharp emissions cuts. We have to have a better deal. We should be able to come out with an amicable understanding that everyone survives. If Maldives cant be saved today, we do not feel that there is much of a chance for the rest of the world, he said. The developing world wants rich countries to shoulder most of the burden, on the grounds they contributed most to the problem. Nasheed and the cabinet trained for two weeks and were assisted by professional divers to pull off his latest eye-catching move related to climate change. Nasheed, barely a month after entering office last year, declared he would establish a sovereign fund to relocate his countrys 350,000 people if sea levels rise, but later admitted it was not feasible given the state of the Maldivian economy. Earlier this year, he vowed to make the Maldives carbon neutral within a decade by switching to renewable energy and offsetting carbon emissions caused by tourists flying to the Maldives.
