LONGYEARBYEN, Norway (AFP) –
UN chief Ban Ki-moon on Wednesday urged world leaders to act now to halt global warming, as he saw first-hand its effects in the Arctic ahead of a key climate change summit in December.
The UN will organise a high-level international meeting in New York on September 22 to prepare for the Copenhagen summit.
In Copenhagen, world leaders will try to seal a new accord to fight climate change after the Kyoto Protocol requirements expire in 2012.
"I will tell world leaders that this is the time to act before it is too late," Ban told reporters during a visit to Norway's Svalbard archipelago, just 1,200 kilometres (745 miles) from the North Pole.
"The Arctic is similar to sending a canary into a coalmine -- this is a danger warning for the global climate," he said.
If world leaders fail to "take urgent action ... we will regret it deeply for the future of humanity and the future of the world," he added.
His comments came a day after he visited the Ny-Aalesund climate change research station in Svalbard and took a walk on the polar ice rim, saying he was "very much alarmed" by the rapid rate of melting ice.
Researchers studying atmospheric conditions in the Arctic had told him Tuesday that they had over the past two years suddenly seen a large increase in emissions of methane gas, one of the most aggressive greenhouse gases that contributes to global warming.
"This Arctic is the place where this global warming is happening much faster than any other region in the world. It looks like it's seemingly moving in slow motion but it's moving faster and faster. Much faster than expected," Ban said Tuesday.
Norwegian Environment Minister Erik Solheim, who accompanied the UN secretary general on his tour of the Arctic region, echoed Ban's concerns.
"There is absolutely no doubt of the challenge facing the world today. Hundreds of thousands of people will die if we don't act," he told a seminar attended by Ban at Longyearbyen University in Svalbard.
"The magnitude of the task is enormous," he added.
Speaking to AFP, Ban criticised world leaders for often acting in the interests of their own countries.
"Climate change affects everyone. It doesn't respect borders. So political leaders should act as world leaders," he said.
Earlier Wednesday, Ban toured a vault carved into the Arctic permafrost, filled with samples of the world's most important seeds in case food crops are wiped out by a catastrophe.
"The world faces many daunting challenges today, one of the greatest of which is how to feed a growing population in the context of climate change," a bundled-up Ban told reporters after he visited the site.
"The seeds stored here in Svalbard will help us do just that. Sustainable food production may not begin in this cold Arctic environment, but it does begin by conserving crop diversity," he said.
Aimed at safeguarding biodiversity in the face of climate change, wars and other natural and man-made disasters, the seed bank has the capacity to hold up to 4.5 million batches of seeds, or twice the number of crop varieties believed to exist in the world today.
The vault was inaugurated in February 2008, and so far some 25 international and national institutes from 22 countries have deposited some 400,000 batches of seeds, according to the Norwegian government.
Ban was to leave the Arctic later Wednesday.
