In an appeal to mark world mountain day on Saturday, the UN Environment Programme, experts and people from Switzerland, Bhutan and Canada warned that climate change was already changing their landscape, livelihoods and sapping water supplies.

"I'm convinced that unless we as individuals but also governments wake up and do something about it, I'm afraid that for my two boys there will be not much left to ski or to climb," said Patrick Z'Brun, a mountain climber and winemaker in southwestern Switzerland's Valais region.

Over the past decade, his grape harvest has forward a month to September with the warming climate, while water supplies have dwindled.

Z'Brun, who has scaled more than 500 peaks worldwide including Mount Everest, said melting snowfields and permafrost were also changing the game for climbers, who were left with crumbling rock in the summer climbing season.

"Many routes I climbed over the past 25 years can't be climbed any more or only in a different season," he said.

Lam Dorji, of Bhutan's Royal Society for the Protection of Nature, said melting glaciers and changing temperatures in the Himalayas had increased threats such as glacial lakes, and soil erosion in the east of the country.

"People used to have springs close to their communities. These have dried out and people have to move further to fetch water," he explained.

Mountains cover 20 percent of the earth's surface and are home to just 10 percent of the world's population but half of humanity depends on freshwater water from mountains, according to UNEP.

"While the international community continues to be deadlocked in its efforts to negotiate a new climate deal... UNEP wants to remind the world that the consequences of higher increase in temperature would be devastating for mountains, for the services they provide and for the large population who depend on them," said UNEP Europe director Christophe Bouvier.

A UN report released in Cancun, Mexico on Tuesday warned that mountain glaciers were melting fastest in southern South America and Alaska and communities urgently needed to adapt.

Negotiators have voiced hope that the climate talks between 190 countries would iron out differences to reach by Friday a limited accord.

UN International Mountain Day is being marked by a meeting in the upmarket Swiss Alpine resort of Verbier, organised with a community group -- the Verbier GPS association -- that is trying, with local authorities, to cut emissions in the fast expanding village.

Verbier's 3,000 strong year-round population swells about tenfold over the winter with the the arrival of holidaymakers, many from Britain, hungry for snow clad slopes.

But Verbier GPS association co-chair Marinah Embiricos said over the past seven years the snow line has receded with warming, no longer allowing prized skiing to the chalet doorstep.

"The bread and butter is in the tourism industry. This place would not exist if it continues the way it is," Embiricos said.

The OECD estimated in 2006 that two-thirds of all ski resorts in the Alps could go out of business in the coming decades as the snow line moves higher, harming a 50 billion euro (60 billion dollar) revenue stream.

Climate talks make progress as Bolivia for more
Cancun, Mexico (AFP) Dec 9, 2010 - The world's climate negotiators on Thursday inched toward compromise on fighting deforestation and assisting poor nations as Bolivia's firebrand leader demanded more aggressive action.

With one day left for the UN-led talks in Mexico, South African President Jacob Zuma urged the more than 190 nations to set up "the building blocks" for a comprehensive climate deal when he leads next year's meeting in Durban.

"We dare not lose this opportunity," Zuma told reporters at the talks in resort city of Cancun.

The negotiations are working on a framework for fighting climate change after 2012, when the requirements for wealthy nations to cut greenhouse gas emissions under the Kyoto Protocol run out.

China, while toning down its public statements, opposes a treaty that legally binds it to fight climate change. Japan has led opposition to EU calls to extend the Kyoto Protocol, saying it is unfair as it does not include top polluters China and the United States.

In late-night talks, conference watchers said the European Union, Costa Rica and small island states vulnerable to climate change offered a joint compromise under which the Cancun talks would agree to work toward a binding deal but leave discussion of its form -- Kyoto or a new framework -- to Durban.

Amid the deadlock on a treaty's form, negotiators reported progress on several other key areas including how to assist poor countries worst hit by climate change and on curbing deforestation, a leading cause of climate change.

But Bolivian President Evo Morales, who has emerged as a leading critic of the UN-led talks, demanded more far-reaching action.

"If we here throw the Kyoto Protocol into the garbage dump, we would be responsible for economy-cide, for ecocide -- indeed, for genocide -- as we would be harming humanity as a whole," Morales said from the podium of the conference, receiving loud applause.

Morales, Bolivia's first indigenous leader, called for an agreement that protects native populations and called for climate assistance to poor countries at a level "equivalent to the budget that developed countries spend on defense, security and warfare."

Wealthy economies -- including the European Union, Japan and the United States -- have pledged to help provide 30 billion dollars in near-term assistance to poor nations, along with 100 billion dollars a year in the future.

Negotiators said they saw steady progress in setting up the architecture of a future climate fund. A remaining sticking point is whether to include a role for international bodies, such as the World Bank, in administering aid.

Jeremy Hobbs, executive director of the anti-poverty movement Oxfam International, praised the proposal under discussion, including its mention of a role in protecting the rights of women.

"There is still plenty to improve," Hobbs told reporters. "But at least it was negotiated in good faith and there has been progress."

Hobbs hoped that the final proposal would require that 50 percent of aid go toward helping developing nations adapt to climate change. Nations may otherwise be able to meet pledges in other ways such as offering technical know-how on green energy.

Another area of progress is on deforestation, with the talks finalizing guidelines on how wealthy nations would assist developing nations in preserving tropical forests -- which play a vital role in the ecosystem by counterbalancing industrial pollution.

The Cancun talks have focused on incremental progress, one year after the ambitious Copenhagen summit ended in widespread disappointment.

China, which was stung by foreign criticism over its role in Copenhagen, has taken a fresh public approach in Cancun by pledging flexibility.

But its stance apparently has limits. Norway, a major player in climate negotiations, said Beijing has refused to negotiate with it in Cancun due to the awarding of the Nobel Peace Prize to jailed Chinese dissident Liu Xiaobo.
