Captured on camera: 50 years of climate change in the Himalayas

In the 1950s, the Swiss glaciologist Fritz Müller and Austrian scientist Erwin Schneider conducted among the first extensive studies of the Everest region in Nepal taking photographs of the glaciers, mountains and valleys. Fifty years later mountain geographer Alton Byers revisited the exact sites of the original photographs to take more than 40 replicates, many of which illustrate the dramatic effects of climate change in the world's largest mountain range. The photos are just a selection of those included in an exhibition Himalaya – Changing Landscapes [ ] on show at climate change talks in Bonn [ ].

Top: An very deep layer of ice covered the Imja glacier in the 1950s. Over the next fifty years, small meltwater ponds continued to grow and merge, and by the mid 1970s had formed the Imja lake. The thin cover of debris on this glacier may have accelerated surface melting, as heat is transferred to the ice below.
Bottom: By 2007, the Imja lake had grown to around one kilometre long with an average depth of 42 metres, and contained more than 35m cubic metres of water. The Imja glacier is retreating at an average rate of 74 metres a year, and is thought to be the fastest retreating glacier in the Himalayas.

Top: Taboche peak (6,367m) as seen by Erwin Schneider from the east, above the Nangkartshung monastery. Taboche, and its neighbour Jobo Laptsan (6,440m) to the right preside over the lower Khumbu valley. At their base is the path to Everest base camp. Tsholo Tso is a moraine dammed lake at the foot of Jobo Laptsan.
Bottom: Taboche seen from the same point in 2007. The clean, debris-free glaciers and ice nestled below the Taboche summit have been reduced considerably by recent warming trends. The ice in the small glaciers below the ridgelines to the right (north) has suffered the most, perhaps because of its lower altitude, below 6,000 metres.

Top: The original photographs, taped together to form a panorama of Ama Dablam (6856m) and Imja valley. They were taken from a point high above Nangkartshung monastery near the village of Dingboche on the Everest trekking trail.
Bottom: Ama Dablam and Imja valley photographed from the same point in 2007. Warmer temperatures have contributed to the recession of more than 100m of ice, seen to the left of Ama Dablam. The dramatic melting of glaciers and ice witnessed at lower altitudes is not yet seen at higher altitudes where the temperatures are much lower.

Top: Khumbu and Imja valleys as seen from the upper slopes of Taboche (6,367m) by Erwin Schneider. To the left is the pyramid shaped Pumori (7,146m) with the Khumbu glacier just below, at the head of the Khumbu valley – the gateway to the Everest base camp. The Everest massif in the next frame is dominated by the long wall of Lhotse (8,410m). Imja valley is in the middle of the panorama, the approach to Island Peak clearly visible. Ama Dablam (6,856m) appears in the fourth photo.
Bottom: Alton Byers's 2007 panorama shows how although glaciers all over the world are shrinking this is not the case everywhere. The contrast between the two images shows that global warming has not yet led to dramatic ice loss at extreme high altitudes (ie above 5,000m).

Series of before and after panoramas of Imja glacier taken five decades apart highlights dramatic reduction of Himalayan ice

Felicity Carus, Thursday 4 June 2009 17.00 BST

When Fritz Müller and Erwin Schneider battled ice storms, altitude sickness and snow blindness in the 1950s to map, measure and photograph the Imja glacier in the Himalayas, they could never have foreseen that the gigantic tongue of millennia-old glacial ice would be reduced to a lake within 50 years.

But half a century later, American mountain geographer Alton Byers returned to the precise locations of the original pictures and replicated 40 panoramas taken by explorers Müller and Schneider. Placed together, the juxtaposed images are not only visually stunning but also of significant scientific value.

The photos have now been united for the first time in an exhibition organised by the International Centre for Integrated Mountain Development [ ] (Icimod) and are printed here for the first time in Britain.

The Himalaya – Changing Landscapes exhibition opened in Bonn this week as delegates gathered ifor the next round of UN talks aimed at delivering a global deal on tackling global warming [ ]. The series of pictures tell a story not only about the dramatic reductions in glacial ice in the Himalayas, but also the effects of climate change on the people who live there [ ].

"Only five decades have passed between the old and the new photographs and the changes are dramatic," says Byers. "Many small glaciers at low altitudes have disappeared entirely and many larger ones have lost around half of their volume. Some have formed huge glacial lakes at the foot of the glacier, threatening downstream communities in case of an outburst."

His scientific results were published in the Himalayan Journal of Sciences and he is now in the Cordillera Blanca mountains in Peru where he will replicate Schneider's 1930 photos of glaciers.

"Much remains uncertain about the melting of glaciers and future water supplies," he said. "But what is certain is that by promoting the conservation and restoration of mountain watersheds we can counter many of the impacts of warming trends, by creating cooler environments, saving biodiversity and protecting water supplies."

The effects of climate change are dramatically illustrated at the world's "third pole", so-called because the mountain range locks away the highest volume of frozen water after the north and south poles.

The 1956 photograph of the Imja glacier, then one of the largest glaciers at an altitude of around 5,000m, shows a layer of thick ice with small meltwater ponds. But by the time Byers took his shot in 2007, much of the glacier had melted into a vast but stunning blue lake. Today, the Imja glacier, which is just 6km from Everest, continues to recede at a rate of 74m a year - the fastest rate of all the Himayalan glaciers.

Nepal's average temperature has increased by 1.5C since 1975 . A major UN Environment Programme report last year [ ] warned that at current rates of global warming, the Himalayan glaciers could shrink from 500,000 square kilometres to 100,000 square kilometres by the 2030s - a prediction supported by the rate of retreat seen in Byers' pictures.

Imja is one of 27 glacial lakes in Nepal classified as potentially dangerous. If the moraines which dam the lake are breached, thousands of lives in the most densely populated Sherpa valley in Nepal are at risk from flooding and landslides.

Himalayan glaciers also feed into major Asian river systems including the Ganges, Indus, Mekong and Yangtze. If glacial meltwaters turn to a trickle, widespread droughts will threaten the 1.3 billion people that depend on water flowing in those rivers .

Andreas Schild, the director general of Icimod, said the photographs reveal just "the tip of the iceberg".

"Scientific evidence shows that the effects of globalisation and climate change are being felt in even the most remote Himalayan environments," he said. "While climate change is mostly caused by the highly industrialised parts of the world, the effects are taking their toll in the sensitive mountain areas. The signs are visible, but the in-depth knowledge and data from the Himalayan region is largely missing. What happens in this remote mountain region is a serious concern for the whole world." © Guardian News and Media Limited 2010


How Fast Are Himalayan Glaciers Melting?

The U.N. Intergovernmental Panel on Climate Change goofs in predicting total meltdown by 2035. But the roof of the world is still losing its icy coat. David Biello reports

January 21, 2010

The village of Brep in Pakistan doesn't exist in the same place anymore. That's because a torrential flood forced the community to move after a lake formed by glacial meltwater burst its bounds and leveled the town.

Glacial lake outbursts have become a yearly occurrence [ ] across the high mountain region stretching from Afghanistan to Bhutan sometimes called the Roof of the World.

Such floods are now common because temperatures in this high mountain region are rising even faster than those at lower elevations [ ]. A rise in altitude of 2,000 meters equals a tripling in the increase of average temperatures. As a result, many Himalayan, Hindu Kush and Karakoram glaciers are dwindling.

Yet, predictions of the glaciers imminent demise may have been premature. The United Nations Intergovernmental Panel on Climate Change famously predicted they could disappear as soon as 2035. It turns out that guesstimate was based on misquoting a researcher in a 1999 news article [ ]—not a result from any kind of peer-reviewed scientific study [ (and again, see )].

The incident reflects a breakdown in the IPCC process [ ] but it doesn't undercut the reality that glacier loss, particularly in what are technically tropical regions such as the Andes and Himalayas, continues to accelerate in the 21st century. Though they likely won't disappear entirely for centuries, losing the glaciers will eventually be bad news for the billions around the world who rely on meltwater to survive [ ].
