Turkey's glaciers fall victim to climate change
A mountain guide for 15 years, Ozdemir then turned toward the torrent carrying dozens of blocks of ice below a slope covered with grass and rocks -- a sign of glacier loss being exacerbated by global warming. "You can see that there are quite a few pieces of glacier in the water right now... the reason why the waterfalls flow lushly actually shows us how fast the ice is melting," he said. The glaciers of Mount Cilo, which rises to 4,135 meters in the province of Hakkari on the Iraqi border, are the second largest in the country behind those of Mount Ararat (5,137 meters ) -- 250 kilometres (155 miles) further north. As global temperatures rise amid human-caused climate change, new sections of the mountains that were once capped in ice are melting fast year after year. Turkey, which is experiencing heatwaves and drought, even registered a record temperature of 50.5C on Friday in Silopi, some 200 kilometres (120 miles) from Hakkari. "The melting process is faster than we expected. According to our research, in the last 40 years, we lost almost 50 percent of this continuous snow and ice cover in this place," said Onur Satir, a professor at Yuzuncu Yil University and specialist in geographical information systems in the eastern province of Van. -'No way to cover the ice'- "Some places melt faster than other places, so actually it's showing us which places must be protected but we have no opportunity to cover the whole ice area," Satir said. In recent years, several glaciers in the Alps have been covered with white tarpaulins in an attempt to delay their demise. According to the United Nations, glaciers in several regions of the world will not survive the 21st century, threatening the water supply of hundreds of millions of people. The surrounding landscape is a delight for hikers, many of whom have flocked to the Hakkari mountains since the guns fell silent in recent years in the region, where fighters from the Kurdistan Workers' Party (PKK) have long challenged the Turkish state. The ongoing peace process with the PKK listed as a terror group by Turkey and its Western allies suggests that tourism will accelerate in the area, which became a national park in 2020. -'Don't walk on the ice'- But melting ice has made certain areas dangerous. In July 2023, two hikers were killed when they were swept away by a block that broke off from a glacier. "People should not walk on the ice," Ozdemir warned, voicing concerns about the safety of hikers and the preservation of glaciers. "This region is 40-50 kilometres away from the city, but there was no road in the past. Now, with the construction of the road, more vehicles are coming here and the increase in the number of people coming here actually accelerates the melting a little bit," said the 38-year-old guide. A UN report on desertification worldwide estimates that 88 percent of Turkey's territory is at risk: rainfall is expected to decrease by 30 percent by the end of the century, while temperatures are expected to rise by 5 to 6C compared to the averages recorded between 1961 and 1990.

Swiss glaciers face ‘alarming' early melt as tipping point arrives in July
GENEVA, July 5 — The snow and ice accumulated last winter by Switzerland's glaciers has already melted away, a monitoring service said, with Friday marking the alarming second-earliest arrival on record of the tipping point known as glacier loss day. All further melting between now and October will see the size of glaciers in the Swiss Alps shrink, according to Glacier Monitoring in Switzerland (GLAMOS). This century, the tipping point, on average, has been reached in mid-August—itself already bad news for the nation's 1,400 glaciers, which are shrinking at a staggering rate. Its arrival several weeks earlier on July 4 is 'another alarm call', GLAMOS chief Matthias Huss told AFP. 'It's like the glaciers are shouting out: 'We're disappearing. Help us.'' Glaciers in the Swiss Alps began to retreat about 170 years ago. The retreat was initially modest but in recent decades, melting has accelerated significantly as the climate warms. The volume of Swiss glaciers shrank by 38 percent between 2000 and 2024. Summer of destruction 'If we have a glacier loss day, it means that the glacier is losing mass,' said Huss. 'For a glacier that is healthy, the day would occur at the end of September, or in October—or not at all'. With no glacier loss day, the summer would simply melt away only the snow that accumulated over the previous winter. This would be 'the ideal case—a glacier in equilibrium with the climate', said Huss. Its arrival on July 4 means that 'critically, we have the whole summer left to destroy the ice'. 'Moving this day forward by five to six weeks before the normal date over the last 20 years means we're just prolonging this mass loss season dramatically,' he said. The assessment is made using 12 reference glaciers. Last winter saw low levels of snowfall, and June was the second warmest on record, contributing to the day's early arrival this year. In data going back to 2000, the only time that the tipping point arrived even earlier was in 2022, when it came on June 26. 'That was really a game-changer for us glaciologists because it was the first year when we saw absolutely extreme melting. 'Everything that we knew before about glacier melting changed,' said Huss. Experts thought 2022 was a complete outlier and although a warming climate meant other such years would be coming down the line, they did not expect to see the next very early glacier loss day coming so soon afterwards. Feedback effect Huss noted that extreme melting produces an accelerating feedback effect, worsening the situation even further. Once the reflective white snow coverage from winter is gone from the top of the glacier, the darker, more absorbent grey surface of the bare ice is exposed. 'With the same amount of solar radiation, we can now melt more ice,' Huss said. With the European heatwave over the past week and the possibility of further heatwaves in July and August, 'it is very like that again it is a very bad year for Swiss glaciers', he said. Melting glaciers threatens the long-term water security for millions of people downstream who rely on them for fresh water. Much of the water that flows into the Rhine and the Rhone, two of Europe's major rivers, comes from the Alpine glaciers. — AFP
