A once-permanent patch of snow in the Highlands has melted for the fourth year in a row – for the first time in recorded history.
The repeated melting of the Sphinx, a snow patch on the UK’s third highest mountain, Braeriach in the Cairngorms, is attributed to climate change. Records show it has melted 11 times since the 1700s, and that in the 20th century it melted on three occasions – 1933, 1959 and in 1996.
So far during the 21st century, it has melted eight times in 24 years. This year it has melted for the fourth year in a row – the first time this has happened since records began, with the ice patch described as a “barometer for climate change”.
The Sphinx, a remnant of the last Ice Age, was given its name in the 1940s due to the rocks surrounding it on Garbh Choire Mor. Citizen scientist Iain Cameron, 51, from near Stirling, has monitored it closely for 20 years.
He visited on Thursday and said the patch measured around 0.5m – and will have melted overnight. He described it as “like visiting an elderly relative”, having seen it measure between 2m and 50m in previous years.
Mr Cameron said: “The Sphinx is a vestige of the last Ice Age. It is the place in Scotland where glacial regeneration will occur.
“Importantly, we can see that patches of snow which lasted through decades and centuries are dispersing. These patches of snow act as barometers for climate change.
“I’m not a scientist or climatologist, I’m just someone who writes about these things. It makes me feel sad – I’m used to seeing them survive.”
On the reasons for the melt, he added: “There have been far fewer western-facing storms from the Atlantic. There’s not as much snow falling in winter. We don’t get as much snow as we used to get, precipitation is mostly rain.”
The ice patch was initially monitored in the 1840s by the Scottish Mountaineering Club. In 1933 a letter was written to The Times newspaper noting that it had melted for the first time in living memory, by a cohort of mountaineers whose lived experience dated to the mid-1800s.
In 2003 and 2006, it vanished, and it did so again in 2017 and 2018. Scotland was hit by the Beast from the East in 2018 but it did not benefit the Sphinx as it is eastern-facing. Since 2020, the patch has vanished every year.
Mr Cameron wrote a book about his enthusiasm for snow, The Vanishing Ice, in 2021, and said he initially felt the title was pessimistic – but he now feels it was accurate.
