The ‘most durable patch of snow’ in Britain, is set to melt for only the eighth time since records began in the 1700s, and it could go completely, experts predict.
Known as The Sphinx, the 13ft strip of snow at Braeriach, in the Cairngorms, is known to have survived virtually every summer since records began.
But it could become a victim of climate change, with warmer summers, wetter autumn and colder winters, causing it to get smaller, warns mountaineer and author Iain Cameron, who said ‘it is unlikely to last out the week.’
Scotland has a number of hardy snow patches, but they melt frequently. However, the Sphinx has only melted seven times in 300 years, with three in the last five years.
There are no lasting glaciers in the country, but these snow patches can last throughout the summer, clinging on until the first flurries of winter.

WHAT IS A LASTING SNOW PATCH?
A snow patch, such as The Sphinx in the Cairngorns, is a lasting strip of snow that survives the summer.
They are often at a higher altitude, with overhanging rocks to reduce sunlight.
Int he case of the Sphinx, it has only melted in the summer seven times in 300 years, re-freezing the next winter.
They have been actively studied for more than 100 years, but records of their extent started in the 1700s.
Recent years have seen the extent of these patches decline, and seen them melt more frequently.
There is concern they will disappear completely as the world warms up.
Most of these are on Ben Nevis, the highest mountain in Scotland, with others in the Cairngorms, a mountain range in the eastern Highlands of the country.
Experts are worried that its permanent demise may be imminent for all of the snow patches, including the iconic Sphinx.
Mr Cameron is Scotland’s leading snow patch expert, having studied them for decades, and written a book on their history.
He pointed out that four of its disappearances have been within the last 20 years.
‘It was thought never to melt, or at least very infrequently,’ he said, ‘but this will be the third time in five years, which is unprecedented.’
‘I’m not a climatologist but I think it’s a safe assumption to say that rising temperatures are what is ultimately behind this,’ the author added.
The Sphinx – so-called because of the rock climb directly above it – is the UK’s oldest patch of ‘permanent’ snow. and since the 1700s has melted in 1933, 1959, 1996, 2003, 2006, 2017 and 2018. With the risk of a melting this year in 2021.
Mr Cameron explained that it’s the closest thing Scotland has to a glacier and, as a result, is the most closely-studied patch of snow in the British Isles.

It can be found along the lip of the ridge of Braeriach, which is the UK’s third-highest mountain, sitting in a very isolated part of the Cairngorms.
It lies in a hollow under the mountain’s ridge, meaning it gets very little sunlight, which allows it to stay frozen, even in the heat of summer.
‘There is a lot of snow there over winter and spring, so as a result there are huge build-ups of snow on the hills which take a long time to melt,’ Mr Cameron said.
The Sphinx has been studied seriously for about 100 years and especially closely since about the 1980s, and now it is in its final days, it is a patch of its old self.

The snow of recent years has melted to expose harder, older layers which are now melting too, prompting Mr Cameron to say it now ‘looks inconsequential.’
However, despite the way it looks today, what is left ‘can tell us a lot more than we might first think,’ he explained.
‘Snow patches like this act as a barometer for what the wider climate is doing and I think that’s borne out by the evidence we are seeing.
‘Just the minimal amount of patches are surviving these days compared to how they used to. The amount of snow that falls in winter seems to be less and less, so as far as I’m concerned there’s definitely a trend taking place there.’

Each year Mr Cameron writes a paper for the Royal Meteorological Society regarding the condition of snow patches across Scotland.
‘I’m not a climatologist or even an academic, but it’s one of these strange things that when you do the research you become curiously attached to,’ he said.
‘Of course from a pragmatic point of view it doesn’t really matter at all if they melt, but from a philosophical and scientific perspective they do matter.
‘These things can tell us what is happening in the wider climate and we would be wise to pay heed to what these snow patches are telling us.
‘They are small in size but their size belies their importance.’
UK summers are to hit 104°F within the decade as scorching weather becomes our new ‘normal’
Scorching summers of 104°F (40°C) will become the UK’s new ‘normal’ by the end of the century, forecasters from the Met Office have warned.
The alarming prediction comes as experts warned that temperature and rainfall records are being smashed at a ‘shocking’ rate in Britain.
All of the UK’s top ten warmest years on record since 1884 have occurred in the last two decades, with central England now warmer than in the last three centuries.
Furthermore, the last three decades have been 1.6°F (0.9°C) warmer than the three decades that preceded them. Warming trends are evident across the while UK.
The researchers have expressed fear that the rate of global warming is spiralling out of control, saying that ‘climate change is happening and it’s happening now’.
Alongside the trend towards increasing temperatures, the UK has been on average around 6 per cent wetter over the last 30 years than in the three decades before that, with six of the ten wettest years on record occurring since 1998.
The UK’s wettest February on record struck in 2020, during which the country was battered by storms Ciara and Dennis in rapid succession, bringing devastating flooding to many homes and businesses.
In fact, most of the UK received more than twice the usual long-term average rainfall that month, with increases as high as 400 per cent seen in the Pennines and 300 per cent across broad swathes of the north and west.
Alongside 2020 providing the wettest recorded February, the last 12 years also saw the wettest April (2012), June (also 2012), November (2009) and December (2015).
