West Wales scientists to test if snow is melting high on Everest
RESEARCHERS plan to test if the snow high up on Everest is melting, threatening the water supplies of over one billion people.
Despite air temperatures being well below zero on the highest mountain on Earth, it is believed that the snow may be melting due to rising air temperatures combined with intense solar radiation.
If the theory proves correct, it would suggest that the glaciers in the Himalayas are thawing faster than expected.
Glaciers in the highest mountains of the planet are an extremely important source of water with over one billion people – including many in India, Pakistan and Bangladesh – depending on Himalayan runoff.
Changes in the rate of glacier thawing would threaten this water supply. Another danger would also be more flooding from failures of natural ice dams, or so-called Glacial Lake Outburst Floods.
The new project follows previous findings by Aberystwyth University and University of Leeds researchers which showed that the temperature of the ice in the lower parts of Khumbu Glacier, at the foot of Mount Everest, is warmer than would be expected given the local air temperature.
As part of the research, Professor Bryn Hubbard from Aberystwyth University will work with Professor Duncan Quincey of the University of Leeds to lead a team to the Western Cwm, over six kilometres above sea level and half a kilometre above base camp.
The researchers expect to go on their first trip in spring 2025 to drill into the surface of the upper reaches of Khumbu Glacier and use the boreholes to record temperatures. The team will also install automatic weather stations at the study sites.
This data will help them look for evidence of melting and refreezing within the glacier’s surface snowpack.
Professor Bryn Hubbard from Aberystwyth University’s Department of Geography and Earth Sciences said:
“It may well be a bit of a surprise to many that snow is melting within the mountain’s Western Cwm, but it is increasingly likely and it needs to be investigated and measured if we are going to be able to identify the effects of climate change on this water-stressed region and beyond.
“Understanding and recording what actually happens inside these glaciers is critical to developing computer models of their response to anticipated climate change. Equally important is developing a better understanding of how they flow so that we can better predict when dams that form on these glaciers are likely to be breached, releasing destructive volumes of water to the valleys below. This is a real risk in the Himalayas as it is in other regions such as the Andes and has the potential to endanger the lives of thousands of people.”
Scientific observations are rarely made at high altitudes because of the logistical challenges in transporting equipment.
The team is designing a new lightweight drilling setup to overcome these barriers. However, it will still face problems such as maintaining battery power in freezing temperatures and working in areas with harsh living conditions and low levels of oxygen.
Professor Duncan Quincey explained:
“Our previous work has relied on helicopters to transport our equipment onto the glacier, but given how thin the air is in the Western Cwm, we can’t be sure the helicopters will be able to fly this time. We also won’t know quite how the equipment will fare in such harsh conditions, because it is designed to operate in much warmer conditions – as could also be said for the human body! But if we can successfully drill even a single borehole within the Western Cwm, that will be a major success. Most importantly, it will lead us to being able to model how water supplies are likely to change for a large part of the world’s population with much greater certainty.”
Professor Hubbard added:
“This work will also give us a new understanding of processes and changes that are relevant for all glaciers in similar settings world-wide. Hopefully, it will resolve outstanding debates about the possibility of net mass loss at the world’s highest elevations and indicate the extent to which other glaciers within the Himalayas may also contain unexpectedly warm ice.
“We should also be able to provide insights into a rarely observed cryospheric zone that can inform public policy on climate change. As part of this, we will be providing further evidence for supporting agencies such as the United Nation’s Development Programme, and the Nepalese government. This should help them prepare for, and mitigate against, a now inevitable change in meltwater supply as climatic changes continue to influence the region.”
The project is funded by the Natural Environment Research Council and is a collaboration between academics from Aberystwyth and Leeds universities.

Wales eyes £47 billion in renewable energy investment by 2035
WALES is on the cusp of a £47 billion renewable energy investment wave that could transform its economy, create thousands of jobs, and breathe new life into communities. This promising outlook was unveiled today at the Future Energy Wales 2024 conference at Newport’s ICC, showcasing preliminary analysis by BiGGAR Economics on the economic potential of renewable energy across the nation.
Commissioned by RenewableUK Cymru, in partnership with Solar Energy UK and Marine Energy Wales, the study highlights the substantial economic gains Wales could achieve by meeting its renewable energy targets across onshore wind, offshore wind, solar, and tidal power.
The research projects an average annual investment of nearly £4 billion, reaching a peak of £7 billion by 2028. Offshore wind alone is expected to attract £32.4 billion, forming the foundation of Wales’ economic growth through 2035. However, capturing this opportunity requires an effective industrial strategy and substantial port infrastructure upgrades to support thousands of new, high-quality jobs.
While offshore wind presents long-term growth, onshore wind offers Wales a rapid boost, with a potential £4.5 billion in investments enabling an increase to over 3 GW capacity by 2035, contingent on addressing planning and grid capacity challenges.
The NESO 2030 Clean Power report underscores the need for grid reform to expedite renewable energy across the UK, but Wales remains hampered by immediate planning resource shortages.
The latest data from the 2024 Welsh wind power report shows a surge in renewable project interest, with Wales’ pipeline expanding by 18% this year, from 9 GW in 2023 to over 10.5 GW in November 2024, largely due to new onshore wind projects. However, with current deployment rates, Wales is forecast to contribute only 5% of the UK’s total wind capacity by 2035—well behind Scotland’s 64 GW target.
RenewableUK Cymru’s Call for Strategic Support
Jess Hooper, Director of RenewableUK Cymru, said:
“Wales stands at the threshold of a historic opportunity. By harnessing this renewable investment potential, we can secure Welsh jobs and build a robust, long-term local economy. But achieving this vision requires strong, immediate support from both the UK and Welsh governments.
“We urge a coordinated, four-nations approach to accelerate wind deployment and grid upgrades. With strategic investment in grid capacity and planning, wind energy can become central to Wales’ clean energy future—delivering real benefits for our climate, economy, and communities.”
£47 Billion Equals 208 Principality Stadiums
Nikki Keddie, Director at BiGGAR Economics, added:
“The scale of Wales’ renewables potential is extraordinary. The £47 billion needed to reach our targets is equivalent to building 208 Principality Stadiums. Investment in renewables will boost energy security, employment, industrial growth, and rural development.
“To maximise economic benefits, it’s crucial to dismantle barriers to project delivery and create opportunities for local businesses to capture value. We look forward to the next phase of this report, where we will detail the economic share Wales can secure.”

Huge new facility at Pembroke Power station approved
A GREEN hydrogen fuel production facility by Pembroke Power Station has been approved by Pembrokeshire planners, despite a concern raised about the amount of water it will take from the county’s Llys y Fran reservoir.
An application by Pembroke RWE Generation UK plc for the construction of a green hydrogen production facility, with associated works including a water supply pipeline to the Pembroke Power Station and electrical supply connection to the National Grid Substation on land adjacent to Pembroke Power Station, was recommended for conditional approval at the November meeting of the county council’s planning committee.
Green hydrogen is produced from water, in an electrolysing process using electricity obtained from renewable sources; the electrolyser site previously occupied by the power station’s sports and social club.
A report for planners stated: “The electrolyser is planned to be powered with ‘low carbon electricity supplied primarily via grid connected renewables’ and will create ‘green hydrogen’ for use in industrial processes. Water for the electrolyser will come from existing power station supplies.
“The pipeline corridor would supply hydrogen gas to the Valero Refinery. The pipeline corridor would follow the route of an existing natural gas pipeline. Most of the pipeline corridor would be underground, passing across farmland and a wooded area. It will emerge above ground within the Valero Refinery. The working width of the construction area for the pipeline is expected to be approximately 30m.”
Some of the final details are subject to potential change, members heard, but the maximum height of the flare stack would be 25m and the electrolyser building and compressor building would be up to 17m in height.
The report also quoted the applicant: “By bringing together technologies such as hydrogen production, carbon capture and storage, battery storage and floating offshore wind to the Pembroke area, RWE can help to decarbonise the energy sector in Wales for generations to come. RWE’s ambitions will build on Pembrokeshire’s local energy heritage, safeguarding existing jobs at the development site, while delivering a significant local economic investment and creating new jobs throughout construction and operation.”
Speaking at the November planning meeting, project development manager Zoe Harrison told members would make “a significant contribution to net zero,” the green fuel leading to approximately 90,000 tons less of Carbon Dioxide being produced a year, the equivalent of 18,000 cars being taken off the road.
Cllr Steve Alderman, who said he was in support of the proposal, raised the issue of the amount of water the facility would take from the Llys y Fran reservoir to produce two tons of hydrogen fuel per hour, members hearing nine kilos of water was needed for every kilo of hydrogen fuel produced by the electrolysing process.
Zoe Harrison said the water was available through an existing agreement with Welsh Water, and a suggestion by Cllr Alderman to look at desalinating seawater was not part of the current scheme but could potentially be looked at in the future.
Moving approval, Pembroke Dock councillor Brian Hall said: “I’m sure everybody does realise this is a very important project for Pembrokeshire full stop,” adding: “I can’t emphasise enough how the people in my area can’t wait for this development.”
Fellow Pembroke dock councillor Tony Wilcox also supported the proposal, saying of concerns about potential visual impacts: “To a certain extent, that horse has bolted, because it’s in the middle of a power station.”
Members unanimously supported delegated approval for the application.
The facility is expected to take 24 months to build, an earlier consultation on the scheme said, and could be built by early 2027.
