Wales Must Enhance Climate Adaptation Measures, Warns UK Climate Committee
Wales' new government faces calls to strengthen preparations against lethal heatwaves, droughts, and flooding, according to the UK's independent advisers on climate change.
The Climate Change Committee (CCC) emphasized the necessity for cooling solutions in hospitals and care homes, alongside increased investment in flood defenses and stabilization of coal tips.
The Fire Brigades Union cautioned that escalating flooding and wildfires risk overwhelming emergency services, while Wales' Future Generations Commissioner described failure to prioritize adaptation to extreme weather as "mass negligence."
The Welsh government affirmed its commitment to enhancing the nation's readiness for climate impacts.
Rising Temperatures and Heatwave Projections
Wales recorded its warmest summer on record in 2025, following the hottest day ever in 2022, when temperatures reached 37.16C in Hawarden, Flintshire.
The ten hottest years on record have all occurred since the early 2000s.
The CCC report states that hotter summers will become the "new normal," with heatwaves lasting at least a week becoming common by mid-century.
Without improved protection for vulnerable populations, annual excess heat-related deaths across the UK are projected to rise from the current 1,400-3,000 to between 3,000 and 10,000 by 2050.
If global warming is not limited through greenhouse gas reductions, these numbers could increase substantially.
With a 46C rise by 2100, heat-related deaths could reach up to 18,000 annually in the UK, and parts of Wales may become hospitable to disease-carrying mosquitoes, the report warns.
Cooling strategies in healthcare settings, care homes, and schools are recommended, including air conditioning, use of shutters and blinds, and tree planting to provide shade.
The report also urges the UK government to establish a "national maximum temperature for workplaces" to safeguard workers and encourage cooling measures.
Care Home Challenges During Heatwaves
Sandra Evans, manager of Bryn Seiont Newydd nursing home in Caernarfon, highlighted the benefits of air conditioning in communal areas.
"It makes it bearable for our residents, because it can be really, really difficult [during a heatwave]," she said.
"I've worked in other homes where there's no air conditioning unit and residents would become agitated and more distressed," she explained, noting restrictions on window openings.
She expressed concern about future hotter summers due to climate change, stressing the importance of planning and preparation.
"You've got to plan ahead and make sure you have all your provisions in place."
Flooding and Environmental Risks
Flooding remains a significant threat in Wales, with 245,000 properties already at risk from intensified winter rainfall and rising coastal sea levels.
Coal tip landslides are also a concern, though the report acknowledges recent Welsh initiatives to create a register of disused tips and establish an authority to oversee their safety.
A combination of drought and extreme wet weather is expected to challenge farmers and impact food production, while wildfire seasons in Wales are projected to lengthen and intensify.
These developments are anticipated to increase pressure on emergency services such as fire brigades.
Emergency Services Under Strain
Sion Slaymaker, head of emergency response at Mid and West Wales Fire and Rescue Service, stated that climate change is already significantly affecting operations.
"What we're seeing is that the flooding is more severe, it affects a wider area and demands a greater resource allocation from ourselves. With wildfires, we've seen a significant increase in their duration and intensity," he said.
Gareth Tovey of the Fire Brigades Union in Wales emphasized the frontline role of its members in the climate crisis.
"We're significantly concerned that these incidents are going to push the service past breaking point," he said, calling for increased investment.
Calls for Government Action and Criticism of Current Plans
Shea Buckland-Jones of WWF Cymru criticized Wales' existing climate adaptation strategies as inadequate.
"The report makes clear that Wales' current plans for addressing climate change are not fit for purpose," he said.
He described a "critical opportunity" for the new Welsh government to set priorities on climate and nature action within its first 100 days.
"There was a critical opportunity for the new Welsh government to really set the tone in its first 100 days...and prioritise climate and nature action," he added.
Future Generations Commissioner Derek Walker remarked that Wales is not adapting to climate change at the necessary scale and speed.
"It would be mass negligence if we continue to ignore the need to stormproof while we have the chance," he said.
CCC Report and Government Response
The CCC's report updates its previous advice from five years ago regarding climate change impacts on the UK and informs risk assessments and planning across the nations.
Baroness Brown, chair of the CCC's adaptation committee, highlighted the increasing pressures on lives, landscapes, and homes due to climate change.
"Our lives, our landscapes and our homes are under increasing pressure from the changing climate," she said.
However, she emphasized a hopeful message.
"The solutions already exist, and proven technologies are available now to help the UK adapt effectively. With the right decisions and actions, we can protect the people and the places we love," she added.
The Welsh government acknowledged the CCC's report as providing clear advice on climate risks and adaptation steps.
"We welcome its message that we must be hopeful and realise the benefits of action despite the serious challenges ahead," a spokesperson said.
"We are committed to improving our nation's preparedness for climate impacts and know that by acting now, we can build a fair, climate-resilient future for Wales."
