Heat isn’t just annoying anymore.
It is deadly.
The UK’s independent Climate Change Committee (CCC dropped a hard truth on the table recently. If the world keeps warming at its current trajectory hitting 4C by the end of the century we could see up to 18,00 heat-related deaths in the UK annually. Parts of Wales? They aren’t safe. Disease-carrying mosquitoes will arrive.
The message for Wales’s new government is stark. Act now. Or face the consequences.
The new normal is brutal.
2025 was Wales’s warmest summer on record. But it wasn’t even the peak. We hit 37.1C at Hawarden in 2023? No wait 2022. Let’s keep that date sharp in memory. Ten hottest years on record all happened since the early 00s. The old rhythms are gone.
Hot summers are becoming standard.
Heatwaves lasting a week or more? Common by 2050. Without intervention excess deaths will jump from roughly 1400-3000 yearly to 3000-10000. If we fail to cut greenhouse gases those numbers skyrocket even higher. It’s not a prediction of doom. It is math.
Hospitals need air conditioning. Care homes do too. Schools need it. Shutters. Blinds. Trees. Basic shading.
The CCC wants a maximum workplace temperature mandate. Protect the workers.
“It makes it bearable.”
That was Sandra Evans talking. She runs Bryn Seiont nursing home in Caernarfen. They have AC in communal areas. She calls it lucky. Without it she says residents get agitated distressed. Some homes restrict window opening so staff are trapped inside with the heat.
She plans ahead. Others? Maybe not.
Water and fire everywhere.
Flooding risks hit 245000 Welsh properties. Winter rain gets worse. Sea levels rise. It’s a double threat.
Coal tips loom over landscapes. The report praises recent Welsh efforts to register disused tips and manage them but the threat of landslide remains real. Drought meets extreme wet weather creates a perfect storm for farmers. Food production suffers. Wildfires get longer hotter more intense.
Fire crews are stretched.
Sion Slayaker of Mid and West Wales Fire and Rescue sees the change. Floods are more severe. Wider area. More resources needed. Wildfires? Longer duration higher intensity.
Gareth Tovey of the Fire Brigades Union puts it bluntly.
“We are significantly concerned that these incidents will push the service past breaking point.”
He wants more money. More prep. His members are on the front line. Not in some future year right now.
A missed window.
Shea Buckland-Jones of WWF Cymru says current Welsh plans are simply not fit for purpose.
There is a window open for the new government. First 100 days. Set the tone. Prioritize nature action.
Derek Walker the Future Generations Commissioner used stronger language. He said ignoring storm-proofing while we still can constitutes mass negligence.
The CCC updated advice from five years ago. Baroness Brown chair of the adaptation committee notes that lives landscapes homes are under pressure. The spokesperson added they hope the government finds benefits in acting. The Welsh government says they are committed to a resilient future.
Commitment is easy to promise.
The data doesn’t lie. The temperatures are rising. The fires burn hotter.
So what happens when the next heatwave hits and the AC is the only thing between comfort and chaos?
Or when the rain won’t stop falling.
The choice sits with them now.
