Scully pointed to the tangible threats already affecting gardens, moorland, and historic structures under National Trust management. “Climate change isn’t a thing that’s happening out there to other people, it’s actually impacting ourselves and the places we love. The threat is tangible,” he explained, noting that the last two summers have brought the reality home to both staff and visitors.

Extreme weather patterns now pose multiple dangers to heritage sites across the trust’s portfolio. Heavy rainfall can overwhelm drainage systems and penetrate historic walls, causing damp conditions and structural erosion that threaten centuries-old buildings. Repeated cycles of wetting, drying, freezing, and thawing damage stonework through expansion and contraction, while flooding undermines the foundations that have supported these structures for generations.

Hotter, drier conditions present equally serious challenges, increasing the risk of subsidence as soil composition changes and raising the danger of wildfires that could devastate historic landscapes and buildings. The combination of these climate pressures creates what conservation experts describe as an unprecedented threat to Britain’s built heritage.

Planning for Worst-Case Climate Scenarios

The National Trust is now undertaking comprehensive planning to prepare for more extreme weather by examining what could happen to the properties and landscapes it manages over the next 40 years. “We’ve got to think about what could be the worst possible outcome and then work backwards from that,” Scully said, describing the organization’s new approach to long-term conservation strategy.

At Fountains Abbey, adaptation measures could include increasing drainage capacity and expanding gutters to handle heavier rainfall events that exceed the capacity of centuries-old water management systems. Such infrastructure changes require careful balance between preserving historic authenticity and ensuring structural survival in a changing climate.

The trust’s response may also result in visible changes to garden aesthetics that challenge traditional visitor expectations. Scully acknowledged the organization needs to be “more open to how we would adapt,” with gardens potentially becoming “less manicured” as water conservation and climate-resilient planting take priority over formal historical recreation.

“People expect things to look perfect and crisp,” he said, recognizing that shifting public expectations will form a crucial part of the conservation challenge. The trust must balance historical accuracy with practical adaptation while maintaining the visitor experience that generates revenue for ongoing conservation work.

Coastal Properties Face Greatest Pressure

The National Trust looks after properties including Beningbrough Hall, Nunnington Hall, and Treasurer’s House in York, as well as miles of coastline stretching from Loftus to Filey. Coastal sites face some of the greatest climate pressures, with erosion and rising sea levels threatening both natural landscapes and historic structures built when shorelines occupied different positions.

A National Trust spokesperson confirmed the organization’s conservation approach must evolve with changing conditions. “Climate change is affecting many of the places we care for, and our conservation work has to evolve with it,” they stated, outlining a framework that considers multiple factors when making difficult decisions about resource allocation.

Conservation decisions will weigh the historical significance of a place, the benefit it brings to people, and whether proposed approaches remain sustainable over the long term. This framework suggests some sites may receive priority treatment while others face managed decline or transformation as resources prove insufficient to protect everything equally.

Funding Challenges Complicate Adaptation

The financial reality of climate adaptation adds another layer of complexity to the conservation challenge. As a charity receiving no guaranteed government funding, the National Trust must rely on membership fees, donations, and competitive grant applications to public bodies and lottery funds for major projects.

Scully acknowledged that some adaptation processes could be “very expensive,” without providing specific cost estimates for the work required across the trust’s extensive portfolio. The funding gap between available resources and necessary climate adaptation work may ultimately determine which sites receive protective investment and which face transformation or partial abandonment.

The organization’s warning reflects a broader reckoning within the heritage sector as climate change forces difficult choices about what can be saved and what must be allowed to change. Traditional conservation philosophy emphasized preserving sites exactly as they were, but accelerating climate pressures make that approach increasingly untenable for many locations.

Shifting Conservation Philosophy

The National Trust’s acknowledgment that it may not be able to save everything marks a philosophical shift with implications beyond individual properties. Heritage organizations worldwide face similar pressures as extreme weather events increase in frequency and intensity, forcing painful decisions about resource allocation and conservation priorities.

The trust’s evolving approach suggests a future where dynamic conservation replaces static preservation, with historic landscapes and gardens adapting to new climate realities rather than attempting to maintain historical snapshots. Such changes will require significant public education as visitors adjust expectations about what heritage sites should look like in an era of climate change.

The organization manages hundreds of historic properties across England, Wales, and Northern Ireland, with millions of visitors annually contributing to local economies while connecting with Britain’s cultural heritage. The challenge now facing conservation professionals involves maintaining that connection while honestly communicating the impossible choices climate change forces upon heritage management.
