The National Fund monitors the “worst-case” climate impacts on heritage and landscapes

The mapping tool describes the threats posed by climate impacts, including extreme heat, humidity, landslides, high winds and floods, and how they may change by 2060.

Its map is based on a “worst-case scenario” to reduce failed carbon emissions over the next several decades, and it aims to be a reporting tool to highlight potential risks in a heritage site area.

It reveals that without action on emissions, the number of National Trust Fund sites in regions most threatened by climate impacts could more than triple, from 3,371 (5%) to 11,462 (17%) over the next 40 years.

The number of sites with a high or medium risk of climate-related risk could increase from 20,457, or 30% of sites, to 47,888, or 71%, by 2060.

Identifying vulnerable areas will help the National Trust to identify places that may require interventions such as tree planting or restoring peatlands to maintain or slow water flow to prevent floods, or more. Shade to protect vulnerable areas from high temperatures.

The charity said the card would ensure, as part of a pledge to plant or create 20 million trees to combat climate change, that the trees will go where they are most needed.

The map shows that high temperatures and humidity will hit southeast England, with a third of National Trust sites in the area experiencing at least 15 days above 30 ° C (86 ° F) annually, and storm damage, landslides and floods will become common and more widespread, especially In northern England and Wales.

Coastal erosion and flooding will increase in Northern Ireland, which could lead to more landslides around sites like the Giant’s Causeway.

“This map is a game-changer in how we deal with the threat that climate change poses to the places we care about,” said Harry Powell, director of the National Trust for Land and Nature.

“While the data is based on a worst-case scenario, the map paints a stunning picture of what we need to prepare for.

“But by acting now and working with nature, we can adapt to many of these risks.”

The National Trust is working in partnership with government agencies to map all UK cultural heritage sites and unveil the map ahead of major UN climate talks in Glasgow to catalyze international action on climate change – which, if successful, will avert the worst cases. Scenario. on the map.

The fund says employees are already taking action to deal with rising temperatures, such as at Ham House in London, which could often experience temperatures of 40 degrees Celsius (104 degrees Fahrenheit) by 2040, as heat-tolerant plants and hours of work are grown in them. The park has changed to begin with. And finish early to avoid the summer afternoon heat.

In Lyme Park in Cheshire, which was hit by major floods in 2019, the team is planting trees on swamps to slow the flow of water and reduce flood risks.

In Mount Stuart, Northern Ireland, where sea level rise at Strangford Lough has contributed to coastal erosion, the parking lot has been relocated and a protection belt is created from incoming seawater.

In Malham Tarn, Yorkshire Dales, a healthy 18th-century barn collapsed due to shrinking soil, but crews can now intervene with moves such as planting trees and using some plants to manage the water table.

Dyffryn Mymbyr in Snowdonia, a 16th-century terraced farmhouse in Wales, was protected from the influence of increased heavy rainfall by installing “hanging panels” at the exposed end of the building.

The map depicts the effects of extreme heat and humidity, landslides, coastal erosion, and soil shrinkage and displacement due to wet and dry conditions called “land venting” and high winds. , In 2020 and 2060.

It takes data from a number of sources and places it in hexagonal, 5 km networks across England, Wales and Northern Ireland.

The National Trust also shares available flood data with staff at flood-prone properties and actions that can be taken, but the information is too local to be included on the map.
