 Another utterly absurd contribution from the National Trust:

A „game-changing“ new map shows the threats climate change may have on the UK’s stately homes and landscapes.

The National Trust warns the number of its sites facing a high level of threat from issues such as coastal erosion, extreme heat and flooding could rise from 5% to 17% over the next 40 years.

Its map plots a worst-case scenario where nothing is done over that time to drive down global carbon emissions.

The charity says planning for the worst will help it protect sites effectively.

The map is intended to help highlight potential future hazards in heritage or countryside sites across England, Wales and Northern Ireland.

The map shows the different potential climate change threats – including the risk of overheating and humidity

Interventions can then be made to reduce the hazards – such as planting trees to provide shade in higher temperature areas, or restoring peat bogs to prevent flooding.

The worst-case scenario shows:

  • High heat and humidity would hit the south-east of England, with a third of National Trust sites in the region experiencing at least 15 days above 30C (86F) a year
  • Storm damage, landslides and flooding would become common and more widespread, particularly in the north of England and Wales
  • Coastal erosion and flooding will increase in Northern Ireland, potentially leading to more landslides around locations such as the Giant’s Causeway

The charity wants to plant 20 million trees before 2030, and said the map will ensure trees are planted where they are needed most.

National Trust director for land and nature Harry Bowell said: „This map is a game-changer in how we face the threat climate change poses to the places we care for.

„While the data draws on a worst-case scenario, the map paints a stark picture of what we have to prepare for. But by acting now, and working with nature, we can adapt to many of these risks.“

The charity says staff are already taking action to cope with rising temperatures:

  • Heat-tolerant plants are being grown at Ham House in London, which the map warns could often face 40C (104F) heat by 2040
  • At Lyme Park in Cheshire, which was hit by a major flood in 2019, trees are being planted on moorland to slow the flow of water and reduce flooding risks
  • At Mount Stewart in County Down, where rising sea levels have contributed to coastal erosion, a shelter against incoming water has been made
  • At Malham Tarn, in the Yorkshire Dales, where a 18th-Century barn collapsed due to soil shrinkage, teams will plant trees and use specific plants to manage the water table

The map plots the impacts of extreme heat and humidity, landslides, coastal erosion, shrinking and shifting ground due to wet and dry conditions known as „soil heave“, and high winds, in 2020 and 2060.

Note the words “could”, “worst case scenarios”, and a map without any data to back it up.

Let’s take a few of the nonsensical claims:

.

 1) High heat and humidity would hit the south-east of England, with a third of National Trust sites in the region experiencing at least 15 days above 30C (86F) a year

There is no trend towards hot days becoming more frequent in England, or in the south east in particular (Rothamsted):

At Rothamsted, there have been 102 days of 30C and over  going back to 1916. In the last decade there have been 15 days.

2) Storm damage, landslides and flooding would become common and more widespread, particularly in the north of England and Wales

The example of Lyme Park in Cheshire is given, which received 19mm of rain in one day, so let’s look at Buxton, about 20 miles away:

None of the indicators suggest that rainfall is becoming more extreme. Buxton is high up in the Peak District, so rainfall totals would be much higher usually. However Shawbury, 40 miles south in Shropshire is comparable to Lyme Park, and daily rainfall totals of 19mm are commonplace there.

3) At Malham Tarn, in the Yorkshire Dales, where a 18th-Century barn collapsed due to soil shrinkage, teams will plant trees and use specific plants to manage the water table

Evidently 18thC barns have never fallen down before! However data shows that Malham is not getting drier.

Malham is located on a limestone plateau, so the soil would naturally drain quickly.

4) Coastal erosion and flooding will increase in Northern Ireland, potentially leading to more landslides around locations such as the Giant’s Causeway

The nearest tide gauge is across the St Georges Channel, at Millport in Scotland. Sea levels there are rising at just 1.6mm a year, but are no higher now than at the start of the record in 1970.

The Giants Causeway is reckoned to be 50 million years old. The idea that 2 inches of sea level rise is going destroy it is absurd.

Clearly the National Trust have money to burn. Maybe they should contribute some of it instead to the bill for Net Zero.
