It's created using ArcGIS mapping from ESRI.
"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.
