Nearly a fifth of National Trust sites could be at "high risk" over the next 40 years due to climate change.
In a worst case scenario in which carbon emissions aren't lowered, up to 47,888 sites could be at medium-to-high risk of flooding, landslides, coastal erosion and extreme heat and humidity.
The National Trust aims to become carbon net zero by 2030 and considering how its buildings and collections can be protected from extreme weather.
Harry Bowell, the National Trust Director for land and Nature said the data "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."
