Future climate change scenarios for much of the UK suggest that the key stone decay controlsof temperature and moisture input will change. Seasonality in precipitation is projected toincrease, essentially meaning that winters are due to become wetter, while summers are likelyto become drier. For building stones, this translates into longer ‘time-of-wetness’ periodsduring winter that are linked not simply to surface wetness, but specifically to ‘deep wetting’.Data from sandstone test walls in the wet west of...
