Summary of climate change projections

   Predicted climate, in general terms, suggests increasingly wetter winter
    half year and drier summer half year. Predicted temperature changes
    are for progressive warming over the next 100 years.
   Assuming a ‘Business-As-Usual’ scenario by 2050, annual temperature
    is expected to be approximately 1.5 C warmer on average


   Precipitation is projected to increase in the winter, but decrease in the
    summer months


   For snowfall, the model projections are provided for the months of
    December, January, and February only. By 2050, snowfall is projected
    to decrease by 44%, 40%, and 40% respectively, during those three
    months. Seasonally, the decrease in snowfall will be 41.5%

Further analysis using local data

   Climate change and tourism
     Cairngorm skiing industry and its ability to adapt to a changing
       climate
        Viability of snow-based tourism not a simple function of winter
           temperature
            Winters may be milder but wetter and therefore when
             snowfall occurs there may be greater amounts falling
            Wind direction – changes in frequency of winds that
             encourage distribution towards the pistes during snowfall
             events?

   Tourism climatic index
