This document summarizes climate change projections for the Cairngorms National Park region in Scotland. It discusses how climate models are used to project impacts under different emissions scenarios. Key findings include increasing winter precipitation but decreasing summer precipitation and snowfall by 2050. Temperature is projected to increase by 1.5°C on average by 2050 under a medium-high emissions scenario. The document also describes plans to develop a community-led adaptation strategy for the tourism sector in the region to address climate change vulnerabilities.

5. Global and regional models
General circulation models (GCMs) of the atmosphere and ocean
simulate the response of the climate system to increased
concentrations of greenhouse gases in the atmosphere

14. 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%

17. 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?
