From emissions to concentrations

emitted greenhouse gases

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

Regional models

Four GHG emission scenarios. Alternative projections of how the future climate might evolve over the 21st century:

◦ Medium-high (also referred to as ‘Business As Usual scenario’)scenario.

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%

5km grid – better for ski resorts but no snowfall data

UKCIP08 -> UKCP09

Postponed from Autumn 2008 to early summer 2009

Dummy data have not been provided

Higher spatial and temporal resolution

Better assessment of uncertainty – two types of uncertainty

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?

Combination of climate and socio-

economic processes

Cairngorm National Park

Focus on adaptation strategy for tourism sector

Socio-economic development at national scale needs to be

considered in the development of adaptation strategy

e.g. ageing and wealthier population

Social change scenarios up to 2031

time scale for adaptation?
