My data includes changing and unchanging variables.  The unchanging variables are slope and soil texture.  Although soil texture may change in the next 80 years, it is extremely difficult to predict in what way it will change, and so I have used the same texture data for past and future analysis.  The changing variables are temperature and precipitation, with the data taken from the National Centre for Atmospheric Research (NCAR) 

 

NCAR 

The past temperature and precipitation data was obtained from a 20th Century Historical Climate run.  Data was collected for June, July and August for each year from 1990-1999

The future temperature and precipitation data was obtained by running an A2 Scenario Model for each month June, July and August for each year from 2090 to 2099 

As climate models are imperfect representations of actual processes, the model uses the practice of ensembling, so that a range of possibilities are included

 

Characteristics of the A2 scenario: "high population growth, medium GDP growth, high energy use, medium-high land use changes, low resource (mainly oil and gas) availability, slow pace and direction of technological change favoring regional economic development" (NCAR)
