With the BCCVL, you can investigate the distribution of a species under potential future climatic conditions. The Climate Change Experiment takes the results of your Species Distribution Modelling experiment, and projects that distribution for a certain year in the future with the climate information from one of several climate models. Select one of several greenhouse gas emissions scenarios to influence the climate models. Future climates are available from 2015 to 2085.
Note: You will need to run a Species Distribution Model before you can run a Climate Change Experiment.
How to run a Climate Change experiment in the BCCVL
- At the top of the page click on the Experiments tab
- Under the secondary experiments heading click on Climate Change Experiment.
Step 1: Description tab
- Enter the name for your experiment in the first box (e.g. Future fox (Vulpes vulpes) distribution)
- (optional) You can also add a description of your experiment in the box below if you want to convey more information. Some researchers use this box to record their research question or hypotheses for later referral.
- Click Next.
Step 2: Source Model tab
- Click Select SDM Experiment.
- Select the species distribution model with which you would like to do your climate change projection and click Select Experiment.
- Check the box for the algorithm/s with which you would like to use.
- Click Next.
Step 3: Projection tab
- To search for and select future climate data click on Select Future Climate Data.
- In the pop-up box you can filter options such as emission scenario and general circulation model using the search functions in the left hand column, or simply by scrolling.
- Select chosen datasets - you can pick as many as you like. Click Add Layers.
- Click Next.
NOTE: The data associated with the future climate projections include:
- 18 GCMs for each emission scenario;
- 9 emission scenarios – 5 representing SRES scenarios and 4 representing RCP scenarios;
- 8 time points into the future (10 year intervals from 2015 to 2085); and
- 19 bioclimatic variables, including annual min, mean and max temperature, precipitation, sea surface temperatures, wet-day frequency, vapour pressure and cloud cover. Full list available at http://www.worldclim.org/bioclim.
- For assistance in identifying the scenarios and GCMs best suited for your species/experiment we recommend using the Climate Futures Tool.
Step 4: Run tab
- Ensure you are happy with your experiment design.
- If all tabs are green then your experiment is ready to go.
- Click Start Experiment.
- If any of your tabs are red, revisit and ensure you have filled in each component correctly.
