Risk occurs when there is a combination of climatic hazard, over an exposed natural or human system that is also vulnerable (i.e. shows sensitivity). In order to assess the climate change risk for the different natural and human systems, we followed a multi model approach (i.e. several GCM runs) . The risk is assessed comparing current climate (1980-2010) and future climate conditions (2035- 2065 under RCP 8.5).

Climate change risks maps for communicatinginformation about climate impacts were develop forcontinental Chile, as well as Juan Fernandez and Easterislands. These maps incorporate current and futureclimate projections, specifying hazards, exposure andsensibility for selected systems (i.e. Human Settlement/heat wave, Hydrology/drought) at municipal level.

For each unit, and for each valid climate-hazard/system,risk will be obtained as the product of climate threat,exposure and sensitivity. The municipal risk can besubsequently aggregated at provincial and regionallevels.

The maps will be displayed in a web-based platform thatallows dynamic visualization and data downloading, thusbecoming an important tool for the design of publicpolicies and the implementation of adaptationmeasures.

A GIS spatial database is under development, containingthe characterizations of the current and future climatescenarios and the projections for the different climaterelated threats for each systems of interest. Exmpls ofthese are: floods (heavy rains), droughts, heat waves,frosts and changes in the isotherm. All the results will beuploaded to a flexible public platform that will bedeveloped and then transfer to the Ministry ofEnvironment. It is expected to be a dynamic tool,identifying gaps and integrating new information inorder to constantly improve results and decisionmaking.
