Strategies and technologies for adapting to climate change in particular locations should ideally be grounded in knowledge of the future climatic conditions in those locations. Estimates hold that 70% of future climates already exist somewhere in the world. That is where the analogues approach comes in.
Using global climate projection data from multiple models, the climate analogues tool developed by CGIAR Research Program on Climate Change, Agriculture, and Food Security (CCAFS) takes climate and rainfall predictions for a particular site and searches for places with similar conditions at present.
In this webinar organized as a part of the 2020 CGIAR-CSI Community Meeting, Julian Ramirez, Senior Scientist on Climate Impacts from Bioversity-CIAT Alliance, introduced the Climate Analogues Tool developed in R and show how this tool is being used to generate the Extrapolation Domains for climate adaptation options and help the audience to use the tool in own analysis.
