In 2012 AgMIP led a Global Gridded Crop Model (GGCM) Intercomparison fast-track project in coordination with the PIK-led Inter-Sectoral Impacts Model Intercomparison Project (ISI-MIP). This fast-track included 7 GGCMs and updated the state of knowledge on climate change vulnerabilities and impacts using modern global high-resolution models driven by climate model output from CMIP5. This fast-track culminated in a PNAS special issue published in early 2014. Initial results indicate the potential of global gridded crop model simulations and the need to further improve understanding of mechanisms, assumptions, and uncertainties of model design and execution; these are best addressed in a coordinated model intercomparison project at continental and global scale. 

In 2013, we launched the AgMIP GRIDded crop modeling inititative (AgGRID) and developed a new set of protocols for the next phase of the GGCMI, which will run for 3 years and include 3 overlapping stages of increasing duration: 
1) Historical simulation and model evaluation 
2) Analysis of model sensitivity to CTWN (carbon, temperature, water, and nitrogen) 
3) Coordinated regional and global climate assessment

The project currently includes results from 14 modeling groups from 11 countries, along with several other major data partners. In this talk we will present results from GGCMI Phase 1, protocols and preliminary results from Phase 2, and describe other projects that AgGRID has undertaken since its founding (including partnerships with other communities such as ISI-MIP and GeoMIP). We will focus especially on historical extreme events.
