TL;DR: The Agricultural Model Intercomparison and Improvement Project (AgMIP) as mentioned in this paper is a major international effort linking the climate, crop, and economic modeling communities with cutting-edge information technology to produce improved crop and economic models and the next generation of climate impact projections for the agricultural sector.

TL;DR: The largest maize crop model intercomparison to date, including 23 different models, is presented, suggesting that using an ensemble of models has merit and there was a large uncertainty in the yield response to [CO2 ] among models.

TL;DR: Water use efficiency (WUE) is defined as the amount of carbon assimilated as biomass or grain produced per unit of water used by the crop and there are opportunities to enhance WUE through crop selection and cultural practices to offset the impact of a changing climate.

TL;DR: In this article, two types of impacts on human and ecological systems are examined: (i) impacts of extreme weather and climate events; and (ii) extreme impacts triggered by less-than-extreme weather or climate events (in combination with nonclimatic factors, such as high exposure and/or vulnerability).

TL;DR: There were differences among varieties of corn and soybean for the vegetation indices during the growing season and these differences were a function of growth stage and vegetative index.
