TL;DR: Investigating the impacts of temperature on yields of the four crops by compiling extensive published results from four analytical methods consistently showed negative temperature impacts on crop yield at the global scale, generally underpinned by similar impacts at country and site scales.

TL;DR: Sensitivity analysis indicates the necessity to improve the accuracy in predicting both biomass and harvest index in response to increasing [CO2 ] and temperature, and suggests a use of an ensemble of crop models can reduce the uncertainties.

TL;DR: This paper showed that grid-based and point-based simulations and statistical regressions, without deliberate adaptation or CO 2 fertilization effects, produce similar estimates of temperature impact on wheat yields at global and national scales.

TL;DR: Interestingly, heat stress between heading and maturity was more severe in the generally cooler northern wheat-growing regions than the generally warmer southern regions of China, because of the delayed time of heading with low temperatures during the earlier growing season and the exposure of the post-heading phase into the warmer part of the year.

TL;DR: In this paper, 15 wheat growth models of a larger MME were improved through re-parameterization and/or incorporating or modifying heat stress effects on phenology, leaf growth and senescence, biomass growth, and grain number and size using detailed field experimental data from the USDA Hot Serial Cereal experiment (calibration data set).
