High temperatures are associated with reduced crop yields and predictions for future warming have raised concerns regarding future productivity and food security. However, the extent to which adaptation can mitigate such heat-related losses remains unclear. Here we empirically demonstrate how maize is locally adapted to hot temperatures across US counties.

Recent studies concerning the possible relationship between climate trends and the risks of violent conflict have yielded contradictory results, partly because of choices of conflict measures and modeling design. In this study, we examine climate–conflict relationships using a geographically disaggregated approach. We consider the effects of climate change to be both local and national in character, and we use a conflict database that contains 16,359 individual geolocated violent events for East Africa from 1990 to 2009.

Phytolith occluded carbon (PhytOC) which is stable in the soil environment is considered to be an important
fraction of soil organic carbon and substantially contributes to the terrestrial carbon sequestration for long periods (millennia). Phytoliths are silica bodies produced by plants as a result of biomineralization process. During this process, occlusion of carbon also takes place within the phytoliths. Some of the major agricultural crops like barley, maize, rice, sorghum, sugarcane and wheat are known to be prolific producers of phytolith and PhytOC. In India, an estimate
