The study investigates the repercussions of climate change on food-grain yield in India. An empirical investigation of the change in the impact over a decade of physical components of Greenhouse gases (GHGs) i.e. rainfall and temperature along with carbon emissions on the food grain yield has been done. The cross-sectional data of all the Indian states and UT’s have been taken to perform multiple linear regression, and it has been found the carbon emission is insignificant in 2011–12. However, over a span of 10 years it has been observed to be significantly impacting the food grain production in India. Moreover, the coefficient of rainfall has reduced from 2.69 to 2.4 signifies adverse impact on food grain yield. The study concludes that climate change will impact food-grain physiology and irrigation, affecting agricultural production and sustainability. Thus provides a robust foundation for policymakers, researchers, and stakeholders to formulate adaptive measures that can enhance the resilience of Indian agriculture in the face of ongoing climate changes.
