Abstract
For a country like India with a primarily agrarian economy, limiting warming to 1.5 °C leads to two key questions: what does the global rise of temperature (1.5 °C and 2.0 °C) mean at the regional scale? and; what are the implications of keeping warming at or below 1.5 °C in particular for agriculture and water resources? Regional level analysis can provide a more segregated picture than a global one based on combined metrics. Details of this study show the distribution of predicted values of changes in regional annual rainfall for the 29 States of India obtained using the 78 General Circulation Model (GCM) models Representative Concentration Pathway (RCP 8.5) and 105 GCM models (RCP 4.5).
