"This assessment identifies and summarizes the latest peer-reviewed research related to the impact of climate change on India, drawing on both the literature summarized in the latest Intergovernmental Panel on Climate Change (IPCC) assessment reports and on other peer-reviewed research literature and relevant reporting. It includes such impact as sea level rise, water availability, agricultural shifts, ecological disruptions and species extinctions, infrastructure at risk from extreme weather events (severity and frequency), and disease patterns. This paper addresses the extent to which regions within India are vulnerable to climate change impact. The targeted time frame is to 2030, although various studies referenced in this report have diverse time frames. The research does not draw inferences about the potential for internal or interstate conflict arising out of changes, e.g., in water supply or in likely migration from Bangladesh; such analyses will be conducted in the subsequent efforts described above. This assessment also identifies (Annex B) deficiencies in climate change data that would enhance the IC [Intelligence Community] understanding of potential impact on India and other countries/regions."
