Paper Title
Language & Climate Change Discourse: The IPCC Special Report on Global Warming of 1.5°C

Abstract
This research reviews how methodologies in Applied Linguistics have been applied to major aspects of climate change and sustainability discourse. Subsequently, a selection of those methods are applied to the most recent IPCC ‘Special Report’ on Global Warming of 1.5° C. Through comparison with existing data on the AR-Series Reports, a number of insights into the unique nature of the Special Report are achieved. Moreover, the Register Analysis framework, pervasive in wider Applied Linguistics, is shown to be efficacious, and this paper thereby constitutes a foundation upon which the increasingly proliferate reports of both the IPCC and also other key sustainability texts can be approached. Keywords - Applied Linguistics; Climate Change Discourse; IPCC; Register Analysis
