What do 4 C and 6 C worlds look like in comparison to 2 C & 1.5 C? and What are the consequences of different adaptation choices? The core of our HELIX work has looked at the global scale, but there is an additional focus on three key regions of Europe, northern sub-Saharan Africa, and the Indian sub-continent. Ashvin Gossain and Sandhya Rao of the Indian Institute of Technology Delhi applied the HELIX approach to the Ganga River Basin. Please see their summary report launched at the Final Delhi Stakeholder Workshop ‘High End Climate Change for Specific Warming Levels and their Implications in the Ganga River Basin’, also available in Hindi.
