The global impacts of climate change under 1.5ºC, 2ºC, 3ºC and 4ºC pathways (AVOID2)

This research, by the AVOID2 consortium, was commissioned by the Committee on Climate Change to inform ‘the scientific and international context for the fifth carbon budget’ report published in October 2015.

The research describes an assessment of the global-scale impacts of climate change under three different potential temperature pathways through the 21st Century. These pathways reach peaks of 2ºC, 3ºC and 4ºC above pre-industrial values by 2100.

Impacts are represented by indicators covering the water resources, river flooding, coastal flooding, agricultural, environmental and health (heat) sectors, and population and economic growth are assumed to develop along the same ‘middle of the road’ trajectory under all three climate futures.
