A new generation of an Earth system model now includes a number of land-surface processes directly relevant to analyzing potential impacts of climate change. This
model, HadGEM2-ES, allows us to assess the impacts of climate change, multiple interactions, and feedbacks as the model is run. This paper discusses the results of centuryscale HadGEM2-ES simulations from an impacts perspective– specifically, terrestrial ecosystems and water resources – for four different scenarios following the representative concentration pathways (RCPs), used in the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC, 2013, 2014).
