Using an Integrated Human-Earth System Model to Explore the Multisectoral Impacts of Global Change

Speaker: Neal Graham, Pacific Northwest National Laboratory.

Abstract: Scientists leverage Global Circulation Models (GCMs) and Earth System Models (ESMs) to study how atmospheric and oceanic changes may evolve in time due to our complex and changing climate. For example, these models allow us to understand how precipitation and temperature may change in a world with radiative forcing of 2.6 W/m2 at the end of the century However, what these models often miss are the influences brought upon by humans, and the feedbacks brought upon by decision-making which alter the supply and demand of energy, water, and land around the world. During this talk, I will discuss the Global Change Analysis Model (GCAM), the types of research questions that we seek to answer using GCAM, and how this work leads to tangible changes around the world. Additionally, I will discuss how the complexities of global and regional energy-water-land nexus plays a role in how we think about water supply and demand in the future. Finally, I will highlight the how future agricultural trade, under varying degrees of globalization, future energy transitions, and socioeconomic growth may drive multisectoral feedbacks which change energy, water, and land availability around the world, for better or worse.
