Human-Earth System Interactions

The human impact on the Earth’s system has been coined anthropogenic climate change. The feedbacks between climate and society have been examined in order to understand how humans can change and improve their behavior to have a better impact on the climate. Greenhouse gas emissions are just one example of human behavior with harmful environmental impacts, but cumulative land use change (LUC) emissions are greater by far. Socio-politico-technical processes will determine policy implementations, climate projections, and feedbacks between climate and society. Solutions to climate change rely on these processes to understand how humans interact within the Earth System. Here we feature a series of talks given at the Aspen Global Change Institute addressing a range of strategies to better understand the interactions and feedbacks between human and earth systems through improved linkages and coupled modeling of human and earth systems.

Complexity and Uncertainty of Human Feedbacks to Climate Change

Speaker: Brian Beckage, University of Vermont

Date aired: 19 July 2021

Land Use Climate Feedbacks- Reconciling Mitigation and Adaptation

Speaker: Julia Pongratz, University of Munich

Date aired: 19 July 2021

Case Study 1 – Climate System: Integrating human and modeling uncertainty, impacts and extreme projections, missing processes, and ensemble limitations

Speaker: Claudia Tebaldi, CGD/NCAR

Date aired: 20 July 2021

Case Study 2 – Mitigation: Afforestation and carbon dioxide removal

“Halting Climate Change: Why Zero Emissions Is Only the Beginning”

Speaker: Joeri Rogelj, Imperial College London

Date aired: 20 July 2021

About: The 2015 U.N. Paris Agreement has set a goal of keeping global warming well below 2°C, and preferably to 1.5°C. In this lecture, Dr. Joeri Rogelj of Imperial College London looka at what that means for the amount of carbon dioxide that can still be emitted, the emissions pathways we need to follow, and why reaching net-zero emissions is only the beginning of a much longer journey.

Role of Human-Earth System Interactions in Scenario and Model Development: A CMIP-Focused Discussion

Speaker:Jean-François, National Center for Atmospheric Research

Date aired: 21 July 2021

Representation of Land Use/Cover Change and Land Management in Scenario-Based Modeling
