Human-Earth System Interactions

The Aspen Global Change Institute hosted a workshop to bring together researchers working on 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. Workshop themes included identification of critical feedbacks between human and earth system processes across scales, the relative importance of human-earth system feedbacks in the uncertainty of future outcomes; implications of human-earth system feedbacks on long-term trend modeling in the next generation CMIP and scenario design.

Participants collaborated virtually through facilitated dialogues, individual surveys, a poster session, a live public lecture, and opportunities for informal networking. Workshop participants also initiated a synthesis paper to highlight new insights, key challenges, and promising research directions in linking human and Earth system models for global change analysis.

“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.
