*ITS4.2/CL0.6 session summary:*

Recent evaluations on the states of the Earth system and the integrity of
the Earth system emphasize the alarming decline in Earth’s resilience,
stability, and life support systems. Human activities are driving us beyond
critical planetary boundaries, altering Earth's system processes and
environments on a global scale. Earth’s resilience, stability, and life
support systems are shaped by complex, non-linear interactions between
biophysical processes and human influences. Such interactions encompass the
carbon cycle, atmospheric systems, oceans, large-scale ecosystems, the
cryosphere, and the disruptions caused by socio-economic dynamics. As human
pressures escalate, the risk of breaching key feedbacks in the Earth system
grows, potentially pushing critical components like the ice sheets, the
Atlantic Meridional Overturning Circulation, and biomes such as the Amazon
rainforest beyond tipping points. Crossing these thresholds could trigger
abrupt and often irreversible changes that threaten ecosystems and human
societies. Thus, a comprehensive understanding of the current state of
planetary boundaries on a frequent basis is required. Owing to
technological advancements in Earth observation systems, as well as
advanced AI-based solutions, such objectives can be attained. We invite
contributions from geoscientists, remote sensing specialists, data
scientists, ecologists, climate modelers, and other relevant fields to
explore how we can better measure and assess the planetary boundaries in
the Earth system. We aim to foster interdisciplinary studies on identifying
critical thresholds, understanding feedback mechanisms, and developing
methods to quantify resilience at planetary scales. We are particularly
interested in research utilizing diverse methodological approaches, ranging
from Earth system modeling and remote sensing to data-driven analyses and
conceptual frameworks, focused on stability and health indicators,
nonlinear feedbacks, and the cascading effects of system-wide shifts. This
session seeks to bridge scientific disciplines in an effort to improve our
understanding of Earth’s resilience and stability that can be used to
identify pathways for mitigating risks and promoting transformative,
sustainable change.
