Extreme climate and weather events, associated disasters, geohazards and emergent risks interact with other stressors, especially growing anthropogenic pressures, and are so becoming increasingly critical in the context of global environmental change. They are a potential major threat to reaching the Sustainable Development Goals (SDGs) and one of the most pressing challenges for future human well-being and safety.
This session explores the linkages between extreme climate and weather events, geohazards, associated disasters, societal dynamics and resilience.
Emphasis is laid on 1) Which impacts are caused by extreme climate events (including risks emerging from compound events) and cascades of impacts on various aspects of ecosystems and societies? 2) Which feedbacks across ecosystems, infrastructures and societies exist? 3) What are key obstacles towards societal resilience and reaching the SDGs, while facing climate extremes? 4) What can we learn from past experiences? 5) What local to global governance arrangements best support equitable and sustainable risk reduction?
Nowadays, to answer this last question, the careful application of social media and crowdsourcing (SMCS) begins to make a contribution, notably in the field of geosciences. SMCS have been integrated into crisis and Disaster Risk Management (DRM) for improved information gathering and collaboration across communities, and for collaboratively coping with critical situations. Numerous governments and EU-funded projects have been exploring the implementation and use of SMCS by developing and adopting new technologies, procedures, and applications. The effectiveness of SMCS on European disaster resilience, however, remains unclear, due to the diversity among disaster risk perception and vulnerability. In general, this second part addresses ways to govern and understand the effectiveness of SMCS for Disaster Risk Management and the related Disaster Resilience is focused.
In this session we welcome empirical with practical applications, theoretical and modelling studies from local to global scale from the fields of natural sciences, social sciences, humanities and related disciplines since the creation of novel effective approaches necessitates a coordinated and coherent effort between them.
Please note that ERL has opened a Focus issue on Earth System Resilience and Tipping Behavior, closely aligned with this session:
Anthropogenic climate change including the increase of unprecedented climate extremes is not a future threat but is happening now. The ability of the atmosphere, hydrosphere or biosphere to adapt to abrupt changes is very limited within a time-frame meaningful to our present social structures. Consequently, determining the resilience of these earth system components to anthropogenic forcing has become a global concern. The resilience of the system, that is its ability to resist these climate disturbances and to recover from the perturbed state, will be a decaying function of the disturbance intensity. Tipping point dynamics can be used to determine system transition conditions at which the perturbed state is no longer decaying but growing and tipping into a new and potentially stable functional branch of the possible outcomes. In the face of catastrophic changes that might be coming, it is vitally important for policy makers and others to know the conditions at which a tipping point could be reached and exceeded. The earth system is highly nonlinear with many positive and negative feedback interactions so that the tipping behavior is complicated. The complexity raises many open research questions: (1) how to determine the tipping elements? (2) what are the early-warning signals for system transitions? (3) what are the potential domino effects for tipping-cascades of abrupt transitions, and (4) does warming climate increase the risk of triggering tipping points?
