A study by Dartmouth researchers lays out a scientific framework for holding individual fossil fuel companies liable for the costs of climate change by tracing specific damages back to their emissions. The researchers use the tool to provide the first causal estimate of economic losses due to extreme heat driven by emissions. They report that carbon dioxide and methane output from just 111 companies cost the world economy $28 trillion from 1991 to 2020, with the five top-emitting firms linked to $9 trillion of those losses.
Against the backdrop of accelerating global climate change and urbanization processes, urban transportation systems are confronting increasingly complex multi-hazard risks. Spatiotemporal big data, characterized by its high precision and information density, has demonstrated growing significance in transportation system resilience studies. Nevertheless, the current comprehension of the evolutionary trajectory of spatiotemporal big data applications in this domain remains fragmented. In this context, our study conducts a systematic review of global research, elucidating the practical implementations of spatiotemporal big data in transportation system resilience studies. The investigation reveals that multi-source big data with high spatiotemporal resolution has not only catalyzed methodological innovations in resilience assessment but has also potential to facilitate a paradigm shift in the field - transitioning from macro-scale to micro-scale analyses, from static evaluations to dynamic monitoring approaches, and from post-disaster emphasis to comprehensive lifecycle investigations. Journal of Geo-Information Science has published the study's results.
