The Earth's climate system seems to have shifted abruptly between colder and warmer modes in the past. Do we risk the same today from anthropogenic climate change? Frankly, climate models cannot answer that question yet. But a result in the journal Chaos by Gisela D. Charó, Mickaël D. Chekroun, Denisse Sciamarella and Michael Ghil suggests a way to resolve the matter. Analyzing a model that combines the two leading theories for climate change with algebraic topology tools, the authors show that the climate system indeed progresses through abrupt transitions, also known as tipping points. These tools are applicable to reduced climate models and they well might help assess whether the Earth's climate system on a whole is about to tip due to global warming. The work is part of the TiPES project, a European science collaboration on tipping points in the Earth system.

Accurate and near real-time data on the course and evolution of the COVID-19 pandemic have been instrumental in informing public health mitigation strategies and policy worldwide. Although many aspects of the pandemic have been tracked across numerous types of data, including rates of infection, hospitalizations and deaths, Christina Pagel and Christian Yates argue in a Perspective that the inherent biases and pitfalls in interpretation in each data source need to be recognized and accounted for. “Because choosing the right mitigation policies relies on an accurate assessment of the current state of the local epidemic, the potential ramifications of misinterpreting data are serious,” write the authors. Pagel and Yates provide an overview of the ways in which COVID-19 is currently being tracked worldwide, like through case rates, for example, and highlight the sources of potential bias inherent within related data. What’s more, the authors discuss the data not currently being reliably captured, particularly incidences of Long Covid and breakthrough cases among vaccinated individuals. According to Pagel and Yates, using all available data to quantify the pandemic is crucial to address it, and relying too much on a single data source or a limited selection of aggregated data risks misunderstanding the state of the epidemic.
Financial inclusion is key to improving economic and social welfare, reducing inequality, and promoting economic growth. Globally, 1.7 billion people have limited access to financial services, especially in the developing world. As governments and NGOs work to strengthen financial resilience, digital technology has become a crucial component. New research from a University of Illinois specialist and a team of international collaborators investigates the intersection of financial and digital literacy and its relationship to resilience-building financial behaviors.
