Tipping Points. Useful or Disturbing? | Radboud Reflect Lecture by Sibel Eker and Marc Davidson

A global warming of a one and a half degrees and then it's too late. We all know this ecological tipping point or turning point. But scientists have identified more than twenty tipping points, and they all interact. Think for example of water shortages, food security and impacts on the economy. But it's not all doom and gloom: there are also positive tipping points. How are these critical thresholds intertwined? And how should we relate to these tipping points? Do tipping points offer hope and support, or mostly a lot of fear and uncertainty? Listen to systems scientist Sibel Eker and environmental philosopher Marc Davidson explore the tensions and interplay between dozens of tipping points. Tipping Points. Useful or Disturbing? | Lecture and conversation by systems scientist Sibel Eker and environmental philosopher Marc Davidson Monday 16 September 2024 | 20.00 - 21.30 hrs | LUX, Nijmegen Radboud Reflects and Nijmegen School of Management

Drang naar Samenhang | #70 De psychologie van klimaatontkenning

Ondanks vrij veel wetenschappelijk bewijs voor en consensus over klimaatverandering (en de rol van de mens daarbij) zijn er mensen die niet in klimaatverandering geloven. Vaak wordt er gedacht dat iemands politieke voorkeur een belangrijke rol speelt in het wel of niet geloven in klimaatverandering, maar is dat wel zo? In deze aflevering bespreken we recent onderzoek dat de invloed van politieke voorkeur en eerdere overtuigingen van mensen los van elkaar bestudeerd. Daarnaast bespreken we wat - volgens dit recente onderzoek - de rol is van redeneren op het geloof in klimaatverandering. Muziek: Rolf Zwaan Bron Bago, B., Rand, D.G., & Pennycook, G., (2023).

Biobased Construction: Wood

Wood is an important biobased building material, it is one of the oldest and most multifunctional biobased materials. In the past, wood was harvested in an unsustainable way, creating problems regarding its availability. Today, wood producers mostly work in a sustainable way, with the balance between natural growth and harvest restored. This new approach makes wood one of the best solutions for construction by reducing the global warming effects of the building industry and creating healthy, comfortable buildings.

Heatwaves in Tokyo

This report discussed the heatwave shocks happening in Japan and the corresponding solution to the shocks. Heatwaves in Tokyo usually happen in summertime and causes great damage to human health, urban transportation and contributes to power shortage. Citizens especially the aged group suffer a lot from the heat-related diseases and the government faces great challenge to solve the shock. Still, possible solutions exist. First the government need to mitigate global warming by increasing urban green area and cut down carbon emission. Second, citizens need to learn how to deal with the heatwaves. The effects of heatwaves can be mitigated by joint effort of the government and the citizens.

Measure Sustainability: LCA

In this video, Angelica Rota explains the Life Cycle Assessment (LCA) methodology and its specific application to glass products. The LCA is a standardized process that evaluates a product's environmental impact from raw material extraction ("cradle") to final disposal ("grave"). The assessment follows four phases: defining the goal and scope, conducting a life cycle inventory, assessing the environmental impacts, and interpreting the results. For construction products like glass, the life cycle is divided into modules covering production, use, end-of-life, and potential benefits from recycling. The findings of an LCA are often published in an Environmental Product Declaration (EPD), a verified document that communicates transparent environmental data. For flat glass, the manufacturing stage is the most environmentally intensive, contributing the vast majority to its global warming potential due to the high energy required to melt raw materials. Increasing the use of recycled glass cullet is a key strategy for reducing this impact, as it significantly lowers the energy consumption and associated CO2 emissions of the melting process. Understanding LCA is crucial for identifying environmental hotspots and driving more sustainable practices in glass production and use. The video was produced by the Open GLASSroom project.

Drang naar Samenhang | #38 De psychologie van klimaatverandering

Het lijkt wel alsof er elke dag nieuws is over klimaatverandering. Hoe passen we onze kennis hierover aan? Hoe belangrijk is een eigen ervaring met de gevolgen van klimaatverandering hiervoor? En zorgt aangepaste kennis ook voor een verandering is ons gedrag? Aan de hand van recent psychologisch onderzoek proberen we deze vragen te beantwoorden.

Creating a circular healthcare economy: Circular strategies for a sustainable healthcare

Our world is the only planet, as far as we know, which harbors life. The number of humans on our planet has grown tremendously in recent centuries. In 1800 one billion humans occupied our earth; on 15 November 2022, this number reached 8 billion. A result of this growth, the emissions of carbon dioxide (CO2), the primary greenhouse gas emitted by human activities, drastically increased. The increased concentrations of greenhouse gases in our atmosphere foster the long-term increase of our earth’s temperatures, also referred to as global warming. While the earth’s population grew, so did our mass consumption society. After the Second World War humanity witnessed gigantic global economic development with great technological improvements. Computers, laptops, airplanes, tablets and Internet of Things connected humans all over the world. The hunger for plastics and steel grew as all products had to be manufactured in ever-increasing volumes. As the economy developed, our consumption grew apace. The healthcare sector has seen the same increase of consumption. The number of patients grew, and so did the number of single-use medical products. As products become more complex and more different materials were combined., recycling became more difficult. Thus, hospitals transformed into waste factories with ever-growing waste streams. The consumption of (disposable) medical devices takes up scarce raw materials and contributes to the growing CO2 emissions. In this book, Van Straten, Alvino and Horeman present their findings on how to create a sustainable healthcare economy by introducing different circular strategies. In 9 chapters, they present a wide variation of studies as practical cases to show what strategies and actions can be taken in order to implement sustainable strategies for a circular healthcare. This book was written in line with the courses the authors developed at TU Extension School, the open online education edX platform of Delft University of Technology/TU Delft, a leading university in science and technology, recognized for its world-class research. This book is a manual for everyone who follows the online course ‘Circular strategies for a sustainable healthcare’, but certainly also for everyone who wants to discover more about circular strategies and wants to understand the principles and practices of circular economy and urban mining. This book is suitable for students, researchers, policymakers and practitioners in the fields of healthcare sustainability, management, business and economics.
