Electromagnetics Volume 1 by Steven W. Ellingson is a 225-page, peer-reviewed open educational resource intended for electrical engineering students in the third year of a bachelor of science degree program. It is intended as a primary textbook for a one-semester first course in undergraduate engineering electromagnetics. The book employs the “transmission lines first” approach in which transmission lines are introduced using a lumped-element equivalent circuit model for a differential length of transmission line, leading to one-dimensional wage equations for voltage and current.

Where is humanity going? How realistic is a future of fusion and space colonies? What constraints are imposed by physics, by resource availability, and by human psychology? Are default expectations grounded in reality?

This textbook, written for a general-education audience, aims to address these questions without either the hype or the indifference typical of many books. The message throughout is that humanity faces a broad sweep of foundational problems as we inevitably transition away from fossil fuels and confront planetary limits in a host of unprecedented ways—a shift whose scale and probable rapidity offers little historical guidance.

Salvaging a decent future requires keen awareness, quantitative assessment, deliberate preventive action, and—above all—recognition that prevailing assumptions about human identity and destiny have been cruelly misshapen by the profoundly unsustainable trajectory of the last 150 years. The goal is to shake off unfounded and unexamined expectations, while elucidating the relevant physics and encouraging greater facility in quantitative reasoning.

After addressing limits to growth, population dynamics, uncooperative space environments, and the current fossil underpinnings of modern civilization, various sources of alternative energy are considered in detail— assessing how they stack up against each other, and which show the greatest potential. Following this is an exploration of systemic human impediments to effective and timely responses, capped by guidelines for individual adaptations resulting in reduced energy and material demands on the planet’s groaning capacity. Appendices provide refreshers on math and chemistry, as well as supplementary material of potential interest relating to cosmology, electric transportation, and an evolutionary perspective on humanity’s place in nature.

This first-year undergraduate open textbook covers the most salient environmental issues from both biological and social science perspectives.

This textbook is written for an audience of introductory college students in a non-science degree program. It is intended to provide a detailed comprehensive knowledge of Planet Earth, including basic aspects of physics, chemistry, geology and biology. As a major scientific overview of the entirety of Planet Earth, the intention is to only present key concepts that will enhance, enrich, and engage the readers interest in Earth Sciences. It is intended to make any reader, such as yourself, at least a little more knowledgeable of the amazing place that we all live within. Hosted as a WikiBook.

Essentials of Geographic Information Systems integrates key concepts behind the technology with practical concerns and real-world applications. Recognizing that many potential GIS users are nonspecialists or may only need a few maps, this book is designed to be accessible, pragmatic, and concise. Essentials of Geographic Information Systems also illustrates how GIS is used to ask questions, inform choices, and guide policy. From the melting of the polar ice caps to privacy issues associated with mapping, this book provides a gentle, yet substantive, introduction to the use and application of digital maps, mapping, and GIS.

The year is 2050 and your once-idyllic beachfront vacation home is now flooded up to the second story. The crab your family has enjoyed every Christmas for as long as you can remember has now become an endangered species. The oceans have changed. In Earth 540, Oceanography for Educators, we explore the mechanisms that lead to sea level rise and ocean acidification. We strive to understand how natural processes such as ocean currents, the gulf-stream, tides, plate tectonics, and the Coriolis Effect, affect our oceans and ocean basins. We then predict how man-made issues such as climate change and overfishing will affect our beloved waters and our livelihoods. Want to see into the future? Then this course is for you!

Short Description:
When it comes to climate change, studies have shown that youth are more likely to report mental health concerns in comparison to older generations. Emerging research underlines that youth who enroll in environmental classes consistently report increased levels of stress as a result of their heightened awareness of planetary health challenges. This toolkit is designed for use by educators to empower students to think critically about the structural and socio-political inequities that affect them while centering climate change and mental health through embedded reflective exercises. Questions that explore eco-anxiety, ecological paralysis and ecological grief are included in this toolkit. Students are encouraged to answer questions according to the emotions that they resonate most with and want to explore further. Additionally, students are encouraged to examine the relationship between anthropogenic activity, mental health and their values, emotions and behaviours. The PDF version of this toolkit is available for download here: https://pressbooks.bccampus.ca/eccmh/wp-content/uploads/sites/1644/2022/04/2April2022_TOOLKIT_Exploring-Mental-Health-and-Climate-Change_compressed-1.pdf.

Long Description:
When it comes to climate change, studies have shown that youth are more likely to report mental health concerns in comparison to older generations. Emerging research underlines that youth who enroll in environmental classes consistently report increased levels of stress as a result of their heightened awareness of planetary health challenges. Unfortunately, though there are increasing numbers of people who will be affected by the mental health impacts of climate change, factors such as psychological distance and denial influence the way individuals form their beliefs and take action on this issue. In response to the need for more innovative teaching tools in undergraduate curricula, as well as the eagerness of youth to learn about planetary health, a 25-minute film and accompanying toolkit were created focusing on the relationship between mental health and climate change. In addition to climate change experts, the film features UBC students who were previously enrolled in the UBC nursing elective course NURS 290: Health Impacts of Climate Change. The educational toolkit uses knowledge mobilization and health promotion strategies based on the Transtheoretical Model of Change. The film and toolkit are tools designed for use by educators to empower students to think critically about the structural and socio-political inequities that affect them while centering climate change and mental health through embedded reflective exercises. By featuring the voices of students, this project is not only relevant and impactful but also addresses the diverse learning needs of students. The PDF version of this toolkit is available for download here.

In this book I've attempted an innovation in the order of topics for freshman E&M, the goal being to follow the logical sequence while also providing plenty of opportunities for relating abstract ideas to hands-on experience. The typical sequence starts by slogging through Coulomb's law, the electric field, and Gauss's law, none of which are well suited to practical exploration in the laboratory. In this book, each of the first 5 chapters is short and includes a laboratory exercise that can be completed in about an hour and a half. The approach I've taken is to introduce the electric and magnetic field on an equal footing (which is in fact the way the subject was developed historically). As empirically motivated postulates, we take some primitive ideas about relativity along with the expressions for the energy and momentum density of the fields.

Another goal is to introduce the laws of physics in their natural, local form, i.e., Maxwell's equations in differential rather than integral form, without getting bogged down in an extensive development of the toolbox of vector calculus that would be more appropriate in an honors text like Purcell. Much of the necessary apparatus of div, grad, and curl is developed first in visual or qualitative form.

This open online course introduces participants to the financial risks and impacts associated with climate change.

Long Description:
This four-week course introduces participants to the financial risks and impacts associated with climate change. Participants will explore a range of risk pathways that link climate and economic systems, including:

• physical risks related to direct exposure to climate hazards in the value chain; • transition risks arising from abrupt transitions to a low-carbon economy; • systemic risks transmitted throughout the economy; • extreme risks arising from the complex dynamic nature of climate-economy systems.

Topics will be explored through the use of case study examples, group-based analysis and problem solving. The learning is supported by readings, videos and live, interactive online sessions. Participants are encouraged to share their own knowledge and expertise in group-based discussion forums. Upon completion of the course, participants will have a foundational understanding of the relationship between climate change and the economy. Participants will develop their ability to identify climate-related financial risks within their own organizations—critical groundwork for effective planning and decision-making for mitigation and adaptation.

As an introductory course, this course is suited to those with limited previous experience in climate-related finance or economics. However, a basic understanding of climate science is presumed.

This course is part of the Adaptation Learning Network led by the Resilience by Design Lab at Royal Roads University. The project is supported by the Climate Action Secretariat of the BC Ministry of Environment & Climate Change Strategy and Natural Resources Canada through its Building Regional Adaptation Capacity and Expertise (BRACE) program. The BRACE program works with Canadian provinces to support training activities that help build skills and expertise on climate adaptation and resilience.

Drawing upon the food security literature and current events in the media, this survey course will encourage learners to build a new understanding of food security, water shortages in agricultural production, and climate change challenges in agriculture. We will introduce policy tools and case studies illustrating the effects that climate change has on agriculture which will be useful and applicable to individual cross-disciplinary learning.

Long Description:
Food security is one of the most pressing dilemmas of our time. Around the globe, approximately 2 billion people experience some form of food deprivation each day. One in ten people suffer from some form of food insecurity in Canada. This has led scholars to question why food insecurity exists in an ostensibly food secure country. The literature on food security and climate change has also grown exponentially over the past several decades in large part as a response to world events such as the Green Revolution and other forms of industrial agricultural development since the 1970s. Despite the advances in research and technology, we still possess inadequate knowledge of the dynamics causing the onset of food insecurity, and significant disagreement persists among scholars concerning the best way to ameliorate food insecurity.

Drawing upon the food security literature and current events in the media, this survey course will encourage learners to build a new understanding of food security, water shortages in agricultural production, and climate change challenges in agriculture. We will introduce policy tools and case studies illustrating the effects that climate change has on agriculture which will be useful and applicable to individual cross-disciplinary learning.
