Globalization is a fascinating spectacle that can be understood as global systems of competition and connectivity. These man-made systems provide transport, communication, governance, and entertainment on a global scale. International crime networks are outgrowths of the same systems. Topics include national identity, language diversity, the global labor market, popular culture, sports and climate change.

However, an increase in integration has not brought increased equality. Globalization creates winners and losers among countries and global corporations, making competition the beating heart of the globalization process.

The globalization process exemplifies connectivity. Globalization is unimaginable without the unprecedented electronic networks that project dominant cultural products into every society on earth.

Learn how to identify and analyze global systems and better understand how the world works.

In public discussions, climate change is a highly controversial topic. However, in the scientific community, there is little controversy with 97% of climate scientists concluding humans are causing global warming.

• Why the gap between the public and scientists?
• What are the psychological and social drivers of the rejection of the scientific consensus?
• How has climate denial influenced public perceptions and attitudes towards climate change?

This course examines the science of climate science denial.

We will look at the most common climate myths from “global warming stopped in 1998” to “global warming is caused by the sun” to “climate impacts are nothing to worry about.”

We’ll find out what lessons are to be learnt from past climate change as well as better understand how climate models predict future climate impacts. You’ll learn both the science of climate change and the techniques used to distort the science.

With every myth we debunk, you’ll learn the critical thinking needed to identify the fallacies associated with the myth. Finally, armed with all this knowledge, you’ll learn the psychology of misinformation. This will equip you to effectively respond to climate misinformation and debunk myths.

This isn’t just a climate MOOC; it’s a MOOC about how people think about climate change.

In this interdisciplinary course you will learn about the water-related dimensions of environmentally sustainable urbanism. The course features Vancouver, one of the world's leading cities for green design.

Introduction to Environmental Science, ENVX, was first offered in early 2015.

Environmental science is the study of patterns and processes in the natural world and their modification by human activity.  To understand current environmental problems, we need to consider physical, biological and chemical processes that are often the basis of those problems. This course will give you the skills necessary to address the environmental issues we are facing today by examining scientific principles and the application of those principles to natural systems.  This course will survey some of the many environmental science topics at an introductory level, ultimately considering the sustainability of human activities on the planet.

Environmental impacts on Earth come from the number of people and the amount and types of resources that they use. By applying scientific principles and considering real-world examples, we will examine:

• The field of environmental science and how to think like an environmental scientist
• The human population and the ways in which changes in the population affect the environment
• Agriculture, soils and the environmental implications of eating meat, vegetables, local, organic, sustainable, industrial and other types of food
• Non-renewable fossil fuels with a focus on coal, petroleum and natural gas and the benefits and consequences of using each
• Renewable fuels such as wind and solar and identify that even renewable “green” energy sources have impacts as well as benefits
• Biodiversity and global change, which are the integrating units of environmental science

Education method
The course will utilize video lectures, interviews with experts, readings, discussions, multiple choice and prompted discussions and one graded quiz per week. There will also be several optional live office hours on Google Hangouts.

Completion of self-assessments, contributions to discussion and quiz scores will determine the final grade.

Sustainability, defined by Rice’s Energy and Environment Institute (EEi), is energy security, affordability, and environmental responsibility as the three required foundational pillars.    

We will explore and understand the fundamental principles of energy sustainability from the perspective of the techno/economic framework and maturity of the market in the geography of interest. Global impact and the effects of global commerce will drive investment and the hierarchy of the three fundamentals. With an emphasis on the oil and gas sector, petrochemicals, and power industry, thought leaders will discuss these principles with participants in the context of real-world industry examples and share their personal insights on best practices and future trends.

The four-week course will examine three fundamentals of energy sustainability and their application in today’s dynamic industry landscape in oil and gas (upstream, midstream, downstream), petrochemicals (upstream and downstream), power and energy trading:

1. Available and secure supply of energy. A portfolio of options and interconnections of supply and demand for long-term access and systems analysis of best available options.
2. Affordable and competitive cost of energy. An analysis of economic competitiveness and investment options for not only generation but a systems analysis of total cost impact.
3. Environmental responsibility in the production and consumption of energy. An analysis of technical options and the optimizing of local and international policy and regulations.

Through guest presentations and interviews with business executives and thought leaders, case studies, cutting-edge research and interactive learning experiences, participants will build the relevant knowledge and capabilities to effectively deliver consulting and support services effectively to specific clients and enterprises in the market. Assessment will include methods such as quizzes, written reflections, individual/team projects, etc.

This water sustainability course (PH242x) from Tufts University focuses on the engineering and public health components needed to achieve the conservation of safe water locally and globally. Together, we will explore how to create sustainable interventions geared towards improving population health.

This course provides an interdisciplinary framework for understanding the place of water in health policy and engineering by delving into the complex social, economic, political and scientific factors that influence how we approach these critical health and water related challenges. 

We identify threats to our water supply, including climate change, urbanization, agriculture and emerging contaminants. We lead a water sampling field trip and analyze the results in order to understand how water quality is assessed and regulated. We learn how to conduct a “Risk Assessment” as it relates to human and environmental health. The class will debate about issues such as water privatization, social and environmental justice and hydrofracturing. We’ll learn about point of use interventions for local interventions and take a field trip to the massive Massachusetts Water Resources Authority to see firsthand how large scale interventions are built and managed. Lastly, we will learn about various anthological determinants that drive the sustainability of interventions, review strategies for water management in developing and developed countries, and discuss the opportunities and challenges with implementing these solutions.

In addition to lectures hosted by Tufts Professors Dr. David M. Gute and Dr. Jeffrey K. Griffiths, the course features field trips, and guest lecturers comprised of renowned water professionals, entrepreneurs and scientists from the fields of public health, engineering, environmental science and health policy.

We hope that your ability to conceptualize and address water-related issues will advance as a result of the lecture content, in class demonstrations and global dialogues. To achieve this goal, we strongly encourage active participation and discussion with the professors, students and water professionals from across the globe.

We live on the surface of a dynamic and yet paradoxically stable planet that experiences a remarkable range of energetic phenomena, from waves and currents in the ocean to wind and thunderstorms in the atmosphere. This course traces how the remarkable concept called energy is the natural way of describing, understanding and unifying these diverse phenomena. The course traces the cascade of energy from sunlight to its final destination in a thermal form, considering differential surface heating, the role of convection and buoyancy and the formation of the Earth’s circulation system, and the links to the ocean circulation system. We consider the curvature and rotation of the Earth as key constraints on a system driven by sunlight and energy transformations.

How much time will the course take?

Obviously the answer will depend on your background and motivation to master the course material. Each week will consist of 5 or 6 segments that will each take 5 to 10 minutes to watch or listen to once. There will be some exploratory questions for each lesson and a confirmation quiz for each week. There will be one exploratory activity for each week. The average commitment will be 2-3 hours per week with perhaps 20 hours required for the whole course.

What background does the course assume?

We’ll ask you to pull out a calculator from time to time (but not all the time!) simply as this will help you really master the key ideas. The key thing is to have a curiosity and interest in what makes our planet tick!

What kind of learning activities will the course involve?

The activities are designed to use basic household objects, and our own senses, to engage with observations of the world, and to think about what these mean and lead to. We’ll get you to sense how cold or warm different objects get when left in the sun, and to observe how energy explains things we see and hear.

What difference will the course make to my life?

The course has the conviction that it is hard to care for or value things that we don’t appreciate or have never considered. Although harsh in certain places and times, the Earth’s surface is remarkably habitable. Many forms of life can make their way in many kinds of terrain and climate. What produces these conditions? How are they maintained? We will seek to answer those questions in rudimentary form at least.

What conversations will the course help to perform?

Courses often imagine a context in which the course material is discussed, and this one is no different. It imagines a setting with family or friends where you might have just learned of a news event involving a storm like a hurricane or thunderstorm, or where a community might have experienced a flood or a drought, or merely unusual weather. You might have heard of El Nino or climate change in the news. This course will give you a background to better engage in a conversation about these great matters, and offer a better sense of the complexity, challenge and wonder connected to living on the surface of such an energetic planet.

This interdisciplinary course explores the complex interactions between poverty, rural livelihoods, and forest resources in developing countries.  We will consider some of the dynamics that occur when impoverished people use forests in their daily lives. We will talk about the role of forests for medicines and wild foods, as sources of fuelwood and charcoal for energy, and other pressing topics that confront sustainable forest management such as the impacts of human health and diseases on forests. The course consists of modules on forests and livelihoods in developing countries, agroforestry, human health in forested environments, protected areas and their sustainability, small and medium forest enterprises (SMFEs), and  community forestry. Three cross-cutting themes (gender, tenure and forest rights, and climate change) will span all of the modules.

This course will engage you in developing a deeper understanding of the fundamental importance of forest resources in the lives and livelihoods of people in developing countries. Participants from tropical and developing countries may have lived much of what we will talk about in this course, and your experiences will deepen our understanding of the course material. Participants not from a developing country will gain a much better appreciation for the multitude of ways that people in developing countries use forest resources. Weekly videos will be complemented by readings, quizzes, and links to online resources to help you explore current scholarship in this domain. A discussion forum will enable you to delve more deeply into these issues with other participants and the course staff. The themes covered in this MOOC are important to anyone working in international forestry.

Water is essential for life on Earth and of crucial importance for society. Water also plays a major role in affecting climate. Its natural cycle, from ocean to atmosphere by evaporation, then by precipitation back to land returning via rivers and aquifers to the oceans, has a decisive impact on regional and global climate patterns.

For students of engineering, climate science and environmental studies, this course offers a first introduction to the physics of water systems and their role in climate. In addition, we show you the state-of-the-art engineering interventions that can be applied to water systems. These can improve coastal safety and increase the availability of water supplies worldwide.

The course welcomes students from all over the globe, so we actively encourage discussion of water and climate issues you may experience in your location, now and in the coming decades.

After taking this course, you will be able to:

• Understand the different processes at play in the global water cycle.
• Identify and describe the flows of water and sand in different riverine, coastal and ocean systems.
• Identify mechanisms of climate change and explain the interplay between climate change, sea level, clouds, rainfall and future weather.
• Explain why, when and which engineering interventions are needed in rivers, coastal and urban environments.
• Explain why water for food and water for cities are the main challenges in water management and propose solutions.
• Explain and confront the challenges in better understanding and adapting to the impact of climate change on water over the coming 50 years.

The course consists of knowledge clips, movies, exercises, and exam assignments. There are opportunities to discuss course materials with your fellow students and the Course Team through our online forum. We also provide interactive feedback video sessions in which the lecturers discuss issues raised by students.

Delft University of Technology (TU Delft) has a unique reputation when it comes to water and climate, with faculty experts in the fields of climate research, water management and hydraulic engineering. The course introduces you to many aspects of water and climate: from the micro scale of raindrops to the macro scale of oceans, and from understanding the physics of the different water systems to practical engineering solutions that may help societies adapt to the present and future impacts of climate change on water.

Together with the courses "Drinking water treatment" and "Urban Sewage Treatment" this course forms the Water XSeries, from the Faculty of Civil Engineering and Geosciences at TU Delft.
