Wil je kunnen meepraten over het onderwerp, begrijpen wat ‘klimaat’ eigenlijk is, waar we wel of niet bang voor moeten zijn, kun je je opgeven. Dit is een open online cursus, volledig gratis, tenzij je een certificaat wilt (ongeveer 30 euro). Geen specifieke voorkennis nodig.

De content van de cursus:
Climate Literacy tackles the scientific and socio-political dimensions of climate change. This course introduces the basics of the climate system, models and predictions, human and natural impacts, mitigative and adaptive responses, and the evolution of climate policy.
Climate Literacy is delivered in ten Modules. The first half of the course deals mainly with climate change science and models, while the second half of the course speaks to climate change impacts, response options, and polices. The Modules are as follows:
1. Climate in the public sphere
Climate change is a pervasive and challenging phenomenon that can be viewed through a multitude of lenses. A scientific lens, for instance, reveals altered ecosystems and climatic tipping points while the lens of ethics raises the question of the right to develop and influence the well-being of others while doing so. This module will introduce you to a few of the core concepts that you will need to delve deeper into the science and policy of climate change. We will explore the broad findings offered by the scientific community with regard to our influence on the climate system, the policy tools that we have developed to respond to this challenge, and the core of the climate change debate in scientific, political, and lay communities.
2. Introduction to the climate system
In this first module of the science section of the course, we’ll look at the big picture of Earth’s climate system. What are the parts? What are some of the major interactions among the parts? We’ll spend some time learning about the energy-related units we’ll use in this course, some basics of systems dynamics, which is one of the overarching frameworks in this course, and then we’ll have a look at data showing how Earth’s climate has changed over time.
3. Earth’s energy budget
This module covers the basics of climatology at the planetary scale. We will trace the path of energy coming in from the Sun and leaving the planet as thermal radiation (or infrared), and explore the various factors affecting these flows: greenhouse gases, aerosols, surface albedo, and clouds. We will investigate how humans influence these climate controls, and compare anthropogenic factors to natural factors such as variation in solar energy and volcanic eruptions.
4. The carbon cycle
Our planet breathes; its biosphere on land and in the oceans inhales and exhales oxygen and carbon dioxide every second. Even water and rocks exchange carbon dioxide with the atmosphere. Humans, particularly through deforestation and fossil fuel use, have a significant impact on the planetary carbon cycle. This module explores the natural carbon cycle, the perturbations in carbon stocks and flows from human activities, and the climate system’s response to human perturbations.
5. Climate models
Climate models are crucial tools to help people understand the complexities and dynamic interactions within Earth’s climate system. Models are built on our understanding of basic physics and Earth processes, and are grounded in observations and measurements of the world around us. In this module, we’ll explore different types of climate models, consider some of the choices you’d need to make as a climate modeler, and have a look at some climate model output compared to observations. Since we only have one planet, and can only run one global climate experiment in the real world, models are our only tools to help us peer into the future and ask “what if…” questions. The range of probable outcomes from possible future scenarios helps us make decisions about mitigation and adaptation.
6. Future climate
Now that we have a clearer sense of the principles, components and assumptions of climate models, we’ll look more closely at their results. Given hypothetical future pathways, including possibilities for our own future actions, like carbon emissions, what range of temperature increases can we expect? How will future changes affect the climatic factors that are most relevant to humans and ecosystems: precipitation, circulation patterns, extreme events, melting of snow and ice, etc? These global projections give us estimates of what we can expect if we embark on various emission and development paths, and offer a broad view for decision-making. The least well-known aspect of these projections is what choices we, the human community, will make in the future.
7. Climate change impacts
As we have seen, the emission of vast quantities of greenhouse gases by humans fundamentally influences the global climatic system. The chain reaction does not end here, however. Rising temperatures and sea levels, changing precipitation patterns, and ocean acidification, for instance, trigger dramatic shifts in the way that human and natural systems function.
This module forms the transition between the science of climate change, which we have explored in Modules 2-6, and the more human-oriented Modules 7-10.
8. Climate change mitigation: dealing with the causes
Now that we understand the central causes of anthropogenic climate change, and the impacts that we can expect to (and already) experience, the next step is to explore the response options that are available to us. The most commonly-discussed response to climate change is mitigation: tackling the causes of climate change by reducing the concentration of greenhouse gases in the atmosphere. The aim of mitigation is to reduce the severity and frequency of climate change impacts, thereby protecting ecosystems and human societies.
This module will explore the basic concept of mitigation, the core mitigation strategies that we currently have available to us, the innovative action that is being taken around the world, and leading-edge ideas with regard to tackling the roots of climate change. By the end of this module, you will be able to critique the likelihood of implementation of many of these strategies, and will have a framework through which you can learn more about greenhouse gas management, both at home and around the world.
9. Climate change adaptation: dealing with the effects
In contrast to the previous module, this module introduces the idea of addressing the impacts of climate change rather than its causes. In particular, we will explore the various adaptation strategies that are available to be utilized around the world, the heated debate surrounding the equity implications of adaptation, and the linkages between adaptation and mitigation. By the end of this module we will have explored the difference between proactive and reactive adaptation, and our track record with both. We will outline the most common and effective adaptation strategies, including those related to human settlements, ecosystems, and the broader issue of development. Finally, we will explore the inevitable trade-offs between adaptation and mitigation, setting us up to finish this course with a survey of climate change response policies.
10. Policy tools for mitigation and adaptation
This Module forms a bridge between this first course in the Decision-making for Climate Change series, and the three courses that will follow. Given what we know now about the science behind climate change, and the strategies that we have at our disposal for responding to it, we can now be introduced to policies that bear this in mind. After being introduced to the fundamentals of mitigation and adaptation policy, we will use the British Columbia carbon tax and the proposed cap-and-trade system in the United States as relevant examples. Finally, we will finish with a glimpse forward to the future of climate change policy, and the most promising opportunities for both managing impacts and ensuring a rapid transition to a fundamentally low-carbon development path.
