Climate crisis is one of the grand challenges we face as a society, but it can be hard to approach as a subject. Not only can the science at times seem dauntingly complex, but the solutions are also far from clear. This leaves many people feeling confused, guilty, anxious, angry, or else completely switched off from the subject. This course tells the story of climate science in a new way, to find a fresh perspective for thinking about the future. It looks at the problem through the lens of climate engineering - the idea of deliberately trying to modify the climate, to counteract the changes we’re observing and predict what will happen in the future. The subject contains everything from hope – new technologies that could prevent the worst impacts of climate change – to enormous controversies over their risks and the way they could be used. More than that, climate engineering serves as a useful tool to move beyond the usual, often frustrating conversations around what to do about the climate crisis. By examining exactly what we want for our planet's climate, and what we would be willing to sacrifice to get there, we might find more clarity in our search for solutions.Learn more ❯Could we control our climate?
This free course, Exploring economics: the secret life of t-shirts, aims to describe what goes into making and selling t-shirts. Which resources, which markets, who is involved, the income people get, the income and value they create are all discussed. You will explore these questions at different stages of the production of a t-shirt, and you'll use concepts from economics such as 'supply chains' or 'value added' to answer them. The course will be described using data. You should think about key numbers and data which help constructing evidence of how a t-shirt is produced, from raw cotton to our wardrobe.Learn more ❯Exploring economics: the secret life of t-shirts
Energy resources are essential for any society, be it one dependent on subsistence farming or an industrialised country. There are many different sources of energy, some well-known such as coal or petroleum, others less so, such as tides or the heat inside the Earth. Is nuclear power a salvation or a nightmare? This free course, An introduction to energy resources, provides background information to each, so that you can assess them for yourself.Learn more ❯An introduction to energy resources
What affects the atmospheric and ocean flows? This free course, Environment: understanding atmospheric and ocean flows, explores the mechanisms that are important; the most rapid carrier is the wind. The basic principle of global atmospheric circulation is simple: warm air rises and cold air sinks. How does this principle affect the atmosphere and flow of water in practical terms? Starting with an iconic environmental icon, the polar bear, you will learn how global flows of water, heat and pollution are affecting the Arctic region and changing our world.Learn more ❯Environment: understanding atmospheric and ocean flows
What is ecology and why is it important to our understanding of the world around us? This free course, Introducing the environment: Ecology and ecosystems, looks at how we can study ecosystems to explore the effect that humans are having on the environment.Learn more ❯Introducing the environment: Ecology and ecosystems
Effects of pollutants on the aquatic environment is a free course. It begins with an introduction to water and goes on to briefly outline the major sources of water pollution (these being sewage works, manufacturing and industrial plants, the farming and animal husbandry sectors, landfill sites and urban surface water run-off). It considers the major water pollutants and describes the effects they have on water.Learn more ❯Effects of pollutants on the aquatic environment
This free course, The science of nuclear energy, will delve into the science behind nuclear power and explain what happens inside a nuclear reactor and what it means for an element to be radioactive. It will explore some of the risks of producing nuclear power and examine the arguments for and against including it in future energy planning as well as looking at other potential future solutions.Learn more ❯The science of nuclear energy
The search for sustainable energy will dominate the twenty-first century. This free course, An introduction to sustainable energy, provides an introductory overview of the present energy systems and takes a brief look at where the world may find energy in the future - cleaner use of fossil fuels or renewable energy sources?Learn more ❯An introduction to sustainable energy
Maybe you already have some awareness of the issues at hand but feel unsure about what to do or where to start when it comes to taking action.

We ask the question ‘Can renewable energy sources power the world?’ as a response to the growing awareness that increased use of renewable energy technologies is making a major contribution to global efforts to limit anthropogenic climate change. The course begins by examining the environmental concerns that have caused a rise in interest in renewable energy, introducing the main sources and technologies, and describing global efforts to increase the share of renewables. The course then looks at each of the principal renewable energy technologies and the contributions they might make to global energy demand. Finally, several future energy scenarios are analysed to show how combinations of renewable energy sources and technologies could provide a major share of global energy needs.Learn more ❯Can renewable energy sources power the world?
Human societies have to take urgent action to end their dependences on fossil fuels.
