How much does our increasing dependence on cloud technologies add to the digital carbon footprint? 

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.
