What is geoengineering ...

... is not a question I'm going to answer. If you're reading this then chances are very high that you're on my course, so you already well versed in geoengineering. Still, this short video provides a neat introduction to the concept, and was made in partnership with UCL. I encourage you to share it with friends and relatives who might not take such an interest in the environmental sciences, and then hopefully open up a dialogue with them about it.
