Earth Set Bookclub: Plastic Inc: Big Oil, Big Money and the Plan to Trash Our Future
For November, Earth Set Bookclub turns to plastic – not where it ends up, but where it comes from, and the vast industry determined to make more of it.
Join us for dinner with Beth Gardiner, award-winning journalist and author of Plastic Inc., a deeply researched investigation into the oil and petrochemical companies behind the plastics boom. Gardiner follows the money, politics and industry strategy connecting plastic to the future of fossil fuels – and asks why, even as the world tries to use less, production is still accelerating.
As ever, an informal, probing and discussion-led evening around one table.
7pm–10pm
London – venue TBC
Tickets coming soon -

Should We Cool the Earth? – The Science, Politics and Ethics of Geoengineering
What if cutting emissions isn’t enough? As the planet gets hotter, an idea once considered fairly outlandish is being taken increasingly seriously: could we deliberately cool the Earth?
For October, Earth Set is getting to grips with the science of climate cooling. Could we reflect a small amount of sunlight back into space? Make clouds brighter? Put particles into the stratosphere? Would it work, how quickly – and what else might it change?
Joining us are Mark Symes, Programme Director for ARIA’s £56.8m Exploring Climate Cooling programme; Oliver Morton, senior editor at The Economist and author of The Planet Remade: How Geoengineering Could Change the World; Dr Colleen Golja, atmospheric scientist at Imperial College London; Alistair Duffey.
How do you test something like this without actually doing it? Could cooling one part of the world change rainfall or weather somewhere else? What don’t the models tell us? And beyond the science: should we ever use these technologies, who would control them, and what happens if one country decides to go it alone?
As ever, this will be an informal, probing and discussion-led evening, with plenty of time for questions, drinks and conversation afterwards.
6.30pm–9pm
📍 Octopus Energy & EV HQ, UK House, 164–182 Oxford Street, London W1D 1NN
