24 Carbon of Contention

My guest is Dr Muireann Lynch of the economic and social research institute here in Ireland. She very carefully guides me an idiot on my first tour of the c-word. Carbon. How much it costs to use it, how much it costs, the maths of optimisation, Lagrange multipliers, carbon offsets, what happens when carbon has an infinite price. Warning – this contains traces of calculus that some listeners may find upsetting. But stick with it and we eventually get onto lighter topics like making twixes or other nougat-biscuit equivlants and then of course the end of habitable earth.
