Climate change is a major economic threat. With a new model, economist Andrea Titton shows how climate disasters can disrupt supply chains, how climate tipping points may cost trillions each year, and how international fairness is also at stake. But, he says, being better prepared now will actually prove cheaper than taking the gamble of hitting a climate tipping point. On Thursday, 2 October, Titton will defend his Ph.D. thesis at the University of Amsterdam.
