Columbia Business School’s Professor Gernot Wagner spoke with Associated Press reporter Alexa St. John about a new analysis from the Potsdam Institute for Climate Impact Research detailing the potential economic damage of climate change under current global emissions trajectories. Wagner explained that the report’s findings—showing trillions in projected losses—underscore how climate risks compound over time, affecting productivity, infrastructure, health, and long-term growth. He emphasized that the cost of inaction far exceeds the investment required to transition to a low-carbon economy, framing climate policy as both an environmental and an economic imperative.
