The Pursuit of Truth: Fixes for the Spread of Online Mis/Disinformation

Author: Anya Schiffrin

The European Union has politically agreed on the world’s most far-reaching attempt to rein in the powers of Artificial Intelligence. At the heart of the matter is the dangers posed by generative AI systems like ChatGPT to produce text, spread dis/misinformation and fake news virally, and create illegal content. The global information ecosystem, in short, is at a crossroads. In this new study, Anya Schiffrin, director of the Technology, Media, and Commu­nications at Columbia SIPA, examines the promise and pitfalls of demand-side (awareness raising, fact-checking) versus supply-side (government regulation, content moderation) solutions to ensure a healthy ecosystem of information while also maintaining freedom of expression.

Addressing the 'Wicked' Problem of Climate Change

Authors: Joseph Stiglitz, Scott Barrett, and Noah Kaufman

The COP28 summit in Dubai revealed the difficulties of finding global consensus around climate change, a “wicked problem” that defies easy solutions. Early prescriptions for climate solutions focused on idealistic "optimal" policies and all-encompassing global treaties. With global emissions still climbing, more radical reductions are needed sooner and new approaches to promote global collective action. In this IGP report, three Columbia economists — Joseph Stiglitz, a Nobel Laureate in economics, Scott Barrett, a leading climate economist, and Noah Kaufman, a former White House senior advisor on climate economics — describe a more nuanced, realistic, and strategic vision for climate progress.

Food Systems Transformation: Policy Solutions Toward a Food-Secure World

Authors: Glenn Denning, Jessica Fanzo, Ermias Kebreab, Jyotsna Puri, and Wolfram Schlenker

The global food system is failing to meet its most fundamental objective: to provide access to affordable, healthy, and safe diets, styming progress on ensuring food security for all people at all times. This publication lays out an evidence-based strategy for achieving universal food security and provides recommendations in how and where we produce, distribute, and consume food in an adversely changing climate.
