Climate change hurts the economy, according to a celebrated 2012 paper by economists Melissa Dell, Benjamin Jones and Benjamin Olken. That paper is in the top 1% of all academic economics publications by citation count, and it has received glowing coverage in the media. The authors teach at Harvard, Northwestern and the Massachusetts Institute of Technology, respectively, and have received some of the highest awards in the profession.

Climate change is now a driver of the world’s economy. The impact is profound:
- Catastrophic weather events — hurricanes, floods, droughts, high temperatures — are more frequent and more extreme. The cost can be measured in both the initial damage caused and the longer-term impact on the economy.
- Vulnerable communities are increasing climate-related investments, hardening infrastructure and taking other protective measures.
- Investment in carbon capture and storage technologies is increasingly rapidly.
- Governments are making investments and crafting regulations to reduce emissions of carbon dioxide and other greenhouse gases.
