Climate Change Is Breaking Insurance. Here’s How Tech Could Save It. - WSJ

If floodwaters outside a warehouse in Freeport, Texas, owned by private investment firm Postlane Partners rise to 8 inches, an internet-connected sensor will trigger an automatic $3 million payment from an insurance company, a startup called FloodFlash. If the waters rise to 16 inches, the payment will also rise—to $5 million.

This type of policy, called parametric insurance, works like a bet. It has a defined payout, which limits the liability of the insurer. And it comes from a new breed of insurance company, stepping in to shoulder risks that traditional insurers can’t—or won’t—take on, because climate change has made more typical kinds of coverage unprofitable.

State of Play

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. 

On top of all of this is the cost of uncertainty. As the Fourth National Climate Assessment, released in 2018 by the U.S. Global Change Research Program, says, “The assumption that current and future climate conditions will resemble the recent past is no longer valid.”
