Hurricane Risk Analytics

Hurricane Risk Analytics

It’s hurricane season, again. And that must mean that we face more loss, more costs, and yet more debate. Even if we disagree about what drives more CO2 in the atmosphere, it’s there, it’s increasing, and it’s making us hotter (Fourier predicted a Greenhouse Effect in 1824, quantified by Arrhenius in 1896). It’s getting absorbed in the oceans, making it hotter as well (see Figure 1). There are likely many other drivers of the specific nature of Hurricane behavior, but the impact of rising ocean temperature appears to be fundamental (see National Geographic, Sept 2018 and Inside Climate News, June 2018). Figure 1 is a mash-up of EPA and Wunderground Hurricane data, aggregated by decade (see References). I imagine insurance companies are interested in, and active with, this type of analytics, if our government officials are not (see Science Alert, Sept 2018).

So, we’ve evidently established there is a risk, and it appears to be getting greater: more storms…even more loss and even greater costs. In a data-driven decision-making world, we would have healthy debates about proper and proactive mitigation measures we can take to limit the risk. Our business, environmental, energy and infrastructure plans must be open-minded to these real risks. There’s an informed balance we can strike that can help us optimize the economics in light of the facts. Check out the data for yourself.

Something to look into, check out the flood insurance the US govt pays to home owners. Some homes in certain areas experience 100 year floods every 3-5 years. They cost tax payers a few million dollars rebuilding $250,000 homes.
