Why are we seeing more frequent costly weather events?
There are two main reasons for this increase in billion-dollar weather events. The first, of course, is climate change. The overall warming of the Earth does lead to increases in extreme weather, including hurricanes and fires. Earthquakes are the outlier that are not influenced by climate change, but notably no earthquakes contributed to the billion-dollar disasters this year.
While global climate change is a major cause of the increase in large storms and fires, it’s likely not the only reason for more expensive disasters. The amount in damages is not adjusted for inflation, and the costs for repairs and rebuilding have definitely increased.
For example, consider just the cost of replacing the roof in the event of a hurricane or hail storm. According to one source, the average cost of roof replacement for an average-sized home in 2023 is $11,500[2]. However, in 1990, the average cost of a roof replacement was only $3,500[3]. As you can imagine, when you’re talking about hundreds or thousands of damaged buildings, these differences can rack up quickly.
