But why not make the data as unbiased as possible? Why not show total cost for weather events as a percentage of GDP?

Or if only large-scale catastrophes have increased, the distribution of weather events?

Or maybe the percentage of houses destroyed or the total acres of land rendered temporarily useless?

Or number of weather-related casualties per capita?

While none of those are perfect or complete measurements, they'd all dodge several issues discussed here.
