>The intensity, frequency and duration of North Atlantic hurricanes, as well as the frequency of the strongest (Category 4 and 5) hurricanes, have all increased since the early 1980s. The relative contributions of human and natural causes to these increases are still uncertain. Hurricane-associated storm intensity and rainfall rates are projected to increase as the climate continues to warm.
"It is premature to conclude that human activities–and particularly greenhouse gas emissions that cause global warming–have already had a detectable impact on Atlantic hurricane or global tropical cyclone activity."
So no detectable increase (even statistically, which I consider to be a much weaker requirement than actual subjective experience).

"Numerous data quality checks were used in this study, as noted above, and there are no known systematic errors in the observations or analyses that would be likely to produce the decreasing trend in TC #s examined here. This suggests the possibility that the downward trend may be associated with changes in environmental conditions. Studies such as Emanuel (2005) indicate that the changes in various different environmental conditions that are occurring due to anthropogenic influences are having an influence on TC activity in some regions of the world. In the Australian region, one possible physical explanation for a decreasing trend in TC #s could be a potential long-term shift in environmental conditions towards a more El Niño-like state, given that fewer TCs tend to occur in the Australian region during El Niño than La Niña conditions. Although the NIN and SOI data used here did not show a significant long-term trend, some studies suggest the possibility of a shift towards more El Niño-like conditions, relating to a possible weakening of the Walker circulation due to increasing atmospheric greenhouse gas concentrations (Vecchi et al., 2006; Power and Smith, 2007; Huang et al., 2013; DiNezio et al., 2013). However, it is also noted that considerable uncertainty exists in observed changes to the Walker circulation based on reanalyses (Compo et al., 2011)."
Therefore insurance premiums or losses may be difficult to compare year to year. Certainly insurances companies have factored global warming into their models and are changing their rates accordingly. To not do so would be grounds for shareholder lawsuits I should think.
There are as many climate deniers in insurance companies as there are atheists in foxholes. :>

I wouldn't be shocked if cat five hurricanes became pretty common in a couple of decades due to warmer waters, and one or two of those a year would devastate coastal economies.
But I'm not a weatherman...
Here's a page with good, updated information about global warming and hurricanes: https://www.gfdl.noaa.gov/global-warming-and-hurricanes/
I read no condescension in it.
Though the timescale will likely be on the order of decades or centuries, not 20 years.

So we do have proof of weather changes causing earthquakes.
Though I doubt anyone has data or models that would be useful for this tangent. At least for oceanic fault lines, which could be affected by ocean rise.
