you chose to cherry pick
No, i randomly picked in the forum search. I took the most recent ones. 
However, i'm not an expert on the topic. What's shaping my opinion on the topic is Munich Re. They have the best risk assessment money can buy, and they expect storms will cause more damage due to climate change.
I understand that they will expect more damage. However, that damage is a result of more people building in higher risk areas, and not greater storm severity. In the past, people did not build in flood plains, hurricane zones, and other areas of higher weather-related risks.
Looking more closely at Munich Re (which I agree is valid), they contend that the risk is largely due to increased flooding. I will agree that climate change is likely to increase precipitation, and consequently flood potential. However, increased precipitation does not correlate with storm severity. While the severity of storms is expected to continue its declining trend, rainfall associated with these storms is expected to continue on its upward trajectory. The same can be said for snowfall amounts, which depend largely on the availability of moisture.
We may be talking past each of with regards to storm severity. I consider other factors, winds, lightning, hail, tornadoes, etc., to be aspects of severity, while enhanced rainfall is not. Last year, Hurricane Florence made landfall as a category 1 hurricane, with winds of 90 mph. Conversely, Hurricane Michael made landfall as a cat. 4 storm, with winds of 155 mph. While Michael caused an estimated $8 billion in damage, Florence has been estimated at $22 billion, primarily due to the flooding caused by the rain. This is where data from Munich Re may be valid for insurance purposes, but does not necessarily correlate with storm severity.
