Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
The analysis of twenty-two disaster loss studies shows that economic losses from various weather related natural hazards, such as storms, tropical cyclones, floods, and small-scale weather events such as wildfires and hailstorms, have increased around the globe. The 10 studies show no trends in losses, corrected for changes (increases) in population and capital at risk, that could be attributed to anthropogenic climate change. Therefore it can be concluded that anthropogenic climate change so far has not had a significant impact on losses from natural disasters.

I note that the Conclusions section of that article continues, with my emphasis:

Considerable uncertainties remain in some of these studies, as exposure and vulnerability that influence risk can only be roughly accounted for over 15 time. In particular the potential effects of past risk reduction efforts on the loss increase are often ignored, because data that can be used to correct for these effects is not available. More insight in the relative contribution from climate change on disaster losses could potentially be gained from studies that attempt to project future losses. These studies can assess the impact of future climate change, which is projected to be much 20 larger than the change so far observed. The discussion above shows the need to include exposure and vulnerability changes in future risk projections, which clearly contribute substantially to changing risks.
