This section needs rewriting - it now reads as if it is the source that decides how many were insured, etc. Suggest that you remove "depending on the source" and make a decision about which source you find reliable. It is either 85000 or 145000 fatalities that are recorded, it can't be both. Chose one, and explain the definitions that are used. Alternatively, if you want to present the results from both the NatCat and the CATDAT databases, say which number comes from which, and explain the differences between the data. Without this guidance, it is very difficult for us as readers to understand why the numbers are so different, and how we should deal with that. This comes back again to the purpose of the report, and the messages that you want to bring forward - is it that there is a great difference between the data sets, or is it that there are great economic losses from climate related events?
Around 3% of weather and climate related events are responsible ...
What does "a reporting bias over time" mean in this context?
Basic information that is missing is teh number of events that have been counted. . Then you can explain (i) total economic damage,; (ii) fatalities ; (iii) backgound. But please add basic info
