Do we really think a century of data is a lot? Especially when you are talking about ~20 events per year?
Can you explain why 1850 looks comparable or worse than the 1990s and worse than 2010s so far? I don't see what this proves.
The inputs for "man's impact" in the 1850s would not come close to modern day. If we took that into account, by your logic, the bar charts should explode out the top! But it doesn't. Not even close.
1850 - 1.2B people
2010s - ~7B people and a lot more pollution
From your linked data, the impact of AGW on hurricanes over the last year = 0
Edit: I think you may agree with me that it doesn't point to more extreme weather events. If so - my comment is directed at the parent.
