I don't know if I would call the path Sandy took as extra-ordinary, in fact, my point is that Sandy was not extra-ordinary.
What was predicted, and what records are starting to show is that hurrican activity in the Atlantic is in fact increasing. It is only logical to
speculate that this increase in hurricane activity will increase.
Observed records of Atlantic hurricane activity show a strong correlation, on multi-year time-scales, between local tropical Atlantic sea
surface temperatures (SSTs) and the Power Dissipation Index (PDI) (Figure 1). PDI is an aggregate measure of Atlantic hurricane activity, combining
frequency, intensity, and duration of hurricanes in a single index. Both Atlantic SSTs and PDI have risen sharply since the 1970s, and there is some
evidence that PDI levels in recent years are higher than in the previous active Atlantic hurricane era in the 1950s and 60s.
And I would add that global temperatures spike after WW II, and could be an explanation for the high level of hurricanes in the 50ties.
There is ample evidence that GW is caused by modern industry, but it is not yet conclusive. While our ability to study GW in the past is limited,
technology does provide us with the tools to look back through the history of our planet, so while GW has only been studied for a a few decades how,
we are also able to look back through history to expand on our knowledge.
I am willing to consider realistic alternative reasons that might be causing GW, but many what the GW deniers throw out is a lot of propaganda, with
trumped up claims, twisted versions of studies, and cheap smoke and mirror tricks, which is not worth the attention. I'm all for healthy skepticism,
but that is not what GW deniers provide.
