The sad deaths from flooding in New York are already being used as climate porn, with claims of “historic”, “1000 year floods” and “made worse by climate change” already being bandied about. No doubt we will see a fraudulent climate attribution being rushed out in the next few days.
But what do the actual facts tell us?
The main highlights are:
The Guardian absurdly claim that New York never has hourly rainfall of 1.94” before this year. But how long has Central Park actually been recording hourly rainfall? Like most weather sites in the US, only daily totals were recorded for most of the past.
To put this claim into context, the hourly record for the UK is much more, 3.6”, which was set in 1901 in Maidenhead, hardly the sort of place that gets hit by tropical storms regularly!
Secondly, the total rainfall from Ida, which was spread over two days, was around 7” in New York. NBC reckon an average of 5.67” for the TriState of NY, Connecticut and New Jersey:
There is nothing “record breaking” about any of these numbers. The official 24-hour record for New York is 13.57”:
At Central Park, the daily record of 8.28” was set all the way back in 1882:
Indeed over the two days of that storm in 1882, more than 10” fell:
More importantly though, the CLIMOD chart above shows that heavy rainfall events are not getting worse. Unfortunately the Atlantic coast occasionally gets hit by a brute of a storm. Arguably one of the worst was Hurricane Diane in 1955.
After making landfall in North Carolina as a Category 3 storm, one of three hurricanes to hit North Carolina that year, Diane turned northwards, leaving devastating floods in its wake. Connecticut was worst hit with 12” of rain in 24 hours, and 20” over two days, more than double the total from Ida this week:
Just take a look at this video of Diane, and pray we never see its like again:
