Now he appears to be doing the same with hurricane activity, and the new work is not without its detractors.
“The paper comes to very erroneous conclusions because of using improper data and illogical techniques,” said Chris Landsea, science and operations officer at the National Hurricane Center.
In his criticism, Landsea notes that the paper begins by saying that Atlantic tropical activity has “reached anomalous levels over the past decade.”
This ignores recent work by Landsea and a number of other hurricane scientists who found that storm counts in the early 1900s — in an era without satellites and fewer seaborne observers — likely missed three or four storms a year. The addition of these storms to the historical record, he said, causes the long-term trend over the last century to disappear.
“This isn't a small quibble,” he said. “It's the difference between a massive trend with doubling in the last 100 years, versus no trend.”

Even one of the IPCCÂ’s lead authors sniffed a problem:
‘This looks like a pretty good analysis, but I have to say I remain somewhat skeptical,’ Kevin Trenberth, climate analysis chief at the National Center for Atmospheric Research said in an e-mail. ‘It is hard to make data where none exist.’
Well, yes. But then the invention of data that does not exist and the obliteration of data that does exist has been precisely how the man-made global warming scam has been perpetrated right from the get-go. The most egregious example of this was the piece of ‘research’ that underpinned the entire IPCC/Kyoto shebang from 2001 when it was published -- the so-called ‘hockey stick’ curve, which purported to show a vertiginous and unprecedented rise in global temperature in the 20th century

ust when you think it couldnÂ’t get any more bizarre in Mann-world, out comes a new paper in Nature hawking hurricane frequency by proxy analysis. I guess Dr. Mann missed seeing the work of National Hurricane CenterÂ’s lead scientist, Chris Landsea which we highlighted a couple of days ago on WUWT: NOAA: More tropical storms counted due to better observational tools, wider reporting. Greenhouse warming not involved.
Mann is using “overwash” silt and sand as his new proxy. Chris Landsea disagrees in the Houston Chronicle interview saying: “The paper comes to very erroneous conclusions because of using improper data and illogical techniques,”
Mann hockey-sticks hurricanes: Hurricanes in the Atlantic are more frequent than at any time in the last 1,000 years « Watts Up With That?
Please tell me your not still touting Dr. Mann's "hockeystick" as the bible for the marketing theory known as man made global warming. The fact's are this theory has been debunked so badly that the IPCC will not even use data on it that is less than 120 years old. and who knows what the new IPCC report will hold, perhaps evidence of alien life in our TV sets making us all have to run to turn to 3D TVs or risk being taken over by the TV people. Man made Global warming is a wonderful way to create a need for a market where none existed, and once done to serve that market. Need an example, you need look no further than G.E.
