The senders and recipients of the leaked CRU emails constitute a cast list of the IPCC's scientific elite, including not just the «Hockey Team», such as Dr Mann himself, Dr Jones and his CRU colleague Keith Briffa, but Ben Santer, responsible for a highly controversial rewriting of key passages in the IPCC's 1995 report; Kevin Trenberth, who similarly controversially pushed the IPCC into scaremongering over hurricane activity; and Gavin Schmidt, right - hand man to Al Gore's ally Dr James Hansen, whose own GISS record of surface temperature data is second in importance only to that of the CRU itself.

They found that averaged sea surface temperatures over the MDR are the best predictor of Atlantic cyclone activity, followed by global average surface temperature, with MDR warming relative to the tropics being the worst predictor of hurricane activity (Figure 1).

«My interaction (over the years) with a broad segment of AMS members (that I have met as a result of my seasonal hurricane forecasting and other activities) who have spent a sizable portion of their careers down in the meteorological trenches of observations and forecasting, have indicated that a majority of them do not agree that humans are the primary cause of global warming.
