strange how your man uses stats to suit his own ends?..eg 7.8c in 1696 to 10.0c in 1732 a rise of 2.2c in just 36 years..then compares this to 0.6c in the last 100 years!..well if you compare 8.4 in 1963 and 10.6 in 1990 i can do the same in just 27 years!..most of what he writes uses very carefully selected data to prove a point and ignores everything else, not very well balanced or presented! However i do think there is some mileage in solar activity and global cooling how much though is another matter.
