Mark Serreze from NSIDC responds to Michael Mann’s scurrilous accusations, with even more scurrilous accusations.

“I’ve dealt with him before.”

He has dealt with me before.  In 2008, Mark Serreze predicted an ice-free North Pole that summer.

His prediction prompted me to write my first article about climate. “Arctic ice refuses to melt as ordered”

His prediction didn’t fare well, with lots of ice around the North Pole on the minimum date of September 9, 2008.

He did however inspire British swimmer Lewis Pugh to try to kayak to the North Pole.

“This year, for the first time, scientists predict that the North Pole could briefly be ice free and that has inspired Mr Pugh to try to find a way through.”

Mark Serreze also predicted an ice-free Arctic by 2030.
