this is the closest i can find to what he is on about

"Arctic summers ice-free 'by 2013'
Their latest modelling studies indicate northern polar waters could be ice-free in summers within just 5-6 years."
so erm close but not quite
meanwhile :
"The 2017 sea ice level fits with an overall steady decline over the decades, but one that varies from year to year, Scambos said. “It’s not going to be a staircase heading
down to zero every year,” he said. “[But] the Arctic will continue to evolve towards less ice. There’s no dodging that.”
also kids remember "all models are wrong but some are useful"
