NASA Satellite Video: Changes In Arctic Polar Ice Cap

I've noticed the last three years have been colder than usual in spring (especially this spring). I think it's El Nino type water currents and air flow north into the arctic. Warm Pacific air moves across the polar cap, is conditioned - and then pours down the Hudson's Bay lowlands, to my house in Toronto.

To wit, a 25 year movie/video
of the North Polar Ice Sheet.

Look familiar? Don't get used to it...

From NASA's Looking at Earth page.

"This animation, derived from the Defense Meteorological Satellite Program (DMSP) Special Sensor Microwave Imager (SSMI), shows the annual minimum sea ice extent and concentration for 25 years, from 1979 to 2004."

Dam those
'El Nino type water currents and air flows north....'

By 2020, scientists calculate the ice cap will disappear
in summer.
