[tex-live] Decline in multi-year ice in the arctic

"One of Canada's top northern researchers says the permanent Arctic
sea ice that is home to the world's polar bears and usually survives
the summer has all but disappeared.

Experts around the world believed the ice was recovering because
satellite images showed it expanding. But David Barber says the thick,
multiyear frozen sheets crucial to the northern ecosystem have been
replaced by thin “rotten” ice which can't support the weight of the
bears."

I wonder what "experts" they are referring to.  The experts at work
have been warning for years that satellites don't give a very complete
view of ice.  A thin layer of water on top of ice looks like open
water to the satellite, and new ice looks the same as old ice.
