So regionally this happens all the time, though depending which way the wind blows during a season, there may very be ice at the beach.

Ice at the poles does not change the amount of radiation reflected out of Earth's system near as effectively as ice at low latitudes.

That's melting the ice at both poles, increasing sea levels.

The sea ice at the bottom of the world is at record low levels and still plunging.

So, ice at the North Pole has melted and formed a freshwater lake.

We don't really know the magnitude of that lag as well as Barton implies we do, because it is very challenging to put CO2 records from ice cores on the same timescale as temperature records from those same ice cores, due to the time delay in trapping the atmosphere as the snow is compressed into ice (the ice at any time will always be younger older than the gas bubbles it encloses, and the age difference is inherently uncertain).

The ice at the GISP2 site in central Greenland was only one ice age thick before they hit rock, (as opposed to Antarctica where the ice is more than 6 cycles 700,000 years thick) indicating that ALL the Central Greenland ice melted during the previous warming cycle (125,000 years ago).

This report describes simulations of future sea - ice extent using the NCAR CCSM3, which point to the possible complete loss of sea - ice at the end of the melt season as soon as 2040.

Excellent post.Take that factor down by 10 to complete deglaciation and loss of all ice at poles within 100 years.

RE no ice at the North Pole or other symbolic, localized effects of GW that might inspire us to action.

There have been a few moments — like when I was standing too close to an open - water gap in the floating sea ice at the North Pole, until a bearlike Russian camp worker pulled me back, explaining in broken English that a tourist had fallen into the 14,300 - foot - deep, 28 - degree water that way the year before.

Just like (in theory) going to see the Rolling Stones, it may well soon become a once in a lifetime chance to stand on the ice at the North Pole.

But even taking the long view, the trends are towards less and less ice at the poles.

This means that in previous post ice age warming cycles, the Arctic ice at the GISP2 site in central Greenland DID actually ALL melt.

James Hansen of NASA echoed Dr. Crowley, saying that as long as we're technologically able, we'll be able to keep the big ice at bay.

The presence of ice at the North Pole is a fairly strong indicator that the ice at the North Pole had not melted.
