Arctic Sea Ice Heads for Record Low as Melt Exceeds Forecasts - Bloomberg
“Now that we’re getting into the guts of how quickly the sea ice will go, it’s important to know the thickness,” said Pen Hadow, who in 2003 became the first person to trek solo and unassisted to the North Pole. “It’s become much more of a volume issue: area times thickness.”

Hadow in February plans to begin a 120-day traverse of the Arctic Ocean from Russia to Canada during which he’ll measure the thickness of the ice and make observations about ice ridges that form where ice floes crash together...
“In some areas of the Arctic sea-ice, up to 40 percent of the volume is held in narrow vertical ridges where ice floes have crashed together,” Hadow said in a telephone interview. “Knowing how many ridges there are and knowing their height is increasingly interesting as we ever refine our models.”

Note the El Nino, characterized by warmer than average water temperatures along the Equator in the Pacific Ocean. Note also the cold Pacific Decadal Oscillation (PDO), which looks like a backwards “C” of cold water from Alaska down the West Coast and out to Hawaii (coolest water around Hawaii in at least 3 years). When you have a cold phase of the PDO, you tend to get more frequent La Ninas and you tend to get weak-moderate El Ninos, instead of the strong El Ninos like we had in 1982-83 and 1997-1998. The water temperature has been warmer than average over much of the Arctic, where the icecap has been shrinking – and colder than average over the Antarctic, where the icecap has been growing. The South Pole set a record low temperature of -100.8F.

[Chris Searles, drummer for some band] Global Warming / Climate Change represents the end of biology at global scale in our lifetimes. Bumm-er. ...I think we environmentalists tend to see everyone outside our movement (or “worldview” if you will) in a religious-y sort of way. “Are you a believer?” “Are you a follower?” “Well come get saved/enlightened/etc.”
