Loss Of Multi-Year Arctic Ice During The Winter Of 2007-2008

Most of the multi-year sea ice in the Arctic blew out into the Fram Strait during the winter of 2007-2008.

    Why did it happen? Bad winds?
    How can we be sure that the “bad winds” won’t happen again?

    The Pacific ocean transported a mass of warm/hot water north to the arctic from 2003 to 2006 as part of a long term (decades) cycle. If you look at the SST plots, the year-round above average temperatures are peaking in 2004-2005. That water had enough thermal mass to melt a large region of ice and the positive feedback from summer insolation on open water exaggerated the amount of melt. The thermal capacity of air is too small to make much difference and is influenced more as a cause of those changes than actually effecting those changes. The open water also changed the regional Atlantis-v-Pacific pressure/weather patterns and a shift to the wind helped push the ice east to the Fram strait. What made this sequence remarkable is the coincidence of the long term ocean current cycles such that the Atlantic and Pacific made the warm water transport at roughly the same time.

    The open water resulted in enhanced “negative” feedback during the cool months, through the cooling cycle’s naturally induced convection to depths and evaporative cooling. It’s taken a while to release the excess heat. In the mean time there have been more dramatic swings in the ice area between summer and winter. This summer’s shift to ice remaining and aging in the western/Pacific side of the arctic suggests that the excess heat from that ocean cycle has been purged and the arctic will now slowly return to the more typical level of year-round ice cover.

    But Reggie said it fell victim to his blow thingy 😉

    Whatever happened to Reggie? And his blowtorch?

      Reggie was convinced of spiral meltdown. In fact most warmists were. Then he came smashing head first with cycles? We’ll have to wait and see but if we see.
