Oldest/Thickest Arctic Sea Ice Has More Than Doubled Since 2012

Mark “Death Spiral” Serreze at NSIDC always puts a graph of multi-year ice in his April sea ice news. The point of this graph is to show how old/thick ice is disappearing from the Arctic. This year he forgot, so I decided to chip in and lend a hand.

The percentage of sea ice five or more years old has more than doubled since 2012.

    Has Mark “Death Spiral” Serreze at NSIDC expressed his appreciation for your assistance?

    But it is still warm and dry in Los Angeles! The world is going to end! Think of all the unhappy reality TV stars in peril there! 🙂

  3. Lotta good that ice does to California. The arctic is local, not global. California is global.

    It’s just old rotten ice. 😉

    Yes, it is snowing in Northern California and Oregon as well as Utah, etc.

    Not to mention here on the East Coast, more snow/ice this week!

    If the trend continues then in only 20 years 25% of the Arctic Sea ICe will be over 5 years old.

    Can I have a research grant to link this to CAGW?

    Who needs Arctic ice? Not polar bears or me. Bring on the warming! A few millennia of the Holocene Optimum revisited.
