Even The DNA Of Single-Celled Plankton Can Upend Alarmist Arctic Sea Ice Melt Claims

New research utilizing the DNA of dinoflagellate (Polarella glacialis) indicates that, 14,000 years ago, when the atmospheric CO2 concentration is thought to have been 230 ppm, the studied Arctic region (Yermak Plateau) was sea ice-free year-round.
“Around 14.0-13.9 cal kyr BP, a short-lived year-round, ice-free, open ocean occurred.”
During the Early to Middle Holocene (10,000 to 4,000 years ago), Arctic sea ice was seasonal, dominated by first-year ice that did not survive the summer melt season.
“The Holocene Yermak Plateau is characterized by a seasonal sea ice cover, which my consist mainly of first-year sea ice … a large part of first-year ice, as opposed to seasonally drifted multi-year ice.”
Today, at 430 ppm CO2, Arctic sea ice is increasingly first-year, but a “multi-year environment” persists. Multi-year sea ice has survived at least one summer melt season, and it continues to thicken over multiple years.
