One other note, the artic is still teeming with life presently. Muskeg peat bogs are prevalent throughout the region. When the AlCan highway was built, it wasn't uncommon to lose a D9 'dozer completely during the summer months. They sank to the bottom of the bogs. These bogs also emit copious amounts of methane as the temps creep up. Methane is another factor newly being studied. It is much stronger greenhouse gas than CO2.
Ennywho, another science denying thread bites the dust.
