For the past few months, most of the cold air in the Arctic has been centered over Greenland. This means that it is not over Siberia. Sometimes it is the other way around. This is the normal condition for the Arctic – the cold tends to pool on one side or the other.
Either way, alarmists have devised a mechanism to keep the madness alive. When Greenland is warmer, they warn of meltdown and sea level rise drowning the planet. When Siberia is warmer, they warn of massive bubbles of methane that will consume the planet.
Antarctica has almost completely dropped off the AGW radar. Greenland is turning into an AGW train wreck. Look for the attention to turn back to Siberia.
