A favorite alarmist obsession is September Arctic sea ice area.
During that month, the sun is very low in the sky in the Arctic, so the ice extent has almost no effect on the Earth’s SW radiative balance. Excess open water does allow more LW radiation to escape, which should make alarmists happy.
The high priests of AGW have decreed that vast amounts of ice during the rest of the year aren’t important.
