Antarctica is responding quite differently because in an ice sheet covered continent completely surrounded by ocean, compared to the Arctic which is an ocean mostly but not completely surrounded by land. As a result, Antarctica is, for much of the year, mostly in it's own world with much more limited connection to the mid-latitudes than the Arctic is even in winter. Of course, the northernmost area, the Antarctic Peninsula is warming rapidly.
Thanks, Rick, for your sincere and downright scholarly efforts! I track C3S "Climate Pulse" and their other publications, including a recent post announcing a 0.4 degC GAST increase over the past 2 yrs. (1991-2020 baseline), so 1 full degC every 5 yrs at this rate (0.2 degC/yr.), 2 degC by 2027, 3 degC by 2032, and the extinction level 6 degC by 2047, the year any child born today among the 108,000 fellows will celebrate (?) his/her 22nd BD. I'm just crazy enough to wonder whether or not the seeming madness in DC is the billionaires realizing what's coming and attempting to raid the US Treasury before moving underground or rocketing off to Mars. Hmmmm?
Moving to Mars won't work and staying here won't work either. Even if everything was to go optimally it will still take 500 years or more for the planet to cool back down. Imagine Earth as a baked apple too hot to the touch- after 500 years it may cool down but it won't be the same planet as it was before it went into the oven. Just like the once juicy apple.
I know it's outside your remit Rick but is a similar warming going on in the south polar region 60° southward?
