That would not be a 'global' event, just regional.
The austral summer is interesting:
* W. Peninsula air temps are up more than 10-F.
* 596 of 674 glaciers are retreating
* Warm water is melting glacier grounding lines from below.
* Often above freezing
* Ice melts sooner and freezes later
* Winds blow snow off continent before it can freeze into new ice.
* dark vegetation amplifying warming
* exposed rock amplifying warming
* exposed sea water amplifying warming
* Adelie penguin eggs are drowning in ice melt and rain.
* Chicks dying of exposure
Leopard seal killing more than half newborn fur seal pups.
* Atlantic Silverfish, which dominated the marine food supply has collapsed.
* Sea ice, which hosts algae, which feed krill is under assault.
* The ice shelf which 'corked' the Thwaites Glacier is unstable, and we may see 5-feet of sea level rise from this single system within 5-years
