Why is the Arctic melting, but the Antarctic doing great? That's what the latest IPCC report says (p. 2-192 of the Physical Science Basis provides a time series), but it says nothing, unless I missed it, on the causes of such a discrepancy. It's same ice, isn't it? Why is Antarctic ice more heatproof?
EDIT: I've found the answer in the IPCC report (AR6 WGI), and it's even fairly intelligible (unlike much of the rest of the report). Start reading from page 7-80, if you're interested
