Ice Shelves Advance,
It is claimed that anthropogenic CO2 emissions from burning fossil fuels are responsible for amplifying warming ("polar amplification") and ice melt in polar climates, consistent with pronouncements pertaining to anthropogenic global warming.
About 85% of the East Antarctic Peninsula ice sheet has sustained "uninterrupted advance" since 2003 (Christie et al., 2022).

(cf. Supplementary Discussion 3).

ocean wave-induced ice-shelf frontal damage.
Note that, unlike the EAP's other ice shelves,
Ronne Ice Shelf is immune to the influence of
damaging ocean waves given its thickness
East and West Antarctica have been significantly cooling since 1979.
Overall cooling rates of -0.7°C and -0.42°C per decade from 1979 to 2018 indicate -2.8°C and -1.68°C total cooling, respectively, for the mainland continent during these decades (Zhu et al., 2021).
