CO2 is absorbed by the ocean and transfers the heat it held into the water thereby melting the ice.
CO2 doesn't transfer hear into the ocean worth a hill of beans, it is negligible!
There is an active VOLCANO right by the Thwaites glacier!

Volcanic activity under Thwaites Glacier contributes to melting

Excerpt:
The Thwaites Glacier in West Antarctica has recently attracted considerable media attention, as scientists have predict it to collaps largely in the future. It is up to 4 kilometres thick and large enough to contribute with 1-2 metres to global sea level rise – a dramatic value. So far, warm sea water has been made responsible for glacier melting on the coast, but now there is evidence that a significant part of melting actually takes place at the glacier base, away from the coast. Thwaites Glacier is largely based well below sea level, as is the case for large parts of the West Antarctic ice shield, a fact that contributes to its lack of stability.

There is one for Pine Island Glacier too:

Tracing a chemical signature of helium in seawater, an international team of scientists funded by the National Science Foundation (NSF) and the United Kingdom's (U.K.) Natural Environment Research Council (NERC) has discovered a previously unknown volcanic hotspot beneath the massive West Antarctic Ice Sheet (WAIS).
