It would be nicer in many ways if we could just use the natural ice sheet, but AFAIK by now we cannot rely on it, even if we magically removed all the political problems and suddenly started doing the right thing. Based on available information it's possible, or plausible, that irreversible processes are already under way. I'd say the priority should be against the threats to the existence of people. Consequences for the main guilty parties is an important but separate issue. I do hope that this whole crisis could contribute to curbing corporate power (by gaining widespread popularity and push for this, among young people especially). But the priority is keeping the patient alive, because without this the question of also making them a good person is moot. edit: I also think based on the descriptions that some of the ideas could be straightforward enough to just be executed by government services (akin to firefighters or coastal guard) without any contractors, but this more of a question of how the governments function, possible corruption etc.
