If the melting of the arctic sea ice is due to the planet warming, what is causing the antarctic sea ice to grow?
This new research also helps explain why observed changes in the amount of sea ice cover are so different in the two polar regions. The Arctic has experienced dramatic ice losses in recent decades, while the overall ice extent in the Antarctic has increased slightly. However, this small Antarctic increase is actually the result of much larger regional increases and decreases, which are now shown to be caused by wind-driven changes. In places, increased northward winds have caused the sea ice cover to expand outwards from Antarctica. In contrast, the Arctic Ocean is surrounded by land, so changed winds cannot cause Arctic ice to expand in the same way.

Honestly, I don't see the political will to change ever arriving.
What I wonder is if civilization as we know it will collapse. I think changes could be that big.
Food shortages will hit first. We are likely to see super storms that massively damage infrastructure.
The most fragile system is the economy. An Economic break down could start shutting down things before actual climate change.
Not without basically returning to a lifestyle equivalent to that of North American Indians
