1. Separate papers found the Southern Ocean overturning circulation had slowed by about 30% since the 1990s and could drop off much further by mid-century due to meltwater from the continent’s ice sheets if greenhouse gas emissions were not significantly reduced. Scientists said this could generate a cascade of impacts to push up sea levels, alter weather patterns and starve marine life of a vital source of nutrients. Past changes in ocean circulations have happened over more than 1,000 years. The paper said in this case it could happen within decades, with relatively abrupt consequences for lives and livelihoods.

2. ”Not prepared” as in this hasn’t been modeled on a regional basis (in IPCC, NGFS etc climate scenarios) – or that it has been modeled, but government/corporates are not running appropriate climate scenario anlaysis? The article wasn’t really clear on this point
