"We are witnessing a true reversal of ocean circulation in the Southern Hemisphere—something we’ve never seen before,” explains Antonio Turiel, ICM-CSIC researcher and co-author of the study. “While the world is debating the potential collapse of the AMOC in the North Atlantic, we’re seeing that the SMOC is not just weakening, but has reversed. This could have unprecedented global climate impacts.”
That was my physics teacher.
“So materials shrink as they get colder.”
“Ma’am, doesn’t ice expand?”
“We don’t talk about that.”
Ice doesn’t expand. Ice as a solid shrinks when getting colder. H2O expands during phase transformation from liquid to solid.
