Don't wanna downplay the seriousness of an ocean current collapse, however, articles covering this Danish study seems to grab the "we're gonna die soon"-angle by default. Danish media has found other scientists that do not quite accept the conclusion based on methods used. E.g. this abstract summarized by ChatGPT:
> Climate scientist Steffen Malskær Olsen (specializing in ocean currents at the National Center for Climate Research under DMI) questions the predictions made by Peter Ditlevsen and Susanne Ditlevsen (authors of the study) about a potential collapse of thermohaline circulation. He cites limited data and uncertainty about the correlation between surface temperatures in the Northwest Atlantic and the thermohaline circulation as main concerns. Despite this, he acknowledges the study's importance for demonstrating the potential of advanced mathematical models in predicting climate phenomena. He believes that the IPCC's prediction, which deems a collapse highly unlikely, remains the most reliable. Peter Ditlevsen accepts this uncertainty, arguing they are working with the best data currently available. (https://nyheder.tv2.dk/klima/2023-07-25-danske-forskere-med-...)
