... that in the North Atlantic, open ocean convection, the mixing of deep and surface waters that plays a crucial role in global climate, has decreased in response to global warming? Sources: "Open-ocean deep convection...occurs at only three known northern hemisphere sites...as well as in the Weddell Sea...These sites, of small geographical extent, are of great importance for ocean climate." (Wadhams et al 2002), and "In EC-Earth [an earth system model], just as observations suggest, LSDC [Labrador Sea deep convection] is subject to unpredictable and strong variability, with the resumption of deep convection after shutdowns of sometimes several years. Note that the likelihood of shutdowns of about one decade in the model increases with global warming (Fig. 6), but seems to be underestimated with regards to observations. For example, Yashayaev and Loder (2009) showed that 2008 was the first year with deep convection in the Labrador Sea since 1994" (Brodeau and Koenigk 2016).
ALT1:... that open ocean convection, the mixing of deep and surface waters, plays a crucial role in global climate?

Free of copyright violations, plagiarism, and close paraphrasing: - mostly, but this sentence "low-frequency variability of the NAO. The decline is primarily caused by a decrease of the sensible heat loss to the atmosphere in winter resulting from increasingly warm atmospheric conditions." should probably be rephrased as it is identical to an article.
Other problems: - There is a Lead Rewrite tag. I'm not sure if this affects DYK nomination process. But it is a very technical article.
Hook: Hook has been verified by provided inline citation
Overall: I personally prefer the ALT1 hook. There is a tag on the article that it is overly technical (and I agree with that), but I don't see that tag listed at WP:DISPUTETAG. Can dandelion11 or Chidgk1 or Rotideypoc41352 maybe rewrite the lead paragraph so that it is less technical? Also see the sentence above that was flagged in the CopyVio report, which should be rewritten. I welcome another reviewer's opinion about whether the Lead Rewrite tag is a barrier to the DYK nom.

@Chidgk1: ok -- I'm not sure that the tag prevents a DYK, so I'm fine approving it & letting one of the people who move it past this stage decide. But, I do think the sentence that showed up on the Copyvio report (above) needs to be rewritten before moving this nomination forward. QuakerSquirrel (talk) 15:11, 8 June 2021 (UTC)[reply]

I'm approving this with the note that the lede is overly technical, but I don't think that prevents DYK approval. Again, I prefer ALT1. Thanks for edits, Rotideypoc41352. QuakerSquirrel (talk) 16:22, 8 June 2021 (UTC)
