Is it responsible to publish a paper that may diminish the threat of global climate change?

It is not a scientist's job to apply a political filter if the scientific basis is sound and it improves our understanding in a field.

Article is paywalled. I assume it is a response to this [1] discussion from earlier. The linked article appears to be about iceberg calving events. Does it deal with freshwater discharge? If not, it is not a relevant counterpoint to the earlier post.

The new study takes a detailed look at what happens when the balance is disrupted by greater quantities of freshwater flowing into the ocean, and the findings are a “major advance in AMOC stability science,”

I would append "from the Greenland Ice Sheet" to the title.

"However, because melting is causing the Greenland Ice Sheet to recede from the coasts of Greenland, where icebergs originate, its iceberg discharge should not persist long enough to cause major disruption of the Atlantic overturning circulation by itself"

The post title is very misleading.

This paper is specifically investigating if ice melt in Greenland, on its own, is strong enough to reverse the AOMC. The editor summarizes,

However, because melting is causing the Greenland Ice Sheet to recede from the coasts of Greenland, where icebergs originate, its iceberg discharge should not persist long enough to cause major disruption of the Atlantic overturning circulation by itself.

This leaves that possibility that Greenland ice melt + other factors are sufficient to cause AOMC reversal.
