The East Antarctic ice shelf cavities host cold water masses that limit melting, and only a few short-term observational studies exist on what drives warm water intrusions into these cavities. We analyse nine years of continuous oceanographic records from below Fimbulisen and relate them to oceanic and atmospheric forcing. On monthly time scales, warm inflow events are associated with weakened coastal easterlies reducing downwelling in front of the ice shelf. Since 2016, however, we observe sustained warming, with inflowing Warm Deep Water temperatures reaching above 0\u2009\u00b0C. This is concurrent with an increase in satellite-derived basal melt rates of 0.62\u2009m yr\n                    <jats:sup>\u22121<\/jats:sup>\n                    , which nearly doubles the basal mass loss at this relatively cold ice shelf cavity. We find that this transition is linked to a reduction in coastal sea ice cover through an increase in atmosphere\u2013ocean momentum transfer and to a strengthening of remote subpolar westerlies. These results imply that East Antarctic ice shelves may become more exposed to warmer waters with a projected increase of circum-Antarctic westerlies, increasing this region\u2019s relevance for sea level rise projections.\n                  <\/jats:p>","DOI":"10.1038\/s41561-023-01273-5","type":"journal-article","created":{"date-parts":[[2023,9,21]],"date-time":"2023-09-21T12:02:40Z","timestamp":1695297760000},"page":"877-885","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Warming beneath an East Antarctic ice shelf due to increased subpolar westerlies and reduced sea ice"],"prefix":"10.1038","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8410-0134","authenticated-orcid":false,"given":"Julius","family":"Lauber","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5538-2267","authenticated-orcid":false,"given":"Tore","family":"Hattermann","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6043-7920","authenticated-orcid":false,"given":"Laura","family":"de Steur","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3060-0317","authenticated-orcid":false,"given":"Elin","family":"Darelius","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6228-5732","authenticated-orcid":false,"given":"Matthis","family":"Auger","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6139-4088","authenticated-orcid":false,"given":"Ole Anders","family":"N\u00f8st","sequence":"additional","affiliation":[]},{"given":"Geir","family":"Moholdt","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2023,9,21]]},"reference":[{"key":"1273_CR1","doi-asserted-by":"crossref","first-page":"1720","DOI":"10.1126\/science.1125226","volume":"311","author":"R Bindschadler","year":"2006","unstructured":"Bindschadler, R.
