What this story says

  • The Thwaites Glacier in West Antarctica is melting faster than previously projected, a new study shows.
  • This accelerated melting could double the glacier's contribution to global sea level rise, according to researchers.
  • The glacier's collapse could eventually raise sea levels by more than two feet, potentially up to 10 feet if it holds back the wider Antarctic ice sheet.
  • Scientists from the University of California, Irvine, and NASA's Jet Propulsion Laboratory conducted the research, published in Nature Communications.

The Thwaites Glacier in West Antarctica is melting at a faster rate than previously projected, according to new research. Scientists involved in the study warn that this accelerated melting could double the glacier's contribution to global sea level rise. The findings were published in the journal Nature Communications.

The research, conducted by glaciologists from the University of California, Irvine, and NASA's Jet Propulsion Laboratory, used a new ice sheet model. This model better reflects processes occurring at the glacier's grounding line, the point where the ice lifts off the seabed. The study indicates that seawater flushing in and out with the tides, a process known as tidal pumping, allows warm ocean water to penetrate deep beneath the ice, causing vigorous melting. This mechanism is accelerating the retreat of the glacier.

Potential Sea Level Rise

The Thwaites Glacier, sometimes referred to as the 'Doomsday Glacier', currently contributes about 4% to global sea level rise. If it were to collapse, it holds enough water to raise sea levels by more than two feet. Its role as a barrier to the larger Antarctic ice sheet means its collapse could ultimately lead to a rise of around 10 feet. The new study suggests that by 2100, Thwaites could contribute up to 1.2 inches to sea level rise, twice previous estimates, even without further global warming.

What the coverage left out

None of the left, centre, or right-rated reports printed below mention the specific projection of a 60% chance that the glacier will be unpinned from a large ridge called the Mouginot Ridge by the end of the century, after which it is likely to retreat quickly. None of the right-rated reports mention the specific figure of 1.2 inches of sea level rise by 2100 as a potential outcome of the new model, a detail present in centre and left-rated reports.

How each side covered it

Our own reading of the reporting listed below, written from the outlets’ articles rather than quoted from them. The reasoning is set out on our methodology page.

Left

5 rated outlets

  • Left-rated reports highlighted the accelerated melting and the potential for doubled sea level rise. Several reports used the term 'Doomsday Glacier' or 'Apocalypse Glacier' in their headlines. Il Fatto Quotidiano noted the glacier's size, comparing it to Florida, and its potential to inundate coastal communities from Miami to Manila. IBTimes UK reported that the glacier could contribute twice as much to sea-level rise by 2100, citing the importance of seawater movement beneath the ice. Novinky.cz stated the glacier could raise ocean levels more than expected and lose important natural supports. Gizmodo focused on ocean water seeping under the glacier and the doubling of its sea-level threat. TVN24.pl reported that the glacier is losing ice faster than previously thought, with processes between the floating and seabed-resting parts being responsible.

  • Centre-rated reports focused on the 'aggressive' melting and the increased impact on sea level rise. CTV News reported that the planet's widest glacier is melting 'more aggressively' than projected, with impacts on sea level rise potentially doubling current estimates. TF1 INFO alerted that the 'Glacier of the End of the World' melts 'faster' than expected. Euronews reported that the Doomsday Glacier is 'committed' to melting and questioned whether it can be stopped, noting its collapse would contribute an estimated 65cm to global sea level rise. KCRA 3, WCVB, WLWT, WMUR, and Koco News5 all used similar headlines stating scientists knew the glacier was melting but did not realise how 'aggressively'. WLWT and WLKY also used this phrasing.

  • Right-rated reports highlighted the increased threat of sea level rise and the glacier's size. Globo's headline stated the melting of the 'Final Judgement Glaze' could have an impact twice as great as imagined. Times of India reported that the Britain-sized Doomsday Glacier is melting faster than feared, with warm ocean waters intruding beneath its surface. GB News stated the 'Doomsday Glacier' the size of Great Britain threatens UK coastlines. Tippinsights reported that a new study warns the Doomsday Glacier could raise sea levels twice as much as estimated, contributing up to 30 millimetres by 2100. TV Azteca noted the Antarctic monster accelerated its thaw by losing about 50 billion tons of ice a year. The News reported that the Doomsday Glacier melts more aggressively than thought.

Questions about this coverage

How did the left and right cover Thwaites Glacier Melting Faster Than Expected, Scientists Warn?
Of the 59 outlets on this story carrying a published leaning rating, 9% are rated left, 79% are rated centre, 12% are rated right. Those percentages are shares of the rated outlets, not of every outlet that ran it, which was 82. The sections above set out what each side emphasised, in its own terms.
Is Thwaites Glacier Melting Faster Than Expected, Scientists Warn left or right?
The story itself is neither. What can be counted is who has covered it, and 79% of the 59 rated outlets on it are rated centre — so far this is a story carried mostly by the centre. Coverage is still arriving and that can change, which is why the figure is dated rather than fixed.
Is the coverage of Thwaites Glacier Melting Faster Than Expected, Scientists Warn biased?
Thwaites Glacier Melting Faster Than Expected, Scientists Warn is one event reported by 82 outlets, and this page does not rate the story as biased or unbiased. What it publishes is the spread: which outlets ran it, where named rating organisations place each of them on the spectrum, and what each side chose to lead with. A leaning rating describes an outlet's record over time, not this article, and the two should not be run together.
Which outlets covered Thwaites Glacier Melting Faster Than Expected, Scientists Warn?
82 that we know of, every one of them listed further up this page with a link to its own report and to what we hold on the publisher. Nothing here is a summary of somebody else's summary: the outlets are named so the original reporting can be read.
Why is the Thwaites Glacier called the 'Doomsday Glacier'?
The Thwaites Glacier is nicknamed the 'Doomsday Glacier' or 'Apocalypse Glacier' due to the catastrophic consequences its collapse could trigger for global sea levels and coastal communities worldwide. Its potential to raise sea levels significantly makes it a major concern for climate scientists.
How much could the Thwaites Glacier contribute to sea level rise?
The Thwaites Glacier currently contributes about 4% to global sea level rise. If it were to collapse entirely, it could raise sea levels by more than two feet. Furthermore, because it acts as a barrier to the larger Antarctic ice sheet, its collapse could ultimately lead to a rise of around 10 feet.
What is new about the latest research on the Thwaites Glacier?
New research published in Nature Communications indicates that the Thwaites Glacier is melting faster than previously projected. A new ice sheet model used by scientists suggests that the glacier's contribution to sea level rise by 2100 could be double previous estimates, potentially reaching 1.2 inches even without further global warming.
