Antarctica's Missing Ice: A Gap the Size of France

A vast stretch of the Bellingshausen Sea has failed to freeze this winter, alarming scientists and threatening the food web that sustains Antarctic wildlife.

In June, the Bellingshausen Sea off Antarctica's west coast should be locked under thick winter ice. This year, satellites show it is almost entirely open water. The region is missing roughly 650,000 square kilometres of sea ice — an area comparable to France, and nearly ten times the size of Tasmania — when measured against the 1991–2020 average. On 10 June, total Antarctic sea ice stood at 11.

4 million square kilometres, more than a million short of the long-term mean for that date. Dr Will Hobbs, an Antarctic sea ice researcher at the University of Tasmania working with the Australian Antarctic Program Partnership, described the situation as "depressing." He noted that this is the third time in four years that winter ice in the region has collapsed to such low levels, and he did not expect a meaningful recovery. Scientists are actively investigating whether human-driven ocean warming is the primary driver, though shifts in ocean circulation are also considered a likely factor.

What is not in dispute is the trend: the ice is not returning as it once did. The ecological stakes are significant. Krill, the tiny crustaceans that underpin the Antarctic food web, typically shelter beneath winter sea ice, feeding on algae that grow on its underside.

Discuss
  • Why might the absence of winter sea ice be considered more alarming than summer ice loss?
  • How does the loss of sea ice in one region potentially affect global sea levels thousands of kilometres away?
  • Dr Hobbs said he does not expect the ice to return — do you think scientists should speak this definitively in public, and why?
  • What role do krill play in the Antarctic food web, and why does their survival depend on sea ice?
  • If you were advising a government on this data, what single policy would you prioritise, and what would you sacrifice to fund it?

Giant Planets Spin Faster Than Brown Dwarfs

Jupiter and Saturn each complete a full rotation in roughly ten hours — a fact that, until recently, had no clear parallel beyond our Solar System. Now, a team led by Northwestern University's CIERA has measured the spin rates of 32 distant gas giants and brown dwarfs using the Keck Planet Imager and Characterizer on Maunakea, Hawai'i. …
  • Does a planet's spin rate reveal more about its origin than its current size?

UK Chemical Safety Rules Face Legal Challenge

When Britain's parliament received new chemical regulations earlier this year, a single omission alarmed campaigners: all references to EU safety standards had quietly disappeared from the text. …
  • Should trade efficiency ever outweigh strict national chemical safety standards?

2GRAMMAR FOCUS
Gerunds and infinitives — complex patterns (stop to do vs stop doing)
Some verbs change meaning depending on whether they are followed by a gerund (-ing) or an infinitive (to + verb). For example, 'stop doing' means to cease an activity, while 'stop to do' means to pause in order to do something new.
to investigate · returning · investigating · to consider · sheltering · to point out · spinning
  1. Scientists have not stopped whether human-driven ocean warming is the primary cause of the sea ice collapse.
  2. Dr Phil Reid paused that the Pine Island and Thwaites glaciers lie just west of the Bellingshausen Sea.
  3. Without the frozen canopy, krill have stopped beneath the winter sea ice as they once did.
  4. Researchers stopped atmospheric factors alone once ocean circulation emerged as a likely driver.
  5. The floating ice shelves have effectively stopped as a brake on the glaciers' flow toward the ocean.
  6. The CIERA team continued whether a planet's formation history is encoded in its rotation speed.
  7. Giant gas planets have not stopped faster than the more massive brown dwarfs beside them, even when mass and age are accounted for.

4CRITICAL THINKING
The UK chemical safety case and the Antarctic ice data both involve governments being accused of downplaying risk — one through regulatory omission, the other through inaction on climate. To what extent do you think institutional reluctance to acknowledge danger is a matter of genuine scientific uncertainty, versus political or economic convenience?

6WRITING
The articles describe three separate scientific stories — vanishing ice, disputed chemical rules, and planetary spin rates — yet all three touch on the question of how formation shapes long-term outcomes. Write a short paragraph arguing either for or against the idea that origins determine destiny, drawing on at least two of the articles.
