Published research from the University of Vienna and the Swiss Federal Institute of Technology Zurich now establishes that human activity has pushed the planet’s rotation into territory unlike anything in 3.6 million years — and the engineers who keep Global Positioning System (GPS) working are already watching the numbers.
The finding, published in March 2026 in the Journal of Geophysical Research: Solid Earth, quantifies precisely what glaciologists and geodesists had been building toward: Earth’s days are currently lengthening at 1.33 milliseconds per century due to climate-driven ice melt and sea-level rise. That rate is, by the geological record stretching back to the Late Pliocene (a period in Earth’s history that lasted from about 5.33 million to 2.58 million years ago), without precedent.
A companion finding — from a separate 2023 study by Ki-Weon Seo and colleagues at Seoul National University — adds a second human fingerprint: agricultural groundwater extraction shifted Earth’s rotational pole roughly 80 centimeters eastward between 1993 and 2010 alone, making groundwater pumping the single largest climate-related driver of polar drift, according to that research.
Together, the two lines of work establish something that the prior generation of Earth scientists could not have stated with confidence: humanity has become, in the span of decades, a geological force potent enough to alter the mechanics of how the planet moves through space.

According to the context of the third paragraph, the phrase “adds a second human fingerprint” indicates that the study from Seoul National University
- Alternativa A: denies the idea that the human element contributes positively to climate change.
- Alternativa B: demonstrates the need for double-checking previous scientific evidence.
- Alternativa C: claims that until recently no human activity had a great impact on polar drift.
- Alternativa D, a correta: shows that a new layer of human authorship can be seen in Earth’s polar change.Resposta
- Alternativa E: monitors the evidence related to human groundwater pumping in early societies.
O que a questão pede: o que "adds a second human fingerprint" diz sobre o estudo de Seul.
Por que é a letra D: "fingerprint" é impressão digital, marca de autoria. O estudo acrescenta uma segunda marca humana: a extração de água subterrânea deslocou o polo de rotação. Ou seja, mostra mais uma camada de autoria humana na mudança do polo.
Por que as outras não:
- A O estudo não fala em contribuição positiva ao clima.
- B Não se trata de conferir evidências anteriores; é um achado novo.
- C O texto não afirma que antes nenhuma ação humana afetava o polo.
- E O período estudado é 1993 a 2010, não sociedades antigas.
