Climate crisis is making days longer, study finds
    Melting of ice is slowing planet’s rotation and could disrupt internet traffic, financial transactions and GPS. The climate crisis is causing the length of each day to get longer, analysis shows, as the mass melting of polar ice reshapes the planet.
    The phenomenon is a striking demonstration of how humanity’s actions are transforming the Earth, scientists said, rivalling natural processes that have existed for billions of years. The change in the length of the day is on the scale of milliseconds but this is enough to potentially disrupt internet traffic, financial transactions and GPS navigation, all of which rely on precise timekeeping.
    The length of the Earth’s day has been steadily increasing over geological time due to the gravitational drag of the moon on the planet’s oceans and land. However, the melting of the Greenland and Antarctic ice sheets due to human-caused global heating has been redistributing water stored at high latitudes into the world’s oceans, leading to more water in the seas nearer the equator. This makes the Earth more oblate – or fatter – slowing the rotation of the planet and lengthening the day still further.
   The planetary impact of humanity was also demonstrated recently by research that showed the redistribution of water had caused the Earth’s axis of rotation – the north and south poles – to move. Other work has revealed that humanity’s carbon emissions are shrinking the stratosphere.
    “We can see our impact as humans on the whole Earth system, not just locally, like the rise in temperature, but really fundamentally, altering how it moves in space and rotates,” said Prof Benedikt Soja of ETH Zurich in Switzerland. “Due to our carbon emissions, we have done this in just 100 or 200 years. Whereas the governing processes previously had been going on for billions of years, and that is striking.”

Questão presente nas seguintes provas
A validade dos argumentos é um conceito importante em lógica e matemática, relacionando-se estritamente com a forma dos argumentos e a implicação lógica entre premissas e conclusão, sem considerar o conteúdo específico ou a verdade das premissas. Analise as afirmativas sobre a validade dos argumentos:

I - Um argumento é válido se a verdade das premissas garante a verdade da conclusão.
II - Um argumento pode ser válido mesmo que suas premissas e conclusão sejam todas falsas.
III - A validade de um argumento é determinada testando todas as possíveis combinações de verdade das premissas e da conclusão em uma tabela-verdade.
IV - Um argumento é válido apenas se suas premissas são verdadeiras.

Assinale a alternativa correta:
