🗞️ Driving the news: A study suggests the world may experience its first "negative leap second" around 2029 due to the Earth rotating faster, an effect partly offset by climate change
• Without global warming, this adjustment might have occurred in 2026

🔭 The context: Earth's rotation has sped up because of its hot liquid core's dynamics and the melting of polar ice due to human-driven climate change, which has slightly slowed this acceleration
• Timekeeping experts find themselves navigating uncharted territory, as the potential need for a negative leap second emerges.

🌍 Why it matters for the planet: This development highlights the intricate ways in which climate change impacts our world, extending even to the realm of global timekeeping
• The slowing effect of melting ice on Earth's rotation serves as another stark reminder of our changing planet

⏭️ What's next: The discussion on implementing a negative leap second underscores broader challenges in global timekeeping amidst technological advancements and environmental changes 
• The decision will impact various sectors, including technology and astronomy

💬 One quote: "This is an unprecedented situation and a big deal," said Duncan Agnew, study lead author and geophysicist at the Scripps Institution of Oceanography

📈 One stat: Between 1972 and 2016, 27 leap seconds were added to account for Earth's slowing rotation, but now we face the possibility of subtracting time.
