The melting of polar ice due to climate change is affecting global timekeeping, according to a recent scientific study. The loss of ice is causing a shift in the Earth's axis, which in turn impacts the planet's rotation. This has led to changes in the length of a day, affecting the accuracy of timekeeping systems.
The composition beneath the polar ice sheets differs depending on whether it's the North or South Pole. The Arctic ice is relatively thin, with the waters of the Arctic Ocean beneath it. In contrast, Antarctica is an actual continent, with an ancient rocky landmass hidden beneath its thick ice. Researchers have explored the seafloor beneath the Arctic ice and discovered a muddy surface covered in algae, suggesting the presence of life in unexpected places. This knowledge expands our understanding of where life can thrive and encourages the search for signs of life in icy environments on other planets.
Polar ice is melting, and it is the primary contributor to sea level rise. NASA uses satellite lasers to monitor the thickness of ice in Antarctica and Greenland, identifying where the ice sheets are thinning and losing mass most rapidly into the ocean. The melting process is not only about the melting itself, but also about the balance between snowfall and ice melt. Scientists study the relationship between ice sheets and sea levels to better understand our changing planet.
