Tiny Matters How glaciers safeguard Earth’s future and hold clues to our ancient past
The reason many of us hear about glaciers has to do with sea level rise — which makes sense! If all of the glaciers on Earth melted, sea levels are predicted to increase by about 230 feet (70 meters), which would flood coastal areas, envelope a number of islands, and seriously impact human infrastructure, including our current water resources. But glaciers do more than safeguard Earth’s future — buried within them is our ancient past. In January of this year, a team of scientists drilled nearly 2 miles down into an Antarctic glacier. The 1.7 mile long cylinder of ice they pulled up, called an ice core, holds the equivalent of 1.2 million years of climate history. In this episode of Tiny Matters, we talk about what glaciers mean to us today, their importance for the future of our planet, and what they tell us about Earth’s ancient past.
