"The Memory of Darkness, Light, and Ice" won the 2026 national Emmy for Outstanding Science and Technology Documentary. The film focuses on research at the University at Buffalo studying ancient soil drilled from beneath the Greenland Ice Sheet.
Why it matters
The sediment indicates the ice sheet was much smaller 400,000 years ago, when global temperatures were similar to today's. That comparison offers a reference point for how Greenland's ice may respond to current warming.
A sediment sample containing plant remains from 400,000 years ago shows the Greenland Ice Sheet sat more than 100 kilometers behind its present position. Researchers have not yet determined how quickly today's melt compares with that earlier retreat.
The players
University at Buffalo
A public research university in New York whose researchers analyzed the Greenland sediment sample.
The details
U.S. Army operatives drilled beneath a Cold War-era military camp in Greenland, aiming to place nuclear missiles under the ice, and instead unearthed the soil sample. Researchers at the University at Buffalo studied the sediment, which shows "sustained but moderate warmth" caused the ice sheet's reduced coverage.
Timeline
400,000 years ago: Ice sheet was smaller and plant remains were deposited under Greenland.
1950 to 2000: Baseline period for Arctic temperature projections.
2024: A study found the Greenland Ice Sheet lost more ice than previously believed.
2025: The documentary was released.
2026: The film won the national Emmy for Outstanding Science and Technology Documentary.
Roadmap
A 2024 study found the Greenland Ice Sheet lost more ice than previously believed, and the new sediment evidence extends that picture back 400,000 years. Together they show the ice sheet has previously retreated well behind its current edge under temperatures comparable to today's.
Residents concerned about sea level exposure should track official local flood-risk maps for coastal areas. The extraction does not include specific protective steps for the public.
The takeaway
Ancient sediment can serve as a natural record of how the ice sheet responded to past warmth. Readers tracking climate change can use that record to better understand how quickly the ice may shift under current conditions.
