When Laura Larocca visited Denmark in 2019, the climate scientist sifted through thousands of old aerial photographs of Greenland’s icy coastline, which were rediscovered in a castle outside Copenhagen about 15 years ago.
Now housed in the Danish National Archives, the historical images inspired her and other researchers to reconstruct the territory’s glacial history and how it has changed amid a rapidly warming climate.
After digitizing thousands of archived paper images dating back to the 1930s, Larocca’s team combined them with satellite images of Greenland today to measure how much its frozen landscape has changed.
Larocca said she hopes this new visual-heavy study will draw attention to the rapidly melting territory and the threat it poses to the world’s coastlines as sea level rises.

Waste management and resource recovery remain essential to circular progress. The Department for Energy Security and Net Zero’s recent review identified strong potential for circular construction strategies and end‑of‑life reuse in construction to deliver quantifiable carbon savings. Yet challenges persist in the rollout of Simpler Recycling due to legacy property structures. Strengthening these back‑end systems ensures green building products re‑enter value chains, supporting both circular economy objectives and sustainable urban development. The collective impact across policy, design, education, and technology confirms that the carbon footprint of construction can be reduced dramatically when the sector treats sustainability as an integrated, measurable discipline rather than an optional ambition.
Whole Life Carbon is a platform for the entire construction industry—both in the UK and internationally. We track the latest publications, debates, and events related to whole life guidance and sustainability. If you have any enquiries or opinions to share, please do
