Beautiful new aerial images of Mont Blanc reveal the extent of ice loss over time within the Alps.

A century in the past, the Swiss pilot and photographer Walter Mittelholzer flew over Mont Blanc in a biplane to {photograph} the alpine panorama. In August, researchers from the College of Dundee in Scotland re-created his images to indicate how the mountains have modified over time.

Kieran Baxter and Alice Watterson from the 3DVisLab at Duncan of Jordanstone School of Artwork and Design, a part of the College of Dundee in Scotland, flew over the Mont Blanc massif to repeat three of Mittelholzer’s iconic images of the glaciers.

Scientists used a course of known as “monoplotting” to seek out the unique digital camera place in airspace; then they used the peaks and spires of the alpine panorama as anchor factors to seek out the geolocation of the historic photographs.

The brand new images of the Argentiere, Mont Blanc Bossons and Mer de Glace glaciers present the massive scale of ice loss within the area.

Dr Baxter, geared up with waypoints from the digital evaluation and a number of GPS units, hung from the aspect of the helicopter because it hovered just under the summit of Mont Blanc to seize the images.

“The size of the ice loss was instantly evident as we reached altitude however it was solely by evaluating the photographs side-by-side that the final 100 years of change have been made seen. It was each a wide ranging and heartbreaking expertise, significantly understanding that the soften has accelerated massively in the previous couple of many years,” stated Kieran Baxter, of the College of Dundee, in a press release.

“Until we drastically scale back our dependence on fossil fuels, there can be little ice left to {photograph} in one other hundred years,” Baxter warned.
