1000’s of pictures have been taken, usually of overlapping areas, and the staff then used software program to rework these right into a hi-res 3D mannequin of the terrain.

Dr Baxter stated this meant that pictures wanting straight down on to the panorama may then be re-framed to point out the terrain from completely different angles.

However the issue of glacier loss attributable to local weather change is a worldwide concern. The most recent Intergovernmental Panel on Local weather Change (IPCC) report warned that smaller glaciers in Europe, Africa, the Andes and Indonesia have been projected to lose greater than 80% of their present ice mass by 2100 if carbon emissions remained excessive.

The ensuing rise in sea stage may have enormous penalties for hundreds of thousands of individuals, the UN panel warned.
