Eye in the Sky Monitors Change

Thursday 19th July 2012

As a reminder of one of the reasons we are all interested in energy saving is this image from NASA. It’s from their Aqua satellite and shows a giant iceberg breaking off the Peterman Glacier on the northwestern coast of Greenland - it is reportedly twice the size of Manhattan.

We usually consider energy saving technology in these posts, gadgets and devices that directly affect energy use, including energy monitoring and management. Satellite technology allows us to monitor the effects of climate change, and energy use globally.

This image comes from a reasonably inaccessible location, yet it is clear, it was also published within hours of being taken, and it is one of a sequence of equally clear images showing the progress of this lump of ice.

Having a global view of the effects of climate change, and hopefully in the future the results of our actions to overcome it, enables us all to see the ‘bigger picture’ - no pun intended - and see the results of our energy saving efforts - it is a monitor.

So what does this satellite image show us? This is the calving of a new super iceberg, showing it drifting downstream on July 16–17, although smaller than a predecessor two years ago, this whole sequence is raising concerns.

The glacier has receded drastically. Data for the glacier goes back 150 years and in that time it has never been shorter. Some experts are calling the changes to the glacier ‘dramatic’ and ‘disturbing’.

Individually we can do a little, and we can benefit from the effects of actions locally, but together we can do a lot and affect the whole world. The power of satellite technology helps us to see what we are doing as a planet.
