Seeing the Changes

Thursday 5th December 2013

We are all starting to realise the impact of climate change with ever dramatic weather events hitting almost everyone to a greater or lesser degree. But do we really wish to wait for the consequences to hit us fully in the face to accept that we need to combat climate change.

Although we have been getting a pretty good slapping over the last 12 months or so, NASA has launched an app that brings home how we should have been taking more notice beforehand of the effects of human activities and climate change.

Hence, seeing is believing with the new iPad app from Nasa as it shows pictorially the changes to the earth either over a short period and sometimes, most dramatically, over decades.

The Image of Change app, which is free to download, features pairs of images of many locations around the globe - an earlier image displaying either from space or on the ground, what, for example a mountain range and glacier looked like, maybe in the 1940s, compared to what it looked like in 2005 to even this year.

The app is available to download but you can also go to NASA’s Global Climate Change website to compare the 'before and after' pictures. On the app and the website you can either look at pairs of pictures, side by side, to see most dramatically the changes that have happened, or look at each one individually.

Side by side you can choose different ways of analysing the images, all again to highlight the change through human behaviour or climatic events and effects. You can choose a ‘curtain’ view which provides a swipe across the image so you can see the change, a toggle view to switch between the images as one overlays the other, or a straight side by side of the before and after.

The images will be constantly updated - providing a resource for all those interested in combating climate change through improving energy efficiency with a resource to underline the importance of reducing greenhouse gas emissions.
