The impact of climate change on the environment is not always easy to see. Now, with NASA’s Images of Change iPad application, users can get an interactive before-and-after view of the changes.

The App is showing two images next to each other, showing the same region, that have been affected by the global climate change, disasters, global warming or a human activity.

NASA shows to the end users, using space based observation systems, the changes that are occurring on the planet and offer an even broader collection of images on their website. Making information of this sort accessible to citizens is a key aspect of the new US-Government policy on Climate Change.
