New iPad app from NASA shows before and after photos of Earth

Since climate change happens gradually, its effects can only be seen in retrospect. In order to help with this, NASA has released a new iPad app called Images of Changes that shows before and after photos of Earth and how climate change has changed it over the years.

The effects of climate change, and those of our own human activities on the Earth, can be hard to relate to if they aren’t in our own backyard. But as they say, seeing is believing, and a new iPad app from NASA brings those changes to life.
