NASA's State of Flux image collection features before and after pictures of more than 200 locations worldwide. The satellite images show the effects of climate change, natural disasters, and land use on places all over the globe. For some examples from the State of Flux collection take a look at the impacts of dam building in Brazil, drought along the Mississippi River, or volcanic activity in Iceland. You can browse for images by clicking placemarks on the State of Flux Google Map or by scrolling through the image gallery.
Applications for Education
If you're teaching lessons on climate change and human impact on the landscape, State of Flux could be a handy resource. Along with each set of images there is a caption about the area and the significance of the images. You could show some of the images to students without revealing the captions and ask them to propose ideas accounting for the causes of the changes they're seeing.
