(Global Citizen) – Climate change rarely transforms an environment overnight. By the time ice shelves disappear, ocean waves creep onto main streets, and forests shrivel, the forces of climate change have been at work for decades.
Fortunately, NASA is tracking these environmental changes with satellites so that the public knows the full scale of transformations taking place. From one month to the next, an environmental change might seem slight, but when you zoom out to the level of years and decades, the combined shifts paint a devastating portrait. Of course, there are also sudden, dramatic events like flash floods that overwhelm a region overnight. But these, too, are the result of weather patterns that have morphed over decades.
Here are seven transformations that NASA has captured.
