Our planet is constantly changing, but we are too small to see how it looks from a bigger distance. We know that global warming is one of the reasons the world looks different every day. And we humans are to be blamed for that. The change is not significant on a daily basis. We can only realize the devastating effect of climate change and global warming if we compare the pictures of the same places over time.
NASA has already done that and below you can see how we have changed the appearance of the landscape over the years. The time difference between these images ranges from five to 100 years. The difference is dramatic.
