Global Climate Change in NASA Photos: Before and After

The increase in average temperatures and ocean levels around the world is known as global warming, although it would be more correct to talk about global climate change. These impressive images from the US National Aerospace Agency (NASA) show how much the landscape has changed in some regions of the planet in just a few years.
