NASA has published a film of Earth’s seasons showing how the climate has changed in the past twenty years. As they say, we only have one planet, and it’s a delicate place.
The data visualization, released this week, shows Earth’s fluctuations as seen from space.
The polar ice caps and snow cover are shown ebbing and flowing with the seasons. The varying ocean shades of blue, green, red and purple depict the abundance – or lack – of undersea life.
“It’s like watching the Earth breathe. It’s really remarkable,” said Nasa oceanographer Jeremy Werdell, who took part in the project.
