Most of us know that human life has an enormous impact on Earth (and especially on the conditions that allow human life on this precious world) but it’s one thing to “know” and another to “see”.
Google has released a new service for the Earth Engine which offers a time-lapse of an area of Earth’s surface over the last 28 years, for example coal mining in Wyoming (those structures you see are about 10 km across).
Or Amazon Deforestation, Brazil. The image spans about 500 km.
Next time someone comes up “there is no scientific … global warming …”, you have something to show them.
And there is no scientist who doubts climate change. The only questions left are how much it will change, how much of that change is because of human greed and what the exact consequences will be.
