Dear MEL Topic Readers,
Google Earth's new Timelapse feature shows chilling effect of climate change
One of the most evident ways to show the changes over time is before-after images. For example, the Aral Sea, which lies between Kazakhstan in the north and Uzbekistan in the south, had been shrinking for the last half-century until 2010 and it is mostly dried out. It was mainly a result of the increased salinity as well as the testing of weapons and other fertilizer run-offs. Receding glaciers and melting ice sheets are typical examples of global warming. Urbanization and irrigation have caused deforestation and desertification in many places. Our only planet, at least for the time being, has been changed by human activities ever since the first industrial revolution took place. Especially since the late 20th century when population and economy have both been growing at much a faster pace than ever before, changes in the land, waters, and air are drastic. Google, having worked with NASA and other agencies and institutes, create a new eye-opening feature called Timelapse that shows satellite images of continuous changes of the Earth between 1984 and 2020. It shows clearly how much glaciers have receded, deserts have been irrigated or urbanized, or forests have been cultivated. Seeing is believing. Images might help people motivate to take action more and faster.
Enjoy seeing the before-after images and checking Timelapse to learn about the changes of our mother planet.
