The incredible animations that reveal how much our planet has changed in just 28 YEARS.

From retreating glaciers to the appearance of man-made islands off the coast of Dubai: The incredible animations that reveal how much our planet has changed in just 28 YEARS

They are a breathtaking visualisation of just how quickly our planet is changing.

Google has released these astonishing images showing data collected from the Landsat satellite from 1982 until 2012.

They reveal everything from man's impact on the desert as Las Vegas expands to the retreat of glaciers in Columbia.

1. Glacier National Park has lost more than 80% of its glaciers

In Glacier National Park (GNP), MT some effects of global climate change are strikingly clear. Glacier recession is underway, and many glaciers have already disappeared. The retreat of these small alpine glaciers reflects changes in recent climate as glaciers respond to altered temperature and precipitation. It has been estimated that there were approximately 150 glaciers present in 1850, and most glaciers were still present in 1910 when the park was established. In 2010, we consider there to be only 25 glaciers larger than 25 acres remaining in GNP. A computer-based climate model predicts that some of the park’s largest glaciers will vanish by 2030 (Hall and Fagre, 2003). This is only one model prediction but, if true, then the park’s glaciers could disappear in the next several decades. However, glacier disappearance may occur even earlier, as many of the glaciers are retreating faster than their predicted rates.
