Ever since Frank put together the "Blue Marble" overlay, it's been one of my favorite overlays for Google Earth. I leave it on almost all the time, because it creates such a nice view of the earth when seen from very high altitudes. Of course, the Blue Marble only shows how the Earth looks right now. What if you could see the past (and future) of our planet with a similar overlay? That's what the folks at ZHAW have put together, and it's quite impressive. They've created a few animations that show changes in the Earth's glaciers, vegetation and sea levels throughout the years. Here's a look at their "Blue Marble 3000" animation, which begins 21,000 years ago, and ends in the year 3000.
They also have a version of it that starts with present-day Earth and goes until the year 10,000:
In addition to the views, they've created overlays that you can use inside of Google Earth. You can find more info about Blue Marble 3000 here, and Blue Marble 10,000 here.
They collected the data from a variety of sources, and certainly had to make some estimations for future ice and shorelines. Still, it's an interesting look at where we've been and where we might be heading.
Extreme makeover: are humans reshaping Earth? If alien geologists were to visit our planet 10 million years from now, would they discern a distinct human fingerprint in Earth's accumulating layers of rock and sediment?...
Oregon's rare white buffalo herd grows with three new calves
(Right) Cynthia Hart-Button figures the birth of so many white buffalo "means there are earth changes coming." This is among three white buffalo calves born over the Mother's Day weekend at Hart-Button's sanctuary near Bend.
What may be the world's biggest herd of white buffalo has just gotten bigger. Three white bison calves were born on a 288-acre sanctuary near Bend over the Mother's Day weekend, bringing the number of white bison to 14...
