DENVER (AP) — A trove of ancient bones from gigantic animals discovered in the Colorado mountains is providing scientists with a fascinating look at what happened about 120,000 years ago when the Earth got as warm as it is today.
Evidence left behind by mastodons, mammoths, giant sloths and huge bison — along with insects, plants, pollen and other animals — offers a glimpse at how ancient animal adapted to climate change.
Among their findings: The warmer weather allowed forests to reach about 2,500 feet farther up the mountainside than today’s tree line, which is about 11,500 feet above sea level at the Snowmass site. Forests also may have been denser, and smaller trees and grasslands might have been more widespread amid drier conditions.
A team of 47 scientists has been studying material unearthed four years ago near Snowmass, a town just outside Aspen, when a bulldozer was enlarging a reservoir. The researchers published their first big batch of data in the journal Quaternary Research in November.
“The site is spectacular because it has a single continuous pile of sediment from the most recent interglacial period,” about 120,000 years ago, when conditions were similar to the present, said Ian Miller, chairman of the Earth
Butch Wilmore has a lot to be thankful for.
In a Thanksgiving video message from the International Space Station, the Murfreesboro, Tenn.-born astronaut expresses gratitude for everything from friends and family to freedom and food.
Wilmore gives thanks for the opportunity to fulfill his childhood dreams too–like hanging upside down like a bat in zero-gravity, which he demonstrates in the video at 3:45. Just check it out above.
He also takes a moment to show off the space station’s Thanksgiving dinner menu, which includes all the traditional holiday fare (with a few tweaks): irradiated smoked turkey, thermostabilized candied yams, and freeze-dried cornbread dressing. Yum…
As for breakfast?
“You don’t get no better than grits and butter,” Wilmore says in the video. “I can’t get enough of that up here, it’s good stuff.”
Two donuts of seething radiation that surround Earth, called the Van Allen radiation belts, have been found to contain a nearly impenetrable barrier that prevents the fastest, most energetic electrons from reaching Earth.
