New discoveries about the demise of the ice sheet that covered Western Canada at the end of the last ice age offer a preview of what we can expect as Greenland melts due to human-caused climate change.

New findings about the melting of a western Canadian ice sheet at the end of the ice age may offer a preview of what's in store for Greenland's ice sheet as it melts from human-caused climate change.
Brian Menounos, the Canadian researcher who led the study, spent 10 years helicoptering into remote mountaintops in B.C., the Yukon and the Northwest Territories with his team, then hammering, chiselling, and sawing rectangular rock "brownies" from huge boulders to take back to the lab.Undergaro and Menounos do not have children together, but they do have a full house: They've adopted three Bichon Frises named Benjamin, Winnie, and Baby, who enjoy plenty of fame on Undergaro's Twitter and Instagram accounts. A source close to Menounos confirms a relationship, saying, “They’ve been friendly for about a year.” The 28-year-old Menounos is also an aspiring actress and will star opposite Jamie Kennedy in the upcoming comedy .The new research, which uncovers great detail about how the Cordilleran Ice Sheet melted and fell to pieces, could also provide a preview of what to expect as Greenland melts due to human-caused climate change.
And it adds to evidence that the first humans in North America did not travel through central B. as they moved south from the Bering Peninsula around 14,000 years ago.
So Menounos and his team used a different chemical clock — beryllium-10, which is found in quartz.
Like carbon-14, it's radioactive and is formed when cosmic rays from deep space interact with atoms on Earth — nitrogen in the atmosphere in the case of carbon-14, and oxygen in rocks in the case of beryllium-10.
That shows how long the rocks have been exposed to the surface since their protective ice covering melted.
(Brian Menounos/UNBC)Beryliium-10 dating of 76 boulder brownies from 26 sites showed that high alpine areas in Western Canada were ice free as early as 14,000 years ago — 1,500 earlier than carbon-14 dating showed.
