It’s not easy for 505 million years of biological and evolutionary history to sneak up on you.

Posted by Allen Macartney in Expeditions on Thursday, July 26, 2012

Last week I got to spend a day out with paleontologist Grant Zazula and his two assistants. We spent about 10 hours walking over a creek bed in a gold mine that has yielded extraordinary fossil remains. This is a fully working gold mine, and the owner lets paleontologists explore freely.

Since trees only grow sparsely and to a few feet high on the tundra, it was definitely out of place.

"I knew that was a rare thing and I was interested in seeing it," Barker tells CG, "I knew there was a possibility of forests up there in the past. When they told me they found ...

Letters About our Climate Future

Posted by Graham Lanktree on Friday, November 12, 2010

Climate Futures. October 2010.

Our climate futures issue in October struck a chord with many Canadians. Some thought we didn't do enough to warn about the dangers of a warming world and urge action. Others thought that we did too much and wondered why we would cover the topic at all.

Below we've collected together a mixed-bag of the mail we received to show the spectrum of opinions that arrived at our door.

We would like to hear more and welcome you to add your voice. What do you think ...
