A Canadian astronaut on a six-month stay aboard the international space station said on Sunday it looks like Earth’s ice caps have melted a bit since he was last in orbit 12 years ago. Bob Thirsk said that there is a “very thin veil of atmosphere around the Earth that keeps us alive … Most of the time when I look out the window I’m in awe. But there are some effects of the human destruction of the Earth as well,” Reuters quoted him as saying.
“This is probably just a perception, but I just have the feeling that the glaciers are melting, the snow capping the mountains is less than it was 12 years ago when I saw it last time,” Thrisk was quoted as saying. “That saddens me a little bit.”
