when did the book polar express come out
The Polar Express The Polar Express is a children's book written and illustrated by Chris Van Allsburg and published by Houghton Mifflin in 1985. The book is now widely considered to be a classic Christmas story for young children although the point has been challenged.[a] It was praised for its detailed illustrations and calm, relaxing storyline. For the work Van Allsburg won the annual Caldecott Medal for illustration of an American children's picture book in 1986, his second.[1][2]
Polar bear There are 19 generally recognized, discrete subpopulations, though polar bears are thought to exist only in low densities in the area of the Arctic Basin.[37][39] The subpopulations display seasonal fidelity to particular areas, but DNA studies show that they are not reproductively isolated.[34] The thirteen North American subpopulations range from the Beaufort Sea south to Hudson Bay and east to Baffin Bay in western Greenland and account for about 54% of the global population.[40]
