The heating is uneven, because of night and day, because different surfaces (such as rocks and
trees) absorb and reflect sunlight in different amounts, and because sunlight hits the equator more directly
than the
poles.
That all changed, however, when the Haida Nation of British Columbia's Queen Charlotte Islands — known across Canada for its colourful totem
poles carved from red cedar — took issue with a
tree - farming licence the provincial government had issued to lumber - giant Weyerhaeuser Co., allowing it to log on land claimed by the Haida more
than a century earlier.
