Letter: Earth is always changing

Recently, I was perusing World Book Encyclopedia in search of information on an author, when I came upon an entry for Donald Baxter MacMillan. He was a later explorer of Greenland and the Canadian Arctic and received the Special Congressional Medal for surveying and charting them for the U.S. Army during World War II. He made 31 trips to the arctic during his lifetime and wrote several books about his experiences.

He used radio communications extensively and airplanes and made many special aerial photographs. It says he found coal deposits nine degrees from the North Pole and that they “contained remains of 36 kinds of trees.”

Obviously, the arctic was much warmer at one time than it is now. Is this information problematic for the global warming crowd?
