Coleman started his career in 1953 at
WCIA in
Champaign, Illinois, doing the early evening weather forecast and a local bandstand show called
At The Hop while he was a student at
University of Illinois at Urbana–Champaign. In 1972, Coleman and his stage crew craftsmen at WLS-TV created the first
chroma key weather map ever in use. He stayed seven years with the program, which was anchored by
David Hartman and
Joan Lunden. in what Coleman fondly calls "his retirement job.". Coleman obtained professional membership status in the American Meteorological Society and was named AMS Broadcast Meteorologist of the Year in 1983. Coleman said that after ten years of attending AMS National Meetings and studying the papers published in the organization's journal, the AMS was driven by political, not scientific, agendas and withdrew. == Views on global warming ==
