This summer at the Denver Museum of Nature and Science, we saw the visually magnificent IMAX film "National Park Adventure," sponsored by Subaru and Expedia Travel. A substantial segment of the film focused on Glacier/Waterton Lakes National Park, where the glaciers are retreating rapidly.

When I visited the park a few years ago, the rangers tried to make sure that every visitor understood that this melting is a strong indicator of climate change. But the film made absolutely no mention of the fact the glaciers in Glacier are rapidly melting, and DMNS did not say a word about it in connection with the film.

Was this irresponsible omission due to the sponsorship of the film by an automobile company and a travel company? Or to the funding DMNS receives from coal and oil industries?

I wonder what they will do to make up for not even mentioning the glaciers' melting at such a teachable moment! If they do nothing, many of us will conclude that DMNS is too afraid of the oil and coal industries to be scientific in their selection of the information they present to visitors.
