Visual FOG: John Tierney vs. Arthur Conan Doyle

The bubbling batches of lines below capture the first thousand words of Tierney's article Engineer the Climate? (top) and the Conan Doyle's Sherlock Holmes: A Scandal in Bohemia. Width of each line indicates sentence length; bumps show words of three or more syllables. Which is the more difficult read?

The Tierney article is more difficult, at least by Gunning Fog Index, which suggests 18 years of education for Tierney (40% of 45: the words in the flattened sentence equivalent) and 12 years for Conan Doyle (40% of 30).
