The latest Bloomberg Businessweek devotes its first two substantive pages — the “Opening Remarks” feature — to Charles Kenny’s musings about “the inability of the world’s leaders to reach a deal on climate change,” which he describes as “the greatest global challenge of the new century.”

Given the topic’s obvious importance, it’s curious that Mr. Kenny makes no reference in his 1,300-word piece to the word “Climategate” or to its latest iteration, Climategate 2.0.
