Beginning Tuesday and running until the end of the Republican National Convention in July, the most widely circulated print newspaper in the United States will run a series of ads calling out its own bias against climate change.

The Wall Street Journal’s editorial pages may be the beating heart of climate-change skepticism, but the newspaper apparently was willing to entertain an alternative view — for a price. The leading business newspaper is letting an obscure environmental group challenge the Journal editorial page’s orthodoxy on the issue, although it will cost the group thousands of extra dollars to run its kickoff ad on the page.

The editorial page of The Wall Street Journal is notorious for its climate denial. It frequently publishes opinion pieces like this one comparing climate activism to the Inquisition, or this one arguing that the evidence of climate change is based on faulty data. But the page is willing to print other views — for a price.
