WASHINGTON, Feb. 18 - One of the perquisites of being president is the ability to have the author of a book you enjoyed pop into the White House for a chat.

Over the years, a number of writers have visited President Bush, including Natan Sharansky, Bernard Lewis and John Lewis Gaddis. And while the meetings are usually private, they rarely ruffle feathers.

Now, one has.

In his new book about Mr. Bush, "Rebel in Chief: Inside the Bold and Controversial Presidency of George W. Bush," Fred Barnes recalls a visit to the White House last year by Michael Crichton, whose 2004 best-selling novel, "State of Fear," suggests that global warming is an unproven theory and an overstated threat.

Mr. Barnes, who describes Mr. Bush as "a dissenter on the theory of global warming," writes that the president "avidly read" the novel and met the author after Karl Rove, his chief political adviser, arranged it. He says Mr. Bush and his guest "talked for an hour and were in near-total agreement."
