Time magazine in 1951 pointed to receding permafrost in Russia as proof that the planet was warming.

In 1952, the New York Times noted that the "trump card" of global warming "has been the melting glaciers."

There are many more examples of the media and scientists flip-flopping between warming and cooling scares.

Here is a headline from the New York Times reporting on fears of an approaching ice age: "Geologists Think the World May be Frozen Up Again."

That sentence appeared over 100 years ago in the February 24, 1895 edition of the New York Times.

Let me repeat. 1895, not 1995.

A front-page article in the October 7, 1912 New York Times, just a few months after the Titanic struck an iceberg and sank, declared that a prominent professor "Warns Us of an Encroaching Ice Age."

The very same day in 1912, the Los Angeles Times ran an article warning that the "Human race will have to fight for its existence against cold." An August 10, 1923 Washington Post article declared: "Ice Age Coming Here."
