A Washington, D.C., resident recently came across a 1922 article that revealed early signs of climate change.
John Lockwood found a 1922 article in The Washington Post when he was conducting research at the Library of Congress. The article's headline read: "Arctic Ocean Getting Warm; Seals Vanish and Icebergs Melt," according to a report in the Washington Times.
The article reports "great masses of ice have now been replaced by moraines of earth and stones," and "at many points well-known glaciers have entirely disappeared."
Lockwood said he's discovered other articles from the 1920s and 1930s on the same subject.
"I had read of the just-released NASA estimates, that four of the 10 hottest years in the U.S. were actually in the 1930s, with 1934 the hottest of all," Lockwood said.
