OMG - We're all gonna die - Global Warming

Anthropogenic Global Warming and Telegraph Cables -- why didn't anyone warn us. Oh. Wait. Nevermind. From the Museum of Hoaxes:

The Global Warming Hoax of 1874
This tale of global warming and a scientist's unsuccessful effort to stop it might sound like something out of today's headlines, but it isn't. The story appeared in newspapers over one hundred years ago, in 1874. It was presented to readers as a factual account of events, but in reality it was almost entirely fiction. It was a global-warming hoax!

The tale first surfaced in early February 1874, when the Kansas City Times printed the text of a letter it claimed to have received from one J.B. Legendre, who said that the letter had been sent to him, in turn, by an unnamed "American man of science" living in Florence, Italy. The correspondent detailed a discovery "of great and even agonizing importance to the human race" that he had learned of from other scientists in Italy.

The discovery was attributed to the Italian astronomer Giovanni Donati, who for many years, it was said, had been making daily measurements of the distance from the earth to the sun by means of an invention of his own design. In the course of making these measurements, Donati noticed that when the first transatlantic telegraph cable was laid, in 1858, the earth began to move closer to the sun. Initially the shift in orbit was quite gradual, but it quickly grew larger. And when another cable was subsequently laid connecting France to Massachusetts, the movement of the earth toward the sun accelerated rapidly.

Donati realized, to his terror, that the cables were acting like enormous electromagnets, pulling the earth into the sun. He calculated that if the earth's current trajectory continued unchecked, Europe would become tropical in 12 years, and the entire earth would be uninhabitable soon after. Finally the planet would plunge into the sun.

Donati warned the governments of the world, but the politicians were preoccupied with plans for war and paid him no heed. So he convinced several of his colleagues to join him in chartering a boat and breaking one of the cables. But the break was soon repaired, and the earth's descent into the sun continued.

Seeing there was no hope, and that the world was doomed, Donati's health gave way. He died of despair in December 1873.

Compare this to the hue and cry over a trace molecule essential to photosynthesis and start scratching your heads. Just about as plausible...
