It's like a pedestrian whodunnit that surprises no one, that no spoiler could spoil. We all knew — and have known — the party responsible for years, despite all the noise and denials.

A team of U.S.-led scientists announced on Monday that — surprise — man is responsible for global warming. As reported by Reuters, the scientists' findings, published by the journal Nature Climate Change, indicated that "human activities were raising the heat at the Earth’s surface," and that there certainty this was the case "had reached a 'five-sigma' level, a statistical gauge meaning there is only a one-in-a-million chance that the signal would appear if there was no warming."

This level of evidence, they said, amounted to a "gold standard of certainty," similar to the level of certainty applied in 2012, "to confirm the discovery of the Higgs boson subatomic particle."

The lead author on the study, Benjamin Santer of the Lawrence Livermore National Laboratory in the Bay Area, was blunt about the causes of climate change.

“The narrative out there that scientists don’t know the cause of climate change is wrong,” he told Reuters. “We do.”
