Rotten eggs or rotten headlines?
Is our death from a hydrogen sulfide event inevitable in climate warming? (2005)
Rotten egg sky? Crowd splits between doom, acid oceans, and Betteridge’s snark
TLDR: Scientists say past warming could trigger low-oxygen oceans and toxic hydrogen sulfide, but the study adds that today’s seas aren’t primed for that. Commenters battle: doomers warn mass die-off or acid oceans, skeptics invoke Betteridge’s law and headline misrepresentation. It’s a fight over risk, not a forecast.
An old-but-spicy study resurfaced: ancient Siberian volcanoes may have warmed the planet, slowed ocean oxygen, and let bacteria belch hydrogen sulfide—the rotten-egg gas—triggering the Permian die-off. Cue the comments throwing elbows. Doom-posters say this is a real failure mode of climate change, while others cry sensational headline. One group points to the science’s big caveat: the researcher notes today’s oceans don’t have enough organic gunk to go fully oxygen-free, so the “inevitable death” phrasing is a reach.
The hottest counter-take? Acidification. A top reply warns carbon dioxide makes the sea so acidic plankton shells dissolve, and if the base of the food chain breaks, “maybe no more fish.” Skeptics flex Betteridge’s law: any headline that’s a question is probably answered “No.” There’s even some pedantry: “(2010) should be in the title?” because internet timestamp drama never dies.
Meanwhile, the crowd trades scary trivia—humans can smell hydrogen sulfide at insanely low levels, and the Black Sea hides toxic depths—while another camp insists the headline misrepresents the paper’s nuance. It’s a perfect storm of rotten eggs vs. rotten headlines, doomers vs. debunkers, and a history lesson on the Permian extinction that’s suddenly very now.
Key Points
- •Siberian Trap eruptions coincided with the end-Permian extinction and likely triggered CO2-induced warming.
- •Warming reduced ocean oxygen solubility and slowed deep circulation, promoting widespread anoxia.
- •Anoxic conditions enabled sulfate-reducing bacteria to produce toxic hydrogen sulfide, lethal to aerobic life.
- •Hydrogen sulfide can destroy ozone; fossil spore deformities suggest increased UV exposure at the time.
- •The proposed H2S-rich atmosphere and methane persistence better explain the mass extinction than CO2 alone.
