Hot planet, hotter comments
2025 Was Another Exceptionally Hot Year
Records melt while the comments combust: conspiracy, denial, and memes collide
TLDR: 2025 is the second-hottest year ever, with scientists pointing to a volcano, El Niño, more sun, and less ship pollution as partial causes. The comments explode into conspiracy theories, DIY skeptics, and energy fights, showing a chaotic mix of worry, denial, and urgency over what comes next.
It’s official: 2025 is the second-hottest year ever, only beaten by 2024, with the last three years all blasting past the 1.5°C “do-not-cross” line set by global agreements. Scientists are scratching their heads, pointing at a mix of culprits—an underwater volcano, a sunnier sun, El Niño, and a big drop in sunlight-blocking pollution from ships and coal. Climate researcher Zeke Hausfather argues these four together could explain the surge, but the big suspense: is this a blip or the new normal?
The comments? Flaming. One user wonders if secret geoengineering is happening behind the scenes, asking if we’d even notice beyond “anomalous heating.” Another shrugs that record-breaking weather is already routine, while josefritzishere drops the line of the week: “We are failing an open book test.” Then comes the plot twist—egberts1 claims a DIY analysis shows US temps “largely flat” after excluding post-1973 stations, prompting an instant fact-check pile-on with links to Copernicus and Carbon Brief and reminders that cherry-picking data and worrying about “air conditioners near sensors” ignores global ocean heat and satellite records. The 🔥 continues when renewiltord declares major green groups oppose nuclear, solar, and wind, which triggers a brawl over energy solutions and who’s blocking what. Meme-watch: “El Niño did it” vs “Shipping rule made Earth tan” becomes the thread’s accidental bumper sticker. Verdict: the planet’s boiling, and so are the replies.
Key Points
- •2025 is projected to end as the second-hottest year on record, behind 2024.
- •The past three years each exceeded 1.5°C above preindustrial levels, per Copernicus, breaching the international target temporarily.
- •Zeke Hausfather’s analysis (Carbon Brief) assesses four drivers: volcanic water vapor, increased solar output, El Niño, and reduced sulfur pollution.
- •Volcanic and solar factors explain less than half of the recent temperature rise; El Niño accounts for 2024 warmth but not early 2023.
- •Declines in sulfur dioxide from coal and shipping likely contributed to warming; uncertainty remains whether the surge is temporary or accelerating.
