From the latest @yaleclimatecomm.bsky.social survey: "The percentage of registered voters who say they hear about global warming in the media dropped 11 percentage points from 2024 (30%) to 2025 (19%), which is the lowest it has been since the question was first asked in 2015." This is on you media!

nice thread Daniel, but I'm not sure I get your point here. If we're interested in global influence on ocean heat & evaporation, we wouldn't look to the Nino3.4 region anyway, we'd look further west where absolute SSTs are still the highest:

I discussed the "Godzilla" El Niño and how it's likely to combine with human-caused warming to supercharge extreme weather in the months ahead with @caitrionaperry.bsky.social of #BBCNews, live from #ClimateWeekNYC

There is a half century of work using historical documentary evidence to assess past El Nino behavior (with limited fidelity). This evidence is even discussed in the original MBH98 "hockey stick" article: michaelmann.net/sites/defaul...

Michael E. Mann @michaelemann.bsky.social · 21/09/2026

Yes, this is a huge El Niño. No, @theguardian.com we do not have a reliable thousand year-long record of El Niño (e.g. a continuous reconstruction of the Niño3 or Niño3.4 SST index) so this statement is not warranted. What's the attribution for that claim? www.theguardian.com/environment/...

There are many things I don't want. Being buried in a pet cemetery is near the top of the list. And od-ing on DDT is right up there too. One of my greatest achievements on social media was being "liked" by a Ramone.

This is being widely reported as a Dem +8 advantage. But looking at the cross-tabs, there's a Dem +11 likely voter advantage on "which party would you prefer to see control Congress" www.nytimes.com/interactive/...

August was the warmest month on record for the planet. I discussed the implications with #BBCNews:

Michael E. Mann @michaelemann.bsky.social · 11/09/2026

Now that the summer peak is behind us, we can confidently conclude that 2024 will retain its title for warmest day on record, with 2023 coming in 2nd and 2026 coming in a close 3rd. August was nonetheless the warmest month on record, as a growing El Nino event adds to steady ongoing warming.

p.s. I don't recall saying that the CO2 increment was decreasing. I have said it's expected to plateau, and that appears to be happening. If you can find a citation for me claiming it is decrease, please provide. Here's Gemini's summary of what I've stated about the topic:

How about the actual data? Here it is. Note that the 2015-2016 and 2023-2024 positive spikes are due to El Nino (you can read more about that connection here: www.scientificamerican.com/article/huma...)

It's not a matter of what you think. There is careful science that has been done here, and scientific consensus as summarized in the reports of the IPCC. See e.g. #SR15:
