The source for the article is the Climate Change Institute at University of Maine [0]. The Institute's Climate Reanalyzer also has some visual data of historical daily sea surface temps that is referenced quite a bit these days. Data only stretches back to the late 70s/early 80s, but many of the hottest trending years are within the last decade.

Claiming something is the hottest day on earth when your data only goes back half a century is the reason people think all these groups are little more than grifters. It’s bad science and hyperbole.

  It would be beneficial to your understanding if you read the article. The title is slightly misleading. > Even though the dataset used for the unofficial record goes back only to 1979, Kapnick said that given other data, the world is likely seeing the hottest day in “several hundred years that we’ve experienced.”

    Even then, “hundreds of years,” is not the hottest day in earth.

  Record setting was never science. You need to separate the people doing science from the people making marketing posts. Record setting is marketing.

  I used to think the same thing, and it was the argument that my dad would make against climate change (i.e. "we've only been tracking the temperature since the late 1800's"). But then I found out about climate proxies: https://en.m.wikipedia.org/wiki/Proxy_(climate) https://en.m.wikipedia.org/wiki/Proxy_(climate)

    There was a brief spike at the beginning of the Holocene, a bit over 10,000 years ago, when there was a brief slightly warmer average. Someday soon-ish we seem likely to have a day higher than whatever peak happened then. We won't know it but the odds are already non-zero and rising that we've crossed that threshold. Walking back in time, we have to go to 115k-130k years ago to find a hotter time period. That's during a brief Eemian period, before the last glacial period (where the glaciars retreated for good). This is called the Pleistocene era. Heaven help us if we breach that peak, whatever it was, but for a couple hundred years it looks like it was +3.5 or 4 C hotter on average than our 1960-1990 average. It was around 2.5m years ago that the earth actually stayed consistently hotter: the Pilocene era. The data isnt exactly precise but the conclusion should be resounding & clear. https://en.wikipedia.org/wiki/Geologic_temperature_record#Overall_view https://en.wikipedia.org/wiki/Geologic_temperature_record#Ov...

  Direct temperature measurements go back century or so, but proxies for temperature go back much further. Error bars may be larger but it's not like there's nothing to base the models on.

  Bill McKibben's reporting says scientists estimate via temperature proxies that this is the hottest the earth has been in 125,000 years. Is that better for you? https://billmckibben.substack.com/p/no-human-has-ever-seen-it-hotter https://billmckibben.substack.com/p/no-human-has-ever-seen-i...

  Blaming the researchers for whatever sensational and misleading headline apnews puts on their work isn't really fair. Be better.

  Sure, there were very high temperatures in the Earth past. There were higher CO2 levels too. The problem is the acceleration, the rate of change. There never were such changes in such short time period as there are today. You have a quant in your nickname, I'm pretty sure you can understand what this means. To make an analogy - you have an oven and it's temperature is currently 150C, way less than the maximum observed 250C. But the problem is that the regulator is set to Max now.

Not just hottest day. As of 2023 we now have multi-month streaks of: Antarctic Sea Ice Extent records: https://www.climate.gov/news-features/event-tracker/antarctic-sea-ice-reaches-early-winter-record-low-june-2023 https://www.climate.gov/news-features/event-tracker/antarcti... Ocean Temperature records: https://www.theinvadingsea.com/2023/05/01/record-warm-oceans-temperatures-el-nino-climate-change/ https://www.theinvadingsea.com/2023/05/01/record-warm-oceans... 2-Meter Air Temperature records: https://climatereanalyzer.org/clim/t2_daily/ https://climatereanalyzer.org/clim/t2_daily/ You have to look back 3 million years to see the same GHGe concentrations and temperatures that earth is reaching now (the two are closely correllated throughout most of earth history, and easily explained by science - the greenhouse effects, and the thin earth surface and atmosphere mostly acting as a closed system). We see that both ice, ocean and air are heating up and accellerating as of 2023. What is observed now is in-line with projections, such as summed up in this hobbyist article (taken with some grains of salt): https://medium.com/@samyoureyes/the-busy-workers-handbook-to-the-apocalypse-7790666afde7 https://medium.com/@samyoureyes/the-busy-workers-handbook-to... Even if some of what is summarized on the notes linked above may be exhaggerated, it seems this is now happening sooner, faster and more relentless than IPCC and scientific consensus have found so far. Note that any averages or aggregates on measurements, such as those IPCC and climate scientists use, will lag reality by approximately half the period used. So using multi-year averages means we will already be too late when long-term averages show accelleration, even if final calculations will be more stable ("smoother") by using averages. Of course there's no way to really "cheat" this, but that means when we now see we are in uncharted territory, it should be taken seriously.
