What does "reliably measured" mean? Isn't the record 134F, measured in 1913? I wonder what the backstory here is.

  Invalidating historical record highs is erasing history to sell a narrative.

    Or maybe it's fact checking in the face of global hysteria. A comment I left 11 days ago about how little we actually know for certain: https://news.ycombinator.com/item?id=27658488 https://news.ycombinator.com/item?id=27658488

    The ones selling the narrative aren't the scientists with petabytes of accurate, digitally recorded data showing a global warming trend over decades highly correlated to human industrial activity who also agree the temperature in 1913 was recorded inaccurately, but rather those who would point to one record from 1913, or maybe 20 records from history, to show "global warming is a myth".
    - delecti 5y ago
      I think you have the logic backwards there. It seems that comment was arguing that scientists want to falsely suppress the 1913 record, so they can also falsely push climate change science. It's wrong, but it's internally consistent.
    - chrisco255 5y ago
      Scientists (as well as farmers) in 1913 knew perfectly well how to record temperature. Digital measurements only matter in precision far less than 1 degree F. Mercury is very consistent in how it responds to temperature. Not only was it likely recorded accurately, it's extremely unlikely the 134F record was off by 4 degrees or more. It also had 5 days in a row above 129F that year. See: https://www.nps.gov/deva/learn/nature/weather-and-climate.htm https://www.nps.gov/deva/learn/nature/weather-and-climate.ht...

June 2021 was on par with the average of the last 30 years, across the globe, according to digital satellite data: http://www.drroyspencer.com/2021/07/uah-global-temperature-update-for-june-2021-0-01-deg-c/ http://www.drroyspencer.com/2021/07/uah-global-temperature-u... Greenland also had anomalous ice gains in June: http://polarportal.dk/en/greenland/surface-conditions/ http://polarportal.dk/en/greenland/surface-conditions/ I am not selling anything. But historically speaking, those who have sought to erase history have but one motive.

Im seeing a lot of news lately about record heat waves. Presumably this has been happening for a few years now though although I’m not sure where i could get accurate info on that. Did the media just start pushing this to the from because its now a hot button issue that is selling more clicks? Not saying its bad if it helps us take more action against global warming its likely good. But I’m still curious.
- bwship 5y ago
  I think these are some of the highest recorded temps, like in Seattle and Portland ever. And it being July, if it is hitting record temps in California, Nevada and Arizona, then it might be a bit hotter than in years past.

  It’s not just a presumption and it isn’t media just “pushing this.” https://climate.nasa.gov/vital-signs/global-temperature/ https://climate.nasa.gov/vital-signs/global-temperature/ > Nineteen of the warmest years have occurred since 2000, with the exception of 1998. The year 2020 tied with 2016 for the warmest year on record since record-keeping began in 1880 (source: NASA/GISS). This research is broadly consistent with similar constructions prepared by the Climatic Research Unit and the National Oceanic and Atmospheric Administration.

    You and others have not read my comment correctly. I know this is the case. Im asking why right now it is always on the front page all of a sudden and am simply asking if this is because the frequency has increased or is because its now profitable to print. But from your own link it is the media pushing this now. Because this was really never something you saw in the news before but all of the sudden you see it ever other day.

      > Im asking why right now it is always on the front page all of a sudden I've been seeing news reports on continuous heat-record-breaking for at least ten years. Perhaps you haven't been reading decent science news until recently. But one would also expect reporting on a problem to increase as the problem gets worse, yes?
Proven 5y ago
a) measurements haven't been reliable so we don't know if that is really the hottest ever, or not b) reliable (they say) measurements go back only few decades, so could very well be "the hottest in last 50 years" which isn't noteworthy. where I live, recent summers were cooler than usual

Must be a regional phenomenon. Greenland is seeing record growth to the Surface Mass Balance (ice growth) & the eastern US is colder than average. https://twitter.com/bogho_s/status/1413567978583601154 https://twitter.com/bogho_s/status/1413567978583601154

  There's a heat dome over the west similar to the one that brought 126 degree temperatures to Canada 2 weeks ago, but less extreme. Generally, Greenland is losing gigatons of ice every year. https://arctic.noaa.gov/Portals/7/easygalleryimages/8/465/arc19_greenland_tedesco_fig3.jpg https://arctic.noaa.gov/Portals/7/easygalleryimages/8/465/ar...
  - briantakita 5y ago
    It seems like Greenland is now accumulating gigatons of ice since bottoming out. Considering that have recently exited the Modern Warm Period, the graph you presented hitting the minimum of ice & the recent accumulation makes sense. The weakening Geomagnetic Field strength also seems to drive the weakening jetstreams, resulting in increased polar & equatorial vortexes. Some areas are abnormally hot & some are abnormally cold. https://news.sky.com/story/china-at-least-20-runners-die-as-extreme-weather-hits-cross-country-mountain-race-12314304 https://news.sky.com/story/china-at-least-20-runners-die-as-... Records are funny things, since they also depend on technology that has existed in a minuscule fraction of Earth's history to measure. Much of these advancements happened to have occurred following the Maunder Minimum, which featured "the year without a summer" into the Modern Warm Period. Now we have left the Modern Warm Period & have instability caused by the weakening Geomagnetic field, which occurs cyclically around every 12000 years.
    - moultano 5y ago
      It isn't the magnetic field that's causing weakening jetstreams, it's the rapid warming of the poles and the loss of the polar ice cap. https://www.nature.com/articles/srep45242 https://www.nature.com/articles/srep45242
