More, less, or about the same significance as the reduced sulphur particles from global shipping these past two years, the unusual absence of Saharan dust, and the growing El Niño swing? https://www.carbonbrief.org/state-of-the-climate-growing-el-nino-threatens-more-extreme-heat-in-2023/ https://www.carbonbrief.org/state-of-the-climate-growing-el-... https://twitter.com/MichaelRLowry/status/1667965015503126529 https://twitter.com/MichaelRLowry/status/1667965015503126529 https://twitter.com/LeonSimons8/status/1669667629844267008 https://twitter.com/LeonSimons8/status/1669667629844267008

  "This eruption could impact climate not through surface cooling due to sulfate aerosols, but rather through surface warming due to the radiative forcing from the excess stratospheric H2O." ...from the abstract of the study referenced in the article. https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2022GL099381 https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/202...

    There’s a very long way from “could impact climate” to “is a significant contributor”.

      Increasing stratospheric water vapour by five percent is not insignificant.

      Some men need to be bit by a dog, told the breed of the dog, the time they were bitten by the dog, which extremity the dog bit, whether one should panic after being bitten by a dog, and if the dog did in fact have teeth before knowing they have been bit by a dog.
