Please convince me that I am wrong, but runaway extreme global warming is not in doubt.
Barry https://berkeleyearth.org/global-temperature-report-for-2024/ Global Temperature Report for 2024 Posted on January 10, 2025 by Robert Rohde Berkeley Earth, a California-based non-profit research organization, has been preparing independent analyses of global mean temperature changes since 2013. The following is our report on global mean temperature during 2024. We conclude that 2024 was the warmest year on Earth since 1850, exceeding the previous record just set in 2023 by a clear and definitive margin. This period, since 1850, is the time when sufficient direct measurements from thermometers exist to create a purely instrumental estimate of changes in global mean temperature. The last ten years have included all ten of the warmest years observed in the instrumental record. The warming spike observed in 2023 and 2024 has been extreme and represents a larger than expected deviation from the previous warming trend. The spike has multiple causes, including both natural variability and man-made global warming from the accumulation of greenhouses gases; however, as discussed below, we believe additional factors are needed to explain the full magnitude of this event. Reductions in low cloud cover and man-made sulfur aerosol pollution are likely to have played a significant additional role in recent warming. Over the previous 50 years, global warming has preceded in an almost linear fashion, consistent with an almost linear increase in the total greenhouse gas forcing. The warming spike in 2023/2024 suggests that the past warming rate is no longer a reliable predictor of the future, and additional factors have created conditions for faster warming, at least in the short-term. The global annual average for 2024 in our dataset is estimated as 1.62 ± 0.06 °C (2.91 ± 0.11 °F) above the average during the period 1850 to 1900, which is traditionally used a reference for the pre-industrial period. This is first time Berkeley Earth has reported an annual average above 1.6 °C (2.9 °F), and the only second time that Berkeley Earth has reported any year exceeding the key 1.5 °C (2.7 °F) threshold, after slightly doing so in 2023. Due to uncertainties and differences in methodologies, other groups are expected to report 2024 as slightly cooler. The ECMWF’s Copernicus research service joins us in just barely exceeding 1.6 °C (2.9 °F), while other groups are somewhat cooler. The differences between Berkeley Earth’s analysis and that of other groups is discussed at the end of this report Note how the last years are rising a lot each year, out of the pack, compared to the 50's, when the curves were close together. https://climatereanalyzer.org/clim/t2_daily/?dm_id=world https://arctic-news.blogspot.com/ -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
