Despite the confidence with which the United Nations Intergovernmental Panel on Climate Change (IPCC) claims to have “settled the science” around the detection and attribution of climate change, this challenging scientific debate has not yet been satisfactorily resolved. The IPCC did not provide a strong enough argument for its choice of the available global temperature trends, and the same applies to its choice of the available Total Solar Irradiance (TSI) datasets.
That is the conclusion of three PhD scientists in a recent study published on December 11, 2024. They continue: “The IPCC was overly confident and premature in its detection and attribution statements. The scientific debate is still ongoing, and the scientific community is not yet in a position to establish whether the observed temperature changes since the 1800s are mostly natural, mostly human-caused, or a mixture of both.”
“We also have concerns about the IPCC’s handling of the ongoing scientific debate over the changes in solar activity (TSI) since 1850. The TSI estimate used by the computer model simulations that contributed to the IPCC analysis was guaranteed to show that global warming was “mostly human-caused.” However, we have identified at least 27 different estimates of the changes in TSI since 1850. Several of these estimates suggest that global warming is “mostly natural,” and several suggest that global warming is a mixture of natural and human-caused factors.”
