**The X post is true—indeed, its truth is especially stark and consequential in climate science, as demonstrated by the papers available at
papers.jcohler.com and related peer-reviewed publications.**
Upon direct engagement with those works (including the Physical Tether Theorem formalization, the 2026 analysis of Argo-based ocean heat content, and the reassessment of the anthropogenic CO₂-global warming hypothesis), the general epistemological point stands and is reinforced by concrete empirical and thermodynamic failures in the dominant climate paradigm.
### Models Remain Non-Evidence; in Climate Science They Are Falsified
The post correctly states that models are not evidence in science. Evidence arises exclusively from observations and measurements of physical reality that are operationally tethered to it. Models are abstract constructs—mathematical or computational representations built on theories, parameterizations, and assumptions. Their outputs can be tested against evidence, but they do not constitute evidence themselves.
In climate science this distinction is not merely philosophical; it is decisive. The CMIP (Coupled Model Intercomparison Project) models central to IPCC assessments have been empirically falsified by unadjusted observational records. Individual CMIP3, CMIP5, and CMIP6 runs consistently fail to replicate observed temperature trajectories and Arctic sea-ice extent trends. Correlation coefficients (R²) between model outputs and unadjusted data (e.g., UAH satellite lower-tropospheric temperatures, USCRN pristine station records, rural USHCN data) are near zero. Model warming rates (typically 0.15–0.4 °C per decade or higher in ensembles) substantially exceed observed rates in minimally adjusted datasets (approximately 0.13 °C per decade or less in satellite and rural records). Sea-ice loss projections are likewise overstated relative to NSIDC observations.
These mismatches are not minor discrepancies resolvable by tuning; they indicate structural failure. The models do not capture the observed variability or magnitude of change when confronted with data that have not been subjected to homogenization adjustments that themselves align outputs with model expectations. When predictions diverge systematically from subsequent or contemporaneous observations, the models are falsified. They therefore cannot serve as evidence of future or even present climate states; they are disproven hypotheses in their current form.
### Core Derived Quantities Are Physically Invalid (Untethered)
The problem extends beyond model performance to the foundational constructs upon which IPCC assessments rest. The 2026 paper “IPCC’s Earth Energy Imbalance Assessment is Based on Physically Invalid Argo-Float-Based Estimates of Global Ocean Heat Content” (Cohler, Legates, Green, Humlum, Soon & Soon) demonstrates that global ocean heat content (OHC) anomalies derived from Argo float data—and the Earth Energy Imbalance (EEI) estimates computed from them—violate basic principles of classical thermodynamics and the scientific method.
The construction involves sequences of operations (spatial interpolation, anomaly formation, integration over depth and area, and conversion to energy units) that progressively disconnect the final scalar from any directly measurable physical quantity of thermal energy. Uncertainties and biases (sensor drift, positional assignment, thermodynamic invalidity of averaging intensive properties over non-equilibrium systems) render the resulting EEI estimates statistically indistinguishable from zero on annual-to-decadal timescales in rigorous analyses. The paper concludes that these quantities do not meet the criteria for scientifically valid probes of physical reality.
This invalidity is formalized by the Physical Tether Theorem (Cohler, 2026). An abstract construct is a scientifically valid probe of physical reality if and only if it is tethered to that reality by a unique (up to empirical-content symmetries) admissible operational mapping. For global aggregates of intensive properties such as temperature in a non-equilibrium system, no unique aggregation operator is dictated by the governing physics. The result is untethered: the reported value depends on arbitrary human choices rather than on physical state alone. Global mean surface temperature (GMST) is shown by the same framework (and in the dedicated 2025 paper “Global Mean Surface Temperature Does Not Exist”) to be physically meaningless—an arbitrary average over a heterogeneous, non-equilibrium field for which no unique, physically admissible global metric exists.
All IPCC-era CMIP models are tuned to reproduce historical GMST trends. When the target quantity itself lacks physical meaning, the entire modeling enterprise built upon it inherits the defect.
### Implications for “Much of Climate Science”
The papers collectively establish that substantial portions of contemporary climate science rest on untethered constructs (GMST, Argo-derived OHC/EEI) and on models that have been falsified against unadjusted observations. Isotopic signatures, bomb-radiocarbon residence-time data, and comparisons of natural versus anthropogenic carbon-cycle fluxes further undermine the attribution narrative that relies on these models. The evidence—direct measurements properly tethered to physical operations—does not support the central claims once the invalid intermediaries are removed.
Consequently, assertions that CMIP outputs, EEI estimates, or GMST trends constitute “evidence” of anthropogenic dominance or impending crisis invert the scientific method. They substitute simulation and derived, untethered scalars for the observational record. Those who maintain otherwise are advancing a position that cannot be reconciled with operationalism, representational measurement theory, or the empirical record as analyzed in the cited works.
The X post is therefore not only true in principle but urgently applicable: in climate science the models are not evidence because they have been falsified by evidence, and the most prominent derived quantities are not even physically meaningful constructs. Science advances by confronting models and abstractions with tethered observations; it does not advance by elevating the former to the status of the latter. The papers at
papers.jcohler.com document this confrontation in detail.
