I hope this is sufficient evidence of the superiority of our way of plotting different time series when the intent is to reveal differences in long-term trends, rather than hide those differences.

Scientists: Nearly 4 Decades of Climate Model Failure Undermines Confidence In Future Predictions
“[I]f these models cannot reproduce past variations, why should we be so confident about their ability to predict the future?”
Do CMIP5 models skillfully match actual warming?
CMIP5 models have not been at all skillful in predicting future warming; they have matched the illustrated 1970–2020 observed warming (which was past rather than future warming until the late 2000s, when CMIP5 models…
Is the Arctic September Sea Ice Doomed to Disappear in the 2030’s?
K23 takes advantage of the rejected CMIP 6 MMM and comes to strongly biased results. It’s overdue for the editorial board of “Nature communication” to check the peer review process…
Transient Climate Response from Observations 1979-2022
The best estimate of TCR based on CMIP6 models (the red line in Fig.1) is 1.6K / 2*CO2, following the cited paper.
50-Year U.S. Summer Temperature Trends: ALL 36 Climate Models Are Too Warm
Given that U.S. energy policy depends upon the predictions from these models, their tendency to produce too much warming (and likely also warming-associated climate change) should be factored into energy…
Updated Climate Models Clouded by Scientific Biases, Researchers Find
After all, the ultimate goal of any model evaluation study is to help improve those models.”
Second Place Winner WUWT Student Essay Contest
Man-made catastrophic global warming doesn’t exist, and it is time to stop hurting ourselves by acting as if it does.
Quantifying CMIP6 Model Uncertainties in Extreme Precipitation Projections
Despite the overestimated inter-model spread, our results show a robust enhancement of extreme precipitation with more than 90% of models simulating an increase of RV20.
Inside Climate News Confuses Models with Reality
If the current models used for temperature prediction are not accurate, then the food production models that rely on them cannot be expected to be accurate either.
Outside The Black Box
Models that need model-specific input to replicate the known past, violate the most basic criteria of science to earn the label “scientifically proven”, independent of the “proven physics” they are…
Swiss Analysis: Climate Models Running Too Warm, Falsely Calibrated…IPCC Needs “To Review Its Findings”
“The warming of the last 20 years has been caused more by changes in clouds than by the classical greenhouse effect,” say study authors Fritz Vahrenholt and Hans-Rolf Dübal
IPCC Enters “Into Thin Air”. German Scientists: IPCC “In A Hopeless Situation”…”Stained Scientists”
The wide range of CO2 climate sensitivity had long been a thorn in everyone’s side. For 30 years the range existed, without progress. Now one has simply reduced the span…
GHGs, California, and the EPA: a golden braid of off-the-rails
The unavoidable conclusions are that the SAFE Vehicle Rule serves no ameliorative purpose because the EPA CO2 endangerment finding has no scientific merit.
CMIP6 ECS
It is apparent that those who believe in anthropogenic global warming do not understand the intractable fundamental problem with their climate model approach. They are digging themselves a deeper hole.…
Projecting manmade climate change: scenarios to 2050
Climate impact assessments are being biased in an alarming direction by continued inclusion, and especially sole reliance, on RCP8.5. For climate change to 2050, RCP4.5 and RCP6.0 are the most…
Compensation between cloud feedback + ECS and aerosol-cloud forcing in CMIP6 models
The new open-access paper – the senior author of which, Gabriel Vecchi, is a well known professor of geosciences at Princeton University – provides further evidence that high ECS CMIP6…
High end of climate sensitivity in new climate models seen as less plausible
Researchers at Princeton University and the University of Miami reported that newer models with a high “climate sensitivity” — meaning they predict much greater global warming from the same levels…
CMIP6 adds more value in simulating extreme temperatures in China
Climate models have provided an avenue for studying the possible changes in extreme temperatures in the future; and in this respect, to ease of comparison across models from different modelling…
Disconnect in the relationship between GMST and ECS
Abstract. An analysis is presented of he disconnection between the CMIP5 and CMIP6 Historical and Future periods when considering the relationship of the individual model GMST changes and the climate…
CMIP6 Update
This essay extends the previously published evaluation of CMIP5 climate models to the predictive and physical reliability of CMIP6 global average air temperature projections.
Emergent constraints on TCR and ECS from historical warming in CMIP5 and CMIP6 models
I note that Earth Systems Dynamics published the paper despite one of the two peer reviewers recommending against acceptance without further major revisions. But neither of the reviewers appear to…
Hot Summer Epic Fail: New Climate Models Exaggerate Midwest Warming by 6X
Contrary to popular perception, the U.S. Midwest has seen little long-term summer warming. For precipitation, the slight drying predicted by climate models in response to human greenhouse gas emissions has…
