Climate Model Projections Significantly Diverge from Paleoclimate Analogs
By Renee Hannon Introduction Over the past million years, our Earth displays a rhythmic beat when exiting full glacial cycles and entering interglacial warm periods. The characteristics and duration of…
Comparison Between Observational Data and Model Projections for Hot Days in Northern Australian Regions
Guest essay by Dr. B Basil Beamish In a recent WUWT post I looked at the number of hot days (Tmax > 35 °C) projected by climate models for Cairns as…
Comparison Between Observational Data and Model Projections for Cairns (AU) Hot Days
Guest essay by Dr. B Basil Beamish On Friday 29 October 2010, The Cairns Post published an article based on a Queensland Government report entitled “Climate change in Queensland: What…
EPA Chief doesn't know whether climate model projections are accurate
“I do not know what the models actually are predicting that you are referring to” Story submitted by Eric Worrall EPA Chief Gina McCarthy struggled to answer questions, at a…
Fossils cast doubt on climate-change model projections on habitats
From the University of Oregon Mammals didn’t play by the rules of modeling on where they migrated to survive last ice age, says UO researcher EUGENE, Ore. — Nov. 18,…
IPCC AR5 draft leaked, contains game-changing admission of enhanced solar forcing – as well as a lack of warming to match model projections, and reversal on 'extreme weather'
This post will remain at the top for a few days, new stories will appear below this one UPDATE1: Andrew Revkin at the NYT weighs in, and semi endorses the…
A refreshing change on sea level policy – use historical data rather than model projections
An update to what we reported here yesterday – Science vs AGW Advocacy in North Carolina, from HamptonRoads.com: N.C. Senate approves sea level calculation bill The North Carolina Senate has…
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.
Models In Turmoil: Underestimation Of Satellite-Based Cloud-Aerosol Interaction “Hampering Climate Change Projections”
By acting as cloud condensation nuclei (CCN), aerosols act as cloud condensation nuclei and thus can alter cloud properties and precipitation. This influences the Earth’s radiation budget and hence climate…
More on Curry's climate model study saying they are 'not useful as projections for how the 21st century will actually evolve.'
Guest essay by Larry Hamlin The new climate model study by Dr. Curry addressed in the February 21 WUWT article provides some very powerful conclusions regarding the unsuitability of using…
Unsettled science: New study challenges the consensus on CO2 regulation – modeled CO2 projections exaggerated
I’m really quite surprised to find this paper in Nature, especially when it makes claims so counter to the consensus that model projections are essentially a map of the future…
Climate Model Bias 7: WGIII
By Andy May In the previous report, part 6 of this series, I discussed the bias in AR6 WGII. The major bias in the report stemmed from ignoring the benefits…
Climate Model Bias 6: WGII
The IPCC AR6 WGII report examines the impact of climate change but ignores the benefits of warming and additional CO2.
Climate Model Bias 5: Storminess
By Andy May In part 4 the impact of convection and atmospheric circulation on climate was discussed. When circulation patterns change, they change the speed and efficiency of the transport…
New Study: Climate Models Get Water Vapor Wildly Wrong – A ‘Major Gap in Our Understanding’
From the NoTricksZone By Kenneth Richard on 19. February 2024 “Here, we have demonstrated a major discrepancy between observation-based and climate model-based historical trends in near-surface atmospheric water vapor in arid and semi-ari…
Climate Change Weekly #495: New Research Further Demonstrates Problems with Surface Temperature Records and Models
And does Michael Mann really have a strong case for defamation? He himself frequently spreads false and malicious rumors about colleagues who challenged his science. Listen to his explanation for falsely…
Models Wrong Again: “Hotter Weather Not Diminishing Runoff, River Discharge”!
These results are somewhat in contrast to climate projections, where runoff is expected to decrease only over southern Europe.
Junk Science Alert: Met Office Set to Ditch Actual Temperature Data in Favour of Model Predictions
…using this highly politicised method would indicate that reality is rapidly departing from the Met Office station.
Climate Models have Accurately Predicted 30 Years of Warming
Pro: Climate Models Have Been Demonstrated to be Accurate. From NASA By Alan Buis,NASA’s Jet Propulsion Laboratory An animation of a GISS (Goddard Institute for Space Studies) climate model simulation…
