By Andy May In part 3 we discussed the relationship between changes in solar activity and climate changes. Exactly how solar changes affect climate is not understood. It isn’t the…

Climate Model Bias 3: Solar Input
By Andy May In part 2 we discussed the IPCC hypothesis of climate change that assumes humans and our greenhouse gas emissions and land use choices are the climate change…
Climate Model Bias 2: Modeling Greenhouse Gases
By Andy May Since the late 19th century, with the work by Svante Arrhenius, climate models have been used to estimate the amount of global warming due to human greenhouse…
Climate Model Bias 1: What is a Model?
By Andy May There are three types of scientific models, as shown in figure 1. In this series of seven posts on climate model bias we are only concerned with…
Proof that the Spencer & Christy Method of Plotting Temperature Time Series is Best
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.
Gavin’s Plotting Trick: Hide the Incline
In fact, as the evidence above shows, it is our accusers who are engaged in “trickery” and deception by “hiding the incline”
Spencer vs. Schmidt: Spencer Responds to RealClimate.org Criticisms
…he seems to be trying too hard to refute my claims while using weak (and even non-existent) evidence.
Dr. Roy Spencer: New Article on Climate Models vs. Observations
…here’s a comparison between models and observations for the U.S. Corn Belt near-surface air temperatures in summer:
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.
A Test of Skill for Climate Models
Do climate models offer a firm basis for attempting to re-engineer the entire global economy?
AI Researchers Pushing Their Value to Climate Activists
According to advocates, AI can generate better flood predictions than physics and geography. But is this just more magic box thinking?
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.
Modeling HadCRUT5 with CO2 and without CO2
By Andy May I hate statistics, as many of you know. Some people think statistics and/or statistical models that meet standard statistical criteria are facts. The IPCC can be like…
Models Vs. Reality: Sea Turtle Edition
Sea turtles in Florida are handling the climate crisis quite well.
The Marathon of Misguided Climate Alarmism: A Review of “Feasibility of the Olympic marathon under climatic and socioeconomic change”
The paper, shrouded in the guise of scientific inquiry, seems more like an exercise in creative speculation, leveraging the universal appeal of the Olympics to propagate the narrative of climate…
Testing A Constructal Climate Model
Guest Post by Willis Eschenbach ABSTRACT A simple theoretical constructal model of the operation of the climate system was envisioned by Dr. Adrian Bejan and several others. It posits that…
Climate Models Wrong on East Pacific… “We Don’t Know Why This Cooling Is Happening”
The East Pacific Ocean’s progressive cooling over the past 30 years contradicts climate models predicting warming due to greenhouse gas emissions. This discrepancy impacts global agriculture, as the ocean’s temperature…
The Myth of “Settled” Climate Science: A Revelatory Study on Cloud Formation
Trees, Clouds, and the Unsettling Truth about Climate Science In a recent revelation from the international CLOUD project at the nuclear research center CERN, researchers have identified sesquiterpenes—gaseous hydrocarbons released…
Challenging the Mathematical Basis of General Circulation Models
His framework invariably ensures well-posed reduced systems for limited domains and has broader applicability, including mesoscale and equatorial atmospheric behaviors, oceanic dynamics, and plasma physics.
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…
