Climate Model Bias 1: What is a Model?

By Andy May Christian Freuer has translated this post into German here. This is the first post of a seven-part series on bias in the IPCC AR6 report, here are links to the other six parts: 2. Modeling Greenhouse Gases 3. Solar Input 4. Convection and atmospheric circulation 5. Storminess 6. IPCC AR6 WGII 7.Continue reading “Climate Model Bias 1: What is a Model?”

Sorry, the Little Ice Age Does Exist

By Andy May This post has been translated into German by Christian Freuer here. Renee Hannon (@hannon_renee) pointed out that Raphael Neukom, et al. (2019) compares the modern instrumental temperature record to the Pages2K proxy temperature record and declares that: “… we find that the coldest epoch of the last millennium—the putative Little Ice Age—isContinue reading “Sorry, the Little Ice Age Does Exist”

Hurricane Frequency and Sunspots

By Andy May Today, Roger Pielke Jr. posted a plot of the 3-year frequency of global major hurricanes (he uses a simple count of them) created by Ryan Maue (@RyanMaue). Dr. Maue also posted this plot on his twitter feed here. I noticed it looked like an inverse sunspot plot and overlaid the SILSO monthlyContinue reading “Hurricane Frequency and Sunspots”

Lazard’s LCOE

By Andy May This post has been translated into German by Christian Freuer here. Lazard’s levelized cost of energy (LCOE) is cited on the internet all the time as the source for “solar and wind are cheaper than fossil fuels.” They don’t really mean “energy,” they mean “electricity.” The world consumed only 18% of itsContinue reading “Lazard’s LCOE”

Climate, CO2, and the Sun

By Andy May Christian Freuer has translated this post into German here. In my previous post on multiple regression of known solar cycles versus HadCRUT5, I simply threw the solar cycles, ENSO, and sunspots into the regression blender and compared the result to various models that included CO2. Before reading this post, it is aContinue reading “Climate, CO2, and the Sun”

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 that. They statistically model global surface temperatures with models of volcanic and anthropogenic forcing and compare the model to one with only volcanic forcing. ThenContinue reading “Modeling HadCRUT5 with CO2 and without CO2”

John Constable’s talk at Universidad de las Hespérides

By Andy May h/t Wim Röst The Universidad de las Hespérides is in the Canary Islands, off the coast of Morocco. The Hespérides are the nymphs of the evening and golden sunsets, so I imagine it is a beautiful location to travel to. Dr. Constable’s talk can be viewed in full here. The beginning isContinue reading “John Constable’s talk at Universidad de las Hespérides”

Australia Warns Ferries about EVs

By Andy May h/t Don Keiller and Ken Gregory Australia’s Maritime Safety Authority has issued a domestic commercial vessel safety alert on the risks of ferrying battery powered cars (EVs), download it here. Each ferry operator must conduct a risk assessment for their vessel to ensure that they are capable of dealing with potential EVContinue reading “Australia Warns Ferries about EVs”
