Repeated Trials, Autocorrelation, and Albedo

Guest Post by Willis Eschenbach OK, quick gambler’s question. Suppose I flip seven coins in the air at once and they all seven come up heads. Are the coins loaded? Near as I can tell, statistics was invented by gamblers to answer this type of question. The seven coins are independent events. If they are…

Silver Ants

Guest Post by Willis Eschenbach I stumbled across a lovely article about the Saharan silver ant over at phys.org. These ants have special hairs that reflect strongly in the visual and radiate strongly in the infrared. They show a photo of the ant hairs under a couple different amounts of magnification: Figure 1. Photograph from the phys.org…

UAH, MSU, TLT, and other Acronyms

Guest Post by Willis Eschenbach The satellite-based atmospheric temperature dataset is one of the better datasets in climate science. Drs. Roy Spencer and John Christy have long been scientific heroes of mine because of the quality of their work in the creation, analysis, corrections, and curation of the dataset.  It is kept at the University…

TAO Buoys Go Hot And Cold

Guest Post by Willis Eschenbach I got to thinking about how I could gain more understanding of the daily air temperature cycles in the tropics. I decided to look at what happens when the early morning (midnight to 5:00 AM) of a given day is cooler than usual, versus what happens when the early morning…

Solar Fossil Fueled Fantasies

Guest Post by Willis Eschenbach. Sometimes when I’m reading about renewable technologies, I just break out laughing at the madness that the war on carbon has wrought. Consider the Ivanpah solar tower electric power plant. It covers five square miles in Southern California with mirrors which are all focusing the sun on a central tower.…

The Daily Albedo Cycle

Guest Post by Willis Eschenbach I discussed the role of tropical albedo in regulating the temperature in two previous posts entitled Albedic Meanderings and An Inherently Stable System. This post builds on that foundation. I said in the latter post that I would discuss the diurnal changes in tropical cloud albedo. For this I use…

Can We Tell If The Oceans Are Warming?

Guest Post by Willis Eschenbach Well, I was going to write about hourly albedo changes, honest I was, but as is often the case I got sidetractored. My great thanks to Joanne Nova for highlighting a mostly unknown paper on the error estimate for the Argo dataset entitled On the accuracy of North Atlantic temperature and…
