An Analysis of the Earth’s Energy Budget

Guest post by Philip Mulholland 1. Introduction. The following two figures, showing the principal features of the Earth’s Energy Budget, were published in 1997 by the Oklahoma Climatological Survey (OK-First)…

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?…

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…

Albedic Meanderings

Guest Post by Willis Eschenbach I’ve been considering the nature of the relationship between the albedo and temperature. I have hypothesized elsewhere that variations in tropical cloud albedo are one…

Arctic Albedo Variations

Guest Post by Willis Eschenbach Anthony has just posted the results from a “Press Session” at the AGU conference. In it the authors make two claims of interest. The first…

The 'strawman' albedo effect

From ETH Zurich , something that actually makes sense. Straw albedo mitigates extreme heat Wheat fields are often tilled immediately after the crop is harvested, removing the light-coloured stubble and…

How Much Sunlight Actually Enters The System?

Guest Post by Willis Eschenbach There’s a new study in PNAS, entitled “Observational determination of albedo decrease caused by vanishing Arctic sea ice” by Pistone et al. Let me start…

New PNAS paper claims Arctic planetary albedo dropped significantly, yet recent CERES data shows no significant change

From PNAS: Direct satellite observation reveals that the Arctic planetary albedo, a measure of reflectiveness, decreased from 0.52 to 0.48 between 1979 and 2011, a change in albedo that corresponds…

The Thermostatic Throttle

Guest Post by Willis Eschenbach I have theorized that the reflective nature of the tropical clouds, in particular those of the inter-tropical convergence zone (ITCZ) just above the equator, functions…

Weekly Area of Snow Extent

Guest Post by Willis Eschenbach I got to thinking about snow the other day. It was occasioned by my look at the correlation (both positive and negative) of temperature and…
