By Andy May Nicola Scafetta has just published a new paper in Climate Dynamics examining evidence of the urban heat island (UHI) effect (Scafetta, 2021). The paper is not paywalled and can be downloaded here. In summary, Scafetta shows that part of the recent warming shown in the HadCRUT 4 global temperature record may beContinue reading “A New Look at the Urban Heat Island Effect”

The Yin and Yang of Holocene Polar Regions
Guest post by Renee Hannon Introduction The Arctic and Antarctic regions are different and yet similar in many ways. The Arctic has ocean surrounded by land and the Antarctic is a continent surrounded by water. Both are cold, glaciated and located at Earth’s poles some 11,000 miles apart. While sea ice has been retreating inContinue reading “The Yin and Yang of Holocene Polar Regions”

Global Mean Temperature Flattens the Past
Guest post by Renee Hannon Introduction There have been recent discussions about ‘flattening the curve’ and some curves are easier to flatten than others. The Pages 2K Consortium calculates global mean temperature in a manner that flattens the long-term trend and makes present day temperatures appear warmer relative to past temperatures. Across the globe, temperatureContinue reading “Global Mean Temperature Flattens the Past”

The planet is no longer warming
By Javier We define “warming” as a positive rate of temperature change over time. According to the main hypothesis, warming since 1951 has been due almost exclusively to the increase in GHGs (greenhouse gases), of which CO2 is the most important one. The IPCC does not find anything else that has contributed to the observedContinue reading “The planet is no longer warming”

Modern Climate Wavelet Patterns
Guest Post by Renee Hannon Wavelet analyses of modern global temperature anomalies provides an excellent visualization tool of temperature signal characteristics and patterns over the past 150 years. Scafetta recognized key temperature oscillations of about 9, 20 and 60-years using power spectra of global surface temperature anomalies. There has been much discussion about the 60-yearContinue reading “Modern Climate Wavelet Patterns”

HADCRU Power and Temperature
By Andy May Generally, it is agreed that the Earth’s top-of-atmosphere (TOA) energy budget balances to within the margin of error of the estimates (see Kiehl and Trenberth, 1997). The incoming energy, after subtracting reflected energy, is thought to be roughly 239 W/m2 which matches, within the margin of error, the outgoing energy of roughlyContinue reading “HADCRU Power and Temperature”
