Renewable Energy 8

Which is better for the environment: renewable energies, oil, gas, coal or nuclear energy? The environmental damage caused by energy sources can be measured by their ‘footprint’ — the area required to produce a specific amount of energy. An article in Forbes lists the energy produced per unit area of major energy sources, from which […]


Shaviv and Pielke on Climate Science in 2011 9

Nir Shaviv is an astrophysicist who wrote some of the more interesting studies showing the role of Gamma Ray Flux (GRF) on climate change, now belatedly being acknowledged by the climate establishment. He gives some advice to students here: Stay away from Climate Science until you are tenured or retired! My point is that because […]


Sea level rise projections bias 13

Sea levels, recently updated with 10 new data-points, reinforce the hiatus described as a ‘pothole’ by Josh Willis of NASA’s Jet Propulsion Laboratory, Pasadena, Calif., who says you can blame the pothole on the cycle of El Niño and La Niña in the Pacific: This temporary transfer of large volumes of water from the oceans […]

Phase Shift in Spencer’s Data 21

It was shown here that the phase shift between total solar irradiance and global temperature is exactly one quarter of the solar cycle, 90 degrees, or 2.75 years. This is a prediction of the accumulation theory described here and here that shows how solar variation can account for paleo and recent temperature change. Phase shifts […]


FFT of TSI and Global Temperature 15

This is the application of the work-in-progress Fast Fourier Transform algorithm by Bart coded in R on the total solar irradiance (TSI via Lean 2000) and global temperature (HadCRU). The results show (PDF) that the atmosphere is sufficiently sensitive to variations in solar insolation for these to cause recent (post 1950) warming and paleowarming. The […]

Sinusoidal Wave in Global Temperature 60

A dynamic way of looking at global temperature is to plot it in phase space, which is usually with the position on the x axis and velocity on the y axis. Below is the phase space graph of global temperature since 1996 with temperature on the x axis and change in temperature on the y […]
