The Story behind my Paper on the ITCZ and the Hadley Circulation

By Andy May It all began eight years ago when I read and reviewed Ronan and Michael Connolly’s first three papers on their ideas about the “molar density intersection” which…

Slicing the earth to study Cloud Fraction and VPD.

Slicing the earth’s data has revealed expected correlation of sun angle to cloud fraction, VPD, and Enthalpy and interesting correlation to land fraction.  The land fraction seems to be related…

From the Surface to Space

Advection not only moves heat over the Earth’s surface to where it can travel more easily from surface to space, but the very dry air in the counterflow of cA…

Change in Reflected Solar Electro-Magnetic Radiation During CERES Era

The misdirected demonising of CO₂ has resulted in climate models that are blind to seasonal changes in solar intensity across the hemispheres and naively embody parameterisation of ice forming and…

How CO2 both Warms and Cools our Atmosphere

Greenhouse warming in the lower atmosphere is balanced by CO2 cooling in the stratosphere. This explains why CO2 concentrations do not correlate with earth’s temperatures over millions of years!

Can Annual Irradiance = Annual Enthalpy? If So, What Does It Show About Climate Change

This mathematical exercise was done to see how close calculated irradiance would come to measured irradiance and to prove that climate models using enthalpy instead of radiation or irradiation were…

SURPRISING: scientists find ties between Earth’s oxygen and magnetic field

The study authors decided to see whether Earth’s magnetic field and atmosphere have fluctuated in ways that demonstrate a link.

BOMBSHELL: Study Reveals Climate Warming Driven by Receding Cloud Cover

If climate science were a functioning scientific discipline rather than a priesthood, this paper would trigger a major course correction. It would cast doubt on the simplistic link between CO₂…

Earth’s Energy Imbalance – Part III

This final part of the series explores the issue of regulation of Earth’s climate in light of a small, continuing imbalance between energy input from Sol, and outgoing LWIR –…

Radiation and Matter

Undoubtedly clouds act to lower Earth temperature from what it would be under a cloudless planet – an obvious negative feedback in this sense. However, from the standpoint of orthodox…

High Resolution Earth Orbital Precession relative to Climate & Weather

The daily variation in Earth’s geometric relationship with the sun correlates well with observed temperature trends and also gives some indication of weather extremes from-year-to-year.  The coming changes in Earth’s…

More Evidence on Vapor Pressure Deficit, Cloud Reduction, and Climate Change

CO2 and VPD are confounded.  To understand and manage climate change science needs to find out which one is in charge.  Man knew about CO2 and its greenhouse properties before…

Energy Imbalance Part II – An Addendum

Even if Earth’s atmosphere were more opaque than it presently is  (greater optical depth), radiation from the surface would still make its way skyward. Photons would “diffuse” through a very…

Earth’s Energy Imbalance – Part II

Just as in Part I, in Part II I find numbers applied to fundamental concepts that are small but with uncertainty estimates I cannot reconcile nor find entirely credible. The…

New Study Reveals Unexpected Decline in Ocean Evaporation Amid Rising Sea Temperatures

It’s another case where observations don’t match the script. The “warming equals wetter” narrative takes a hit when a natural factor like wind can call the shots. It’s not a…

Cloud Reduction Global Warming, CRGW 101.  A Competitive Theory to CO2 Related Global Warming

With new data and input from readers, CRGW theory has been evolving over the 7 essays already published in WUWT.  This essay suggests that cascading natural steps in CRGW theory…

Relative importance of carbon dioxide and water in the greenhouse effect: Does the tail wag the dog?

Through his analysis, Koutsoyiannis calls for a reorientation of climate research, urging the scientific community to afford greater attention to hydrology and to reconsider CO₂’s central role in climate models.…

The Geological Record of Climate Change and Why Today’s Increase in Atmospheric CO2 Is the Result of Global Warming, Not the Cause

The climate is changing, and the geological record of climate change clearly shows that (a) we live in an unusually cold climate, (b) recent warming is neither dangerous or unusual,…

Is Paleoclimate Cyclic? It’s a Mystery to Me

In about 120 million years we will finally cross the Sagittarius spiral arm. We will exit this Ice House with its periodic glacial ages and enter the next Hot House…

Not that ET!  The Terrestrial ET: EvapoTranspiration, the Unexplored Source of Climate Change

Evapotranspiration, ET, is defined as the total amount water flux evaporated into the atmosphere from surface and plant (dew) Evaporation and plant Transpiration.  ET is a term used in agriculture…
