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…

The Earth’s Energy Imbalance: Part I

When I began this effort I expected to discover that my search for energy imbalance would find a very small number with a very large uncertainty. This is exactly what…

Soundings, Weather Balloons, and Vapor Pressure Deficit

The high VPD air mixes with passing air in the lower cloud zone (cumulus clouds altitude) and retards cloud formation somewhere.

VPD, Vapor Pressure Deficit a Correlation to Global Cloud Fraction?

This paper will explore the relationship between global VPD and global Cloud Fraction (Cover), CC.

The Effect of a Colder Solid’s Thermal Radiation on a Warmer Solid Exposed to Sunlight

It is experimentally shown that the thermal radiation from a transparent, colder solid has the capacity to influence a solid warmer than it to become even warmer, under the right…

Hunga Tonga volcano: impact on record warming

I present arguments that support the view that we are facing an extraordinary and extremely rare natural event in climate history.

Of Heat Engines: an Addendum

The atmosphere is not static. It is dynamic and it is bootstrapping its way into a deeper and deeper layer of instability.

Of Heat Engines and Refrigerators

The atmosphere is less a heat engine than a collection of many self-running refrigerators/dehumidifiers operating in different ways to carry heat largely from surface to tropopause locally and the balance…

Negligible future warming from: CO2 – CH4 – N2O

As at its current concentration atmospheric CO2 at 420 ppmv is already more than 85% saturated,  its Global warming potential is almost entirely exhausted.

Model Atmospheres

”…no one knows just how the complicated climate system of Earth’s atmosphere will respond to the small forcings [of GHGs].”

Does GHG Forcing Have Significantly Less Efficacy Than a Similar Sized Solar Forcing?

Is it possible that the Effective Radiative Forcing (ERF) of a small change in GHG forcing is a lot lower than the ERF for a similar change in solar forcing?…

Climate fearmongering reaches stratospheric heights

entitling such a paper “Exceptional stratospheric contribution to human fingerprints on atmospheric temperature” is essentially a non sequitur on the issue of global warming.

Thermosphere is Cooling, Bad for Satellites. Thermosphere is Heating, Bad for Satellites.

Thermospheric cooling, CO2 and models are proved again, bad for satellites. Thermospheric warming, it’s that damn sun and its storms, bad for satellites.

Nitrous Oxide and Climate

Nitrous oxide (N20) has now joined carbon dioxide (CO2) and methane (CH4) in the climate alarm proponents’ pantheon of anthropogenic “demon” gases.

Outside the Black Box: Back to Basics

For the anthropogenic part it’s pretty clear: with a growth to a maximum CO2-level of 560 ppm, even under a realistic ‘business as usual’ scenario [11], there is certainly no…
