As well defined turning points in response and a limit-cycle of operation are long established characteristics of relay control systems, I submit that Earth’s climate regulation is non-linear in much the way a relay controller...

I’ve been thinking about some ideas that WUWT contributor Willis Eschenbach (WE) has proposed. In particular, WE has suggested that tropical cumulus clouds and thunderstorms provide a “thermostatic mechanism” that helps...

The bottom line is that climatology is simply wrong about the magnitude of future global warming. No government should pay the slightest attention to anything it says.

Guest post by Kevin Kilty Introduction I had contemplated a contribution involving feedback diagrams, systems of equations, differential equations, and propagation of error ever since Nick Stoke’s original contribution...

By Joe Born 1. Introduction By presenting actual calculation results from a specific feedback-system example, the plots below will put some graphical meat on the verbal bones of Nick Stokes’ recent “Demystifying...

Guest post by Nick Stokes, People outside climate science seem drawn to feedback analogies for climate behaviour. Climate scientists sometimes make use of them too, although they are not part of GCMs. But it gets tangled....

It’s always the same.  A new paper adds one more magical fine-tuning-cog to the models and promises “more accurate predictions”. There are a million small cogs we can add and it takes years to show they...

… In most ways, David Evans’ alternative model is exactly the same as the conventional model. But a reconnection of one forcing, and an additional factor, can make all the difference. Finally, climate model architecture...

… The ground is not the sky Here’s a big big flaw that is easy for anyone to understand, yet has lain at the core of the climate models since at least 1984...

Yet more observations from the planet show that modelers misunderstand the water based part of the climate – on our water based planet.

Let’s be as generous as we can. The IPCC say feedbacks amplify CO2′s warming by a factor of about three. Without the amplification from positive feedback there is no crisis So being nice people, let’s assume...

From the AGU weekly highlights Composite image. Data from MODIS. Credit: National Snow and Ice Data Center. See High Resolution Image Key Points: EFA method is valuable in providing quantitative assessment of feedback Decrease...

A new brief summary of the reasoning and evidence behind the skeptics case. –Jo ——————————————— The Skeptic’s Case Who Are...

Ladies and Gentlemen this is the front line trench of modern science. If climate science is so important, and there is no time to waste, why does the system try so hard to discourage dissent (because they don’t want...

Dr Noor van Andel spoke at the Dutch Meteorological Institute (KNMI), provocatively concluding there is no observational evidence for the influence of CO2 on past or present climate...
