The fatal flaw of global warming

ocean and cloudsMost climate scientists accept that carbon dioxide in the atmosphere has some warming effect on Earth’s climate, but undisputed science shows that its direct effect is tiny and declines dramatically as carbon dioxide levels rise.

The climate models produce scary warming forecasts by assuming “positive feedbacks.”  This is the basis of their claims that man’s production of this harmless gas of life is pushing Earth toward an irreversible temperature tipping point.

Their main feedback assumption, expressed simply, goes like this: more carbon dioxide produces surface warming, which causes more evaporation from the oceans, which increases water vapor in the atmosphere, which increases greenhouse warming, which causes more evaporation, and so on and so on.

But observations and science tell us there are also negative feedbacks.  Heat produces evaporation, which puts more moisture into the atmosphere, which must produce more clouds, which reflect solar radiation and shade and cool the surface.  Evaporation also causes cooling of moist land and ocean surfaces and transfers latent heat into the atmosphere, where it has more chance of being radiated to space.

Then there are the wild cards.  Climate can be affected by Earth’s albedo, which depends on the cover of ice, snow, soot, vegetation, and clouds; by volcanic eruptions and bushfires producing heat, dust, and pollution; by cycles in sunspots, cosmic rays, and planetary gravitational effects; or by the restless oceans with shifting currents and oscillations such as El Niño.  The climate models have no chance of correctly forecasting the combined effect of all such variables for decades into the future.  They did not predict the global warming “pause,” and they cannot tell when/if it will end.

However, climate history tells us that Earth has a natural ability to self-correct climate extremes.  Unlike the models, whose feedbacks produce tipping points, Earth has never suffered a warm era or an ice age that lasted forever.  In fact, the life-supporting warm periods have been comparatively short.

There is a fatal flaw deep in the heart of every climate model, which a group of researchers have recently uncovered.  This is a feedback formula, which provides never-ending feedback and runaway warming.  The formula is borrowed from electronic circuitry and is not appropriate for complex dynamic systems such as Earth’s atmosphere.

The effect of this formula is dramatic – it multiplies the initial minor greenhouse warming by a factor of at least 3.  This takes their forecast warming from a doubling of CO2 from an un-alarming 1℃ to a scorching 3+℃.  It is why every one of the 73+ models runs hot.

This feedback mechanism in the climate models is the sole basis for the warming scare.

It is clear that most climate change is natural.  Earth is on a natural climate see-saw and not approaching a man-made tipping point.
