The Noble Corruption Of Climate Science 

H/T The Global Warming Policy Forum (GWPF)
Is IPCC-oriented climate science running out of road in terms of credibility, when measured against reality?

This is a story of climate science, tracing from its enthusiastic beginnings as a small field – warning of a global threat – to its rich and increasingly desperate present, writes Larry Kummer @ Fabius Maximus.

It is a long story, with a climax at the end.

The climate change campaign hits a dead end

On 24 June 1988, James Hansen’s testimony to the Senate began the campaign to fight anthropogenic global warming. During the following 31 years we have heard increasingly dire forecasts of doom.

Some describe the distant future, beyond any reasonable forecasting horizon (due to both technical and social uncertainties). Some describe the near future. Many attribute almost all current extreme weather to our emissions of greenhouse gases (GHG) – using impossible to validate methods.

Karl Popper said that successful predictions, especially of the unexpected, were the gold standard of science (see here). That is a problem for climate activists.

The Earth has been warming since the mid-19th century, when the Little Ice Age ended. The rate of warming in the past four decades (since 1977) is roughly the same as that during the four decades up to 1945. Anthropogenic GHG became a major factor only after WWII.

So warming has occurred as predicted, but a naive forecast (without considering GHG) would have also predicted warming. There are explanations for this, but it makes model validation difficult (perhaps why it is seldom attempted: see links in section f in the For More Info section of this post).

Worse, the weather has not cooperated. Major hurricanes avoided America for 11 years, ending in 2017. Warming slowed during what climate scientists called the “pause” or “hiatus” (see links about its causes). And most forms of extreme weather have no obvious increasing trend.

So surveys show little public support in America for expensive measures to fight climate change.

Activists grow desperate.

– sooner than you think.”

Activists responded to the uncooperative weather by making ever-more dire predictions (many of which have passed their due date and been proven false).

All extreme weather was “climate change.” They made more vivid propaganda (e.g., the 10:10 video, showing a teacher exploding the heads of students who do not accept her propaganda). They increased the volume of their claims, with more 2-minute hate sessions for dissenters (with lies about even eminent climate scientists).

The long-term effects of this are (hopefully) small, since these fear barrages have been the Left’s go-to tactic since the 1960s (see some classics of the genre).
