Mainstream gets extreme weather wrong again

"If it [a scientific hypothesis] disagrees with experiment, it’s WRONG." – Nobel Prize winner Richard Feynman The popular but mistaken belief that weather extremes are worsening be­cause of climate change has been bolstered in recent years by ever increasing hype in nearly all mainstream media coverage of extreme events, despite a [...]

Humlum in Clintel Lecture: look at ocean surface temperatures

"If it [a scientific hypothesis] disagrees with experiment, it’s WRONG." – Nobel Prize winner Richard Feynman According to the climate change narrative, modern global warming is largely the result of human emissions of CO2 into the atmosphere. But a recent lecture questioned that assertion with an important observation suggesting that ocean surface temperatures, not [...]

Climate models unable to reproduce ocean surface temperatures

"If it [a scientific hypothesis] disagrees with experiment, it’s WRONG." – Nobel Prize winner Richard Feynman An earlier post of mine described how a group of prestigious U.S. climate scientists recently admitted that some climate models run too hot, greatly exaggerating future global warming. Now another group has published a research [...]

Ocean currents may be more important than the greenhouse effect

"If it [a scientific hypothesis] disagrees with experiment, it’s WRONG." – Nobel Prize winner Richard Feynman A rather different challenge to the CO2 global warming hypothesis from the challenges discussed in my previous posts postulates that human emissions of CO2 into the atmosphere have only a minimal impact on the earth’s temperature. Instead, it [...]

The Greenhouse Effect, Revisited

"If it [a scientific hypothesis] disagrees with experiment, it’s WRONG." Nobel Prize winner Richard Feynman As a further addendum to my series of posts in 2020 and 2021 on the CO2 global warming hypothesis, this post presents another challenge to the hypothesis central to the belief that humans make a substantial contribution to [...]

No Evidence That Climate Change Is Making Droughts Any Worse

"If it [a scientific hypothesis] disagrees with experiment, it’s WRONG." – Nobel Prize winner Richard Feynman The hullabaloo in the mainstream media about the current drought in Europe, which has been exacerbated by the continent’s fourth heat wave this summer, has only amplified the voices of those who insist that climate [...]

Evidence for More Frequent and Longer Heat Waves Is Questionable

Heat wave in Paris in 2019. Originally published at the blog Science Under Attack. In a warming world, it would hardly be surprising if heat waves were becoming more common. By definition, heat waves are periods of abnormally hot weather, last­ing from days to weeks. But is this widely held belief actually [...]

Temperature extremes: it’s cold South of the Equator

"If it [a scientific hypothesis] disagrees with experiment, it’s WRONG." – Nobel Prize winner Richard Feynman While sizzling temperatures in Europe have captured the attention of the mainstream media, recent prolonged bouts of cold in the Southern Hemisphere have gone almost unnoticed. Can these simultaneous weather extremes be ascribed to climate [...]

Number of Tropical Cyclones down 13 percent last century

"If it [a scientific hypothesis] disagrees with experiment, it’s WRONG." – Nobel Prize winner Richard Feynman Despite the claims of activists and the mainstream media that climate change is making major hurricanes – such as U.S. Hurricane Harvey in 2017 or Hurricane Katrina in 2005 – more frequent and stronger, several recent [...]

Methane obsession totally unwarranted

You’ve probably heard that methane, one of the minor greenhouse gases, allegedly makes an outsized contribution to global warming. But the current obsession with methane emissions is totally unwarranted and based on a fundamental misunderstanding of basic physics. This misconception has been explained in detail by atmospheric physicists William Happer and William van [...]
