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 [...]

Sudden Changes in Ocean Currents Warmed Arctic, Cooled Antarctic in Past

Abrupt changes in ocean currents – and not greenhouse gases – were responsible for sudden warming of the Arctic and for sudden cooling in the Antarctic at different times in the past, according to two recent research studies. The Antarctic cooling marked the genesis of the now massive Antarctic ice sheet. The [...]

Evidence That Antarctica Is Cooling, Not Warming

This article was originally published at Science Under Attack. Melting due to climate change of the Antarctic and Greenland ice sheets has led to widespread panic about the future impact of global warming. But, as we’ll see in this and a subsequent post, Antarctica may not be warming overall, while the rate of ice loss [...]
