As the Biden administration and governments worldwide make massive commitments to rapidly decarbonize the global economy, the persistent effort to silence climate change skeptics is intensifying – and the critics keep pushing back.
This summer the International Monetary Fund summarily canceled a presentation by John Clauser, a Nobel Prize-winning physicist who publicly disavows the existence of a climate “crisis.” The head of the nonprofit with which Clauser is affiliated, the CO2 Coalition, has said he and other members have been delisted from LinkedIn for their dissident views.
Meanwhile, a top academic journal retracted published research doubting a climate emergency after negative coverage in legacy media. The move was decried by another prominent climate dissenter, Roger Pielke Jr., as “one of the most egregious failures of scientific publishing that I have seen” – criticism muffled because the academic says he has been blocked on Twitter (now X) by reporters on the climate beat.
In response last month, more than 1,600 scientists, among them two Nobel physics laureates, Clauser and Ivar Giaever of Norway, signed a declaration stating that there is no climate emergency, and that climate advocacy has devolved into mass hysteria. The skeptics say the radical transformation of entire societies is marching forth without a full debate, based on dubious scientific claims amplified by knee-jerk journalism.
• Global temperatures are increasing incrementally, and have been for centuries, but the degree of human influence is uncertain or negligible. Climate skeptics themselves don’t agree on how much humans are contributing to global warming by burning fossil fuels, and how much is caused by natural variability from El Niño and other cycles that can take centuries to play out. “The real question is not whether the globe has warmed recently,” writes Koonin, “but rather to what extent this warming is being caused by humans.”
• Rapidly replacing fossil fuels with renewables and electricity by mid-century would be economically risky and may have a negligible effect on global warming. Some say mitigation decrees – such as phasing out the combustion engine and banning gas stoves – are not likely to prevent climate change because humans play a minor role in global climate trends. Others say mitigation is necessary but won’t happen without capable replacement technologies. It’s unrealistic, they say, to force societies to rely on intermittent energy from wind and solar, or wager the future on technologies that are still in experimental stages.
• The global political push to kill the fossil fuel industry to get to “net zero” and “carbon neutrality” by 2050, as advocated by the United Nations and the Biden administration, will erase millions of jobs and raise energy costs, leading to a prolonged economic depression and political instability. The result would be that developing regions will pay the highest price, while the biggest polluters (China and India) and hostile nations (like Russia and Iran) will simply ignore the net-zero mandate. This could be a case where the cure could be worse than the disease.
• Despite the common refrain in the media, there is no evidence that a gradually warming planet is affecting the frequency or intensity of hurricanes, storms, droughts, rainfall, or other weather events. The United Nations’ Intergovernmental Panel on Climate Change has expressed low confidence such weather events can be linked to human activities. Still, “it is a fertile field for cherry pickers,” notes Pielke.
