Grassroots Climate Change Movement Ignores Actual Evidence

Earth Day 2019 is marked by the recent launch of several grassroots organizations whose ostensible aim is to combat climate change. The crusades include the UK’s Extinction Rebellion, the Swedish WeDontHaveTime, and the pied-piper-like campaign sparked by striking Swedish schoolgirl Greta Thunberg. What’s most disturbing about them all is not their intentions or methods, but their ignorance and their disregard of scientific evidence.

Common to the entire movement is the delusional belief that climate Armageddon is imminent – a mere 12 years away, according to U.S. congresswoman Alexandria Ocasio-Cortez. The WeDontHaveTime manifesto declares that “climate change is killing us” and that we’re already experiencing catastrophe. Trumpets Extinction Rebellion: “The science is clear … we are in a life or death situation … ,” a sentiment echoed by the Sunrise Movement in the U.S. And a proclamation of the youth climate strikers insists that “The climate crisis … is the biggest threat in human history.”

But despite the climate hysteria, these activists show almost no knowledge of the science that supposedly underlies their doomsday claims. Instead, they resort to logically fallacious appeals to authority. Apart from the UN’s IPCC (Intergovernmental Panel on Climate Change), which is as much a political body as a scientific one, the authorities include the former head of NASA’s Goddard Institute for Space Studies, James Hansen – known for his hype on global warming – and the UK Met Office, an agency with a dismal track record of predicting even the coming season’s weather.

Among numerous mistaken assertions by the would-be crusaders is the constant drumbeat of extreme weather events attributed to human emissions of greenhouse gases. The sadly uninformed protesters seem completely unaware that anomalous weather has been part of the earth’s climate from ancient times, long before industrialization bolstered the CO2 level in the atmosphere. They don’t bother to check the actual evidence that reveals no long-term trend whatsoever in hurricanes, heat waves, floods, droughts and wildfires in more than 100 years. Linking weather extremes to global warming or CO2 is empty-headed ignorance.

Another fallacy is that the huge Antarctic ice sheet, containing about 90% of the freshwater ice on the earth’s surface, is losing ice and causing sea-level rise to accelerate. But while it’s true that glaciers in West Antarctica and the Antarctic Peninsula are thinning, there’s evidence, albeit controversial, that the ice loss is outweighed by new ice formation in East Antarctica from warming-enhanced snowfall. The much smaller Greenland ice sheet is indeed losing ice by melting, but not at an alarming rate.

The cluelessness of the climate change movement is also exemplified by its embrace of false predictions of the future, such as the claim that climate change will cause shortfalls in food production. If anything, exactly the reverse is true. Higher temperatures and the fertilizing effect of CO2, which helps plants grow, boost crop yields and make plants more resistant to drought.

 Participation in the movement runs in the hundreds of thousands around the world, especially among school climate strikers. The eco-anarchist Extinction Rebellion, formed last year, promotes acts of nonviolent civil disobedience to achieve its goals, harking back to “Ban the Bomb” and US civil rights protests of the 1950s and 1960s. To “save the planet”, the organization is calling for greenhouse gas emissions to be reduced to net zero as soon as 2025.

The newly created WeDontHaveTime subscribes to the widely held political, but unscientific belief that climate change is an existential crisis, and that catastrophe lurks around the corner. Its particular focus is on building a global social media network dedicated to climate change, with the initial phase being launched today, April 22.

The school strike for climate has similar aims, to be achieved by children around the globe playing hooky from school. An estimated total of more than a million pupils in 125 countries demonstrated in strikes on March 15.

The movement’s lack of scientific knowledge extends to the origin of CO2 emissions as well. Extinction Rebellion and WeDontHaveTime, at least, appear oblivious to the fact that the lion’s share of the world’s CO2 emissions comes from China and India alone – 34% in 2019, by preliminary estimates, and increasing yearly. If the climate change catastrophists were really serious about their objectives, they’d be directing their efforts against the governments of these two countries instead of wasting time on the west.
