\"\"<\/figure>\n\n\n\n

Last year, Chris Packham hosted a five-part series on the BBC called Earth<\/em><\/a>, which compared a mass extinction event 252 million years ago to the small rise in atmospheric carbon dioxide seen in the last 150 years. He said he hoped the \u201cterror factor<\/a>\u201d generated by his programme would \u201cspur us to do something about the environment crisis\u201d. But as we shall see, the only terror factor is having to sit through an hour-long film consisting of cherry-picked science data and unproven assertions in the hope of persuading us that the increase in global temperatures in the last 150 years or so is comparable to the rise in temperatures over a considerable swath of geological time. Great play was made of a 12\u00b0C rise in average global temperatures 252 million years ago as CO2 <\/sub>levels started to rise, although Packham fails to report that CO2<\/sub> levels were already at least four times higher back then than in modern times. The \u2018science\u2019 that Packham cloaks himself with on every occasion is hardly served by terrorising the viewer with what is little more than a highly personal political message.<\/p>\n\n\n\n

Think of all that suffering and wastage, he says about the fourth great mass extinction. I don\u2019t think we want a comparable extinction to the one that happened 252 million years ago on our conscience, he adds. Of course, Packham is not the first person to politicise the end-Permian extinction when most plant and animal life disappeared to be replaced eventually with what became known as the age of the dinosaurs. As we can see from the graph below, even though that extinction event coincided with an uptick in CO2<\/sub>\u00a0levels, the general trend over a 600-million-year period was downwards ending in the near denudation currently experienced today. But scientists note that the rise started some time before the extinction event, with most of the Permian characterised by very low levels of CO2.<\/sub><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

It is obvious why the three other great extinctions are of little interest to modern day climate alarmists. The Ordovician extinction 445 million years ago occurred when CO2 <\/sub>levels were 12 times higher than today, the Devonian wipe-out happen 372 millions ago when CO2<\/sub> levels were falling, while the later Triassic\/Jurassic event 201 million years ago occurred at a time of stable CO2<\/sub>. Hard to see a pattern there suggesting rising CO2 <\/sub>levels equals a mass extinction event. The disappearance of the dinosaurs 66 million years ago is generally attributed to the impact of a giant meteorite, while the current sixth mass extinction exists only inside the head of the Swedish doom goblin, and need not detain us at this point.<\/p>\n\n\n\n

Since Packham was essentially making a BBC political film promoting Net Zero, he inevitably started with the fixed view that all our current environmental problems are the fault of CO2<\/sub>. An intense period of volcanic eruptions that led to huge coal deposits catching fire increased CO2<\/sub>\u00a0levels and almost instantly sent temperatures soaring at the end of the Permian period. About 20 million years of rain subsequently followed, he observed, taking some of the CO2<\/sub>\u00a0out of the atmosphere and order it seems was restored. Certainly, CO2<\/sub>\u00a0resumed a small descent but levels remained almost as high, or for some periods higher, as those at the end of the Permian period for another 120 million years. Packham does not provide an explanation of what happened to the average global temperature at this time.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The graph above shows why he avoided the subject. Temperatures did rise at the end of the Permian period after a long decline, but only as far as previous highs recorded 200 million years earlier. They then stayed at those levels for most of the next 200 million years, throughout the age of the dinosaurs. Helped by the increased levels of CO2<\/sub>, this is considered one of the most verdant periods in Earth\u2019s history.<\/p>\n\n\n\n

Is it likely that volcanic eruptions triggered the substantial rise in temperature around 252 million years ago, as Packham claims? In a paper published in 2022, a group of European scientists said their data showed seawater temperature began to rise at least 300,000 years before<\/a> the main volcanic eruptions. \u201cGradual warming by approximately 12\u00b0C was probably responsible for initial environmental degradation that eventually culminated in the global and Permian extinction,\u201d they wrote. The scientists reviewed much of the published evidence and concluded \u201ca temporal link between volcanic activity, environmental changes and biological impacts remains controversial\u201d.<\/p>\n\n\n\n

Carbon dioxide, of course, is the main cause of global warming in Packham\u2019s world. Promoting his film to like-minded activists at the Guardian,<\/em> he said it was the \u201curgency that makes me despair\u201d. As we can see, this \u201cdespair\u201d is the result of comparing events hundreds of millions of years ago with a small temperature rise in the past 150 years or so of around 1\u00b0C \u2013 and this after a short-term period of global cooling. You can of course argue about all this, but it is a bit rich to claim the science of recent global warming is \u2018settled\u2019 and refuse to debate anyone who disagrees with you.<\/p>\n\n\n\n

From such a shaky base, Packham claims we\u2019re all becoming far too complacent about pumping CO2<\/sub> into the atmosphere. \u201cIt\u2019s an experiment we have been running for over 100 years,\u201d he told the Guardian<\/em>. \u201cThe more the CO2<\/sub>, the more the heat is locked in and the hotter our Earth becomes.\u201d But if Packham really believes that, how does he explain those geological periods when temperatures fall as CO2<\/sub> levels rise? And if a rise in temperatures and mass extinction is inevitable when CO2<\/sub> rises, how does that work in the current period when CO2<\/sub> levels are as low as they\u2019ve ever been?<\/p>\n\n\n\n

Could it be that the end-Permian extinction was actually caused by CO2<\/sub> starvation? During the Permian, it was the first time in Earth\u2019s history that CO2<\/sub> concentrations fell below 1,000 parts per million, perhaps as dangerously low as 200 ppm at some points. This may well have started to stress plant life since 1,000 ppm is a concentration that supports maximum photosynthesis productivity. This is the view of Jim Steele<\/a>, Director Emeritus of San Francisco State University\u2019s Sierra Nevada Field Campus. In a recent paper, he noted that many researchers have pointed to competition between different plant species for declining CO2 <\/sub>during the Permian period. This was said to result in \u201cseverely reduced photosynthesis, the collapse of primary productivity and a significant malfunction of the global food webs\u201d.<\/p>\n\n\n\n

The truth is that the scientific jury is still out and the \u2018science\u2019, as with most climate science, is unsettled. Perhaps inadvertently, Packham has simply drawn attention to all the observational evidence that suggests CO2<\/sub>, the gas of life, \u2018saturates<\/a>\u2019 at around 300-400 ppm, and its warming effect is greatly diminished beyond that concentration. But \u201cfear is motivating\u201d he claims, and in the BBC he seems to have a compliant megaphone for whatever green propaganda he cares to promote.<\/p>\n\n\n\n
