A reconfiguration of plate tectonics reduced volcanic degassing to a minimum during the Sturtian glaciation period. This is why it was such an extreme climate event that lasted for 57 million years.
Historically low volcanic carbon dioxide emissions were aided by weathering of a large pile of volcanic rocks in what is now Canada. This process absorbed atmospheric carbon dioxide and caused the planet to be blanketed in ice from poles to equator, with temperatures plunging during this time.
The Sturtian glaciation, also known as the Franklin large igneous province (LIP), was a period of extreme ice-age climate that lasted from 717 to 660 million years ago. This era is regarded as one of the most severe intervals of icehouse climate in Earth's history.

The Sturtian glaciation occurred before the dinosaurs and complex plant life on land existed, making it a fascinating period for scientists to study.

Deception
(50%)
The article is deceptive in several ways. Firstly, the author claims that historically low volcanic carbon dioxide emissions were aided by weathering of a large pile of volcanic rocks in what is now Canada; however, this statement contradicts itself as it implies that both factors contributed to the ice age. Secondly, the article states that all-time low levels of volcanic carbon dioxide in the atmosphere caused an extreme ice age on Earth for 57 million years. However, there are no sources cited or evidence provided to support this claim. Thirdly, the author uses a plate tectonic model and geological evidence from South Australia to identify the most likely causes of an extreme ice-age climate on Earth; however, they do not disclose any other factors that may have contributed to this climate change.

Deception
(50%)
The article is deceptive in that it presents a study as conclusive evidence for an extreme ice-age climate when the study only provides evidence for historically low volcanic carbon dioxide emissions and weathering of a large pile of volcanic rocks. The article also implies that this was the sole cause of the Sturtian glaciation, which is not supported by other research.
The article states that 'historically low volcanic carbon dioxide emissions' caused the ice age but does not provide any evidence for this claim.
The article implies that weathering was solely responsible for absorbing atmospheric carbon dioxide, which is also unsupported by other research.

The article discusses the cause of an extreme ice-age climate in Earth's history more than 700 million years ago. The author uses plate tectonic modelling to determine that historically low volcanic carbon dioxide emissions and weathering of a large pile of volcanic rocks in what is now Canada were the causes. This information supports the built-in thermostat theory, which states that Earth's temperature prevents it from getting stuck in overheating mode. The article also shows how sensitive global climate is to atmospheric carbon concentration.

Deception
(50%)
The article is deceptive because it implies that volcanic activity caused the extreme ice age without providing any evidence or sources to support this claim. It also suggests that CO2 levels were below 200 ppm when they are not, and uses emotional language like 'double whammy' and 'the most extreme interval of icehouse climate in Earth's historyƩ to manipulate the reader's emotions. The article also does not mention any peer-reviewed studies or sources for its claims, which raises questions about its credibility and reliability.
The article says that 'a large mass of volcanic silicate rocks that existed in modern day Canada began to get weatherbeaten, a process that helped suck even more CO2 out of the air. This is a lie by omission because it does not provide any sources or evidence for this claim, and it contradicts other studies that suggest volcanic eruptions actually increased CO2 levels during this period.
The article says that 'there were no multicellular animals or land plants on Earth when the ice age started. This is a lie by omission because it ignores the fact that there was still some life on Earth, such as microbes and algae, and that these organisms could have also affected CO2 levels.
The article does not mention any peer-reviewed studies or sources for its claims, which raises questions about its credibility and reliability.
The article says that 'geology ruled climate at this time'. This is a fallacy because it implies that geological processes were the only factors influencing climate, when in fact there could have been other factors such as orbital changes or atmospheric chemistry.
The article says that 'their findings might offer a way to look at Earth's future temperature changes. This is an example of false hope because it suggests that geological processes are the main driver of climate change, when in fact human activity and other factors are more likely to be responsible.
The article says that 'human-induced climate change is happening at a pace 10 times faster than we have seen before. This is an example of false comparison because it uses emotional language like 'extremely slow' to downplay the urgency and severity of human-induced climate change, when in fact the evidence shows that both natural and anthropogenic factors are contributing to rapid changes in Earth's climate system.
The article says that 'shifting tectonic plates that slowed volcanic activity' caused the extreme ice age. This is a lie by omission because it does not explain how or why these shifts in tectonics affected CO2 levels, and it ignores other possible factors such as erosion of volcanic rocks. It also implies that volcanic activity was the main cause of the ice age without providing any evidence or sources to support this claim.
The article does not provide any sources or citations for its claims, which raises questions about its credibility and reliability. It also uses emotional language like 'double whammy' and 'the most extreme interval of icehouse climate in Earth's historyƩ to manipulate the reader's emotions without providing any evidence or context.
The article says that 'the Sturtian ice age kicked in due to a double whammy: a plate tectonic reorganization brought volcanic degassing to a minimum, while simultaneously a continental volcanic province in Canada started eroding away, consuming atmospheric CO2. This is an example of false dilemma because it presents this as the only possible explanation for the ice age, when there could have been other factors or interactions involved.

The article presents a theory that low volcanic activity and the formation of new ocean crust led to an extreme ice age on Earth. The author uses examples from geological studies to support their claim. However, there are some fallacies present in the article.

The article discusses the link between volcanic activity and atmospheric carbon dioxide levels. The author suggests that a lack of CO2 in Earth's atmosphere millions of years ago led to an extreme ice age known as Sturtian glaciation. However, the author also acknowledges that another set of scientists previously believed that this ice age was formed by volcanic activity and not a lack thereof. The article suggests that geological processes ruled climate at this time, which could offer a way to look at Earth's future temperature changes.
