[19] In April 2024, naturalist Chris Packham referred to the blog as the "Daily Septic" in an appearance on BBC One and said it was "basically put together by a bunch of professionals with close affiliations to the fossil fuel industry."

[20] In October 2021, The Daily Sceptic published an article suggesting that Office for National Statistics (ONS) data showing an increase in the number of teenage deaths between June and September 2021 was connected to the rollout of COVID-19 vaccines in the United Kingdom.

The disinformation analysis organisation Logically noted that the complete UKHSA report cautioned against using the raw data to estimate vaccine effectiveness due to it not taking inherent biases such as "differences in risk, behaviour and testing" into account.

[22] In December 2022, The Daily Sceptic claimed that a study published in the Clinical Research in Cardiology journal showed that people who had "died suddenly" were likely killed by the COVID-19 vaccines.

The scientists behind said studies told Agence France-Presse that The Daily Sceptic had misrepresented their findings, and that the impact of fossil fuels on global warming was well-documented.

Marit-Solveig Seidenkrantz, a professor of geology and climate change at Aarhus University in Denmark, called The Daily Sceptic's article an example of "alternative facts".
