Complaint to Ofcom Regarding “The Great Global Warming Swindle”

Shaviv in his comment further suggests that because CO₂ concentrations in the past have been up to 10 times the current levels, we should therefore be sanguine about the prospect of future warming. In doing so, he is neglecting the many other factors that impact global temperature, such as orbital, solar, and geological effects (http://tinyurl.com/7r6q4). These factors are always changing, so a given CO₂ concentration level will not guarantee a specific temperature change, making Shaviv’s statement misleading in this context. More importantly, when CO₂ levels were very high in the past, there were not 6 billion people on earth, living in densely populated cities, many of them in coastal regions, that are very vulnerable to the effects of changes in climate, such as sea level rises. There have also been massive extinction events in the past, but that does not mean that any sensible policy maker would wish to risk causing another massive extinction event now.

Clark’s comment is puzzling, as CO₂ has indeed affected past climates. His use of the term “driver” refers to the lag between temperature and CO₂ changes over time; and is part of the incorrect CO₂–lag argument he makes later on – see Comment 50, page 45 for details.

Regarding Corbyn’s comment: given that CO₂ concentrations have remained stable over the last 1000 years until the industrial era (see http://tinyurl.com/2p8rr9), no one would suggest that the minor climate changes experienced during that period were associated with CO₂. Since the start of the industrial era, however, CO₂ is considered to be a primary driver of global warming (http://tinyurl.com/yu9kuu).]
