Since the mid-19th century the earths temperature has risen by just over half a degree Celsius. But this warming began long before cars and planes were even invented. Whats more, most of the rise in temperature occurred before 1940, during a period when industrial production was relatively insignificant. After Second World War, during the post-war economic boom, temperatures in theory should have shot up – but they didnt. They fell – not for one or two years – for four decades. In fact, paradoxically, it wasnt until the world economic recession in the 1970s that they stopped falling.

[Comment 43: The reference to cars and planes is misleading – they are not relevant here, because the early growth of CO2 emissions was due to burning of coal for heating, industrial activity and electricity generation.

The narrator continues to misrepresent global warming theory (see also Comment 40, page 33): by claiming that industrial growth can be used to predict temperature change.

His concerns would be justified if the theory actually did link industrial growth to instantaneous climate change. However, not only are industrial growth levels not directly linked to human greenhouse gas emission levels (see Comment 40, page 33), but in addition, greenhouse gas levels are not linked by the theory to instantaneous temperature changes.

There are many factors affecting climate in addition to greenhouse gas levels (see Comment 55, page 50 and the 2001 IPCC report at: The cooling period post-WWII, and the subsequent warming, is consistent with greenhouse warming theory, and is reproduced in all recent climate models (see [IPCC]). The mild cooling period post-WWII (which was greatly exaggerated in the documentarys graph, see Comment 42, page 35) has been shown to have been due to sulphate aerosol emissions. Once sulphate emissions were controlled as a consequence of air quality regulation in the 1970s, the warming impact of the greenhouse gases took over (see Realclimate:

Furthermore, the suggestion that global temperatures should be rising and falling in immediate tandem with the emissions of greenhouse gas neglects the thermal lag in the climate system. This lag is driven largely by the oceans, which are so large that it takes centuries for them to warm up (see [IPCC]). The film makers actually make reference to this memory of the oceans later on in the programme (see Carl Wunsch, page 49), but disregard it at this point in the film. This is again a clear misrepresentation by the film makers of the theory of greenhouse warming.]
