UHI May Account For Half Of Climate Warming In China

Whether the urban heat island effect is in fact warming ‘the climate’ is debatable, but in a propaganda war it can be made to seem so. In any case this needs as wide a coverage as possible, to offset at least some of the alarmist spin about supposed man-made warming that’s pushed down everyone’s throat on a daily basis.

NOT A LOT OF PEOPLE KNOW THAT

By Paul Homewood

A new study by Nicola Scafetta shows that a considerable percentage of China’s global warming from 1940 to today is due to the phenomenon of urbanization. However, the models mistakenly associated this same warming to anthropogenic forcing:

Near-surface temperature records show that China warmed by about 0.8 °C from 1950 to 2010. However, there exists an ongoing debate about whether this warming might have been partially due to urbanization bias. In fact, homogenization approaches may be inefficient in densely populated provinces that have experienced a significant urban development since the 1940s. This paper aims to complement previous research on the topic by showing that an alternative approach based on the analysis of the divergence between the minimum (Tmin) and maximum (Tmax) near-surface temperature records since the 1940s could be useful to clarify the issue because urban heat island (UHI) effects stress the warming of nocturnal temperatures…
