This new study published in the Journal of Atmospheric Environment quantifies the different components of warming there, with UHI making up over half of the total warming:
On average, the total temperature increase over South Korea was about 1.37 °C; the amount of increase caused by the greenhouse effect is approximately 0.60 °C, and the amount caused by urban warming is approximately 0.77 °C.
A perfect long term urbanization experiment exists that can illustrate and test this:
The real test of this would be if North Korea has maintained a surface temperature record that could be compared. Given that they are a closed country, chances are that if it exists. getting it is close to zero. What I wouldn’t give to get it. I wonder if Phil Jones has any?

Résumé / Abstract
The quantitative values of the urban warming effect over city stations in the Korean peninsula were estimated by using the warming mode of Empirical Orthogonal Function (EOF) analysis of 55 years of temperature data, from 1954 to 2008. The estimated amount of urban warming was verified by applying the multiple linear regression equation with two independent variables: the rate of population growth and the total population. Through the multiple linear regression equation, we obtained a significance level of 0.05% and a coefficient of determination of 0.60. This means that it is somewhat liable to the estimated effects of urbanization, in spite of the settings of some supposition. The cities that show great warming due to urbanization are Daegu, Pohang, Seoul, and Incheon, which show values of about 1.35, 1.17, 1.16, and 1.10 °C, respectively. The areas that showed urban warming less than 0.2 °C are Chupungnyeong and Mokpo. On average, the total temperature increase over South Korea was about 1.37 °C; the amount of increase caused by the greenhouse effect is approximately 0.60 °C, and the amount caused by urban warming is approximately 0.77 °C.
