Urban heat loss 'major influence on climate change', concludes OU study

A study led by The Open University has concluded that man-made heat loss is one of the main contributing factors to national temperature variations.

Published in the American Geophysical Union (AGU)  journal, Earth’s Future, and developed in collaboration with the University of Edinburgh, ‘From Urban to National Heat Island’ has established a strong correlation between the expansion of urban infrastructure and the urban landscapes of a nation, and the general increase in temperatures.

Senior Research Fellow at The Open University and co-author of the study, Dr John Murray, said:

“Heat output has until now been largely ignored by climate prediction models. This study shows that man-made heat loss from buildings, industry and transport can have a major influence on climate change. 89% of Britain’s temperature variation alone* in the past 50 years is the result of man-made heat.

“Governments have to consider their overall energy consumption if they want to successfully combat climate change.”
