Spencer: Global Urban Heat Island Effect Study – An Update

by Roy W. Spencer, Ph. D. This is an update to my previous posts [here and here on WUWT] describing a new technique for estimating the average amount of urban heat island (UHI) warming accompanying an increase in population density. The analysis is based upon 4x per day temperature observations in the NOAA International Surface…

Urban Heat Island Influence Inadequately Considered in Climate Research

Guest Opinion: Dr. Tim Ball The Intergovernmental Panel on Climate Change (IPCC) deliberately limited climate science to focus on CO2 and temperature. The United Nations Framework Convention on Climate Change (UNFCCC) directed them only to consider human causes of climate change. They used this to narrow the focus of all variables that create the climate…

Surprise: Cold wave reveals potential benefits of urban heat islands

From the PRINCETON UNIVERSITY, ENGINEERING SCHOOL and the “UHI is good for something” department. Still, it’s not a good place to measure climate change. The concrete and asphalt that make city summers brutally hot might not be a bad thing during winter’s deep freeze. Researchers from Princeton University have found that the urban heat island…

China's Urban Heat Island Problem

How does urban-induced warming in Beijing interact with air temperature in summer? INSTITUTE OF ATMOSPHERIC PHYSICS, CHINESE ACADEMY OF SCIENCES Beijing has undergone several important urbanization development stages since late 1978. Linked with urbanization, the so-called “urban heat island effect” is a key problem caused by urban land expansion. Such changes in air temperature in…

Define Irony: Photovoltaic Heat Island Effect

Guest post by David Middleton From the Department of All Things Ironic… Solar panels, while they mitigate the effects of global warming by replacing fossil fuels, can add heat in the locations where they are installed, reports a team of University of Arizona researchers. At first blush, the experimental results, published Thursday in Nature Science Reports,…
