SWELTERING CITY: New models suggest that climate change will cause average temperatures in cities to rise; cooler nights will become less frequent.

Cities were already known to retain more heat than the rural environments that surround them, but new modeling from researchers in the United Kingdom now suggests that urban areas are also more sensitive to changes in climate. Furthermore, they will experience greater increases in average temperature with rises in atmospheric carbon dioxide, and the cooling effects of night will become more of a memory than a reality.
Meanwhile, Washington, D.C. -- where Congress is debating over whether to pass a climate bill -- is getting a memorable preview of what new computer models are predicting. Last week's temperatures broke a 100-year record, and forecasters expect this June will be the hottest ever recorded in the area.
