对波托马克河地区天气的最主要影响是大范围的气候模式，而不是日益严重的“热岛”效应，因此该地区的温度数据可以与全球趋势进行有效比较。然而，至少暂时，包括华盛顿特区在内的该地区已经失去了与全球气温趋势的联系。波托马克河地区天气的短期区域异常，特别是夏季高温，可能会促进美国国会就长期全球气候研究采取立法行动。然而，美国政治中心目前良好的天气状况往往会转移人们对全球气候研究的注意力，从而降低了大幅扩大研究经费和温室气体立法的可能性。
Large-scale climatic patterns, rather than a growing “heat island” effect, are the overriding influence on weather in the Potomac River area, and temperature data in the area can therefore be validly compared to global trends. At least temporarily, however, the area, which includes Washington, D.C., has lost its coupling with global temperature trends. Short-term regional anomalies in the Potomac River area's weather, especially high summer temperatures, may promote legislative action in the U.S. Congress on long-term global climate research. However, the current benign weather conditions in the political center of the United States tend to divert attention away from global climate research, diminishing the likelihood of significant expansion of research funding and greenhouse gas legislation.
