‘Waste heat’ from big cities affects temperatures for thousands of miles, says study

Cities affect temperatures for thousands of miles.

Large cities may be affecting the weather of cities more than 1,000 miles away. That is the conclusion reached by scientists from Scripps Institution of Oceanography, Florida State University and the National Center for Atmospheric Research, according to a news release from the University Corporation for Atmospheric Research.

In a new study that reveals the level to which human activities are affecting the atmosphere, climate scientists have concluded that the heat created by everyday activities in major cities changes the character of the jet stream and other major atmospheric systems. These changes can affect temperatures across thousands of miles, warming some areas and cooling others.
