Isn the urban heat island effect (that elevates temperatures in large cities relative to rural areas) responsible for the measured increase in global temperature?
There is no urban heat island effect in the oceans, which cover nearly 3/4 of Earth’s surface, yet sea surface and deep ocean temperatures are also increasing, consistent with what’s occurring on land. Thanks to Scripps researchers Jeff Severinghaus, Richard Somerville, and Dave Pierce for providing answers to these questions.
