As the mercury ticked upward in Portland, Ore., last month, I braced for my apartment to become unbearable.
Normally, my un-air-conditioned basement unit would be fine for the Pacific Northwest’s temperate summers. But these are not normal times.
Climate change has lengthened and intensified heat waves, pushing temperatures to unheard-of extremes. In Portland, a new all-time high was set three days in a row: First, 108 degrees Fahrenheit. Then 113 degrees. Then 116.
To my astonishment, the apartment stayed tolerable all weekend. The tile floors seemed to emanate coolness. The greenery surrounding my windows blocked direct sunlight and helped bring down the temperature of the outside air. I didn’t have a thermometer, but my guess is that the temperature inside never got above 80 degrees.
