That’s where I would be alarmed. Outside of the cold season, highs, lows, everything has made a steady climb of anywhere from 3-5 degrees for the most part. UHI affects lows more than highs, and DTW is nearly 20 miles from downtown, yet the daily highs in July and August have increased by about 5 degrees over the last century. I thought for a minute that my use of the word “catastrophic” was extremist, but now that I see the data, I stand by my use of that word, because the data affirms it.
