January 23, 2023 — The fall of 2016 ushered in a historic drought for Southeast Alaska. Hot, dry summers wreaked havoc on subsistence crops like wild berries. Warmer waters disrupted salmon hatcheries in Juneau. And in 2018, about twice as many fires burned in the Tongass as what’s typical.
By 2019, the U.S. Drought Monitor had declared an extreme drought across the region. Rick Thoman, a climate scientist with the University of Alaska Fairbanks, says dry spells are not abnormal, even in a temperate rainforest. But the drought from 2016 to 2019 was unique.
“This was a warm, dry drought. And that is very different,” he said. “Droughts from the ’50s, from the ’70s, even into the early ’80s — they were cold, dry droughts. And that matters a lot.”
Though there have been warmer droughts and drier droughts in the past, the region’s longest droughts on record have often been accompanied by below-average temperatures. With 2016, Southeast’s warmest year on record, that changed.
