According to the Arctic Report Card 2022, climate-driven events like Typhoon Merbok, which flooded Western and northern Alaska communities in September, show how the north is growing warmer and wetter.
Typhoon Merbok flooded Western and northern Alaska communities in September, damaging homes, roads, subsistence resources and cultural sites. A typhoon, as well as increasing wildfires and rain, are not what most associate with the Arctic — at least not yet.however, these climate-driven events show how the north is growing warmer and wetter.
“My community is one of many across the Arctic that is bearing the brunt of climate change impacts,” said Schaeffer, director of Climate Initiatives for the Alaska Native Tribal Health Consortium and co-author of the 2022 Arctic Report Card. “Our homes, livelihoods and physical safety are threatened by the rapid melting ice, thawing permafrost, increasing heat, wildfires.
When sea ice melts due to warming, more solar heat is absorbed by the exposed ocean surface and, in turn, the warmer ocean melts more sea ice. Thus, the warming cycle intensifies.This year was also the second wettest year since 1950, the Arctic Report Card showed. Increasing wildfires is another consequence of changes in climate patterns in the Arctic, the researchers said. While heavy rains could put out wildfires, more precipitation also goes hand in hand with temperature increase and with higher evaporation, said Walsh. In this way, more rain does not guarantee a wetter landscape, and in fact, “Alaska is more likely to become drier for periods in the summer,” he said.
