May 6, 2020. After a cold winter, a shift in weather patterns unleashed a blast of early summer heat across Alaska. An aerial shot of snow-covered mountains.
 
Text, On May 9, 2020, temperatures in Anchorage hit 69 degrees Fahrenheit, just one degree shy of the record.
 
With mountains, glaciers and permafrost, spring and summer heat can thaw soils and cause landslides.
 
This is probably what happened on Yudi Peak, a mountain near Anchorage. An arrow points to a mountain peak near the top of the photo and labels it Yudi Peak.
 
Text, In early May, a landslide sent rocky debris sliding down the snow-topped mountain. An arrow points to a dark slope down the mountain and labels it Landslide.
 
Text, Large landslides are common during the spring in Alaska.
 
We travel to the right of the landslide. Text, Scientists think that climate change is driving an increase in both the size and frequency of landslides.
