{"Image ImageDescription": "DEER LODGE, MONTANA - SEPTEMBER 12: Dallis Hunter, owner of Juice Custom Cutting, looks over a stack of mountain pine beetle-killed pine logs at his outdoor saw mill September 12, 2019 near Deer Lodge, Montana. Hunter specializes in cutting timber that has been killed by the mountain pine beetle, nicknamed 'blue pine' because of the fungus carried by the insect that turns the wood a bluish hue. According to the 2017 Montana Climate Assessment, the annual average temperatures in the state has increased 2.5 degrees Fahrenheit since 1950 and is projected to increase by approximately 3.0 to 7.0 degrees by mid-century. As climate change makes summers hotter and drier in the Northern Rockies, forests are threatened with increasing wildfire activity, deadly pathogens and insect infestations, including the mountain pine beetle outbreak. Although the number of new trees infested each year by the pine beetle has reduced since the height of the outbreak around 2012, the insects have killed more than six million acres of forest across Montana since 2000.
