Tim Dickinson paints this picture in his head at the end of his article. Viewing global warming as a crisis, he argues that continued global warming intensifies drought and sets the stage for megafires, even in unlikely places like Alaska. According to Dickinson, humans are the main cause of global warming. This creates a dramatic problem, Dickinson explains, because Alaska has vast tundra that is drying out. The tundra is an important biome; it can store large amounts of carbon dioxide in the soil. When these areas burn due to drought, they release huge amounts of carbon dioxide normally hidden under snow (Dickinson). On the other hand, Peter Minorsky writes that global warming may lead to increased plant growth. Minorsky's testimony complicates Dickinson's ideas. There is even an indication of increased growth in Alaska from aerial photos from 50 years ago to today in his article. He writes that there is already "evidence that many plant species are beginning to invade formerly colder climates as global temperatures begin to rise" (Minorsky). This invasion of plant life from the poles, according to Minorsky, obscures Dickinson's Alaskan example. If there is growth, the fiery images seem to die out, or at least appear as a
