One cause of the intensification of these events is the spread of Dendroctonus ponderosae, which introduces a blue-stain fungus to protect its larvae and block nutrients from flowing within the host.

The invasive Bromus tectorum, which creates a bad feedback loop of these events, has been shown to increase biomass by around two grams per plant for every ten ppm increase in atmospheric carbon dioxide. It is unclear whether these events will increase in frequency in the long run, as the climatic changes favorable to them may be offset by an overall reduction in available (*) biomass. These events may themselves affect the climate, in part by releasing carbon dioxide previously stored by peat bogs. For 10 points, what are these events that affected Yellowstone in 1988 and killed 19 people in Arizona in 2013, in which large swathes of land are burned?
