The authors modeled future global fire season severity due to climate change using the Cumulative Severity Rating, a weather-based fire danger metric, of the Canadian Forest Fire Danger Rating System.
The authors reconstructed both regional climate teleconnections (ENSO, PDO, and AMO) and historical fire occurrence using tree-ring analysis. Their objectives were to analyze the relationship between moisture variability and regional, individual and phase combinations of, ENSO, PDO, and AMO and then compare this climate variability to fire occurrence in upper elevation forests across the southwest.
The authors examined the relationship between climate and fire severity across coniferous forests of the western U.S.
The authors compared the forest composition and structure along three transects at similar latitude and elevation in the San Juan National Forest to determine if climate synchronized fire occurrence across the large regional area historically.
The authors assessed the climate conditions preceding and during a period of intense fire activity across the western U.S. in the summer of 1910. They further evaluated other large regional fire years to determine if analogous climate conditions occurred during those periods of high fire activity.
The authors tested the intermediate fire-productivity hypothesis across the world’s ecoregions that posit that fire is most common at the intermediate levels of aridity and productivity while either very arid or very productive ecosystems tend to decrease in flammability.
The authors reconstructed the fire regime of a relict unharvested stand in a remote Mexican mixed-conifer forest and compared it to a previously published fire regime data from a similar site in the Chiricahua Mountains of southeastern Arizona. The authors tested the pyroclimatic hypothesis to understand the relative influence of climate on ecologically and climatically similar sites, but with differing cultural influences.
The authors quantified the structure and composition of old-growth conifer forest stands in northwestern Mexico. They related this information to fire regime history data from Fulé et al. (2012) to determine relationships between regional climate variability, fire and forest structure since approximately 250 years ago to today.
The authors reconstructed the historical fire regime of the Colorado Plateau region over the previous 1,416 years to examine changes in the fire regime in response to climate variation, specifically periods of drought, and compare models of area burned and fire frequency in relation to climate before and after approximately 1600 CE.
The authors examined the relationship between fire frequency in ponderosa pine forests and their proximity to grassland and shrubland sites as well as the sensitivity to climate variation also related to the adjacency to these sites.
