«One of the main outcomes of this study is that older faunas, linked to environments that were disappearing due to increased aridity at the time, were displaced to the north surviving temporally in local refugia with more humid conditions, particularly in the region of Catalonia and the South of France» adds Manuel Hernández Fernández, professor at Universidad Complutense de Madrid and senior author of the study.

According to one study that looked at eight fuel aridity metrics in the Western U.S. and modeled climate change's effects on them, human - caused climate change accounted for about 55 percent of the observed increases in fuel aridity between 1979 and 2015 (Figure 6), and added an estimated 4.2 million hectares of forest fire area between 1984 and 2015.7 Based on all eight metrics, the Western U.S. experienced an average of 9 additional days per year of high fire potential due to climate change between 2000 and 2015, a 50 percent increase from the baseline of 17 days per year when looking back to 1979.

That said, the overall trend is clear: with fuel aridity increasing in the western U.S. due in part to human - caused climate change, the authors project that both burned area and burn severity will continue to increase under climate change.
