Fig. 2: Fire-regime attributes in climate space.

From: Widespread exposure to altered fire regimes under 2 °C warming is projected to transform conifer forests of the Western United States

Fig. 2

The climate space of all conifer forest is shown in grey; burned conifer forest meeting statistical support criteria for this analysis are colored by the mean (a) fire rotation period (yrs), (b) vegetation productivity (NDVI), and (c) burn severity (CBI) values of all points within each hexagon. (d) Univariate histograms of burn severity data are shown for an example contemporary-future climate analog pairing. The area (grey) between empirical cumulative distribution functions (green and orange lines) is shown to visualize the earth mover’s distance in one dimension. A multivariate earth mover’s distance was calculated and is interpreted as exposure to fire-regime change.
