New paper out in Science Advances today on A guide to assessing the impacts of climate change on landscape fire. There are thousands of papers on fire and climate change, and this paper discusses how fire, its drivers, and its impacts are modeled.

Record-Breaking 2025 European Wildfires Concentrated in Northwest Iberia

Map of the Burned area in August 2025 across the northwest of the Iberian Peninsula (NW-IP; orange), highlighting megafires (> 10,000 ha; red). Scatterplot of monthly Buned Aarea versus Fire Weather Iindex in the NW Iberian Peninsula for 1985–2025. Plot of the burn selectivity in August 2025 for the NW-IP: black dots show the fraction of BA for each vegetation class. “Pinus” and “Quercus” include natural, semi-natural, naturalized and plantations of native species. The red triangles indicate the presence of each class in the study area (i.e., what fraction of that vegetation class would have burned if fires were equally affecting all vegetation classes). Black error bars are 95% confidence intervals estimated through a conservative leave-one-fire-out jackknife.

New accepted paper in Environmental Research Letters on the extent of drought determines daily area burned (DAB) in Canadian forests. This study found a strong relationship
between DAB and the spatial extent of fire-conducive weather conditions.

Ecozone burned areas between 2001 and 2023, and the fire weather thresholds for Potential Spread Days (PSDs) that were used to derive Realized Spread Day sum. The black curve is the fitted generalized additive model based on the paired percentage area burned by unit Canadian Fire Weather Index System (CFWIS) indices (grey points). The shadowed areas and the vertical line are the range and the threshold of CFWIS indices used to identify a PSD.

🔥New in IJWF:

Ohlson et al. map fine dead fuel moisture across a Colorado mixed-conifer forest using 1-h fuel samples from 80 plots. They reveal strong fine-scale spatiotemporal variability shaped by canopy, understory, and aspect.

🔗 doi.org/10.1071/WF25...

#IJWildlandFire
(a) Post-treatment forest structure and two people sampling fuels from the 0 to 1.7 m and 2.8 to 4.5 m plots within the clustered design. (b) A plot placed between two whiskers to mark the distance intervals and the strings stretched across the PVC sampling frame to denote the randomly generated 20 × 20 cm subplot for collecting the plot’s observation. Black markings on the PVC sampling frame are at 20 cm intervals to create the grid of 36 subplots. (c) Two people collecting a dead fine fuel sample into a pre-labeled and pre-weighed polyethylene resealable bag. The observation period was organized into three phases: early summer (Julian day 138–189), mid-summer (Julian day 192–236) and late summer (Julian day 243–287) for the following plots. The dashed lines on the axes depicting FMC indicate the commonly used 30% moisture of extinction threshold for dead understory forest fuels ( Rothermel et al. 1986). (a) Empirical cumulative density functions of the three distributions (early summer, mid-summer, late summer) of observed fuel moisture content. (b) Kernel density plots of the three intraseasonal period distributions. (c) Boxplots colored by intraseasonal period depicting the distribution of FMC on each observation day. The box indicates the inter-quartile range (25th to 75th percentiles). The mid-band indicates the median, and the whiskers indicate points within 1.5 times the interquartile range. Points outside the whiskers are outliers. Note: to visualize the data more effectively, the axes depicting FMC (%) were visually constrained to 150%, preserving all values while focusing on a more relevant range. The smoothed, marginal effects of understory cover, canopy cover, heat load index and precipitation on FMC transformed to show the fitted GAM function on the response scale. The x axis shows values of the covariate, the rug indicates the distribution of covariate observations, and the y axis shows expected FMC values. The gray bands correspond to the 95% confidence interval and represent model uncertainty in the transformed (response scale) estimate. Though negative values are not possible in FMC or under a Gamma distribution, the confidence interval below 0 in the precipitation plot is an artifact of transformation and reflects wide uncertainty.

Graph from a recent paper on widespread & intense surface air temperature is scary for many reasons including fire. Higher temperatures & more extreme heat will lead to more intense fires in many parts of the world largely due to drier fuels driven by increased vpd.
www.science.org/doi/10.1126/...
This figure shows that the fraction of Earth’s surface area with extremely hot days has increased since 1950. The red curves show the annual mean of relative fractional global surface area with ERA5 daily mean surface air temperatures exceeding 30° and 40°C: where Aref refers to the area over the period of 1951 to 1980 and was estimated to be 7,565,377 km2 for days hotter than 30°C and 4636 km2 for days hotter than 40°C. The blue curves mark the corresponding relative fractional global surface area with daily mean surface air temperatures of −30° and −40°C.

The climate crisis is fuelling extreme fires across the planet

In the past year, an area of land over 3.7 M km², larger than India, was burned worldwide. >100 M people were affected by these fires, and homes and infrastructure worth US$215 billion were at risk.
