Thanks to @uwenvironment.bsky.social news team for resurfacing this interview from a couple years ago.

Helpful and still very relevant context RE trends (and drivers of trends) in wildfires, especially given much of the broader dialogue around fires so far this summer across the n. hemisphere.

Sequoia sempervirens (redwood; world's tallest tree) is well adapted to high-intensity crown fires (eg 2020), but Sequoiadendron giganteum (giant sequoia; world's most massive tree) is adapted to surface fires only!

climate change has substantially increased the frequency and severity of such “disaster weather”"
dx.doi.org/10.1126/science.adr5127

Points show the percentage of days (FWI and VPD) and months (PDSI) in each year at the disaster locations that exceeded the 97.5th percentile value (which corresponds to mean FWI max during the disasters). calculated over all days from 1980 to 2023. The blue line shows the fit of a generalized additive model.
