Very excited to share that I have accepted a @centa.bsky.social funded PhD in wildfire science working with supervisors from the @unibirmingham.bsky.social, @exeter.ac.uk, and @thompsonriversu.bsky.social. After two seasons as an IA firefighter with BCWS, I’m looking forward to this next chapter 🔥

Expect lots of fire activity in central Manitoba and NWRN Ontario over the next week. Lots of out-of-control fires in the region (red and purple dots below), some active already today (GOES-East 3.9 micron band - white & red active fires) and the prec. forecast has little to no rain in the region.

Most recent Sentinel-2 overpass captures the full extent of the western İzmir complex. Originating near Orhanlı on June 29, two separate fires spread more than 13km south in 2 days, driven by northeasterly winds, nearly converging near Ürkmez. Total area burned >10,000 ha.

Sentinel-2 imagery captured 24 hours ago shows widespread burning originating near Kavakdere and extending south through Orhanlı, Payamlı, and Doğanbey, reaching Ürkmez town and crossing the Kuşadası-Seferihisar highway. Next Sentinel pass expected in 23 hours.

Captured at 11:56 TRT, 30 June 2025.

This Meteosat-9 GeoColor satellite image with VIS (0.635 µm) and IR (3.9 µm) band overlays shows fire activity from the Western İzmir Complex and Manisa-Akhisar blaze intensifying into the evening with smoke drifting west over the Aegean.

My parents are currently sheltering on a beach along the coast, waiting this out.

They evacuated earlier today as the Western İzmir Province Complex in Türkiye advanced through the hills between Seferihisar, Payamlı, and Ürkmez.

Roads closed and power out across the region.

Updated figure from Jain et al. showing global extreme fire weather trends since 1979. Metrics are global 95th percentile of annual Fire Weather Index (FWI), Initial Spread Index (ISI) and the Vapor Pressure Deficit (VPD). The trend is clear - we are seeing more extreme fire weather due to warming.

Found in Jasper. Anyone else see what I see?

Area burned for BC is almost 500,000 hectares so far this year. Compared with annual area burned in BC 1950-2024, 2025 is already in 7th place (1950-2025) with much of the fire season ahead of us. The years in red 2017-2025 have more area burned than the years in green (1950-2016).

2025’s off to a hot start. And that 2023 line is wild... and it marks my rookie season as a wildland firefighter, what a year.

Area burned over 1 million hectares in Canada and increasing. Second only to the 2023 in terms of area burned for this time of year. @ciffc.bsky.social
