I am pleased to announce that we are inviting applications for a Lead Laboratory Coordinator at the University of Arizona’s Laboratory of Tree-Ring Research. Review of applications will begin on September 15, 2026. For details and to apply, visit arizona.csod.com/ux/ats/caree...

Water Limits Radial Tree Growth More Than Light in an Everwet Subtropical Forest onlinelibrary.wiley.com/doi/10.1111/...

Water Limits Radial Tree Growth More Than Light in an Everwet Subtropical ForestWe deployed automated point dendrometers on 35 trees representing three life history strategies in an everwet subtropical forest with 3500 mm rain annually and no pronounced dry season. Contrary to t....onlinelibrary.wiley.com

This is important - Honest Brokers (TM) and their echo chamber will often point to the decreasing global wildfire, but that reflects changing human land use practices. In temperate and boreal forests, climate's role is more clear. See this paper by Cunningham et al. www.nature.com/articles/s41...

Increasing frequency and intensity of the most extreme wildfires on Earth - Nature Ecology & EvolutionAnalysis of fire radiative power derived from satellite data finds that the frequency of extreme fire events increased 2.2-fold from 2003 to 2023 and that these increases were mostly driven by extreme...www.nature.com

Was curious how ENSO forecasts did during the 2023-2024 El Nino event. The model plume bracketed the eventual NINO3.4 trajectory fairly well, with some outliers in both directions (e.g. AUS-ACCESS, MetFrance, BCC, CPC Markov) - data from IRI: iri.columbia.edu/our-expertis...

The Meadowlands had extensive areas of Atlantic White Cedar (Chamaecyparis thyoides) forest as recently as the late 1700s (Pearl et al. 2020).

'Our findings indicate that more severe fire effects are expected in Canada because of the warming climate' www.science.org/doi/10.1126/...

Canadian forests are more conducive to high-severity fires in recent decadesCanada has experienced more-intense and longer fire seasons with more-frequent uncontrollable wildfires over the past decades. However, the effect of these changes remains unknown. This study identifi...www.science.org

Drivers and Impacts of the Record-Breaking 2023 Wildfire Season in Canada - Nature CommunicationsThe record-breaking 2023 wildfire season in Canada ( ~ 15 Mha burned) was enabled by early snowmelt, drought, and extreme weather.
