the final bit of my PhD work is now out in ERL! we look at how recent trends in tropical Pacific SSTs contributed to forest fire & climate trends in the Southwest US vs Eastern Australia (two super fire-prone regions with opposite-signed ENSO teleconnections) 🔥🌬️ iopscience.iop.org/article/10.1...

Whew. All signs are increasingly pointing to a significant, if not strong to very strong, El Niño event. I'll have more to say in coming weeks & months, but for now I'll just say that this is increasingly likely to become a major regional-to-global climate driver in 2026-2027.

A new paper by @anaigmendez.bsky.social vin Geophysical Research Letters shows that the oxygen isotope ratio of the annual rings of tropical conifers in Central America records rainfall amount and tracks large-scale tropical atmosphere ocean dynamics! agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Excited to have this paper out showing a strong coupling between Central American tree-ring oxygen isotopes and ocean–atmosphere dynamics (interbasin SST gradients, ITCZ, CLLJ... ). Many thanks to all co-authors! agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Record-breaking humidity is on the rise, but it’s understudied relative to dry heat. New research takes a look.

Temperatures Are Rising, but What About Humidity? - Eos

Humid heat extremes are less frequently studied, but no less important, than those of dry heat.

Excited for this paper to be out! With the collaboration of met services from Central America, we evaluate in detail the biases in gridded products that arise from the underlying station data, and the effect this has on the apparent emergence of regional drying trends. Thanks to all the co-authors!

Rainfall data can be hard to come by in the tropics. @anaigmendez.bsky.social leads a new paper taking a deep dive into the quality and potential biases in gridded precipitation data in Central America. CHIRPS comes out ahead, but be wary of trends! agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Underwater photographer Brian Skerry encountered this white #shark while diving off of Maine earlier this month. It's not exactly new shark territory, but #WHOI's Camrin Braun says warming temps are pushing the species north. 📲Check out the rare encounter in NatGeo: go.whoi.edu/natgeoshark

Rare image of great white shark captured off the coast of Maine

National Geographic photographer Brian Skerry has logged more than 10,000 hours under water—but he's never before snapped a photo of a great white in Maine before.

Excellent talk this afternoon by @triptychphrases.bsky.social at #UArizona on reconstructing (using #biomarkers) and understanding mechanisms about more intense Pliocene monsoon storms in southwestern North America—and their relevance for future changes in this region.
