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.

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!

If you are at #AGU25 I shall be presenting a new reconstruction on Indian Summer Monsoon over the last millennium using speleothem records. agu.confex.com/agu/agu25/me...

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

The seasonality of the Amazon water cycle is intensifying. -> Bruno Cintra and colleagues use decades of oxygen isotopes in tree rings to show how the dry season has got drier, and the wet season wetter. www.nature.com/articles/s43...

A new observational benchmark for equatorial upwelling @usclivar.bsky.social Research Highlight Our general tendency to underestimate equatorial upwelling may offer a clue into the disagreement between historical trends and climate model simulations of Pacific SSTs. usclivar.org/research-hig...

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.
