Time series plot depicting predicted Nino 3.4 region ocean temperature anomalies from the latest (Mar 2026) ECMWF ensemble. It depicts an extremely rapid rise in such temperatures, from modest negative anomalies to strong positive anomalies, by mid-summer 2026--indicative of a transition from weak-moderate La Nina conditions to moderate-strong El Nino conditions over just a few months.

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.

Oxygen Isotopes in Tree Rings Track Neotropical Climate Dynamics Tree-ring δ18O from Abies guatemalensis in Central America captures interannual variations in boreal summer rainfall Lighter δ18O years are associated with a weakening of the Caribbean Low-Level ...

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!

Temperatures Are Rising, but What About Humidity? - Eos Humid heat extremes are less frequently studied, but no less important, than those of dry heat.

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!

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.

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.

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.

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.

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.
