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!
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.
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!

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) 🔥🌬️

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.

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.

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/...

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/...

There are significant differences between gridded precipitation products in Central America in both variability and trends CHIRPS consistently outperforms Global Precipitation Climatology Centre ...
