New special collection just went live! Happy to chat about it, but the short version of benefits are: rolling publications (as ready) and increased citations (by being “grouped”) and multiple involved AGU journals! Got gateway papers coming? Think about submitting your work here!

The Definitive Guide to the TEX86 Paleothermometer

The marine sedimentary biomarker pool receives membrane lipids from multiple archaeal groups and sources living throughout the water column and sediments, as well as bacterial lipids from marine and terrestrial sources. Understanding the contribution of these different inputs is essential for interpreting TEX86 paleotemperatures and other lipid-based paleoclimate proxies. Credit: Elling et al. [2026], Figure 13

Does anyone have informed perspectives on this paper? Seems important if true, important to refute if false. "Our results provide the first observational evidence that low clouds have partially offset recent warming, ... " agupubs.onlinelibrary.wiley.com/doi/10.1029/...

In this study, we combined satellite observations, reanalysis data sets, and a cloud-controlling factor (CCF) framework to quantify historical low-cloud cover (LCC) variability and its associated feedbacks. By harmonizing 13 long-term satellite data sets using anomalies and extending the record back to 1979 using CCF-based reconstructions, we constructed a physically grounded and temporally consistent record of LCC variability. The CCF method reproduces observed LCC anomalies well (𝑟 =0.85
for 1982–2024; 𝑟 =0.93
for 2001–2020), lending confidence to both the reconstructed record and the associated historical trends.

Across all data sets, tropical ocean LCC increased robustly since 1979 at a rate of 0.18 ±0.07%
per decade over 1979–2025, concurrent with approximately 1,K
of global surface warming (0.21 ±0.03%
per decade). When normalized by the temperature trend, this corresponds to 0.85 ±0.32%,K−1
, with stratocumulus regions accounting for nearly 90%
of the signal. Using observed 𝑑⁢𝐶⁢𝑅⁢𝐸/𝑑⁢𝐿⁢𝐶⁢𝐶
relationships, this translates into a strongly negative low-cloud feedback of −0.79 ±0.3,W,m−2,K−1
, in contrast to the positive feedback observationally inferred from idealized abrupt-4×CO2
experiments (0.50 W m−2 K−1
in this study and 0.42 −0.56 W m−2 K−1
in Cesana and Del Genio (2021); Myers et al. (2021)).

In digging through old taxonomy works to ascertain this or that detail of taxonomical history, I sure wasn't expecting a Star Wars-type text crawl of author accolades. From Daniel Giraud Elliot's "A review of the primates" vol. II (1913), www.biodiversitylibrary.org/item/39494#p...

Partial screenshot of a scan of the title page of the monograph "A Review of the Primates", vol. II by Danial Giraud Elliot (1913) hosted by Biodiversity Heritage Library. It reads:

This is really interesting. The common cause (of evolution, taphonomy) does deep: "Monsoon-driven storms created a Cretaceous dinosaur Lagerstätte. Microbial mats enabled rapid sealing and exceptional soft-tissue preservation." www.sciencedirect.com/science/arti... 🧪 ⚒️ #Geology #Paleobio

Depositional model and facies details of the VdP deposits. (A) Reconstructed sequence of events: (Top) High-energy cyclonic events transport terrigenous debris, plant matter, and tetrapod carcasses across undisturbed tidal flats. (Middle) Coarse sediment settles to form a storm layer, rapidly stabilised by microbial mat draping; sinking vertebrate carcasses create impact deformation structures in the soft substrate. (Bottom) Resumption of tidal rhythms immediately buries isolated bones and debris, while articulated carcasses retain soft tissue, progressively buried by onlapping laminae over multiple tidal cycles. (B) Photomicrograph showing the typical fine, undisturbed rhythmic couplets. (C) A photographic detail illustrating an event bed, overlain by distinctive microbial draping structures.

🚨📜🚨 What did the western Siwalik landscape look like ~1.2 million years ago? Led by A.P. Kaur, we (+@amjukar.bsky.social et al.) have a new paper out using #fossil teeth from the Haro River Quarry—a hyena den—to reconstruct #mammal diets & #vegetation during the early #Pleistocene 🦷 🌾 🔨 (1/4)

Map of South Asia showing the Haro River Quarry in northern Pakistan, alongside nearby Pleistocene sites and modern rainfall patterns; adjacent stratigraphic and magnetic-polarity records locate the fossil bone bed at about 1.2 million years ago.

Two panels compare carbon and oxygen isotope values from Haro River Quarry fossils with older Siwalik soil-carbonate records. The red diamonds at ~1.2 million years ago show a much wider range of values than the regional records, revealing diverse diets and local habitats within a broadly grassland-dominated landscape.

It's out. My latest feature for @science.org, from aboard the RRS Discovery: a deep look at the past, present, and future of AMOC, told through the RAPID program. AMOC is weakening -- maybe, probably. But it also may be more resilient than some have made it seem.
