New first-authored #scientific #publication in @PNASNews with Edouard Bard (Collège de France and CEREGE)!
We revisit the #thermal bipolar seesaw using #PaleoTemperature records from the #IberianMargin!

What if celebrate #IWD2023 by featuring two recent #scientific #publications with female first authors and involving some of the #molecular #fossils that I studied during my #PhDThesis?
Robles et al. (https://doi.org/10.5194/cp-19-493-2023) and Barhoumi et al. (https://doi.org/10.1016/j.quascirev.2023.108014) reconstructed past #temperatures using #pollen and bacterial membrane lipids named #brGDGTs.
Indeed, membrane plasticity adjustments to #environmental changes also yield complementary #ClimateProxies.

It is time for my #introduction:
I am a #paleoclimate #scientist who also is an expert on #biomarkers as #ClimateProxies. In other words, I study past #climate using #molecular #fossils.
I am currently a #postdoc at the Institute of Environmental Science and Technology - Autonomous University of Barcelona (ICTA-UAB).
In addition to boosting toots of interest, I will essentially toot my new #scientific #publications and other #scientific content.

They use an ensemble of climate models to find the uncertainty of temperature and to see if the elevation changes can be deduced at the location of the ice cores. They find that standard deviation is on the order of over 300 m, meaning that it is unlikely that paleo-elevation can be reconstructed. #Paleoclimate #ClimateProxies #IceSheets https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2022GL100334

They find that the rainfall in Flores responded to some Heinrich Events, producing wetter conditions. The record also shows that the rainfall is affected by insolation changes. #paleoclimate #ClimateProxies https://www.nature.com/articles/s41598-022-21843-8
