Towards the middle of the century, ~4000 glaciers worldwide will disappear every year.
Peak glacier extinction in the mid-twenty-first century - Nature Climate Change
Many mountain glaciers will disappear with warming. Here the authors assess how many glaciers will disappear per year under different warming scenarios, finding that a peak in glacier loss will happen...

Could rising antimicrobial activity in warmer soils make microbes less efficient at using carbon & push more CO₂ into the atmosphere?

Our new work in @isme-microbes.bsky.social explores how the combined effects of warming & AMR may alter microbial C processing

I'm delighted our paper is out: doi.org/10.1093/isme...
With new SAR11 isolate genomes and time-series metagenomes, we reveal coastal and offshore SAR11 ecotypes, identify associated metabolic traits, and pinpoint selective gene sweeps as a likely evolutionary driver to niche partitioning. 🌊🦠
Habitat-specificity in SAR11 is associated with a few genes under high selection
Abstract. The order Pelagibacterales (SAR11) is the most abundant group of heterotrophic bacteria in the global surface ocean, where individual sublineages

Páramo of Iguaque ⛰️
Challenging 3 hour sunrise climb at ~3,600 m.a.s.l. carrying batteries, tripods, samplers, PPE - but so worth it to sample amongst the frailejones 🤩
Hugely grateful to Santuario de Flora y Fauna de Iguaque for allowing us to work in this sacred place
