Hopefully not falling back to the #SnowballEarth of 700 to 650mya or worse the #MethaneEarth (I call that Planet Fracked) prior to #cyanobacteria.
Assuming that #nuclearwinter isn't full Snowball effect, it could be like #PETM (worse) or asteroid 66mya (only ~10 years cold) & leave some small rat.
The Paleocene-Eocene Thermal Maximum (PETM) is one of the closest analogues for modern global warming. A new study of plants response through migration and evolution sheds light on future adaptation and carbon cycling.

Ancient Ocean Shift Preceded PETM by 200,000 Years, Study Finds
University of Bremen researchers found a Southern Ocean ecosystem shift 200,000 years before the PETM (~56 million years ago) in sediment cores from the Campbell Plateau. Read more: getnews.me/ancient-ocean-shift-prec... #southernocean #petm
Our study on the role of the #PETM on the early evolutionary success of #salamandrids is out! Delighted to be part of this great project led by Loredana Macaluso, with A.Villa, @grumpydrfabre.bsky.social & B.Mennecart #salamanders #climatechanges 🌡☀️⌛️

A #PETM sized temperature perturbation
🤯 56M years ago, Earth rapidly warmed 5°C! Massive carbon release triggered a “hothouse” & reshaped life. A glimpse into our planet’s wild past! 🌍 #PETM

It took the climate 20,000 - 50,000 years to stabilize after the #PETM rise in global temperatures of 5 - 8 degrees Celsius 56 million years ago. #ClimateChange #environment #stewardship www.science.org/doi/10.1126/...
Many thanks to those that attended my first #EGU25 talk in-person and online on the driver's of #PETM shelf deoxygenation!
Attending the #EGU25 conference in Vienna this week? Pop by my oral presentation in session CL4.18 - Ocean Oxygen Changes Through Time: Proxies, Models and Environmental Impacts, in room 0.31/32 on Thursday, 1 May 2025, from 14:15 on the latest #PETM research coming out my PhD:

+1.5°C is not the end. We are currently on track for +3°C by 2100 and #PETM levels of warming (~+5°C) under some weak emissions sceanrios by 2500. We need to act faster to curb the amount of warming projected for our current Anthropogenic "hyperthermal" 🌡️📈

Imaging #PETM stress tolerant, low oxygen benthic foraminifera today on the #SEM at the University of East Anglia
Fun day participating in the UK IODP Achievements and Legacy conference at The Geological Society , Burlington House. We have used an orbitally tuned age model from #IODP legacy material ODP 1262 to date our shallow marine #PETM records helping us disentangle sea level and climate changes
Had great fun today getting to use our #SEM at the University of East Anglia to image some #PETM benthic foraminifera. Even down to the scales of individual pores and the odd nannofossil!🔬🐚📸😃

Das Bild stammt aus der Wikipedia und zeigt die Temperaturkurve während der PETM Das Paläozän/Eozän-Temperaturmaximum (PETM) vor etwa 55,8 Millionen Jahren war eine nach geologischen Maßstäben sehr kurze, aber extreme Erwärmungsphase, deren Dauer je nach wissenschaftlicher Analyse auf 170.000 bis 200.000 Jahre veranschlagt wird. Der damalige globale Temperaturanstieg erfolgte auf der Basis eines bereits vorhandenen Warmklimas und war mit einem stark erhöhten Eintrag von Treibhausgasen in die Erdatmosphäre und Weltmeere verbunden. Während des PETM stieg die globale Temperatur innerhalb von wahrscheinlich 4.000 Jahren um durchschnittlich 6 °C (nach anderen Studien kurzzeitig um bis zu 8 °C) von etwa 18 °C im späten Paläozän auf mindestens 24 °C am Beginn des Eozäns, wobei eine neuere Analyse erheblich höhere Werte veranschlagte.
Mit einem haben die Klimaleugner der AfD ja recht: Klimawandel gab es schon immer. Wir steuern Richtung #PETM. Es gibt erschreckende Übereinstimmungen. Die Doku macht nicht wirklich Spaß.

Interested in the origins of #blackshales and shelfal responses to #PETM abrupt warming? Come along to my #GGRiP24 talk on 11th April to find out more!!! 🌊🌦️🪨🐚
At #NGWM2024, Morgan Jones presented our poster on the #ICDP project "PVOLC: Volcanic forcing and Palaeogene climate change". This project aimed at obtaining a core drilling through the #PETM and Paleogene strata at Fur in Denmark is currently on hold awaiting a Danish membership in ICDP. 💉⚒️
When examined in the geological record, will the anthropogenic warming signal be distinguished from that of the last deglacial warming? For comparison the onset of the #PETM is estimated between ~3-20kyr🤔
Interesting read with a lot of references to the #PETM
Still interested in how #micropalaeontology can be used to track how changing environmental systems can trigger marine tipping points? My #TMS23 talk on the #PETM is now also available to view in the following link below🐚🌊⚖️🌡️:

Starting the first leg of my journey from Norwich to Southampton to attend and present at the Micropalaeotology Society Annual Conference 2023 #TMS23 #PETM #Forams 🤩🐚📈
Did you know micropaleontology can be used to track changing environmental systems which can trigger marine tipping points? Looking forward to presenting some #PETM findings at the upcoming Micropalaeontology Society Annual Conference this week!🐚📈
Home with a bad cold watching SevKender giving an Earth-talk at Geology_UCPH on Hg, LIP volcanism and the #PETM. Thankful for technology 😊🤧🌿#NAIP ⚒💉
This is the first of many @Leilanoxia papers to come from her PhD thesis. There was some hard work and tough thinking behind this paper - congratulations! And onwards to the #PETM.
(Also, she'll be defending soon and looking for postdocs!)
At #DeepMIP @climategordon of @ogu_bristol @cabotinstitute shows new records of terrestrial warming across the #petm. A hot world got hotter - across all archives.
PhD defence next thursday #PETM #biomarkers #isotopes
