Gavin Foster @thefosterlab.bsky.social · 01/09/2026I often despair about the state of our climate (especially after this summer), but this plot of high-end emission scenarios from successive IPCC reports is a welcome bit of good news and shows how far we have come. Still a long way to go but we have started. see www.carbonbrief.org/explainer-th.... 051

Gavin Foster @thefosterlab.bsky.social · 30/06/2026Happy Boron Day everyone! For those of you who have forgotten: on this day in 1808 French chemists Joseph Louis Gay-Lussac and Louis Jacques Thénard first isolated boron. Coincidently, 9 days later UK Chemist Sir Humphry Davy also isolated boron, so they share the credit en.wikipedia.org/wiki/Boron 1123
Gavin Foster @thefosterlab.bsky.social · 30/06/2026!New Paper Alert! Corals are thought to make their skeletons from amorphous calcium carbonate (ACC). @amoeba-lab.bsky.social and I show here that this is however not compatible with their chemical composition. www.geochemicalperspectivesletters.org/article2623/ 1/2 1135
Gavin Foster @thefosterlab.bsky.social · 08/06/2026Nice reminder that the legacy of anthropogenic climate change could be LONG. Notice here temperatures still elevated by 3000 CE even in the optimistic scenario's. From this paper: eur03.safelinks.protection.outlook.com?url=https%3A.... 🧪⚒️ 03813
Gavin Foster @thefosterlab.bsky.social · 09/04/2026Not as long a time-series as some others (e.g. ourworldindata.org/grapher/date...) but I just turned on my office fan in April! Perhaps too soon to definitively define a global warming trend... 3110
Gavin Foster @thefosterlab.bsky.social · 03/04/2026Wow - such a cool image from Artemis II. I love seeing the atmosphere on these sorts of images - such a fragile looking layer of gas but so important to all life on our planet 22412
Gavin Foster @thefosterlab.bsky.social · 30/03/2026@zifeiyang.bsky.social has been working hard on getting laser boron isotope analysis of individual benthic forams working and I am pleased to say her paper just came out: www.sciencedirect.com/science/arti... . Shows that single benthics can capture the evolution of T and pH on seasonal timescales 2307
Gavin Foster @thefosterlab.bsky.social · 26/03/2026Ever wanted to see how a coral skeleton grows? In this paper (led by: @jtrendbio.bsky.social) www.sciencedirect.com/science/arti... we use Live CT, a method of scanning live organisms using microCT, to visualise how the skeleton grew over about one month. 03721
Gavin Foster @thefosterlab.bsky.social · 28/01/2026Very effective illustration of what has happened to Florida's coral reefs in response to anthropogenic climate and environment change.

Gavin Foster @thefosterlab.bsky.social · 26/07/2025Eocene Fossil turtle shell from Yarmouth Isle of Wight (~30 Ma). It was a fossil like this that led to the birth of the science of Palaeoclimatology: in the late 17th C, IoW native Robert Hook proposed that such turtle fossils indicated the climate must have been warmer in the past. ⚒️🧪 26711

Gavin Foster @thefosterlab.bsky.social · 17/12/2024Depends on what you think! but yes, uncertainty in pre-industrial T is around +/- 0.25 (see this figure from this paper: www.nature.com/articles/s41...). Most of this uncertainty is down to ocean temperatures being poorly measured as technologies evolved from buckets to satellites 120
Gavin Foster @thefosterlab.bsky.social · 04/12/2024Happy Isotope Day everyone! 🥳On this day in 1913 Nature published Federick Soddy's paper "Intra-atomic Charge" www.nature.com/articles/092... in which he introduced the term "isotope" (coined after a dinner conversation in Glasgow with Margaret Todd the classics scholar). how will you celebrate?🧪⚒️🌊 69747

Gavin Foster @thefosterlab.bsky.social · 16/08/2024I agree, though mostly when people say that, they are talking about historical weather records, where we do have daily resolved data (and sometimes better). The records dont go back that far at a global scale. In the UK we have this though: www.metoffice.gov.uk/research/cli... 110
Gavin Foster @thefosterlab.bsky.social · 15/08/2024Some corals grow BIG. Check this one out - you can actually see it from space!! (from this website www.mapthegiants.com) 172
Gavin Foster @thefosterlab.bsky.social · 07/08/2024How hot future Earth will be depends on how much CO2 we emit and how sensitive the climate system is to radiative forcing. New paper by Eisenman and Armour (doi.org/10.1038/s414...) shows in a model that CS is state dependent, consistent with what we see in the geological record 🧪⚒️ 1127
