Prof Ceri Lewis

Who's at #AGUOceanSciences in Glasgow? Come and chat microplastics and Galapagos with me at poster 151 this afternoon 4-6.

Still time to apply for this PhD with us 😀

Another exciting PhD opportunity to come and join our @exetermarine.bsky.social Microplastic research team through the NERC Red Alert programme: shorturl.at/zAS2a

AMOC weakening declared a national security threat Iceland has declared the AMOC a national security threat and an existential risk in the coming decades, enabling its Government to prepare for worst-case scenarios. Should we be worried?

The latest research confirms AMOC weakening together with a tipping point that is getting closer and closer. Governments are starting to notice with Iceland the first to declare it a national security threat.

‘Deathly silent’: two out of three corals in world heritage-listed Ningaloo reef have been killed, scientists confirm One expert says she is ‘starting to visualise the point where all we have left of corals and reefs is memories’

I'm so, so tired of reading, reporting on and seeing these results. This was easily one of the prettiest places in the world, forever changed.

A Quantitative Environmental Risk Assessment for Microplastics in Sewage Sludge Applied to Land The application of sewage sludge to land delivers high levels of microplastics (MPs), contributing to soil contamination and chronic effects on soil biota. Despite this, the quantitative chronic risk ...

Coral reefs, ice sheets and Amazon rainforest approaching a tipping point due to global heating, report says Unless global heating is reduced to 1.2C ‘as fast as possible’, warm water coral reefs will not remain ‘at any meaningful scale’, a report by 160 scientists from 23 countries warns * Sign up for climate and environment editor Adam Morton’s free Clear Air newsletter here The earth has reached its first catastrophic tipping point linked to greenhouse gas emissions, with warm water coral reefs now facing a long-term decline and risking the livelihoods of hundreds of millions of people, according to a new report. The report from scientists and conservationists warns the world is also “on the brink” of reaching other tipping points, including the dieback of the Amazon, the collapse of major ocean currents and the loss of ice sheets.

an event poster. the main image is a black and white photograph of a stranded, deceased killer whale, laying on its side on the sand of a beach setting. overlay text reads ' signals from the shore: what cetacean strandings reveal about pollution. weds 15th oct, huxley lecture theatre, zsl, 6-7.30pm, FREE.' there are logos for ZSL and CSIP at the top.

What can strandings of cetaceans tell us about the impact of marine pollution? 🐬

This @zslofficial.bsky.social and CSIP event, brings together experts (including our @sarahenelms.bsky.social) to explore major forms of marine pollution in our waters.

An image with a dark blue background features a single glowing orange jellyfish in the centre. Around it is simple, dashed-line drawings of various marine animals, including a shark, different types of fish, and small schools of fish. In the top half of the image, white text reads, “About 91% of ocean species are yet to be discovered.” Below, more white text says, “60 countries have just made history to protect their future.” In the bottom right corner, there is a logo of the European Commission.

The tide has turned for our oceans.

60 countries have ratified the High Seas Treaty, entering into force in early 2026.

A historic first to protect biodiversity beyond national waters through marine protected areas, enforceable sustainability, and shared responsibility ↓

High Seas Treaty Ratification Tracker At least 60 countries must sign and ratify the High Seas Treaty for it to become international law. Join the #RaceForRatification. Ask leaders to ratify the Treaty Now!

At yesterday's 80th @UN General Assembly, the High Seas Treaty was FINALLY ratified! 🌊 🦑

Aka the Biodiversity Beyond National Jurisdictions (BBNJ) Agreement, it now officially enters into force in 120 days, becoming international law in Jan 2026.

"Health losses attributed to anthropogenic climate change," a brief communication in the journal Nature Climate Change. There's a map showing regions of the world, and pie charts of relevant studies as they apply to different health impacts like "heat-related deaths" and "maternal and child health"

🚨 NEW: Climate change is already causing 30,000 deaths per year - a global annual economic loss of $100-350B USD - but the true damage is probably 10x higher. Out TODAY in Nature Climate Change: the first systematic look at the science of "health impact attribution" 🔓 www.nature.com/articles/s41...

Interesting findings from @samuelmacaulay.bsky.social presenting his findings with MRES students on enhanced rock weathering as a Carbon Dioxide Removal tool and it's effects on riverine benthic species under experimental conditions with addition of rock material 👍🏻

#BlueCarbon #CDR

Great talk from @drplanktonpoo.bsky.social Krill Poo may sequester as much #carbon as mangroves AND we're messing that up by fishing them out. The fishery near Antarctica shut early for the first time ever due to record catch numbers (because of more fishing) @bes-aquaticgroup.bsky.social

A teal flyer for a PhD opportunity to investigate how warming may change antimicrobial resistance. The project will use experiments on Klebsiella bacteria to answer questions about how temperature affects their response to antibiotics, plasmid transfer, and fitness costs. The research involves microbiology lab work, bioinformatics, and mathematical modeling. The flyer includes contact details for Dr. Daniel Padfield and the logos of the sponsoring institutions.

I have an MRC-funded PhD project available (www.exeter.ac.uk/study/fundin...) on how warming will change the problem of AMR. Join a small and friendly group (padpadpadpad.netlify.app/about) in (sometimes) sunny Cornwall. 🧪🦠 #microsky
